They measured first, then designed one system that covered everything. The pipe is hidden in a closet." Lauren M. · Country Club area ★★★★★ > "Quiet, clean and they explained the manometer.

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.

ZIP codes: 50325 FAQ ## Radon Questions From Clive Homeowners ### 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. ### 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. ### 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. ### 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. ### 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.
