## Radon Mitigation Problems in Adel Homes

The local problem

### Block and stone basements in the blocks around the Adel courthouse

**What you notice:** An older in-town basement tests high, and soil gas seems to come through the walls as well as the floor.

**Why it happens here:** Adel dates to 1847 and stayed small for more than a century, so the streets near the 1902 courthouse are lined with older homes on block or stone foundations that leak through hollow cores and mortar joints.

**How we fix it:** Residential radon mitigation here combines sub-slab suction with wall and sump sealing, and sometimes a second suction point.

### 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 knowledge

## Radon Reduction for Old and New Homes

Local logistics

### Reaching Adel

We reach Adel through Waukee on **US Route 6** or by I-80 and US Route 169, covering downtown near the **Dallas County Courthouse** and the newer neighborhoods along the Raccoon River Valley Trail.

Local homes

### Older Core, Newer Edges

Adel stayed small for most of its history, so homes near the courthouse square are often older houses with block or stone foundations and open sumps. These need wall and sump sealing along with a sub-slab system.

The population nearly doubled between 2010 and 2020, so the edges of town are newer. Those homes may have passive pipe that should be tested after move-in.

Straight Answers

## Adel Radon FAQs

### Can you mitigate older stone basements near the Adel courthouse?

expand\_more

Yes. Stone and block walls let soil gas through mortar joints and hollow cores, so we seal the walls and sump along with sub-slab suction, and add a second point if diagnostics call for it.

### Do newer homes on the edge of town need testing?

expand\_more

Yes. New homes can test high with or without a passive pipe. A 48-hour test after move-in tells you whether a fan is needed.

### Do you test homes for sale along the Raccoon River Valley Trail?

expand\_more

Yes. We schedule 48-hour continuous radon monitor tests inside inspection windows and send an hourly report.
