Professional Chimney Leak Detection & Repair

In assessing leaky chimneys, we begin with a thorough inspection. Our certified chimney inspectors are experts at finding the source of a chimney leak and getting right to work to fix it correctly. Black Moose Chimney & Stove holds certifications with the Chimney Safety Institute of America, and we are proud members of the National Chimney Sweep Guild and the Northeast Association of Chimney & Hearth Professionals.

What Causes a Leaky Chimney?

If you operate your chimney without a chimney cap, water can easily get into the flue. Likewise, a damaged chimney cap is not able to do its job in protecting against water from rain or melting snow. Learn how we can repair and install chimney caps.

The cement crown that covers the bricks at the top of your chimney is prone to cracking over time. When cracks enlarge, water can infiltrate the bricks and drip down into the flue. Learn how we can rebuild chimney crowns and perform waterproofing for minor cracking

Chimney liners perform many important jobs, one of which is preventing excess condensation from accumulating within the interior bricks of the chimney. Eventually, this moisture will damage the bricks and create a serious leak issue. Learn how we can repair and install chimney liners.

Flashing is the material that seals off the gap where the roof of your home meets the chimney. Damaged flashing will allow water to run down into the home structure and cause damage to the chimney masonry as well as beams, rafters and wall boards. This can be a serious problem, especially if mold begins to grow. Learn how we can repair and install chimney flashing.

Cracks in the bricks and mortar of a chimney can happen from normal aging, house-settling, extreme temperatures and high winds. Water can get into these cracks and freeze, which causes it to expand and do further damage. Damaged chimney masonry can easily be the cause of a chimney leak, and it also can result in an unsafe operational environment. Learn how we can perform chimney rebuilding and expert brick repair.
