## 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?

expand\_more

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?

expand\_more

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?

expand\_more

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