Radon Mitigation for Oskaloosa Rentals and Older Homes

The local problem

Older rentals near William Penn University with no radon record

What you notice: A landlord buys an older house near campus and has no idea what the radon level is or whether anyone ever tested.

Why it happens here: Much of Oskaloosa's housing dates to its coal mining heyday, and many of those older houses near William Penn University are now rentals with frequent turnover.

How we fix it: We handle radon testing between tenants and install residential systems with clear manometers, so a quick check shows the fan is running.

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.

Straight Answers

Oskaloosa Radon FAQs

Do you test rentals near William Penn University?

Yes. We place a 48-hour continuous radon monitor between tenants and install durable systems with an easy-to-read manometer if the level is high.

Do older Oskaloosa homes need more sealing?

Often. Homes from the coal mining era tend to have block or stone walls and open sumps, so sealing is a larger part of the job alongside sub-slab suction.

Do you serve rural homes toward Lake Keomah?

Yes. We group Mahaska County visits on scheduled days, reached on Iowa Highway 163 and US Route 63.
