The local problem ### Radon seeping between the levels of a 1970s split-foyer **What you notice:** The lower family room tests high even though the basement side looks sealed, and the reading jumps every winter. **Why it happens here:** Urbandale grew fastest in the 1960s and 1970s, when split-foyers and split-levels were poured as separate slabs. Soil gas finds the cold joint where those pours meet. **How we fix it:** We run a pressure field test under each slab, then design residential radon mitigation that ties a second suction point into one fan if the first cannot reach both levels. map ### 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. 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.

Douglas Ave, Merle Hay Rd and 86th St put us at most Urbandale homes in a short drive, and I-35/80 covers the neighborhoods near Living History Farms and the Dallas County side. That closeness makes it easy to fit testing and installs around your schedule, including real estate deadlines. Fan alarms and repair calls get booked through our 24-hour support line. Local homes ### Split-Foyer and Split-Level Homes **More than one slab.** Many Urbandale homes built from the 1970s through the 1990s are split-foyers and split-levels. The lower level may sit on one slab while a family room or garage sits on another, with a cold joint between them where soil gas can enter. **Drain tile and sump pits.** Perimeter drain tile tied to a sump is common. It can carry soil gas to an open pit, and it can also help extend suction once the pit is sealed. **Diagnostics first.** Before we drill, we check pressure field extension to see if one suction point reaches both slabs. If it doesn't, we tie a second point into the same fan so you don't need two systems. ### Local facts that shape the job - fact\_check Urbandale lies in Polk and Dallas counties, and its own ZIP codes are 50322 and 50323.

Straight Answers ## Urbandale Radon Mitigation FAQs ### Does a split-level home need two radon systems? expand\_more Usually not. We measure how far suction reaches under each slab. If one point will not cover both levels, we add a second suction point on the same fan, so you still have one system and one exhaust above the roof. ### Do you cover the Urban Loop and the Dallas County side of Urbandale? expand\_more Yes. Along with the Merle Hay and Douglas Ave corridors and Walnut Creek, we serve the newer homes in western Urbandale and the Urban Loop, reached by I-35/80 and Iowa Highway 141. ### Will you seal the sump pit in my lower level? expand\_more Yes. Many 1970s and 1980s split-levels have perimeter drain tile tied to an open sump. We fit an airtight, gasketed lid that still lets you service the pump, and the sealed tile often helps spread suction. ### Can you take over a system another company installed here? expand\_more Yes. Homes that changed hands often come with an older system and no paperwork. We check the manometer, fan and seals, replace failed fans and retest so you know the system still works. ### How soon can you schedule a visit near Merle Hay Rd? expand\_more Our Franklin Ave office is a short drive down Douglas Ave or Merle Hay Rd, so diagnostics and installs are often booked within days. Call our 24-hour line for the next open window. 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 Urbandale - location\_on Johnston [/service-areas/johnston/ →](/service-areas/johnston/) - location\_on Clive [/service-areas/clive/ →](/service-areas/clive/) - location\_on West Des Moines [/service-areas/west-des-moines/ →](/service-areas/west-des-moines/) - location\_on Grimes [/service-areas/grimes/ →](/service-areas/grimes/) - All service areas [/service-areas/ →](/service-areas/) ![](/images/hero/radon-technician-loading-white-pvc-pipe-and-radon-.webp) 24/7 booking & support ## Schedule Radon Mitigation in Urbandale Credentialed testing and mitigation with 24/7 booking, a post-mitigation test and a 5-year warranty on systems and installs.
