You can't see it, smell it, or taste it, but Bristol County's tests come back above the EPA action level more often than almost anywhere in Massachusetts. We test your home, install the fix, and retest to prove the number dropped.
Taunton sits in EPA Radon Zone 2, and the state's own data tells the local story plainly: across Bristol County, more than 1 in 4 radon tests from the last decade came back at or above the EPA action level of 4.0 pCi/L. In Taunton itself it's roughly 1 in 5, with nearly half of all tests at or above 2.0. And the single highest reading in the entire state dataset was recorded right here: 837.1 pCi/L, more than 200 times the action level. The EPA's guidance is blunt: all homes should be tested, regardless of zone.
Here's the part that should get your attention: almost nobody in Taunton has checked. The state logs a testing rate of about 63 per 1,000 housing units here, meaning fewer than 1 in 15 homes has ever run a radon test. In a county where a quarter of the tests that DO happen come back high, the untested house isn't the safe one. It's just the unmeasured one.
The good news: radon is fixable. A properly installed system typically pulls levels below 2.0 within a day and runs on about as much electricity as a light bulb.
Sub-slab depressurization sized to your foundation: sealed suction point, quiet inline fan, vent above the roofline, and a retest that proves the number dropped.

Written results for your records or your attorney.
Taunton's housing stock is old, and old houses breathe soil gas. The Silver City's pre-1940 two-families and mill-era homes in Weir Village and Whittenton sit on fieldstone and first-generation poured foundations with a century of settling cracks. East Taunton and the Route 44 corridor add postwar ranches and newer slab construction that route radon differently than anything with a full basement. And step into the ring towns, Rehoboth, Berkley, Dighton, Lakeville, and private wells add a second pathway entirely: radon dissolved in groundwater, released into your air with every hot shower.
A crew that works these foundations weekly designs the right system the first time; a call-center franchise quoting from another state does not.
Nobody puts prices on these sites, so here are the honest ranges most companies hide. Every job gets a written quote before work starts.
| Job | Typical range |
|---|---|
| Radon Mitigation System Installation | $1,200 – $2,500 |
| Radon Testing | $175 – $275 |
| Real Estate Radon Testing | $200 – $300 |
| Radon in Well Water Treatment | $3,000 – $6,500 |
| New Construction Radon Systems | $400 – $900 |
| Radon System Repair & Fan Replacement | $350 – $700 |
What moves the price: foundation type, footprint size, whether the run is interior or exterior, and how far below 4.0 you're starting from.
The data says yes: more than a quarter of Bristol County radon tests from the last decade came back at or above the 4.0 action level, per state DPH data, and the highest reading ever logged in the state dataset came from Taunton. But averages describe counties, not addresses. The only way to know your house is a test.
The EPA recommends fixing your home at 4.0 pCi/L or higher and considering it between 2.0 and 4.0. Radon is the second leading cause of lung cancer after smoking. There's no "safe" level, but below 2.0 is the practical target.
Most single-family systems run $1,200 to $2,500 installed. Full pricing on our mitigation page.
Levels typically drop within 24 hours of the fan switching on.
Smart sellers do. Test now and you control the timeline and contractor; let the buyer's inspector find it first and you're negotiating under deadline pressure.
The opposite. A documented system with a passing retest is a selling point: one less contingency for a buyer to raise.
