West Nyack is Clarkstown suburb through and through: 1950s and 1960s splits and ranches around Strawtown Road and Western Highway, larger colonials from the 1970s and 1980s on the wooded lots toward Bardonia and Blauvelt, and a few older farmhouses on the roads that predate the Thruway. Like the rest of Clarkstown, its chimneys are mostly masonry with clay-tile flues venting both a fireplace and the heating plant, and most of those heating plants have been changed at least once since the house was built.
West Nyack's lots are wooded and low-lying in places, so shade, damp and leaf litter are constant; a cap with a screen keeps the flue clear, and the crown and flashing are where leaks start. Fireplace use is common enough that fall sweeps book early. For houses that have converted to gas in the past decade without relining, the heating flue is the one most likely to fail a camera inspection.
West Nyack is unincorporated, in the Town of Clarkstown; the Clarkstown Building Department handles permits for relining and rebuilds, and every contractor needs the Rockland County home improvement license.

West Nyack questions
What does chimney repair cost in West Nyack?
Same published 2026 national ranges as the rest of the county: common repairs $200 to $850, flashing to $1,800, liners $900 to $3,800, rebuilds $1,500 to $15,000 (HomeGuide, Angi). Two-story colonials with tall stacks land in the upper half.
Can I use the fireplace if the furnace shares the chimney?
If each appliance has its own flue inside the chimney, yes; most masonry chimneys built here have separate flues. A Level 2 inspection confirms the flues are separate, intact and correctly sized.
Where do permits go?
Town of Clarkstown Building Department in New City.
