Radon and New Berlin homes

New Berlin, on the east side of Waukesha County, was farm country until it became a city in 1959. Most of its developed land is housing, much of it on large lots, and parts of the city still feel rural. Many homes are ranches and two-stories on full basements, often finished. Some on the city's more rural edges have well water, which is worth knowing because radon can also come from well water, though most radon in Wisconsin homes comes from the soil.

Finished basements and larger homes

If your basement is finished, ask where the contractor would place the suction point. A storage or mechanical room is common, with the pipe running up through the garage. Larger homes, or homes with an addition on its own slab, may need more than one suction point.
