Sump pits & crawl spaces
Lake homes and converted cabins often have sump pits, open crawl spaces, and floor-wall joints — easy paths for radon to enter the South Haven homes families live in.

Central Minnesota sits in a high-radon region, and a lakeside address doesn't change that. A continuous-monitor radon test tells you exactly what's in the air on the lowest level of a South Haven home or cabin before you buy.

Radon is a colorless, odorless radioactive gas that rises from the soil and enters homes through foundation cracks, sump pits, crawl spaces, and floor-wall joints — all common in lake-home and cabin construction. We measure it with a continuous radon monitor placed on the lowest livable level under closed-house conditions, recording hourly readings over at least 48 hours.
Results are reported in picocuries per liter (pCi/L) and compared against the EPA action level of 4.0 pCi/L. It's a quick, valuable add-on to a full home inspection. Learn more about radon testing or about home inspection in South Haven, MN.

South Haven is a tiny lake town tucked on the Wright and Stearns County line, a stone's throw from Ramsey Lake and Maple Lake. Cabins, walkout lake homes, and small in-town houses all sit on the same central-Minnesota soils that push radon up into lower levels.

Lake homes and converted cabins often have sump pits, open crawl spaces, and floor-wall joints — easy paths for radon to enter the South Haven homes families live in.

South Haven sits squarely in central Minnesota's high-radon region; the lakeshore setting does nothing to lower the gas rising from the soil beneath the home.

Lake homes used year-round often turn the walkout lower level into prime living space, meaning longer daily radon exposure if it goes untested.
