Chimney Leak Repair & Waterproofing

That stain on the ceiling near the fireplace? Nine times out of ten it’s not the roof — it’s the chimney: flashing that’s lifted, a cracked crown, a missing cap, or brick that’s begun drinking water.

How we stop leaks

  • Flashing — re-seat, re-seal or re-fabricate the roof-to-chimney metalwork
  • Crown — seal minor cracking or recast with a proper drip edge
  • Masonry — breathable siloxane waterproofing that repels rain but lets brick breathe (never paint or film sealers, which trap moisture and make spalling worse)
The cost of waiting: Water compounds: framing, insulation, then mold. The source is usually a $-hundreds fix — the delay is what costs $-thousands.

One visit, photos of the cause, and a fix priced in writing.

FAQs

Can I just paint the chimney to seal it?

Please don’t — paint traps moisture inside the brick and accelerates freeze-thaw damage. Breathable treatments are the right tool.

How long does waterproofing last?

Roughly a decade per application, applied after any needed repairs.
