PlymouthHome base, in all its variety: fieldstone antiques in Chiltonville that leak soil gas from every joint, postwar ranches in North and West Plymouth over poured slabs, coastal capes in Manomet and Cedarville with crawlspace additions, and slab-on-grade newer homes in The Pinehills where the living space sits directly on the soil. Each foundation type gets a different mitigation design, and we've built systems on all of them. If it sits on Plymouth ground, we've tested its cousin.
KingstonColonials near the center, newer subdivisions toward the bay. Nearly 1 in 4 Kingston tests come back at or above the action level, per state data. Kingston's steady real estate turnover makes it a transaction-testing regular: monitors placed inside inspection windows weekly, results your attorney can use.
DuxburyHigh-value sales where a surprise 6.0 can rattle a seven-figure closing and every day of delay costs someone money. Priority monitor placement, 48-hour reporting, and fast post-mitigation retests keep Duxbury deals on schedule. Sellers here increasingly pre-test before listing for exactly that reason.
CarverWell country, and the town where both radon pathways show up on the same property most often: soil gas in the basement, dissolved radon in the well water, each needing its own fix. If you're on a Carver well and you've only ever tested your air, you've seen half your picture.
Plympton & HalifaxRural lots and private wells, where the question is less about basement air and more about what's dissolved in the well water. Air and water tests together give the full picture here.
Marshfield & PembrokeSouth Shore capes and split-levels where the finished basement is the family room, the home office, or a teenager's bedroom, which makes the lowest-level number the one that actually matters. Testing here is less about the deed and more about who sleeps downstairs.
Middleborough & WarehamThe southern edge of the regular route, same geology, same service. Near the county but not on this list? Call and ask: if we can serve you properly we'll say yes, and if someone closer serves you better, we'll say that instead, because the fastest way to be trusted in a small county is to deserve it.
