Westford's mix of ledge and glacial till soil is consistent with the higher radon potential seen across this region, and basement or crawlspace homes here are frequently recommended for mitigation after testing.
Westford's larger-lot, lower-density character, about 712 residents per square mile across 30.6 square miles, is typical of the towns in Middlesex County's EPA Zone 1 radon designation, where testing every level of the home is the only reliable way to rule out elevated radon.
Whether you're testing for the first time, responding to a home inspection result, or ready to install a mitigation system, getting matched with the right local contractor is the first step.
How Radon Testing & Mitigation Works
1. Radon Testing
A test device is placed in the lowest livable level of the home for at least 48 hours to measure radon gas concentration in picocuries per liter (pCi/L).
2. Understanding the Result
The EPA recommends mitigation at or above 4.0 pCi/L, and suggests considering it between 2 and 4 pCi/L. There is no known safe level, only degrees of risk.
3. System Design
Mitigation contractors design a system based on foundation type — basement, crawlspace, or slab — most commonly a sub-slab depressurization system.
4. Installation
A PVC pipe is routed from beneath the foundation up through the home and out above the roofline, with an in-line fan drawing gas out and venting it safely outside. Most installations take about a day.
5. Post-Installation Testing
A follow-up test confirms the system has brought radon levels down, typically well below the 4.0 pCi/L action level.
6. Ongoing Monitoring
Retesting every two years, and after any major renovation or foundation work, is recommended since radon levels can change over time.

Common Questions
Is radon really a serious health risk?
Yes. The EPA and U.S. Surgeon General identify radon as the second leading cause of lung cancer in the United States after smoking, responsible for an estimated 21,000 deaths per year nationally.
Why is radon so common in Massachusetts?
Much of Middlesex County sits on granite bedrock and glacial soil deposits, both associated with higher radon potential. Testing is the only way to know your home's actual level — it varies significantly even between neighboring houses.
How much does mitigation typically cost?
Most residential systems run $800–$2,500 installed, depending on foundation type, size, and system complexity.
How long does installation take?
Most single-system installations are completed in about a day.
