Professional radon testing in Portland, ME involves air sampling for 48-72 hours with results delivered within 24 hours to determine radon levels in your home and protect your family.

Radon testing uses specialized air sampling equipment placed in the lowest occupied level of your home for 48 to 72 hours to measure radon concentration.

The testing device remains undisturbed during the sampling period. Closed-house conditions help ensure accurate readings that reflect typical indoor air quality.

After collection, results become available within 24 hours. This quick turnaround helps you make informed decisions about mitigation if levels exceed EPA safety thresholds.

You should schedule radon testing when buying or selling a home, after major renovations, or every two years as a preventive health measure.

Real estate transactions often require radon testing as part of the inspection process. Many Portland, ME buyers request testing before closing to assess potential health risks.

Seasonal changes and home improvements can alter radon entry points. Testing after finishing a basement or changing heating systems gives you current data on indoor air safety.

If you're looking for comprehensive solutions, radon mitigation services in Portland can address elevated levels discovered during testing.

Test results measure radon in picocuries per liter, with levels at or above 4.0 pCi/L requiring mitigation to reduce health risks from long-term exposure.

The EPA recommends action if your test shows 4.0 pCi/L or higher. Even lower levels pose some risk, so many homeowners choose to mitigate when results fall between 2.0 and 4.0 pCi/L.

Understanding your numbers helps you decide next steps. A certified radon professional can explain what your specific reading means for your household.

Portland's mix of older homes with stone foundations and newer construction on granite ledge can create varied radon entry points and elevated indoor concentrations.

Many Portland properties sit on geological formations with naturally occurring uranium deposits. As uranium decays, radon gas rises through soil and enters homes through cracks and gaps in foundations.

Older homes may have more unsealed penetrations, while newer builds sometimes trap radon due to tighter construction. Both scenarios benefit from professional testing to establish a baseline.
