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.

1.  1
    
    ### Test
    
    A 48-hour continuous radon monitor test in your home, or send us an existing result.

2.  2
    
    ### Design
    
    We review your foundation, slab sections and sump, then pick suction points and routing.

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."

Megan T. · Des Moines

★★★★★

> "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."

Chris L. · Waukee

★★★★★

> "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."

Local knowledge

## Radon in Sherman Hill

RADON HERE

### 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.
