The Importance of a Well-Maintained Chimney


A properly functioning chimney is crucial to your Toronto home’s safety, comfort, and energy efficiency. Regular maintenance and prompt repair services can prevent potential hazards, help avoid expensive repairs, and ensure that your heating system operates at optimal levels. Some of the key reasons for maintaining a well-functioning chimney are:


  1. Fire Safety: A clean chimney minimizes the risk of chimney fires caused by the accumulation of combustible materials such as creosote in the flue.


  1. Carbon Monoxide Prevention: A chimney in good condition allows for the proper venting of harmful gases, including carbon monoxide, ensuring a safe indoor environment for your family.


  1. Energy Efficiency: A well-maintained chimney ensures that your heating system can effectively heat your home, improving energy efficiency and reducing utility costs.


  1. Structural Integrity: Regularly inspecting, repairing, and maintaining your chimney contributes to the overall structural integrity of your home.


Common Chimney Issues and Their Causes


Several common issues can affect your chimney’s performance and integrity. Identifying and addressing these problems promptly can help maintain your home’s safety and structural stability. Some common chimney issues include:


  1. Creosote Build-Up: Creosote is a highly combustible material that forms as a byproduct of burning wood. When it accumulates in your chimney flue, it can cause chimney fires and obstruct the proper venting of gases.


  1. Damaged Flue: A cracked or damaged chimney flue can let heat, smoke, and gases escape into your home, leading to possible health risks and even house fires.


  1. Masonry Damage: Crumbling or damaged masonry can compromise the structural stability of your chimney and allow water to penetrate the structure, leading to further damage.


  1. Chimney Cap and Crown Problems: A damaged or missing chimney cap or crown can expose your chimney to the elements, leading to water infiltration and the risk of pest infestations.


  1. Blocked Chimney or Flue: Obstructions such as animal nests, debris, or blockages from collapsed chimney liners can prevent the proper venting of smoke and harmful gases.


Signs Your Chimney Needs Repair or Replacement


It is essential to regularly inspect your chimney for any signs that repair or replacement may be needed. Common indicators that your chimney may require professional attention include:


  1. Visible Cracks or Damage: Cracks or damage in the chimney, bricks, mortar, or flue tiles can indicate a need for repair or replacement.


  1. Rust or Discolouration: Rust on your chimney cap, fireplace, or flue may signal a moisture problem inside the chimney.


  1. Smoke or Odours: If smoke or strong odours are present in your home whenever you use your fireplace, this could be a sign of a blocked or damaged flue.


  1. White, Powdery Build-Up: Efflorescence, a white, powdery substance on the chimney’s exterior, can be a sign of excess moisture trapped within the structure, requiring attention.


  1. Deteriorating Mortar Joints: If the mortar joints between bricks or stones are crumbling or deteriorating, this can compromise the chimney’s structural stability.


The Chimney Repair Process: Step-by-Step Guide


The process of repairing a chimney depends on the specific issue being addressed but generally involves several key steps:


  1. Assessment: A professional chimney technician from a trusted company like Red Robin Masonry will inspect your chimney, diagnose the issue, and determine the most effective course of action for repair.


  1. Cleaning: Before any repairs can be made, the chimney must be cleaned thoroughly to remove any soot, debris, or blockages.


  1. Structural Repairs: Any necessary structural repairs, such as tuckpointing, flue tile replacement, or brick and masonry work, will be performed by the chimney professional.


  1. Sealing and Waterproofing: Sealing and waterproofing the chimney can help protect it from water damage and extend its lifespan.


  1. Chimney Cap and Crown Repair: Damaged or missing chimney caps and crowns will be repaired or replaced to protect the chimney from water infiltration and pest infestations.


  1. Final Inspection: After completing the repairs, the chimney technician will perform a final inspection to ensure that all issues have been addressed, and the chimney is safe and functioning correctly.


Tips for Keeping Your Chimney in Good Condition


Regular maintenance is vital to preserving your chimney’s safety and performance. Some key tips for keeping your chimney in good shape include:


  1. Annual Inspections: Schedule a professional chimney inspection once a year to ensure any issues are identified and addressed promptly.


  1. Regular Cleaning: Have your chimney cleaned as needed, typically after burning one or two cords of wood, to prevent creosote build-up and other common issues.


