Mold Inspection & Testing Burien WA you can trust
When you need mold inspection and testing Burien WA homeowners rely on, we find the source instead of guessing at the stain. Our technicians inspect, sample, and document every room, then hand you a clear lab report you can act on. If you have smelled something musty since the fall rains started, a Burien mold assessment tells you exactly what is growing and where.
Service overview
What mold inspection and testing Burien WA involves
Mold inspection and testing Burien WA is a diagnostic service that locates moisture problems, identifies what is growing, and confirms whether the air inside your home is affected. We walk the whole house with a moisture meter and thermal imaging camera, check the crawl space, attic, and bathrooms, then take air and surface samples where readings point to a problem. Samples go to an accredited lab, and you get results with species names and spore counts, not a sales pitch. Burien homes sit in one of the wettest corners of King County, and the rain that starts in October rarely lets up until spring. That steady moisture finds its way into crawl spaces, window frames, and old bathroom fans that vent into the attic instead of outside. If you have noticed a musty odor or a dark ring on the drywall, professional mold testing near Burien gives you a straight answer before a small problem turns into a demolition project.
! Common warning signs
Musty odor with no visible mold
A persistent musty smell usually means growth is hidden behind drywall, under flooring, or inside the HVAC system. Ignoring it lets spores circulate through the house and can worsen allergies and asthma symptoms.
Crawl space moisture after heavy rain
Standing water or damp soil in a crawl space raises humidity in the whole house. Framing and insulation stay wet, and mold starts within 48 to 72 hours of a water event.
Staining on ceilings or walls
A dark ring or spreading stain usually means an active leak, not an old one. Painting over it traps moisture and lets mold grow inside the wall cavity.
Scope of work
What is included in our mold inspection and testing
Every inspection includes a full visual walkthrough, moisture readings, and a written report. Sampling is included where readings indicate a problem, and we tell you the cost of additional samples before we take them. If remediation is needed, the report defines the scope so you can compare bids or move forward with us.

01
Full visual inspection
We walk every room, the crawl space, the attic, and the mechanical areas. We look for staining, warping, musty odor, and visible growth, and we check the building envelope for the moisture paths that feed mold.
-
02
Moisture and thermal readings
A moisture meter gives us percentage readings in walls and framing, and a thermal imaging camera shows temperature differences that reveal hidden moisture. We record readings in the report so you can see exactly where the problem is.
-
03
Air and surface sampling
Where readings point to a problem, we take air samples with a calibrated pump and surface samples with swabs or tape lifts. Samples go to an accredited lab, and results include species and spore counts.
-
04
Written report and scope
You get a report with photos, moisture readings, lab results, and a recommended scope in square feet. That document is what insurers, landlords, and real estate agents expect, and it is what you need to decide what comes next.
Why a proper mold assessment matters
Guessing at mold costs more than testing for it. A documented assessment tells you what is growing, how far it has spread, and whether the air in your bedrooms is affected, so you can fix the cause instead of painting over it.
Schedule inspectionTools and methods we use
Moisture meter
Gives percentage readings in drywall, framing, and subfloor so we know exactly where moisture is elevated and how far it has traveled.
Thermal imaging camera
Shows temperature differences behind walls and under floors, revealing hidden moisture that a visual inspection would miss.
Boroscope
A small camera on a flexible probe that lets us look inside wall cavities and ductwork without cutting large openings.
Calibrated air sampling pump
Draws a known volume of air through a spore trap so the lab can report spores per cubic meter and compare indoor and outdoor levels.
Local execution
Burien sits in a marine climate where the rain starts in October and keeps going through spring. That means crawl spaces stay damp, attic condensation is common, and bathroom fans that vent into the attic instead of outside create the perfect conditions for growth. We inspect with that pattern in mind, checking the crawl space and attic on every job, not just the rooms where you noticed a problem. Homes near Lake Burien and along the Seahurst bluffs see more foundation moisture, while older ramblers in Boulevard Park often have original bathroom fans and unsealed crawl space vents. If you need a licensed mold inspector Burien WA homeowners can call, we follow IICRC S520 protocols and send samples to an accredited lab. We also know the King County permitting process for remediation work, so the scope in our report matches what the county expects to see.

When you need answers quickly, we answer
Most inspections are scheduled within two to three business days, and we hold same-day slots for urgent situations like a burst pipe or a sewage backup. Our technicians carry moisture meters, thermal cameras, and sampling equipment on every truck, so we can inspect and sample in one visit. If you call in the morning, there is a good chance we can be at your door by afternoon. We also keep air scrubbers and dehumidifiers on hand for water damage that needs immediate drying before mold has a chance to start. For landlords and real estate agents working against a deadline, tell us the timeline when you call and we will tell you honestly what is possible.
How our inspection process works
Phone intake
We ask what you have noticed, when it started, and whether there has been a leak, flood, or sewage backup. That conversation takes about ten minutes and lets us bring the right equipment. If you need same-day mold inspection Burien WA scheduling, call early in the day and we will tell you honestly what is open.
On-site walkthrough
A technician walks the home with you, room by room, checking the crawl space, attic, bathrooms, kitchen, and any area where you have seen staining or smelled odor. We use a moisture meter on walls and framing and a thermal imaging camera to spot temperature differences that reveal hidden moisture.
Sampling
Where readings point to a problem, we take air samples with a calibrated pump and surface samples with swabs or tape lifts. Samples are labeled, sealed, and sent to an accredited lab. Most inspections take two to four hours depending on square footage and how many samples are needed.
What mold inspection and testing costs
Inspection pricing in 2026 runs $350 to $650 for most homes, with additional samples at $75 to $125 each. The price depends on square footage, how many areas need sampling, and whether the crawl space and attic are accessible. We quote the full price before we start, and if the lab results show no problem, we tell you that. A professional mold testing near Burien appointment costs less than removing the wrong materials based on a guess.
Home size and layout
A 900-square-foot bungalow takes less time to inspect than a 2,500-square-foot split-level with a finished basement. Square footage affects the number of samples needed and the time on site.
Number of samples
A basic inspection includes two air samples, one indoor and one outdoor baseline. Each additional sample, whether air or surface, adds $75 to $125 depending on the lab.
Access and conditions
Crawl spaces with limited access or standing water take longer to inspect safely. If the attic or crawl space is difficult to reach, the inspection may require more time and equipment.
