Custom Radon Planning for a Mother-Daughter Suite in Windham, ME

Sarah S. in Windham, Maine wanted to address elevated radon levels in a home designed as a mother-daughter suite, where the layout created a few unique challenges for system design. Testing showed radon levels at 5.0 pCi/L, above the EPA recommended action level, making mitigation the right next step for improving indoor air quality.

During planning, we found that connecting both sides of the home into a single extraction layout would be difficult because a guest bedroom sat directly between the ideal extraction point locations. Rather than force a less effective design, the homeowner decided to move forward with mitigating one side of the property for now, with the ability to evaluate additional options later if needed.

Our team designed the system around the accessible side of the home to create an efficient and practical solution while respecting the existing layout and living spaces.

Every home presents different challenges, and sometimes the best solution is a phased approach that balances effectiveness, design limitations, and homeowner goals.
