Why Mold Shows Up in Thurston County

Thurston County sits at the southern end of Puget Sound, and Olympia averages around 50 inches of rain a year, most of it between October and April. The county mixes early-1900s homes around the Capitol, decades of suburban growth in Lacey and Tumwater, a large rental market near Joint Base Lewis-McChord, and fast-growing newer construction out toward Yelm. Every one of those housing types has its own way of hiding moisture.

What’s Included in a Complete Mold Inspection

A thorough walkthrough, the right tools, lab-backed sampling on request, and a written report you can hand to insurance, your buyer, or your remediation contractor. No corners cut, no padding the bill.

Visual & moisture walkthrough

Every accessible area inspected — living spaces, bathrooms, kitchens, basements, crawlspaces, attics, utility rooms. We document moisture readings, humidity levels, and any visible signs of growth or water intrusion.

Thermal & infrared imaging

Thermal imaging reveals temperature anomalies behind walls and ceilings — the cold spots that indicate hidden moisture from leaks, condensation, or vapor intrusion. Included on every Complete Mold Inspection at no extra charge.

Optional air sampling

Air samples capture mold spores from the indoor environment and ship to the lab for species identification and concentration measurement. Most useful when there are health symptoms but no visible growth, or for real estate documentation.

Optional surface sampling

Tape-lift or swab samples from suspected growth, sent to the lab for confirmation and species ID. Especially useful when you can see something but don’t know if it’s mold — or which kind.

Written photo-documented report

A PDF report with every area inspected documented, photo evidence, moisture readings, lab results (when sampled), and clear plain-English recommendations. Formatted to share with insurance, realtors, or remediation contractors.

Honest pre-call

If your situation doesn’t actually need an inspection, we’ll tell you on the phone before booking. We make zero money turning away non-jobs — we just don’t want to charge you $150 for a problem that didn’t exist.

Don’t get spored into spending $2,500 on a mold inspector.
