Mold inspection and testing in WA, Washington starts with a room-by-room search for the moisture feeding the growth. We check drywall, subfloor, insulation, and crawl spaces with moisture meters and thermal imaging cameras, then take air and surface samples for lab analysis. If you have smelled that musty odor since the last storm or a supply line leak, call us and get a clear answer.
Mold inspection and testing in WA, Washington is a diagnostic service that locates active mold growth, identifies the moisture source behind it, and confirms the findings with lab-analyzed air and surface samples. We do not just look for visible spots. We trace the water that got into your drywall, subfloor, or carpet padding and map how far the growth has spread. Every inspection ends with a written report you can hand to your insurance adjuster, your landlord, or a remediation crew.
Western Washington stays damp from October through April, and that long wet season is why mold inspection services WA homeowners call us most often between November and March. A roof leak, a burst pipe, or a slow supply line leak can soak insulation and hardwood flooring for weeks before you see a stain. By then, mold growth has already started in the dark cavity behind the baseboard. If you search for mold inspection and testing near me WA after a water event, we can be on site the same day.
Every inspection is a full diagnostic, not a quick swab. Here is what is covered in the standard price, and what we add only when the situation calls for it. You will know the scope before we start, and the report tells you exactly what we found and what to do next.
We inspect every room, the attic, the crawl space, and the exterior wall bases. We check baseboards, ceiling corners, under sinks, behind appliances, and the vapor barrier. This takes 45 to 90 minutes and catches growth that a spot check misses.
A moisture meter and thermal imaging camera read damp drywall, subfloor, and insulation without opening walls. A hygrometer confirms indoor humidity. This step finds the water source and shows how far the moisture has traveled.
We pull air samples with a calibrated pump and take surface samples from visible growth, plus one outdoor control sample. Samples ship the same day to an accredited lab for genus-level identification and spore counts.
You get a report with photos, moisture readings, lab data, and a clear recommendation. It is formatted for Xactimate so your insurance adjuster can process the claim. Results land in 24 to 72 hours.
If the lab confirms active growth, we scope the remediation in the same visit so you do not pay for a second inspection. The scope lists affected materials, containment plan, and post-remediation verification steps.
We ask what you smelled, saw, or what water event came first, then book a window that fits your schedule. You get a firm arrival time, not a four-hour block. If the call comes in after a burst pipe or a sewage backup, we treat it as priority and aim for same-day.
A technician walks the whole structure, not just the room with the stain. We check baseboards, ceiling corners, under sinks, behind appliances, the attic decking, and the crawl space. This usually takes 45 to 90 minutes depending on square footage and how many rooms show moisture readings.
We read every suspect surface with a moisture meter and scan walls and ceilings with a thermal imaging camera. A hygrometer confirms indoor humidity against outdoor conditions. This step tells us whether the growth is feeding on an active leak or leftover dampness from a past event.
Air samples are pulled with a calibrated pump, and surface samples are swabbed or taped from visible growth. We take an outdoor control sample so the lab can compare indoor spore counts against the baseline. Collection adds 20 to 30 minutes and the samples ship the same day.
You get a written report within 24 to 72 hours once the lab results land. It includes photos, moisture readings, lab data, and a clear recommendation: monitor, dry, or remediate. If remediation is needed, we scope it and can schedule the work without a second inspection.

Reads moisture content in drywall, subfloor, and wood framing without opening the wall. It tells us whether a material is wet enough to support mold growth.
Shows temperature differences behind walls and ceilings, revealing wet cavities and hidden leaks that a visual check would miss.
Measures indoor relative humidity against outdoor conditions. High indoor humidity with no visible leak points to a ventilation or vapor barrier problem.
Pulls a calibrated volume of air through a spore trap cassette. The sample goes to the lab for genus-level identification and spore counts.
A borescope that lets us look inside wall cavities and crawl spaces without cutting drywall. We use it to confirm growth and locate the moisture source.
HEPA filtration that captures airborne spores during remediation. We run it inside containment so spores do not spread to clean rooms.
A Downtown Puyallup homeowner smelled musty air in the basement for two months. A previous contractor quoted remediation without testing. Moisture readings showed 28% in the baseboard and the wall cavity behind it, and air samples came back with elevated Penicillium/Aspergillus spores.
After: We traced the moisture to a foundation crack, sealed it, dried the wall cavity, and remediated the affected drywall. Post-remediation air sampling came back at outdoor baseline levels. The homeowner had the report for the insurance claim within three days.

A Federal Way home had standing water in the crawl space after a November storm. The sump pump had failed, and the joists read 32% moisture. Visible mold was growing on the wood framing and the vapor barrier was torn in two places.
After: We removed the water, replaced the sump pump, dried the joists to dry standard, and treated the mold on the framing. Post-drying moisture readings dropped to 12% to 14%, and air sampling confirmed the crawl space was clear.

A University Place homeowner called a week after a windstorm. Water had pushed under the roof flashing and soaked the attic insulation. The attic decking read 26% moisture and surface samples confirmed early mold growth on the sheathing.
After: We repaired the flashing, removed the wet insulation, dried the attic framing, and remediated the sheathing. Post-remediation testing came back clean, and the report supported the insurance claim for the roof repair and insulation replacement.
Book this service →Most mold calls start with a water event that was never fully dried. These are the problems we see most often across the South Sound, and how we handle them.
Ask a pro →We use a thermal imaging camera and moisture meter to find the damp cavity, then take air samples room by room. The lab tells us the genus and count, and we trace it back to the water source so the fix is permanent.
We repair the leak, dry the cabinet base and subfloor, and test the cavity before the cabinet goes back in. Testing after the repair is closed up is too late to catch hidden growth.
We remove the standing water, dry the joists and vapor barrier, and test the wood framing before recommending encapsulation. If the sump pump failed, we repair or replace it as part of the fix.
We repair the roof leak, dry the attic framing, and test the decking and insulation. If the insulation is contaminated, we remove it and test the cavity again before new insulation goes in.
