## Radon Mitigation Problems in Creston Homes

The local problem

### Railroad-era Creston homes on stone and brick foundations

**What you notice:** An older house near downtown tests high, and the basement walls are stone or brick with crumbling mortar.

**Why it happens here:** Creston grew up as a railroad division point starting in 1868, so many in-town homes date from the railroad boom and sit on stone or brick foundations that leak soil gas through the joints.

**How we fix it:** Residential radon mitigation here combines wall and sump sealing with sub-slab suction, and a crawlspace membrane where needed.

### 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.
