Chimneys in Washingtonville, NY.

Washingtonville, NY chimney repair — custom chase covers for prefab chimneys, crowns and caps for brick, and leak-proof flashing.

Why hire us for chimneys in Washingtonville?

Many homes in Washingtonville’s newer subdivisions have prefabricated chimneys — a metal flue inside a wood-framed chase covered with siding. When the metal chase cover on top rusts or dishes, water runs straight down into the framing. We custom-fabricate chase covers with a proper slope and drip edge, and replace rotted chase siding when needed. Older brick chimneys in the village get the traditional work: crowns, caps, repointing and new flashing. Either way, we find the leak source first instead of patching symptoms.

  • Rusted chase covers on prefab chimneys are replaced with custom-fabricated, sloped covers.

QUESTIONS

Common Chimneys questions in Washingtonville, NY

More questions? Call (845) 234-9871 or request an estimate — we don't believe in pressure sales.

My chimney is covered in siding — can it still leak?
Yes. Chimneys built as wood-framed chases have a metal cover on top that rusts over time. Water pools on it and leaks into the chase. A new custom chase cover is the fix.
How long does chimney repair take?
Crown, cap and flashing repairs are usually finished in a day. Rebuilds take longer depending on height and condition.
Why do chimneys leak?
Most chimney leaks come from a failed crown, cap, or counter-flashing — not the roof field itself. We fix the source instead of smearing tar on the problem.
Do I need a liner?
If flue tiles are cracked or the fireplace or appliance vent is unsafe, a stainless liner is often the right fix without rebuilding exterior brick.
