The right fix starts with the right diagnosis

Reduce radon gas exposure with a proper mitigation system

The Piedmont geology underlying much of Northern Virginia and Maryland is associated with elevated radon potential, and the EPA recommends mitigation above 4 pCi/L. A mitigation system draws radon gas from beneath the slab or crawl space membrane and vents it safely outside before it can build up indoors.

Common problems we solve

  • A radon test result at or above the EPA action level of 4 pCi/L
  • An unsealed crawl space membrane that a radon system needs to seal against
  • No existing mitigation system in a home with known elevated radon risk
  • An older radon fan or system that may no longer be performing correctly

Benefits of a properly designed solution

Site-specific system design

Sub-slab or sub-membrane depressurization is designed around your home's foundation type, not a generic layout.

Coordinated with crawl space sealing

A properly sealed vapor barrier improves the effectiveness of a crawl space radon system.

Continuous protection

A functioning system runs continuously to keep radon levels below the action threshold, not just at the moment of testing.

Supports resale and real estate transactions

A documented, working mitigation system is often required or expected during DMV home sales.

Our four-step process

  1. Inspect: Document moisture, drainage, structure, and site conditions.
  2. Explain: Review findings with photos and straightforward priorities.
  3. Install: Complete the agreed scope with careful home protection.
  4. Verify: Test components, clean the work area, and complete a walkthrough.
Common questions

Radon Mitigation FAQs

Do I need a radon test before mitigation?+

Yes, a test establishes your baseline radon level and confirms mitigation is needed. We can advise on testing options as part of your inspection.

Is radon a real concern in the DMV specifically?+

The Piedmont geologic region covering much of Northern Virginia and parts of Maryland has known elevated radon potential, and testing is common practice in local real estate transactions.

How does a mitigation system work with an encapsulated crawl space?+

The system depressurizes the space beneath the sealed vapor barrier or slab and vents the collected gas outside through a fan and pipe, working alongside rather than against a sealed crawl space.