  1. Install a Chimney Cap: Installing a chimney cap can help prevent debris, water, and pests from entering your chimney.


  1. Waterproofing: Consider having your chimney waterproofed to protect against water damage and costly repairs.

Chimneys are essential to any home with a fireplace or wood-burning stove. However, the bricks that make up the chimney can deteriorate over time, leading to crumbling or spalling. These issues can lead to more significant problems, such as chimney fires, carbon monoxide poisoning, and structural damage. This article will discuss the causes of crumbling or spalling chimney bricks, how to prevent it, and what to do if it has already occurred.


Causes of Crumbling or Spalling Chimney Bricks


There are several reasons why chimney bricks might start to deteriorate. One of the most common causes is exposure to water. Water can seep into the bricks and cause them to expand and contract, leading to cracks and ultimately crumbling or spalling. Another cause is exposure to extreme temperatures. If the chimney is not properly insulated, the bricks can crack and break down when exposed to high heat. Finally, age and wear and tear can also contribute to the deterioration of chimney bricks over time.


Preventing Crumbling or Spalling Chimney Bricks


The best way to prevent chimney bricks from crumbling or spalling is to take steps to protect them from water and extreme temperatures. Installing a chimney cap is one of the most effective ways to protect your chimney. A chimney cap covers the top of the chimney and prevents water, animals, and debris from entering the chimney. Additionally, adding insulation to the chimney can help to prevent cracking and breaking due to exposure to high heat. Regular maintenance, including cleaning and inspection, can also help to identify any potential issues early on and prevent further damage.


Repairing Crumbling or Spalling Chimney Bricks


If chimney bricks have already started to deteriorate, there are several options for repair. One option is to replace the damaged bricks entirely. This can be a time-consuming and expensive process, but it is often the most effective way to repair the chimney and prevent further damage. Another option is to use a sealant or coating to protect the bricks and prevent further deterioration. This can be a good option for minor damage or as a preventative measure. Finally, adding a chimney liner can also help to protect the bricks and prevent further damage.


Hiring a Professional for Chimney Repair


While some homeowners may feel comfortable attempting to repair their chimneys themselves, it is often best to hire a professional. Chimney repair can be a dangerous and complicated process, and it is important to ensure that the repair is done correctly to avoid further damage or injury. A professional chimney repair service will have the expertise and equipment needed to safely and effectively repair the chimney.




Crumbling or spalling chimney bricks can be a serious issue for homeowners. However, with proper prevention and repair, it is possible to protect the chimney and prevent further damage. Homeowners should protect their chimneys from water and extreme temperatures and seek professional help if the chimney has already started to deteriorate. By taking these steps, homeowners can ensure that their chimney remains functional and safe for years to come.

Your chimney is important to your home’s heating system, and maintaining it is critical for your safety and well-being. However, numerous homeowners often neglect the significance of maintenance until it becomes an urgent issue. A damaged chimney can lead to various problems, including health hazards and property damage. Here are the top signs that your chimney needs repairing and why you should call for repair services immediately.


  1. Cracks in the Chimney 


A clear indication that your chimney requires maintenance is the appearance of gaps or openings in its bricks or mortar. These gaps may result from several factors, such as weather elements, aging, or incorrect installation. If left unaddressed, they can worsen over time and lead to structural damage, which can compromise the chimney’s integrity and lead to safety hazards.


Chimney repair services can fix these cracks by filling them with a special mortar that matches the colour of the existing one, making them almost invisible. This process not only restores the chimney’s structural integrity but also enhances its aesthetic appeal.


  1. Damaged Chimney Crown


The chimney crown is the topmost part of the chimney that prevents rainwater, snow, and debris from entering the chimney flue. However, over time, the crown can crack or deteriorate, which can lead to water damage and leaks. If you notice water stains on the ceiling or walls near the chimney, it’s a sign that the crown needs repairing.


Chimney repair services can repair or replace the damaged chimney crown, depending on the extent of the damage. A new crown will not only prevent water damage and leaks but also extend the chimney’s lifespan and improve its performance.


  1. Chimney Blockage


A blocked chimney is a serious safety hazard that can lead to carbon monoxide poisoning, chimney fires, and other health risks. The blockage can be caused by various factors, including bird nests, debris buildup, and creosote buildup. If you notice that smoke is backing up into your home or that there’s a strong smell of smoke, it’s a sign that your chimney is blocked.


