Radon Mitigation in Sherman Hill
Sherman Hill is historic Victorian homes, converted multi-family houses and older brick apartment buildings. Many sit on rubble, fieldstone or early brick foundations with dirt crawlspaces, which call for heavy-duty membranes and targeted sub-membrane suction.

Sherman Hill radon expertise
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.

Housing & foundations
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.

What Des Moines Customers Say
"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."
Radon Questions From Sherman Hill
Can you mitigate radon in a dirt crawlspace?
Yes. We install a heavy poly membrane sealed to the walls and piers and pull suction from beneath it.
Do fieldstone foundations need special handling?
Yes. They're porous, so suction under the floor or membrane does most of the work, with sealing where it helps.
Can one system cover a basement and a crawlspace?
Often. We tie both areas into one fan when the layout allows.
Will the system change how my Victorian looks?
We route pipe to stay out of sight from the street whenever possible.
