How To Fix a Leaking Chimney 

None of the things that could damage your chimney are as destructive as water. Yes, water. Why? If your chimney leaks, it will let water seep into your chimney’s masonry and do extensive damage. The part of your chimney that extends above your roof faces a multitude of precipitation, including rain, hail, dew, and fog. Why does that matter? Because the bricks in your chimney are cooked by the sun on an almost daily basis, and as a result, they will become absorptive and suck up water much as a sponge does. If left alone, the leaks in your chimney could cause enough damage to crumble. 

Crumbling is not the only damage leaking chimneys can cause. It may also damage your roof and ceiling when they rot due to being saturated. Wetness in your fireplace and the surrounding ceiling will also promote mold and mildew growth in your attic and waterlogged walls. If you see blotches around the ceiling and walls near your fireplace, mold and mildew, have probably already taken hold. It may seem too late, but don’t worry; here is how to fix a leaking chimney.

Unmistakable Signs of a Chimney Leak

As we noted earlier, a leaking chimney can be unsafe and must be repaired before significant damage occurs. Here are some obvious signs of a leaking chimney:

• Water pooling in your fireplace’s firebox.
• Mold or mildew thriving on the exterior of your chimney.
• Splotches on the walls and ceiling near your fireplace.
• Loose or crumbling bricks in your fireplace (spalling).

You most likely have a leaky chimney if you notice any of these signs. It must be repaired immediately to prevent it from collapsing.

The Various Ways to Fix Your Leaking Chimney

Addressing Cracks in Your Chimney’s Crown

The concept of a chimney crown is very basic but effective. Your chimney’s crown is a hunk of cement at its very top. It envelops the area surrounding your chimney’s flue. Comparable to how brick and stone can become cracked and split by repeated exposure to precipitation, so can your chimney’s crown. If your chimney’s crown has developed cracks, without question, water will seep inside and facilitate its breakdown during freeze-thaw cycles, widening the cracks. If cracks develop at the chimney’s peak, it will soak up more water than the bricks and stone that make up the rest of your chimney. We have knowledgeable, qualified chimney sweeps who can quickly repair cracks in your chimney’s crown and safeguard your home and fireplace against water damage.

Flashing and Chimney Leaks

A critical piece of your chimney’s structure is flashing. It protects your roof from moisture where it meets your chimney. It may be constructed from galvanized steel, aluminum copper, or PVC. Flashing is situated around your chimney to close gaps and prevent water from getting under the shingles. Water can permeate your roof and the chimney’s bricks if your chimney lacks flashing. Eliminating the leak between your chimney and roof is as straightforward as placing chimney flashing between them.

Chimney Liner Damage 

When a chimney liner is punctured, the consequences could be catastrophic. A punctured chimney liner will let dampness from your chimney’s bricks inside the flue, causing additional fissures that lead to leaks. A damaged chimney liner also presents further hazards, such as deadly fumes floating into your living room or causing a fire in the frame of your house. Installing a fresh chimney liner will correct the problem quickly.
