That doesn't mean every home is high, but it does mean every home should be tested. ### You can’t see or smell it Radon is invisible and odorless. A home can look perfect and still test high. Testing is the only way to know. ### Iowa soil makes it Glacial soils left by the Des Moines Lobe hold uranium that breaks down into radon gas, which seeps into basements and slabs. ### 4.0 pCi/L is the line The EPA recommends fixing any home at or above 4.0 pCi/L. Many Central Iowa homes test above it. ### Deadlines don’t wait A high result during a home sale can stall closing. A fast test and a one-visit install keep things moving.

Builder details [/new-construction-radon-systems/ →](/new-construction-radon-systems/) Radon Mitigation in Des Moines ## How Does a Radon Mitigation System Work? Most homes we fix use **sub-slab depressurization (SSD)**, a type of active soil depressurization. A fan creates gentle suction under your basement floor, so soil gas gets pulled into a pipe and vented outside before it can seep into your home. Crawl spaces get **sub-membrane depressurization**: a sealed plastic membrane over the dirt with suction underneath. Many Central Iowa homes have both a basement and a crawl space or slab addition, and we design for each. Before we install, we may run a quick **pressure field extension (PFE)** test to see how far suction reaches under the slab. That tells us if one suction point is enough or if your home needs two. The result: homes above the EPA's 4.0 pCi/L action level routinely drop below 1.0 pCi/L, with up to 98.9% radon reduction. Every install ends with a post-mitigation test, and every system carries a 5-year warranty.

Pricing ## How Much Does Radon Mitigation Cost in Des Moines? We don't guess at prices over the phone. Cost depends on your house, so we give you a firm quote after a short on-site assessment. 01 ### Foundation type A basement, slab-on-grade, crawl space or a mix of these each need a different design. Combined foundations may need more than one suction point. 02 ### Number of suction points Tight soils or a large footprint can need a second extraction point. The PFE test tells us what your slab needs. 03 ### Pipe routing An interior route through the garage or attic is cleaner looking. An exterior route along the siding is often simpler. We show you both. 04 ### Sealing work Open sump pits get an airtight lid and major slab cracks get sealed. Crawl spaces need a sealed membrane. Free Tool ## Already Have a Radon Test Result?

A verified result at the end. 1. 01 ### Test Start with a professional continuous-monitor test, or send us your existing result. We help you read the number and decide if mitigation makes sense. 2. 02 ### Assess A technician checks your foundation, sump, cracks and pipe routes, and may run a pressure field extension (PFE) test to see how air moves under the slab. 3. 03 ### Install Most single-family installs are done in one visit, typically within a day. We seal the sump and major cracks and label the system. 4. 04 ### Verify We check the manometer and schedule a post-mitigation clearance test, run at least 24 hours after the fan starts, to confirm your new level. Most single-family installs are completed in one visit, typically within a day. ## Got a high radon result? Talk to a credentialed technician tonight.

The EPA recommends fixing your home if radon is 4.0 pCi/L or higher, and suggests considering mitigation between 2.0 and 4.0 pCi/L. The World Health Organization uses a lower reference level of 2.7 pCi/L. Our systems routinely bring Central Iowa homes below 1.0 pCi/L. ### How much does radon mitigation cost in Des Moines? Cost depends on your foundation type, how many suction points the home needs, and whether the pipe runs inside through the garage or outside the house. We give you a firm quote after a short on-site assessment, and every system includes a 5-year warranty. ### How long does a radon mitigation install take? Most single-family installs are completed in one visit, typically within a day. We then schedule a post-mitigation test to confirm the system is working. ### Do you offer a warranty on radon systems? Yes. Every system and installation we complete is covered by a 5-year warranty. ### Are your technicians certified? Yes. Every technician who comes to your home is credentialed through the Iowa Department of Health and Human Services radon program and holds training from at least one of NRPP, NRSB, CERTI or ICA School. ### Do you serve Ames, Ankeny and the rest of Central Iowa? Yes. From our Franklin Plaza office in Des Moines we serve 12 Central Iowa counties, including Ankeny and Johnston in Polk County, Ames and Nevada in Story County, Waukee and Adel in Dallas County, and Pella and Knoxville in Marion County. ### How long does a professional radon test take? A short-term professional test runs for at least 48 hours under closed-house conditions. We use continuous radon monitors, which record hourly readings, so you get your results quickly after the monitor is picked up. ### Can you test during a home sale inspection period? Yes. We schedule real estate tests around inspection deadlines and use tamper-resistant continuous monitors so buyers, sellers and agents can rely on the results. ### My new home has a passive radon pipe but still tests high. Can you fix it? Usually, yes. Adding an inline fan and a manometer to an existing passive stack turns it into an active system, which typically lowers levels a lot more than a passive stack can. We retest afterward to confirm. ### Still have a question? Real people answer our phone 24/7. Ask about a test result, a quote or your existing system.
