Find the Source Before You Seal
Stains on ceilings or above mantels often trace back to multiple points—not just one. Our technicians perform a methodical leak inspection, beginning at the cap and crown, then moving down the stack to check flue tile joints, mortar, brick faces, and flashing where the chimney meets the roof. We look for hairline crown fractures, loose step flashing, open mortar joints, porous masonry, and missing caps or screens that invite direct rain entry.
When needed, we use moisture meters and staged water testing to confirm the path of entry. You’ll get photo documentation and a prioritized plan: stop active water first, then add long-term protection so the chimney stays dry through Stamford’s freeze–thaw cycles.
Common Leak Sources in Stamford
- Cracked or undersloped crown: Allows water to pool and drive into the flue tile joint.
- Missing or damaged cap: Direct rain entry, animals, and debris clogging the flue.
- Failed flashing: Gaps at the roof-to-chimney seam from wind or thermal movement.
- Open mortar joints / spalling brick: Porous, weathered masonry absorbs and transports water.
- Absorbent brick faces: Untreated masonry wicks moisture that later appears as interior staining.
- Chimney sidewall/shoulder transitions: Poor detailing at step-backs or decorative shoulders.
Each source needs the right fix. We don’t “caulk and hope.” We repair correctly and add breathable protection so the structure can dry out rather than trap moisture.
