A leading cause of chimney leaks is cracks or damage to the chimney crown, which is the top of the chimney. The chimney crown was designed not to allow water to rest on the chimney, so when it becomes cracked, water is able to settle into the top of the chimney. Any of these issues can be repaired by one of our trained technicians with patching or repairing and further protected with the application of custom sealants, specifically designed for fireplace systems.
Mortar Joint Cracking
Mortar is porous, allowing it to absorb water. Over time and with the addition of freezing temperatures, water can expand in the mortar until the joints become cracked, often with chunks of mortar falling out completely.
