When dealing with potential radon exposure in Portland, homeowners need clear answers within days, not weeks. Northeast Radon Solutions delivers professional air sampling that runs for 48 to 72 hours, with laboratory results available within 24 hours of test completion. This timeline matters because radon levels fluctuate with weather patterns, foundation settling, and seasonal changes common along the southern Maine coast.
Portland's mix of older Victorian homes, post-war ranch construction, and newer builds all share one vulnerability: granite bedrock beneath the city that can emit radon gas. Testing equipment is placed in the lowest occupied level of the home, away from windows and exterior doors, to capture an accurate baseline reading. The process is non-invasive and requires no modification to the structure—just uninterrupted monitoring over the test period.
What Testing Results Tell You About Your Home
Test results are reported in picocuries per liter (pCi/L), and the EPA recommends mitigation if levels reach 4.0 pCi/L or higher. Portland homes built before foundation standards were updated in the early 2000s often test above this threshold, particularly in neighborhoods near Deering Oaks, the West End, and Munjoy Hill where older basements lack vapor barriers. Even homes testing below 4.0 pCi/L may benefit from retesting during winter months when homes are sealed and HVAC systems circulate air differently.
The testing report includes a lab-certified measurement, date and time stamps, and placement notes. If levels exceed recommended limits, the same data guides system design for mitigation. Homeowners receive a printed and digital copy, which is often required during real estate transactions or when refinancing properties in Cumberland County.
