Radon Testing in Portsmouth, Rhode Island
Portsmouth covers the northern end of Aquidneck Island and includes the neighborhoods of Common Fence Point, Island Park, and Prudence Island (which is part of the town).
Why radon testing matters in Portsmouth
Portsmouth's spread of shoreline homes, inland subdivisions, and small-island properties on Prudence sits on varied ground. Individual home testing is what tells you where a specific property falls.
Prudence Island properties, like other island homes, require additional scheduling around ferry access. Mainland Portsmouth homes are tested on standard timelines.
