Swab Testing

Same-day and next-day appointments are usually available across our Seattle 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.

Seattle's most prevalent mold issues stem from the city's persistent rainfall and limited drying time between weather events. Crawl spaces are the single most common problem area — the combination of ground moisture, inadequate vapor barriers, and poor ventilation creates conditions where mold on floor joists and subfloor sheathing is routinely found even in otherwise well-maintained homes. Attic mold from insufficient ventilation relative to the moisture load is the second most frequent finding, followed by window-adjacent wall mold in older homes where single-pane glazing generates chronic condensation during the colder months.

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 Seattle fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.