Chimney repair services can remove the blockage by using specialized equipment and techniques, such as cleaning, sweeping, and inspection. They can also install a chimney cap to prevent debris and animals from entering its flue.


  1. Chimney Leaks


A leaky chimney can cause significant water damage to your home, including ceiling and wall stains, mould growth, and structural damage. The leaks can be caused by various factors, including damaged flashing, cracked chimney crowns, and damaged chimney liners. If you notice any signs of water damage near your chimney, it’s a sign that your chimney is leaking.


Chimney repair services can identify the source of the leaks and fix them by repairing or replacing the damaged components. They can also waterproof the chimney to prevent future leaks and water damage.




A damaged chimney can pose significant safety and health risks to your home and family. Therefore, it’s essential to know the signs that your chimney needs repairing and call for chimney repair services immediately. Experts in this field possess the necessary abilities, expertise, and tools to fix and maintain your chimney, guaranteeing your security, well-being, and tranquillity. Tackling these problems as soon as you can will help prevent costly repairs and prolong your chimney’s lifespan.

The Risks of Using a Damaged Chimney and How to Address Them


A fireplace can be a charming, cozy addition to your home, providing warmth and ambience for you and your loved ones during the cold months. However, ensuring that your chimney is well-maintained and in good condition is essential to avoid serious risks to your health and your home’s safety. 


In this blog, we will discuss the risks of using a damaged chimney and provide helpful tips on addressing these issues to keep your home safe and secure.


Risks of Using a Damaged Chimney


  • Chimney Fires


One of the top dangerous risks of using a damaged chimney is the potential for chimney fires. When creosote, a highly flammable byproduct of burning wood, accumulates on the walls of your chimney, it can easily ignite and cause a chimney fire. A cracked or damaged chimney liner can also allow heat and sparks to escape, igniting nearby combustible materials and causing a house fire. Chimney fires can spread quickly and cause significant damage to your home or even result in injury or death.


  • Carbon Monoxide Poisoning


Carbon monoxide (CO) is a deadly, odourless, and colourless gas produced during the combustion of fuels like wood, charcoal, and natural gas. A damaged chimney can cause poor ventilation, allowing CO to accumulate in your home instead of safely venting outside. Prolonged exposure to high levels of CO can lead to severe symptoms such as headache, dizziness, nausea, confusion, and eventually death. Ensuring your chimney is properly working is crucial to preventing CO poisoning.


  • Structural Damage


Damaged chimneys can also cause structural damage to your home. Cracks or gaps in the chimney structure can let water seep in, leading to wood rot, mould growth, and other water-related damages. Additionally, a leaning or unstable chimney can lead to significant issues with your home’s foundation and support structures. Addressing these problems as soon as they are detected is essential to prevent chimney repair services, chimney removal, and potential risks to your home’s structural integrity.


  • Decreased Heating Efficiency


A damaged chimney can affect your fireplace’s heating efficiency, wasting energy and higher heating costs. Poor ventilation, cracks in the chimney liner, and other issues can cause your fireplace to work harder to produce heat, resulting in increased fuel consumption and decreased overall efficiency. Ensuring your chimney is in good condition can help maximize your fireplace’s performance and save you money on heating costs.


How to Address Damaged Chimneys


  • Regular Inspections and Cleanings


The first step in addressing and preventing chimney damage is to schedule regular inspections and cleanings. The National Fire Protection Association (NFPA) suggests having your chimney inspected at least once a year by a professional sweep. Regular inspections can help identify issues like creosote buildup, cracks, and other damage early on, allowing you to address them before they become more significant problems.


  • Repair or Replace Damaged Components


If your chimney inspection reveals damaged components, repairing or replacing them as soon as possible is essential. Cracked or damaged chimney liners should be returned to ensure proper ventilation and prevent heat and sparks from escaping. Any cracks or gaps in the chimney structure should be repaired to avoid water damage and maintain your home’s integrity. Call for chimney repair services for this kind of prevention.


  • Install Carbon Monoxide Detectors


To keep your family away from the dangers of carbon monoxide poisoning, installing CO detectors throughout your home is essential. These devices can alert you to high levels of CO, allowing you to take action and ensure proper ventilation. Remember to test your CO detectors regularly and replace the batteries as needed.


