Chimney Leaks

Water is your chimneys worst enemy. The chimney is constantly exposed to outdoor elements. Masonry chimneys are very porous and absorb large amounts of water that expands & contracts during the freeze and thaw cycles of the winter, causing mortar and bricks to crack. Overtime, the freeze & thaw cycle will escalate the severity of chimney leaks & increase the cost of fireplace chimney repairs.

Chimney Leaks are some of the most difficult leaks to diagnose. There are many reasons for chimney leaks. Even when an inspector sees an obvious reason for a leak, there can be several factors that contribute to the leak which are not obvious. To properly diagnose and treat a leaking chimney it takes experience, education and the highly trained technicians from Triangle Chimney Pros. The CSIA certified technicians at Triangle Chimney Pros have conquered every chimney leak challenge in the Triangle Region of North Carolina.

The Five Most Common Causes of Chimney Leaks

Chimney Cap

Having a chimney without a cap is like having a house without a roof.
Installing a cap will prevent water, leaves, animals, and other debris from entering your chimney. A chimney cap keeps sparks from leaving the chimney and igniting nearby combustibles. Without a cap, excessive rainwater can run down your chimney and weaken bricks and mortar as well as causing your damper or firebox to rust or deteriorate.

Chimney Crown

The crown is the cement slab at the very top of your chimney. It helps ensure that water runs off the top of your chimney instead of entering the chimney flue. Over time the crown will crack and deteriorate; this can lead to extensive water damage in your chimney. Depending on the severity of the crown, Triangle Chimney Pros can either repair or replace your crown.

Chimney Flashing

The flashing is the metal strip that joins the roof to the chimney. The job of your chimneys flashing is to provide a waterproof barrier that prevents water from running down the chimney. Old and faulty flashing allows water to seep into living spaces causing damage to ceilings, walls and rafters. A professional from Triangle Chimney Pros can properly inspect your flashing issue and recommend a safe solution.


At Triangle Chimney Pros, we provide chimney-waterproofing services. Your brick chimney is built with materials that absorb water.
Moisture infiltration weakens the structure of your chimney, rusting out metal, steel and cast iron parts. Additional risks include damage to the chimney flue, damper and the flashing. Triangle Chimney Pros recommends having your chimney waterproofed to prevent expensive masonry reconstruction and repairs.


Mortar joints in your brick chimney can crack and wear away over time due to wind, rain and freezing temperatures causing both water leakage and structural problems. If your chimney has visible cracks or deterioration, we recommend our tuck-pointing service to prevent damage leading to total rebuild.
