At Above Roofing, we’re not just “a different breed of roofer”— we’re your go-to experts for everything that covers and protects your home. We understand the critical role your chimney plays, both aesthetically and functionally, in keeping your home dry.
A well-maintained brick chimney doesn’t just ensure your home’s safety; it adds charm and increases your property value. However, exposure to harsh elements can deteriorate the masonry, leading to moisture infiltration and structural damage. Sealing your brick chimney can be an excellent preventive measure that prevents water from leaking into your home.
Why Seal a Brick Chimney?
Bricks are porous by nature, making them susceptible to water absorption. If water seeps in, it can cause a lot of issues, even structural instability in severe cases. Sealing the bricks can act as a protective layer, repelling water while allowing the bricks to breathe.
Water absorption in brick is a problem because here in Michigan with the freezing and thawing, the water expands and contracts, breaking up your mortar and brick.
The Risks of a Neglected Chimney
- Structural Damage: Water can weaken the masonry, causing cracks and eventual collapse.
- Leaks: Water can seep into the interior of your home, causing damage to walls and ceilings.
When to Seal Your Chimney
Timing matters. It’s generally advisable to seal a new brick chimney within the first year after construction. If your chimney is older, inspect it annually for signs of wear and tear, and consider re-sealing every five years.
Choosing the Right Sealant
A good sealant will protect against water penetration while allowing moisture to escape. Siloxane-based sealants are an excellent choice because they are breathable and long-lasting. For more information on sealants, visit Chimney Solutions’ blog on waterproofing your chimney.
Steps to Seal a Brick Chimney
Here’s our Hassle-Free Process to get the job done:
Preparation
1. Cleaning: The chimney must be free of dirt, debris, and efflorescence. You can use a wire brush and a specialized masonry cleaner.
2. Repair: Fill any cracks with mortar and allow it to cure fully.
3. Weather: Choose a dry day for the application; the sealant will not adhere properly if the bricks are wet.
Application:
1. Test: Always perform a small patch test to ensure compatibility.
2. Apply: Use a low-pressure sprayer or a roller to apply the sealant, ensuring even coverage.
3. Second Coat: After the first coat has dried, a second application ensures maximum protection.
Curing:
Allow the sealant to cure for at least 24 hours before exposing it to moisture.
Maintenance:
Regularly inspect your sealed chimney. A well-applied sealant will last up to five years, but annual inspections can help you identify any issues before they become significant problems.
