SWAT Radon Mitigation

SWAT Radon Mitigation, out of Maynard, installs the fan-and-piping systems homeowners need after a radon test comes back high. The number reviewers keep coming back to is how fast it works: one customer watched a post-install reading fall from a range of 8-12 down to 1.5 within a day, then under 1 the day after; another saw a reading above 10 drop to 0.3 in 24 hours. Recent reviews describe a similar shape of visit across a rotating cast of technicians -- Jon, Josh, Ken, Rob, Chris, Connor, William, Al, David, Andrew -- walked through where the piping would run, worked in two to three hours, and left the space clean. On Google, SWAT holds 4.9 stars across 129 ratings, and the written history behind that runs to 106 reviews across 2025 and 2026, with 50 of them in just the last six months. A Reddit commenter in a 2025 Boston thread said SWAT got their job done for roughly $1,800 against a $3,000 quote elsewhere -- one comment, but it lines up with what several Google reviewers say about being quoted less than competitors. The visits that go wrong describe a different company. A June 2026 review says the technician spent time arguing on the phone about where to put the system, got visibly frustrated, cursed, and left without a resolution. A July 2026 review says an installer left a job unfinished. Another, from July 2026, describes a retest that came back worse than expected and a $250 fee quoted just to send someone back out to look at it. Two older reviews -- one from January 2026, one from November 2025 -- describe a company that stopped answering the phone once a customer had a follow-up question, in one case over a threatened lien for an unpaid balance. SWAT is a reasonable call for a fast, inexpensive fix to a failed radon test, and most of the record backs that up. Before booking, it's worth asking directly what happens if the retest doesn't hit target, what a return visit costs, and who to call if it comes to that.