  • Consider a Chimney Cap


Installing a chimney cap can help prevent water damage, keep debris and animals out of your chimney, and improve ventilation. A chimney cap is a relatively inexpensive and straightforward addition that can provide significant benefits for your home’s safety and chimney performance.




Your home’s chimney ensures your fireplace’s safe and efficient operation. By understanding the risks associated with damaged ducts and taking the necessary steps to address and prevent these issues, you can enjoy the warmth and ambience of your fireplace while keeping your home and family safe. Don’t take chances with your safety – make chimney maintenance a priority for your home.

As a homeowner, keeping your chimney in the best condition is essential to prevent potential hazards. Chimneys are a fundamental component of any home, and they play a vital role in ensuring the safety and comfort of your family. Therefore, it is essential to understand the basics of chimney maintenance to keep your home safe and secure.


In this article, we will discuss the chimney basics every homeowner needs to know, including the importance of regular chimney maintenance, common chimney problems, and the best chimney repair services in Toronto:


Why Is Regular Chimney Maintenance Important?


Regular chimney maintenance is crucial to ensure your chimney is functioning correctly and also prevent potential hazards. A well-maintained chimney can also help improve your heating system’s efficiency and reduce energy costs.


One of the primary reasons to keep your chimney in good condition is to prevent a chimney fire. Chimney fires can occur due to a buildup of creosote, a highly flammable substance that accumulates inside the chimney. If left untreated, creosote buildup can cause a chimney fire, which can be extremely dangerous and cause significant damage to your home.


Regular chimney maintenance can also help identify potential problems early on, such as cracks, leaks, or blockages, before they become more severe and require more extensive repairs.


Common Chimney Problems


There are several common chimney problems that homeowners may encounter, including:


  1. Creosote buildup: Creosote is a highly flammable substance that can accumulate inside the chimney over time. Having your chimney cleaned regularly is essential to remove any creosote buildup and reduce the risk of a chimney fire.


  1. Cracks and leaks: Over time, the mortar and bricks that make up your chimney can deteriorate and crack, allowing water to seep in. Water damage can resut in significant structural damage to your chimney. It is vital to address any leaks or cracks as soon as possible.


  1. Blockages: Debris, such as leaves and twigs, can accumulate inside your chimney and block the airflow. Blocked chimneys can cause smoke and carbon monoxide to back up into your home, which can be extremely dangerous.


Different Types of Chimneys


Chimneys come in many different shapes, sizes, and styles. Each type of chimney has its unique benefits and drawback:


  • Masonry chimneys are the most common type made from brick and mortar. They work well in older homes and provide a traditional look. However, they require regular maintenance and can be expensive to repair or replace.


  • Prefabricated chimneys are prefabricated metal chimneys installed on the home’s exterior. They are easier and less costly to install, but they can be noisy and may not fit the home’s exterior.


  • Wood-burning chimneys are designed to be used with wood-burning stoves and fireplaces. They are highly efficient and require little maintenance, but they can be hard to install and need regular cleaning.


  • Finally, gas chimneys are designed to be used with gas-burning appliances. They are less efficient than wood-burning chimneys but require less maintenance and are easier to install.


No matter which type of chimney you choose, keeping it in good condition is important. Regular inspections and maintenance are essential for ensuring your chimney is safe and working properly.




Chimney maintenance is an integral aspect of homeownership that should not be overlooked. Regular chimney maintenance can help to prevent potential hazards and improve the efficiency of your heating system. If you encounter any chimney-related problems, it is essential to seek professional help from a reputable chimney repair service. There are several chimney repair services in Toronto, and you must ensure you’re working with a reliable one.

chimney removal in Toronto

Chimneys are essential to a home’s heating system, but sometimes, they become more of a liability than an asset. If you’re considering removing a chimney, you must be aware of the essential things to consider before starting. In this article, we’ll discuss what you should think about before removing a chimney so that you can make an informed decision.


The Purpose of a Chimney


A chimney is a vertical structure that provides ventilation for heat and smoke produced by a fireplace, stove, or furnace. Its primary function is to remove smoke and other harmful gases resulting from combustion. Chimneys also prevent heat damage to the roof and other parts of the house by directing hot air out of the home. 


Reasons to Remove a Chimney 


You may want to remove a chimney from your home for several reasons. For example, create more space in your home or improve its aesthetic appeal. Here are some of the most common reasons why people remove chimneys:


  1. Unused


An unused chimney can be a waste of valuable space in your home, but it can also pose a potential fire hazard if not maintained properly. Removing it provides more space, eliminates the risk of fire, and improves your home’s overall safety.


