Flooring in Pennsylvania

Census estimates put the median build year in Pennsylvania at 1965; about 32% of homes were built before 1950. Vinyl floor tiles and adhesives from before the 1980s can contain asbestos. Do not sand or scrape an old floor until it has been tested. Federal EPA rules require firms that disturb painted surfaces in homes built before 1978 to follow lead-safe work practices. Ask whether the company is EPA lead-safe certified.

About 21% of Pennsylvania's counties are in climate zone 4A (mixed, humid), based on the U.S. Department of Energy's county map. Humidity makes wood floors swell and shrink. Ask how long the flooring will acclimate and whether concrete slabs get a moisture test. Check your own county's zone, since conditions differ across the state.

Replacing floor coverings usually does not need a permit, but repairing or replacing the subfloor or joists can. In Pennsylvania, building permits are issued by cities and counties, so the rules depend on where the home is. Ask the company who pulls the permit, and keep a copy of it.

Home improvement contractors must register with the Attorney General's office. Look the company up with the Office of Attorney General before you sign.
