Chimney sweeping in New Windsor

The Town of New Windsor sits directly north of Cornwall in Orange County. It is a town with no village inside it, so permits come from the town building department.

The housing is newer than in the river villages. Census estimates put the median home in the town as built in the late 1970s. Only about one in twenty dates from before 1940, and about a quarter was built in 2000 or later. Roughly a fifth of homes are in larger multi-unit buildings.

More heating flues than fireplaces

Newer houses tend to have a chimney that serves a furnace, boiler or water heater. Unlike a fireplace, nobody looks at a furnace flue. It sits behind the appliance in a basement or utility room and runs every day for half the year.

Flue sizing after a furnace replacement. A new high-efficiency furnace or boiler sends much less heat up the flue than the unit it replaced. The flue that suited the old appliance is now too large. Flue gases slow down, cool and condense on the way up. That condensate is acidic. It attacks the mortar joints between clay tiles from the inside, where nothing shows until the damage is significant.

Orphaned water heaters. When a furnace is upgraded to a direct-vent unit, the gas water heater is often left venting into the chimney alone. The flue is then far oversized for one small appliance.

Fuel conversions. Changing from oil to gas changes flue gas temperature and chemistry. It is one of the triggers for a Level 2 inspection.

Factory-built fireplaces and town rules

Homes from the 1970s onward often have a factory-built fireplace with a metal chimney in place of a masonry one. These are swept too, with brushes sized to the metal flue. They are also checked against the maker's listing, because the fireplace and its chimney are tested as one system.

The town code requires a building permit to install a solid-fuel appliance, chimney or flue. It also prohibits new outdoor wood furnaces across the town.
