Radon Mitigation Problems in Ottumwa Homes
The local problem
Hillside basements in Ottumwa's bluff-top historic districts
What you notice: The basement is partly dug into a slope, one wall is fully buried, and the radon level is high.
Why it happens here: Housing climbed the river bluffs after 1859, and neighborhoods like Court Hill and Vogel Place have older homes with partial hillside basements and aging foundation walls.
How we fix it: Residential radon mitigation places suction near the buried side, seals the walls and sump, and routes the pipe up the downhill side of the house.
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.

Local homes
Bluff-Top and Older Homes
Ottumwa peaked at nearly 34,000 residents in 1960, so the city has a large stock of older homes. In the historic districts on the bluffs, such as Court Hill and Vogel Place, basements are often dug partly into the hillside.
These homes need wall and sump sealing and careful suction placement along with a sub-slab system.
