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.
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.
Radon Mitigation System Installation →48 to 96 hour continuous monitor or charcoal test with a written report. Know your number before you spend a dollar on anything else.
Radon Testing →Buying or selling in Greater Taunton? Closed-house protocol testing inside your inspection window, results in 48 hours, report your attorney can use.
Real Estate Radon Testing →On a well in Rehoboth, Berkley, or Dighton? Radon dissolves in groundwater and releases in your shower. Aeration systems strip it before it enters the house.
Radon in Well Water Treatment →Passive rough-ins and active systems for new builds and additions. Cheapest radon system you'll ever buy is the one installed before the slab pours.
New Construction Radon Systems →Radon fans die quietly after 5 to 10 years and the house fills back up. Manometer checks, fan swaps, and retests for systems any company installed.
Radon System Repair & Fan Replacement →A 48 to 96 hour test tells you your actual number. No guesswork, no sales pitch.
If you're over 4.0, you get a written price for a system designed for your specific foundation.
Most residential systems go in within a day: sealed suction point, PVC run, quiet fan, vent above the roofline.
Every install includes a post-mitigation retest: you pay for a number, not a promise.
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.
A real concern on private wells in Rehoboth, Berkley, and Dighton. See well water treatment.
Radon Mitigation for Taunton and Bristol County. Test it. Fix it. Prove it's fixed.