  1. Damage


Chimneys that are not regularly maintained can become damaged over time, putting your home at risk. If your chimney is in disrepair and poses a safety risk, removing it can be the best option to prevent further damage and ensure your home’s safety.


  1. Aesthetic


They can be an eyesore and detract from your home’s overall appearance. If you’re unhappy with the way your chimney looks, removing it can instantly improve your home’s curb appeal. You’ll be able to enjoy a more cohesive and attractive exterior that enhances your home’s overall value.


  1. Renovations


If you’re planning to renovate your home, removing a chimney can create more space and make the renovation process easier. Removing it can also open up a room and provide more natural light, making it feel larger and more inviting.


  1. Cost


Maintaining a chimney can be costly, especially if it requires frequent repairs. Removing it can eliminate the ongoing maintenance costs associated with it. Additionally, if you’re not using your chimney, you may be wasting energy and money by heating an area that you don’t need to. Removing it can improve your home’s energy efficiency and save money on your energy bills.




Removing a chimney can be an effective way to improve your home’s aesthetics and create more space, but it’s not a decision to take lightly. Before you begin the process, you need to consider several factors, such as the chimney’s structural role, building codes, heating system, roofing, and cost. By taking the time to evaluate these and other essential aspects, you can make an informed decision and ensure that the work is done correctly. If you need clarification about removing a chimney or have any questions, consult a professional contractor or a building inspector.

When it comes to maintaining the safety of your home, there’s no job more important than waterproofing your chimney. Waterproofing your chimney will protect against water damage and ensure the structure remains safe and intact for years. 


With the right supplies and a bit of DIY know-how, waterproofing your chimney is easy and can be accomplished in a few simple steps. This article will walk you through the process and provide tips for getting the job done right.


The Right Waterproofing Product


Before investing in a waterproofing product, you should be aware that the lower the price, the less effective the protection it will provide. One well-known brand is not expensive, but its performance is limited as it will lose its effectiveness when exposed to UV rays from the sun.


If you’re looking for a product to protect your masonry, poly siloxanes or silanes are a great choice. These products don’t use solids to fill up the pores of the masonry but instead create an electrostatic charge that water can’t penetrate. 


This ensures that any moisture already present in the masonry can escape, preventing any new water from entering. These products can be a bit more expensive, but they are well worth the investment.


Sealing Brick Chimney


Let’s begin with the fact that nearly all people reading this own a brick chimney. The key to waterproofing is the permeability of the material being protected, because you don’t waterproof materials that don’t let water through, such as steel or vinyl. 


Compared to other materials, like cinder blocks, bricks are usually less porous. Still, there is variation in the porosity of the brick itself.


When waterproofing a chimney, it is important to take extra precautions to ensure it is properly done. Doing the job twice is the best way to ensure the job is done correctly. 


It may cost more, but it is worth it. If the job needs to be done a second time, don’t be too hard on the contractor, as it can happen to anyone. Special attention should be paid when getting the job done again.


How Long Does Chimney Waterproofing Last


The length of time that chimney waterproofing lasts depends on a few factors. The first is the type of material used for the waterproofing. Some materials, such as asphalt-based sealants, can last up to 10 years. Other materials, such as elastomeric coatings, can last even longer. The second factor is the quality of the workmanship. Poorly applied waterproofing can be ineffective and need to be redone much sooner.


The third factor is the environment in which the chimney is located. The waterproofing may not last as long if the chimney is in a very wet or humid area. In addition, if the chimney is exposed to a lot of direct sunlight, the waterproofing may degrade faster.


Finally, the amount of maintenance done to the chimney can affect the lifespan of the waterproofing. The waterproofing may last longer if the chimney is regularly inspected and maintained. Regular inspections will also help to identify any problems before they become too severe.


The Bottomline


Waterproofing a chimney is an important step in protecting the structural integrity of your home. It is relatively easy and requires only a few basic tools and materials. 


Following the steps outlined in this article, any homeowner can successfully waterproof their chimney and ensure their home is protected against water damage. With regular maintenance, waterproofing your chimney can help you prevent costly repairs in the future.

chimney repair services in Toronto

Are chimney cracks bad? This is a question many homeowners ask when they notice cracks in their chimneys. Cracks may seem like a minor issue, but they can actually be a sign of serious damage. It is important to understand the potential risks associated with cracked chimneys so that you can take steps to protect your home and your family.


