Radon Mitigation in Clive With Quiet, Concealed Systems
Clive has many large custom floor plans with split slabs and cold joints where soil gas can enter. Pressure-field diagnostics help decide suction points, and owners often prefer concealed routing.

Radon Mitigation Challenges in Clive Homes
The local problem
Large remodeled homes where one suction point is not enough
What you notice: A system was installed years ago, the house was expanded since, and the latest test is back above 4.0 pCi/L.
Why it happens here: Clive more than quadrupled in the 1960s and doubled again in the 1970s, so many homes are now 45 to 60 years old and have had additions poured against the original slab.
How we fix it: We retest, measure suction under each slab section and either add a suction point or replace the fan as part of radon system maintenance, then verify with a post-mitigation test.
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
"I'm a seller and wanted to know before listing. They placed the monitor Tuesday and I had the report by Thursday afternoon."
"Our house is big and has three slab levels. They measured first, then designed one system that covered everything. The pipe is hidden in a closet."
"Quiet, clean and they explained the manometer. Post-test was way down from where we started."

Local logistics
Serving Clive From Northwest Des Moines
Clive is a quick trip from our Franklin Ave office along University Ave, Hickman Rd or I-235. We reach homes near the Clive Greenbelt Trail, the Country Club area and the neighborhoods along Walnut Creek without a long drive.
Larger homes often need a diagnostics visit before the install. We can schedule both close together so you're not waiting weeks between steps.
Local homes
Large Custom Homes and Split Slabs
Big footprints. Many Clive homes are large custom builds with additions, three-car garages and lower levels that step down with the lot. A bigger footprint means suction has farther to travel under the slab.
Cold joints. Where one slab pour meets another, there's often a cold joint. Soil gas can come through that seam even when the rest of the floor is tight, so we seal it as part of the job.
Concealed routing. Owners here often want the system out of sight. We plan interior routes through mechanical rooms, closets and garages into the attic, and choose quiet fans sized to the measured suction.

Radon Questions From Clive Homeowners
Can you hide the radon pipe in a larger custom home?
Often, yes. We look for routes through mechanical rooms, closets, chases and attached garages into the attic, so only a short exhaust shows above the roofline on homes near the Clive Greenbelt and Country Club area.
My Clive home already has a system. Why is the level high again?
Additions, new flooring cuts and aging fans can all reduce suction. Many homes here date to the 1960s and 1970s and have been expanded since. We retest, check the manometer and add a suction point or replace the fan if needed.
What is a cold joint and why do you seal it?
A cold joint is the seam where two concrete pours meet, such as an addition against the original slab. Soil gas can enter there even when the rest of the floor is tight, so we seal it during the install.
Will the fan be noisy in a quiet neighborhood?
Fans mounted in an attic or garage are usually hard to hear from living space. We size the pipe and fan to the measured suction so you do not get the air rush that causes most noise complaints.
Do you test homes for real estate deals along Hickman Rd and University Ave?
Yes. We place a 48-hour continuous radon monitor timed to your inspection contingency and send an hourly report that buyers, sellers and lenders accept.
Still have a question?
Our support line answers 24 hours a day, 7 days a week.
