Radon mitigation & testing in Manchester, NH

Older homes, multi-family and rentals in Manchester

Manchester has a large stock of older homes and multi-family buildings. That raises questions single-family guides don’t answer — like which units to test and who is responsible.

Multi-family buildings

Radon tends to be highest at the lowest levels, so ground-floor and garden-level units matter most. National certification bodies offer separate multi-family measurement and mitigation credentials (listed on the NRPP directory); for a building with several units, ask whether the professional holds them.

Landlords and tenants

If you own rental property, testing the lowest occupied units is a simple, inexpensive step. If you rent, the state’s free test kit lets you check your own unit. (NHDES)

Older foundations

Older stone or block foundations, dirt-floor sections, and many cracks can make a system harder to design. Expect a contractor to visit before quoting, and ask how they will seal openings and whether more than one suction point is needed. (EPA)

Water

Most of the city is on public water. If your property is on a private well, NHDES recommends testing the water for radon too. (NHDES)
