Service overview
What mold air quality testing Burien WA involves
Mold air quality testing Burien WA measures the type and concentration of mold spores in the indoor air and compares them with an outdoor sample taken at the same time. A calibrated pump draws a set volume of air through a spore trap cassette, which is sent to an accredited lab for analysis. The report lists spore types and counts per cubic meter for each room sampled. When indoor counts are higher than outdoors, or when indoor air contains types that are uncommon outside, such as Stachybotrys or Chaetomium, it points to an indoor source. Air testing is most useful when you smell mold but cannot find it, when someone in the home has unexplained allergy or breathing symptoms, before buying or renting a property, and after a water event to confirm whether hidden growth developed. We pair air samples with a visual inspection, moisture readings, and thermal imaging so the results mean something. If you are searching mold air testing near me, ask whether the company includes an outdoor control sample. Without it, the numbers are hard to interpret.
! Common warning signs
Musty smell with no visible mold
Odor without visible growth usually means mold is hidden in a wall, ceiling, crawl space, or HVAC system. Air sampling can confirm it.
Allergy or breathing symptoms that ease outside the house
Symptoms that improve when you leave home and return when you come back are a common reason people order air testing.
Recent leak or flood that was dried
Air testing after a water event shows whether hidden growth developed in places that were not opened up.

-
03
Accredited lab analysis
Samples go to an accredited lab that identifies spore types and counts. Results usually come back in two to three business days.

Why Burien homeowners order air testing
Mold does not stop at the surface you can see. These are the outcomes Burien homeowners tell us matter most after a job is finished.
Schedule inspectionTools and methods we use for air quality testing
Calibrated air sampling pump
Draws a measured volume of air through a spore trap cassette so the lab can calculate spores per cubic meter accurately.
Spore trap cassettes
Capture airborne mold spores and particles for lab analysis. One cassette is used per sample location plus the outdoor control.
Thermal imaging camera and moisture meter
Help us choose sample locations and point to likely hidden sources when air results come back elevated.
Hygrometer
Measures temperature and relative humidity at each sample location, which helps explain why mold is growing.
Local execution
Burien's damp climate means outdoor mold spore counts are rarely zero, especially in fall and spring. That is exactly why an outdoor control sample matters here. Homes near the water in Shorewood, Seahurst, and Three Tree Point often have higher outdoor counts, and comparing indoor air against that baseline is the only fair way to read the results. Inside, we focus on rooms where people spend the most time and spaces connected to likely sources, such as rooms above a crawl space or next to a bathroom. Buyers and renters often order air testing in Downtown Burien and Olde Burien condos and apartments before signing. If you need mold air quality testing Burien WA, we keep the report clear: what was found, what it means, and what to do next.

Collect samples
Indoor samples are taken in each room of concern and an outdoor control is taken at the same time for comparison.
Lab results and report
The lab identifies spore types and counts. We explain the results and tell you whether remediation is recommended.

Additional testing
Surface swabs, tape lifts, or wall cavity samples can be added when air results point to a specific location.
Questions we hear about air quality testing
How much does mold air testing cost in Burien WA?
Typical 2026 pricing runs $300 to $600 for an inspection with two to three air samples including an outdoor control. Additional samples usually add $75 to $125 each.
Is air testing better than a visual inspection?
They work together. A visual inspection finds visible growth and moisture. Air testing shows whether hidden mold is affecting the air. Using both gives the clearest picture.
What is a normal mold spore count indoors?
There is no single legal limit. Indoor counts should generally be lower than outdoor counts and show similar spore types. Elevated indoor counts or unusual types point to an indoor source.
Can I use a home mold test kit instead?
Settle-plate kits from the hardware store almost always grow something, because mold spores are everywhere. They do not measure concentration or compare to outdoor air, so the results are hard to use.
