Mold, asbestos, radon and air quality testing for homes in DC, Maryland and Virginia

Independent inspections for homeowners, buyers, sellers, landlords and tenants. We test, we report, we never sell the repair.

VOC and indoor air quality

Odors, new-construction off-gassing, formaldehyde, combustion by-products and HVAC investigations.

Had a fire? Smoke and soot testing shows which rooms and systems the smoke actually reached.

Seeing glass fibers on surfaces, or dust after HVAC or insulation work? Fiberglass testing counts the fibers in the air of the room.

Smell something you can't find? We look for the source, whether it is in the walls, the ductwork or your car.

Renting, own a rental or answer to a builder? We have pages for tenants, landlords and new-home warranty claims.
