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.

Railroad-Era and Rural Homes
Creston grew as a railroad division point from 1868 on, and many homes near the historic depot date from that era. Older stone and brick foundations need wall sealing and careful suction placement.
Rural homes may have crawlspaces or private wells. We match the system to the foundation and water source.
