Radon Mitigation in Quarry Hill and Apple Hill, Rochester MN

Radon work in Quarry Hill and Apple Hill, done by people who know the basements.

East Rochester, near Quarry Hill Park

East Rochester is where the limestone under your house stops being abstract. Quarry Hill Park is named for the limestone that came out of the hill, and the homes around it sit on or near the same rock. That shifts what's happening underneath the slab.

When the slab sits on rock

Quarry Hill Park is a former limestone quarry, and the rock that came out of it is the same formation running under the homes in the surrounding neighborhoods. In some places that rock is twenty feet down. In others it's much closer to the surface. Two homes on the same cul-de-sac can sit on completely different amounts of soil above the same bedrock.

Soil gas doesn't behave the same way in this kind of geology that it does elsewhere in Rochester. Instead of moving evenly through a uniform soil profile, it tends to find whatever crack or seam offers the easiest path. That makes the east side of the city a different kind of read than the west side.

Apple Hill has a similar story for similar reasons. The geology is what it is, and we plan visits to these homes accordingly.
