Before you hire in Greenwood Township

Pre-war construction

25% of homes predate 1940. Expect plaster walls, balloon framing and possible asbestos in old pipe wrap or floor tile; test before demolition with a licensed asbestos contractor.

Mid-century and newer systems

Most homes here date from 1990 or later. Original furnaces, water heaters and roofs from that era are well past their service life, so replacement planning matters more than repair.

Permits: check with the Greenwood Township building department before work starts.
