Air Testing

Mold air testing detects airborne spores and assesses indoor air quality, even in spaces where no visible contamination has shown up yet.

Overview

Why mold air testing matters

Most mold is invisible. Spores float undetected through ducts and doorways, spreading from room to room with the air itself. Air testing reveals the species and concentration of what's airborne, even when no visible growth is found on any surface.

Mold air testing detects:

  • Invisible mold spores circulating through the air
  • Differences in spore levels from one room to the next
  • Contamination inside HVAC systems and hard-to-reach areas
  • Early warning signs in rooms that appear unaffected

Benefits

What you get from air testing

Understand the air quality and find what your eyes can't

  • Non-invasive: No drilling, no surface damage, no demolition needed.
  • Early detection: Catch contamination before it spreads or symptoms start.
  • Data-driven: Measure and compare spore counts room by room with lab-verified results.
  • Defensible documentation: State-certified lab results that hold up for insurance and real estate use.

About

How mold air testing works

Our certified mold inspectors use calibrated sampling pumps to draw air through a spore trap cassette, capturing airborne mold spores. The lab identifies the mold species under a microscope, including any HVAC contamination if the system is implicated.

Our process includes:

  • Targeted sampling in problem areas and comparison sampling outdoors
  • Spore traps or impactor cassettes calibrated for accurate collection
  • Lab-verified results identifying species and spore counts
  • A written mold inspection report with the numbers and next steps

Mold inspection Seattle FAQ

Call For An Inspection
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.
