Your neighbor's number tells you little about yours, so a 48-hour test is the only way to know. ac\_unit ### 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. real\_estate\_agent ### 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.

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. ### Local facts that shape the job - fact\_check Clive lies in Polk and Dallas counties and uses ZIP code 50325.

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? expand\_more 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? expand\_more 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? expand\_more 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? expand\_more 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. phone\_in\_talk (515) 218-7447 [tel:+15152187447 →](tel:+15152187447) Send a Question [/contact/ →](/contact/) Nearby service areas ## Also Serving Near Clive - location\_on Urbandale [/service-areas/urbandale/ →](/service-areas/urbandale/) - location\_on West Des Moines [/service-areas/west-des-moines/ →](/service-areas/west-des-moines/) - location\_on Waukee [/service-areas/waukee/ →](/service-areas/waukee/) - All service areas [/service-areas/ →](/service-areas/) ![](/images/hero/radon-technician-loading-white-pvc-pipe-and-radon-.webp) 24/7 booking & support ## Get Radon Mitigation in Clive Scheduled Credentialed testing and mitigation with 24/7 booking, a post-mitigation test and a 5-year warranty on systems and installs.
