Essential Maintenance Tips For Your Chimney Masonry

Posted on: 15 June 2023


If you're like most people who've purchased a home with a fireplace, you're undoubtedly looking forward to spending the evening in front of a blazing fire when the weather turns chilly. However, if you've never maintained a chimney before, you probably have some questions about best practices to ensure its longevity and functionality. Here's what you need to know about keeping your chimney in great shape: 

Regular Inspections Are Crucial 

Regular inspections by professional chimney contractors are the cornerstone of chimney maintenance. An annual review by a certified professional can help identify any problems before they escalate. This routine check examines the outer masonry for signs of deterioration such as cracks, loose bricks, or missing mortar. 

The inspection will also include the inner parts of your chimney. Problems like flue liner cracks or creosote buildup can pose severe safety risks, including house fires or carbon monoxide leaks. 

Timely Repairs Are Essential

When you notice any signs of damage to your chimney masonry, act quickly. Small cracks can turn into larger ones, especially during the winter, when water entering these cracks can freeze and expand. Loose or missing bricks and deteriorating mortar joints should be addressed promptly as well to prevent further structural damage.

Masonry repairs can range from simple repointing to complete rebuilds, depending on the damage extent. Repointing involves removing damaged mortar and replacing it with new, matching mortar. More extensive damage might necessitate a partial or complete rebuild of the chimney. A professional mason can guide you in the right direction for repairs.

Keeping It Clean

Cleanliness plays a pivotal role in maintaining your chimney. One critical aspect of cleanliness is keeping the chimney free of creosote, a dark, flammable substance that can build up in your chimney over time.

Regular cleaning or sweeping is necessary to remove creosote and other debris. Chimneys that service wood-burning appliances typically require more frequent cleaning, given the higher levels of creosote these fuels produce. Aim for at least an annual cleaning, but adjust based on your chimney's usage. If you live in a cold-climate area where fireplaces are used year-round, talk with your local chimney care professional about how often your chimney should be cleaned. 

Protect It From the Elements

Lastly, protect your chimney from weather-related damage. Consider using a chimney cap, a simple device that keeps out rain, snow, animals, and debris. Additionally, a good quality water repellent can help protect the masonry from water damage.
