Mold Testing

State-certified testing that spots hidden mold—so you can act early, stay safe, and avoid costly repairs.

About

Why Mold Testing Matters

Mold isn't always visible. It hides in air vents, under floors, and inside walls. The only way to know what you're breathing—or what's spreading—is through lab-grade testing.

  • Identify mold species and spore levels
  • Detect hidden growth in "clean" areas
  • Assess the health risk to occupants
  • Decide on the right next steps
Why Mold Testing Matters

Methodology

How our mold testing works

The three sampling methods we use, chosen for what your property is showing

Sterile swabs and clear adhesive tape collect mold from visible spots on dry surfaces, giving the lab a clean sample for species identification. Suitable for walls, ceilings, baseboards, and furniture where the residue is what you're checking.

For damp or recently water-damaged areas, the sampling approach changes. Wet sampling captures live, actively growing colonies that dry methods underrepresent, which matters under flooring, behind tile, and around recent leaks.

A calibrated pump pulls a controlled volume of air through a spore trap cassette, capturing viable and non-viable spores from the breathing zone. The lab counts species and compares concentrations to outdoor levels, telling you whether your indoor air is healthy.

Mold inspection Bellevue FAQ

Call For An Inspection
Same-day and next-day appointments are usually available across our Bellevue 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.
Yes. Newer construction — including high-end custom homes and luxury condominiums — is not immune to mold. In Bellevue's premium market, the most common mold findings in newer buildings involve HVAC condensation issues in tightly sealed building envelopes where moisture has no pathway to escape, waterproofing failures in below-grade areas and attached garages, and window or curtain wall installation defects that allow water intrusion at the framing level. Pre-purchase mold inspections are increasingly standard practice in Bellevue's real estate market, and post-construction inspections before warranty periods expire are a cost-effective way to catch moisture issues while the builder is still responsible for corrections.
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 Bellevue fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.