What Are the Risks Associated With Cracked Chimneys?


A cracked chimney is a nuisance and can pose a hazard. It can be a major source of heat loss and a potential fire risk. This article will discuss the risks associated with a cracked chimney and the best ways to repair it. But first, our experts in chimney repair in Toronto share some of the signs you need to watch out for:


Signs of a Cracked Chimney


There are several signs indicating a cracked chimney. Most noticeable is a visible crack on the exterior of the chimney. Other signs of a crack can include deterioration of the mortar or bricks, pieces crumbling away, and water leakage. If the smell of smoke comes from the chimney, it could be a sign that the flue liner has cracked.


Risks of Having a Cracked Chimney


There are several risks associated with having a cracked chimney, including fire, health, and property damage.


Fire Risk


A potential fire hazard is the most serious risk associated with a cracked chimney. If a crack lets in sufficient amounts of air, then a fire can start and spread quickly. If the crack is in the flue liner, it can cause an accumulation that can block the chimney and prevent smoke and gas from escaping. This can cause an explosion inside the chimney, resulting in a fire.


Health Risks


A cracked chimney can also let in toxic gases, such as carbon monoxide, into the home, which can be fatal if not properly addressed. This is especially true in buildings with poor ventilation or closed flue systems, such as some older homes. If the chimney is not sealed properly, it can also cause a buildup of condensation, resulting in mold and mildew growth.


Property Damage


A cracked chimney can also result in additional property damage. A cracked chimney can cause water to leak into the home, damaging walls and ceilings. The accumulation of water and condensation can also create structural damage to the chimney itself, resulting in the need for costly repairs.


Best Ways to Repair a Cracked Chimney


The first step in repairing a cracked chimney is to identify the source of the crack. This can be done by looking at the exterior of the chimney and noting any signs of damage. It’s also important to inspect the inside of the chimney for any signs of cracking or other damage. If the source of the crack is not immediately apparent, it’s best to contact a professional for further inspection.


Once the source of the crack is identified, the next step is to repair it. For minor cracks, this may involve applying a sealant to the crack and then covering it with a chimney cap. For more significant cracks, it may be necessary to replace the chimney liner or the entire chimney.


In addition to repairing the crack itself, it’s important to address any other damage that the crack may have caused. This may involve replacing broken bricks and mortar or even replacing the entire chimney if extensive damage has occurred.


Finally, it’s important to take preventative measures to ensure that the chimney remains in good condition. This may involve regular inspections and maintenance and installing a chimney cap to help prevent water and debris from entering the chimney.




A cracked chimney can be a major hazard and result in extensive property damage and health risks. Inspecting the chimney regularly and addressing any cracks or signs of damage as soon as possible is important. The best way to address a cracked chimney is by contacting a professional who can properly assess the damage and provide you with the necessary chimney repair services.

chimney rebuild in Toronto

Chimneys are an important part of a home, providing ventilation for various appliances and heating systems. However, over time, chimneys can become damaged and require repairs. Knowing the signs of a chimney that needs to be rebuilt can help ensure your home is safe and functioning properly. In this blog post, we’ll discuss eight signs of needing a chimney rebuild.


  1. Cracks and Leaks


If you notice any cracks or leaks in your chimney, this is a sure sign you need to rebuild it. Cracks can create openings for cold air to enter your home and an entry point for water or pests. If you notice any cracks or leaks, contact a professional to assess the damage and determine if a rebuild is necessary.


  1. Deteriorating Mortar


The mortar used to hold together the bricks of a chimney can deteriorate over time, allowing water to enter and cause further damage. If you notice any crumbling or missing mortar, it’s important to have it repaired as soon as possible.


  1. Rusting Flashing


Flashing is the metal strip that is used to seal the space where the chimney meets the roof. If the flashing is rusted or corroded, it must be replaced as soon as possible to prevent water damage to your home.


  1. Loose Bricks


If you notice any loose bricks in your chimney, it may be a sign that it needs to be rebuilt. Loose bricks can create openings for cold air to enter, as well as an entry point for pests.


