Introduction: Why Radon Matters in New England
Radon is an invisible, odorless radioactive gas that can accumulate in homes, especially in New England. In towns like Exeter, Kingston, Hampton, Dover, Stratham, Portsmouth, and Brentwood, older homes built on stone foundations or with basements are particularly susceptible.
Radon is the second leading cause of lung cancer after smoking, and high levels are commonly found in basements, where gas seeps in through foundation cracks, footing-wall joints, and under-slab areas. Detecting and mitigating radon is essential for both health and safety.
Why New England Homes Are at Risk
Several factors make New England homes more vulnerable:
- Older foundations: Stone and block walls often have small gaps that allow radon to enter.
- High water tables and frost heaves: Seasonal soil shifts create cracks or gaps around the footing-wall joint.
- Basement living spaces: Finished or semi-finished basements increase exposure risk.
- Local geology: Certain soils in NH and surrounding areas naturally emit more radon gas.
Homes in Plaistow, Seabrook, North Hampton, Amesbury (MA), and Haverhill (MA) often show elevated radon levels due to these factors.
Signs You May Need Radon Mitigation
Radon gas is invisible, so testing is the only reliable way to know your risk. Professional mitigation is recommended if tests show:
- Levels above 4.0 pCi/L (EPA action level).
- Homes with basements or crawl spaces built over stone or block foundations.
- Older homes experiencing seasonal foundation shifts.
Professional Radon Mitigation Methods
Mitigation is not a DIY project โ proper installation requires trained professionals who understand New England soil, home construction, and venting techniques. Common methods include:
- Sub-Slab Suction Systems
- A pipe is installed beneath the concrete slab to draw radon gas from under the foundation.
- A vent fan safely expels the gas above the roofline.
- Suction prevents radon from entering living spaces.
- Drainage-Compatible or Vapor-Sealed Waterproofing
- If your basement is being waterproofed, radon-safe methods ensure water management systems do not interfere with radon airflow.
- Can include sealed vapor barriers or radon-compatible drainage channels, protecting both basement dryness and air quality.
- Crawl Space Ventilation
- In homes with crawl spaces, proper ventilation or sub-membrane suction systems can reduce radon accumulation.
Why Professional Installation Is Critical
Improper mitigation can lead to:
- Radon venting back into the basement instead of outside.
- Reduced system efficiency due to blocked or poorly placed suction points.
- Interference with existing waterproofing or sump pump systems.
- Non-compliance with local building codes.
Professionals ensure that radon is safely vented, basement waterproofing remains effective, and all systems operate together without compromise.
New England Homes Require Expertise
In towns like Exeter, Kingston, Hampton, Dover, Stratham, Portsmouth, Plaistow, Seabrook, Brentwood, and Haverhill (MA), seasonal soil movement, frost heaves, and older foundations make radon mitigation more complex than in other regions. Professional evaluation guarantees proper system placement and long-term performance.
