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 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.

Three steps. On your timeline.
Measure your radon level.
We start with a measurement of what is actually in the air your family breathes. You see the result we see, and we walk through what it means in plain language.
You see the picture first.
Once you have the result, we talk through what your home is dealing with. No scripts, no pressure. You decide what to do next on your own timeline.
A conversation about your home.
If you want to take action, we look at the basement together and talk through what a plan for your foundation could look like. Every home is its own conversation.
Other Rochester neighborhoods we cover.
Century Hills
Most of the Century Hills and Cassidy Ridge calls we get are from buyers, not owners. The closing date is already on the calendar, the inspection came back with a number, and the question is what to do with the time between now and the walkthrough.
Hart Farms and Mayo Woodlands
Most of the homes in Hart Farms and Mayo Woodlands are custom builds, and a custom build doesn't look like the house next door. The walkout, the bonus room over the garage, the slab-on-grade addition. Each of those is its own thing.
Slatterly Park
Most of the Slatterly Park calls we get come from a buyer in the middle of a home inspection with two weeks to closing and a radon number that came back higher than expected. We know the pace those conversations move at.
