Air Testing

Same-day and next-day appointments are usually available across our Renton service area, with 24/7 emergency response for active leaks, recent water damage, or urgent real estate timelines. Standard scheduling runs 1 to 3 business days depending on availability.

Our certified mold inspectors assess bathrooms, kitchens, laundry rooms, basements, attics, crawl spaces, HVAC components, and any area showing signs of past or current water issues. Thermal imaging and moisture meters identify hidden moisture behind walls and under floors.

Properties in Renton's lower-elevation areas near the Cedar River and the southern Lake Washington shoreline sit in a zone where the water table is seasonally elevated and where flood events — even minor ones — can introduce moisture into crawl spaces and lower-level areas that persists long after the water recedes. The Cedar River corridor specifically has a history of flooding that affects homes in the valley-floor neighborhoods, and even properties that have not flooded in recent years may carry residual moisture damage in crawl spaces and subfloor systems from earlier events. We recommend any property within the flood-influence zone of the Cedar River receive a crawl space inspection as a baseline, regardless of visible symptoms.

Pricing varies based on the size of the property, the scope of testing required, and whether any lab work is included. Most residential mold inspections in Renton fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.
