Before you hire for a bathroom remodel in Londonderry
Census estimates put the median build year in Londonderry at 1983; about 19% were built in 2000 or later. Many homes of this age still have their first kitchen or bathroom. Decide early whether you want to move fixtures, since that changes the permit and the scope. 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.
Rockingham County is in IECC climate zone 5A, a cool, humid climate, on the U.S. Department of Energy's county map. In a damp climate, a bathroom exhaust fan that vents outside (not into the attic) helps prevent mold. Cold winters make exterior walls matter. If walls are opened, ask whether insulation will be added before they are closed.
About 63% of homes in Londonderry are single-family houses, and about 84% of occupied homes are lived in by their owners.
Permits and licenses in Londonderry
Moving plumbing, adding electrical circuits or changing walls usually needs a permit; swapping fixtures in place usually does not.
