Moisture
Chimney Leak Repair
Water showing up near a fireplace almost always starts above it. The trick is finding the real source — cap, crown, flashing, or masonry — rather than chasing the stain.
The stain is rarely the source
Water travels. A damp spot on the ceiling or a stain by the firebox may originate feet away, at the crown, the cap, a cracked joint, or the flashing where the chimney meets the roof. We trace the path back to where the water actually enters.
Common entry points
The usual suspects are a missing or damaged cap, a cracked crown, deteriorated mortar, and failed flashing. Sometimes it's more than one at once. We identify what's contributing and repair the source, not just the symptom.

Frequently asked questions
Why does my chimney only leak sometimes?
Leaks often depend on wind direction, rain intensity, or snowmelt, which is part of why the source can be tricky to pin down without a proper look.
Is a chimney leak a roofing problem?
Sometimes it's the flashing at the roof line; often it's the chimney itself. We focus on the chimney and its components rather than general roofing.
