Radon Mitigation Problems in West Des Moines Homes
The local problem
A walkout basement with two slabs and finished walls in the way
What you notice: The test came back high, but the lower level is finished and nobody wants a pipe running through the family room.
Why it happens here: Most of the city was built after 1990 as it spread west into Dallas County, and many of those lots slope into walkouts with a basement slab plus a second on-grade section.
How we fix it: Residential radon mitigation starts with a suction test under both slab sections, then routes one fan through a storage room, garage or exterior wall.
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.

Reviews From Local Homeowners
"We have a walkout and didn't want pipe through the finished side. They ran it through the storage room and up through the garage. You can barely hear the fan."
"Old house, open sump, rough floor. They sealed everything and the post-test came back well under 4. Clear explanation the whole way."
"Buyer's inspection flagged radon. Install was done before our closing and the report was ready for the lender."

West Des Moines Homes We Work On
Walkout and finished basements. Many homes around Jordan Creek and Glen Oaks have walkouts with part of the basement on grade. That often means a second slab section, and finished walls limit where the pipe can go. We usually route through a storage room or utility area and up through the garage into the attic, or run an exterior system on a side wall.
Older homes near Valley Junction. Houses in the historic core often have block or older poured walls, open sump pits and rough slabs. Sealing is a bigger part of the job here.
Newer construction. Homes built since July 1, 2026 include a passive radon pipe under Iowa HF 2297. A post-construction test shows whether it needs an attic fan.

West Des Moines Radon Questions Answered
Do you serve all of West Des Moines, including the Dallas County side?
Yes. We cover Valley Junction, Woodland Hills, Clover Hills and the neighborhoods south of the Raccoon River, plus Jordan Creek, Glen Oaks and the newer Dallas County side reached by I-35/80.
Can you install a system without opening my finished walkout basement?
Usually, yes. Walkouts around Jordan Creek and Glen Oaks often have an unfinished storage or mechanical room. We put the suction point there and route through a closet or the garage, or run the pipe up an exterior side wall.
Do older homes near Valley Junction need extra sealing?
Often. Homes in the original Valley Junction core tend to have block or older poured walls, open sumps and rough slabs, so sealing the sump, cracks and floor-wall joint is a bigger part of the job than in a 2000s build.
Does flooding along Walnut Creek affect radon systems?
It can. Homes near Walnut Creek and the Raccoon River often have busy sump pumps. We seal the pit with a gasketed, airtight lid that still lets you reach the pump, so the system keeps its suction during wet seasons.
What drives the price of a system in a walkout home?
Mainly the number of slab sections, how far the pipe has to travel to avoid finished space, and sealing. A walkout with two slab sections costs more than a single basement slab. Send your result and a few photos for a written quote.
