# Radon Mitigation in Sherman Hill

Last updated: October 27, 2026

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.

Straight Answers

## Radon Questions From Sherman Hill

### Can you mitigate radon in a dirt crawlspace?

expand\_more

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?

expand\_more

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?

expand\_more

Often. We tie both areas into one fan when the layout allows.

### Will the system change how my Victorian looks?

expand\_more

We route pipe to stay out of sight from the street whenever possible.
