Congers sits between Rockland Lake State Park and the Lake DeForest reservoir, and a lot of its housing started as lake cottages that were winterized and expanded after the war, joined by ranches and splits built through the 1950s and 1960s along Lake Road and Route 9W. Winterized cottages carry the usual risks: short chimneys built for an occasional fireplace that now vent a furnace, or that were pressed into service for a wood stove, with no liner and little height. The mid-century houses have the county-standard clay-tile flues, now 60 to 70 years old, and most have been through an oil-to-gas conversion.
Damp is the local theme. Lots near the lakes and the reservoir stay humid and shaded, which keeps brick wet and makes efflorescence, spalling and rusted dampers common even on chimneys with a cap. A breathable water repellent on sound masonry pays for itself here, and a missing or undersized crown overhang is worth fixing before the next winter.
Congers is unincorporated, in the Town of Clarkstown; permits for relining and rebuilds go to the Clarkstown Building Department in New City. Every contractor needs the Rockland County home improvement license.

Congers questions
How much does chimney work cost in Congers?
Published 2026 national ranges: sweep $150 to $375, cap or crown work $200 to $850, flashing $300 to $1,800, stainless liner $900 to $3,800, rebuild $1,500 to $15,000 (HomeGuide, Angi). The shorter stacks on Congers ranches and cottages often land toward the lower half.
Why is my chimney always damp or white-stained?
Water is moving through the brick. Near the lakes the masonry rarely dries out; the fix is a sound crown with an overhang, a cap, repointing where needed, and then a vapor-permeable water repellent. Painting or sealing with a non-breathable product makes it worse.
Where do permits go?
The Town of Clarkstown Building Department, for relining and rebuilds. Your chimney company handles it.
