Leaky Chimneys

When people think of problems that can occur with their chimneys, the first thought is usually creosote build-up that can cause excess smoke in the home or fire in the chimney. This is a simple fix: just be sure to have yearly inspections and cleanings by chimney sweeps certified by the Chimney Safety Institute of America, such as the professionals at Chim Cheroo Chimney Service. But damage can also occur because of something that people don’t usually consider: water.

Water: An Unlikely Culprit

According to CSIA, all masonry chimneys are susceptible to the weathering that occurs from being exposed to outdoor elements such as rain, snow, and sleet. And although the stone in stone chimneys aren’t as likely to be affected, the mortar that holds the stones together is. Not only does the water itself cause damage, but when that water seeps into the materials that hold the bricks together and then freezes, the expansion that takes place causes stress on those materials. This stress will cause cracks to form, and that can cause big problems for your fireplace use.

Flashing is the sheet metal that keeps the intersection between the chimney and the roof itself tight, and this is a likely spot for leaks to occur, especially if this was improperly installed in the first place. Even with proper installation, however, wear and tear over time can cause breakdowns, and leaking can occur. Again, the simplest solution is to stop leaks before they start by scheduling regular chimney inspections and repairs.

Why Is This A Bad Thing?

Water leaking into your chimney can cause serious problems for homeowners. When the mortar between bricks breaks down, it can cause exterior and interior damage to your chimney. CSIA  states that other negative effects can include rusted damper assembly, stained chimney exterior, deteriorated central heating system, stained ceiling and walls, and tilted or collapsed chimney structure – and that’s just a few of the problems that could occur.

How Can This Be Fixed?

Fortunately, there are solutions to the problem of water leaks in your chimney. Oftentimes, a cracked or missing chimney cap is the problem. The chimney cap is an important part of the make-up of your chimney, one that can not only keep precipitation out, but also living creatures that like to seek sanctuary in your chimney. Repointing, or repair of the deteriorating mortar joints, is a process that qualified chimney technicians such as those at Chim Cheroo Chimney Service can easily undertake. It may also be necessary to repair or replace the flashing. This will keep rain or snow melt from running down the chimney into living areas, which will prevent staining or rotting of interior surfaces.

Another way to ensure a leak-proof chimney is waterproofing. Your chimney professionals can coat your chimney with a water repellent substance. Using the proper waterproofing system prevents water molecules from entering the brick and mortar while allowing vapor produced by combustion to exit your masonry. Ask your chimney care professional about waterproofing your chimney.
