Commercial Radon & Soil Gas Services

Commercial Radon & Soil Gas Services

Basin Radon & Soil Gas provides commercial radon testing, radon mitigation, vapor intrusion mitigation, and LADBS methane systems throughout Los Angeles County. Everything below is work we self-perform; we do not broker it out.

If you are not sure which of these you need, that is normal and it is what the phone call is for. Most conversations start with the building and the reason somebody asked, and the right service falls out of that in about five minutes.

Commercial Radon Mitigation

Sub-slab systems designed off diagnostics, installed around occupancy, verified before we invoice.

Commercial Radon Testing

ANSI/AARST protocol measurement with continuous monitors and reports that survive review.

Multifamily & Apartment Radon

Lender-driven testing across occupied apartment properties, tenant coordination included.

School & Childcare Radon

Classroom-level results, HVAC-aware design, loud work scheduled for breaks.

Office Building Radon

Often solved at the air handler before anyone touches the slab.

Warehouse & Industrial Radon

Big slabs, few suction points, pipe routed clear of forklifts and racking.

Healthcare & Senior Living

Containment, infection control, and residents who cannot be relocated.