  1. Soot Buildup


Soot is a byproduct of burning wood or other fuels. If you notice a buildup of soot in your chimney, it’s a sign that it needs to be cleaned. If the soot buildup is too severe, it may require a rebuild.


  1. Leaning Chimney


If your chimney is leaning, this is a sign of structural damage and likely means a rebuild is necessary. A leaning chimney can cause the entire structure to fail, so it’s important to take this seriously and consult a professional. 


  1. Missing Chimney Cap


The danger of having no chimney cap is that it can contribute to the deterioration of the chimney. With no cap, rain and other moisture can enter the chimney and cause the masonry to degrade. This can lead to cracks and other damage, which can cause smoke and other gases to enter the home. 


  1. Spalling


Spalling can occur due to exposure to extreme temperatures, water damage, and the normal wear and tear of aging. If the spalling is left untreated, it can lead to further damage and even structural failure.


Signs of spalling can include crumbling bricks, flaking mortar, and pieces of the chimney coming off. If you notice any of these signs, it is important to have a professional inspect your chimney. They can determine the extent of the damage and recommend the necessary repair. It is also important to ensure that your chimney is properly sealed and waterproofed to prevent further damage.




If you notice any of the signs listed above, it is important to act quickly and hire a professional to assess the condition of your chimney.  A chimney rebuild is necessary when the structure is damaged and should not be delayed.  A professional chimney technician is best equipped to determine the extent of the damage and recommend the best course of action for your chimney.  Taking these steps now can save you time, money, and headaches down the road.

waterproofing services in Scarborough

Chimneys are prone to damage from harsh weather conditions like rain, snow, and sleet, and these elements can cause the materials used in the construction of the chimney to break down more quickly. Waterproofing the chimney can help it to last much longer and prevent costly repairs in the future.


Unfortunately, many people doubt the need and purpose of a waterproof chimney. Let us clear up some of these common misconceptions. Read on.


“Chimney Caps Are Useless”


Chimney caps act as rain hats for chimneys, protecting against rain and other elements to help prevent water damage to the chimney. Without a chimney cap, water can easily seep into the chimney’s bricks and cause damage. To best protect a chimney from water damage, it should be fitted with a stainless or copper chimney cap, a sealed top crown, a vapour-permeable waterproofing application, and proper flashing.


“Chimney Exteriors Are Enough Indicator of Condition”


Waterproofing is essential to protecting your chimney from moisture. If the exterior looks good, waterproofing can ensure it stays that way. However, you may have noticed some white spots or moss. Moss can grow wherever water collects and takes root. 


Even if there is no visible efflorescence or moss, water can still find its way through the smallest cracks. As the water damage increases, the damage to the chimney grows. Waterproofing is key to preventing this kind of interior damage and preserving the good exterior look of your chimney.


“Chimney Liners Do Not Need to Be Maintained”


Homeowners need to take proper care of their appliances and their chimney liners to protect the masonry structure of the chimney. Having a properly fitted and adequately ventilated chimney liner is essential to preventing water from corroding and deteriorating the masonry bricks. Without a liner, the moisture from the elements of combustion will damage the inside of the chimney walls, leading to structural damage.


“Chimneys Can Last for Years Without Waterproofing”


Bricks are a solid material used in construction, but if not correctly maintained, weather can damage them over time. If the chimney is older than 10 years, it is likely already showing signs of water damage that can’t be seen from the ground. Tiny cracks will form, allowing water to enter and expand when it freezes. 


Almost all masonry chimneys have some cracks at the top. It is best to spend a bit of money now to prevent further damage rather than wait until the damage is visible from the ground and requires a more costly reconstruction.


“Chimneys Made of Brick Don’t Need to Be Waterproofed”


Bricks are not completely watertight, so it is vital to use a product that is made for masonry to make sure the brick is appropriately protected. If possible, look for a special water repellent that prevents water from entering the brick while still allowing the brick to breathe. This repellent is highly effective at reducing water penetration, making it an ideal choice for homes with brick or masonry chimneys.


Final Thoughts 


Waterproofing your chimney can be an effective way to prevent water from entering your home. There are several different methods for waterproofing chimneys, such as using a sealant or a repellent or adding a waterproofing membrane. 


By waterproofing your chimney, you can protect your home from water damage and reduce the risk of mould and mildew growth. Properly waterproofing your chimney is an essential aspect of home maintenance that should not be overlooked.
