Lewiston residents who discover elevated radon levels during testing face a straightforward solution: professionally installed mitigation systems that reduce indoor concentrations by up to 99 percent. Northeast Radon Solutions designs and installs systems tailored to each home's foundation type, basement configuration, and soil conditions. The process begins with foundation crack sealing to prevent radon from entering through gaps in concrete slabs or block walls, a common issue in Lewiston's older mill-district housing stock.
After sealing entry points, a vent and fan system is installed to create negative pressure beneath the foundation. This draws radon from the soil before it enters living spaces and vents it safely above the roofline. The fan runs continuously, using minimal electricity, and operates quietly enough that most homeowners forget it's there. Systems are designed to handle Lewiston's freeze-thaw cycles, snow load, and humidity without requiring seasonal adjustments.
What's Included in a Complete Mitigation System
Each installation includes PVC piping routed from the sub-slab or crawlspace to an exterior discharge point, typically above the eaves. The fan is mounted either in the attic or on an exterior wall, depending on home layout and aesthetic preferences. A manometer is installed to provide visual confirmation that the system is maintaining proper suction. All electrical work is completed to code, and systems are tested post-installation to verify radon reduction.
Lewiston's housing ranges from century-old multi-family buildings to split-level ranches, and each requires a custom approach. Homes near the Androscoggin River or built on sloped lots may need additional suction points or upgraded fans to maintain consistent performance. All work is backed by a five-year warranty covering both parts and labor, giving homeowners confidence that the system will perform as designed.

Radon mitigation isn't optional when levels exceed EPA guidelines—it's a health necessity. Long-term exposure increases lung cancer risk, and mitigation systems provide the only proven method to reduce indoor radon concentrations consistently. Homes throughout Lewiston benefit from installation, especially those built before modern vapor barrier standards were adopted.
