Know the risk

Radon Risks in Sherman Hill Homes

High radon is the norm in Central Iowa, not the exception. Here is what that means in Sherman Hill.

  • 01

    EPA Zone 1

    About 71% of Iowa homes test above 4.0 pCi/L. Your neighbor's number says little about yours. A 48-hour test is the only way to know.

  • 02

    Worse in Winter

    When the furnace runs and the ground freezes, warm air rises out of the house and pulls soil gas in through the slab.

  • 03

    Delays Closings

    A high radon test during inspection can hold up a sale. We test and install inside your inspection window.

How it works

How We Lower Radon in Sherman Hill Homes

Most homes are finished in one day. We test every system before we call it done.

Reviews

Reviews From Sherman Hill Homeowners

★★★★★

"Our Beaverdale house tested high during the inspection and the sale was on hold. They got a sub-slab system in quickly, the post-test came back low, and we closed on time."

★★★★★

"Our new build in Waukee came with a passive pipe but still tested above 4. They added the attic fan and manometer in one visit and explained the readings."

★★★★★

"Fan alarm went off on a Sunday night. I called the 24-hour line, got answers right away and a fan replacement booked for Monday."

Crawlspaces and Historic Foundations

Sherman Hill homes often combine a partial basement with dirt crawlspaces under later additions. Rubble and fieldstone walls leak soil gas through every gap, and bare dirt floors give radon a wide open path into the house.

We encapsulate crawlspaces with a heavy poly vapor retarder sealed to walls and piers, then pull suction from under it. When the home also has a basement, we tie both areas into one system when possible. Routing is planned to respect the home's historic look.

LOCAL HOMES

Foundations in Sherman Hill

Rubble and fieldstone walls. These walls are porous and uneven. Sealing them fully isn't realistic, so suction under the floor or membrane does most of the work.

Dirt crawlspaces. A 10 to 20 mil membrane, sealed at the seams and edges, plus sub-membrane depressurization is the standard fix.

Converted multi-family. Owners renting out units benefit from durable systems, visible manometers and regular retests.
