Radon Mitigation Challenges in De Soto

The local problem

A basement plus a crawlspace addition in an older De Soto house

What you notice: Part of the house sits over a basement and part over a dirt or gravel crawlspace, and the level stays high after one fix.

Why it happens here: De Soto has seen little new building, its population dipped between 2010 and 2020, so most homes are older houses that were expanded over time, often with a crawlspace addition beside the original basement.

How we fix it: We seal the crawlspace with a heavy membrane and tie it into the same fan as a sub-slab point as part of residential radon mitigation.

Every Iowa county is EPA Zone 1

About 71% of Iowa homes test above the EPA action level of 4.0 pCi/L. Your neighbor's number tells you little about yours, so a 48-hour test is the only way to know.

Winter makes it worse

When the furnace runs and the ground freezes, warm air rises out of the house and pulls soil gas in through the slab, sump and cracks.

High results stall closings

A failed radon test during inspection can hold up a sale. We test inside your contingency window and can install and verify a system before closing.

How it works

Most single-family homes are finished in one day, and every system is verified before we call it done.

Experience With Mixed Foundations

Local logistics

Serving De Soto

De Soto sits at the I-80 and US Route 169 interchange west of the metro. We reach in-town homes and rural Dallas County properties with a quick trip down the interstate.

Local homes

Older Homes, Mixed Foundations

The town grew up around the Rock Island railroad starting in 1868 and has stayed small. Many homes are older houses that were added onto, so a basement and a crawlspace often sit side by side.

We seal crawlspaces with a heavy poly membrane and pull suction from beneath it, tied into the same fan as the basement point. Homes on private wells should test water as well as air.

Straight Answers

De Soto Radon Questions

Can one system cover a basement and a crawlspace addition?

Often, yes. We seal the crawlspace with a membrane, run suction beneath it and tie it into the same fan as the basement point, which is common in older De Soto homes that were added onto.

Can radon come from my well near the I-80 corridor?

Yes, if the home is on a private well. Test the water as well as the air. We install waterborne radon systems when results call for it.

Do you serve rural homes outside De Soto?

Yes. We serve in-town homes and rural Dallas County properties reached from the I-80 and US Route 169 interchange.
