Radon Mitigation Challenges in Polk City Walkouts
The local problem
Walkout lake homes with two foundation levels above Saylorville
What you notice: The lower walkout level tests high, and it sits on a different slab from the rest of the basement.
Why it happens here: Polk City more than doubled between 2000 and 2020, with much of that building on sloped ground between Saylorville Lake and Big Creek, where walkouts with split slabs are common.
How we fix it: We measure suction under each slab section and design one residential radon mitigation system that reaches both, routed outside or through the garage.
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.

Walkouts and Well Water
Lake-area homes are often walkouts with more than one slab section, so we check suction reach before designing.
Homes on private wells outside city water should test water too, since radon in well water is released at taps and showers. We install waterborne radon systems when results call for it.

Polk City Radon Questions
Can one system cover a walkout basement near Saylorville Lake?
Often, yes. We measure suction under each slab section and tie them into one fan when the layout allows, so you have a single exhaust and one manometer to watch.
Should I test well water at a home near Big Creek?
If the home is on a private well, yes. Radon in water escapes into the air at showers and faucets. We test water and install waterborne systems when needed.
How do you reach Polk City?
We take Iowa Highway 415 from Ankeny or NW Beaver Dr through Johnston, so homes around the town square and the lake are a straightforward trip.
