Every spore testing job includes the on-site walkthrough, calibrated air sampling, an outdoor control sample, and a written lab report. Surface sampling and post-remediation clearance are add-ons we quote upfront if your situation calls for them.
A technician walks the house with a Protimeter moisture meter and a Flir thermal imaging camera, checking baseboards, window frames, under sinks, and crawlspace access. This is how we decide where to place sampling cassettes.
Zefon or SKC air sampling pumps running at 15 liters per minute for five minutes per cassette. We log the flow rate on every sample so the lab and your contractor can verify the numbers are valid.
One outdoor air sample pulled the same hour as the indoor samples. Without it, an indoor spore count is just a number. With it, you get a ratio that tells you whether the indoor air is actually elevated.
Samples ship same-day to an accredited lab for spore count and genus identification. Turnaround is 3 to 5 business days for air samples. We send tracking so you know when they arrive.
A report with raw counts, the outdoor baseline, and a plain-language read on what the numbers mean. If remediation is warranted, we flag the affected areas and the moisture source. If it isn't, we tell you that too.
Mold Spore Testing in Lacey is a diagnostic service that captures airborne mold spores on calibrated media and sends them to an accredited lab for species-level analysis. We run an air sampling pump at a set flow rate, usually 15 liters per minute for five minutes per cassette, and we pull an outdoor control sample at the same time. The lab compares indoor counts against that baseline, so you get a ratio, not a guess. A moisture meter and hygrometer readings go alongside it, because spores need water to grow and we want to know where the water is.
Most Lacey calls start with a smell, a stain, or a crawlspace that stays damp through winter. Thurston County sits in a marine climate where condensation on cold window frames and poorly ventilated bathrooms feed growth year after year. If you've had a leaky pipe under the sink or a roof that leaked last winter, spores can stay airborne long after the drywall feels dry. Testing tells you whether the problem is active, dormant, or already cleared, which is the difference between a $400 cleanup and a $9,000 tear-out.
Every job follows the same five steps, whether you're in a 900-square-foot Downtown Lacey bungalow or a 3,200-square-foot house out near Lacey Village. Here's exactly what happens from the phone call to the report in your inbox.
Schedule
Call or book online — a real human picks up and confirms a 2-hour arrival window.
Diagnose
Licensed tech inspects on-site, then walks you through the cause and your options.
Fix
The job is completed to code and done right the first time — no shortcuts, no surprises.
Guarantee
Every job backed by a written workmanship warranty — and we stand behind it.
Zefon and SKC air sampling pumps
Calibrated pumps that pull air through sampling cassettes at 15 liters per minute for five minutes. The flow rate is logged on every sample so the lab and your contractor can verify the numbers.
Air sampling cassettes
Single-use cassettes loaded with a spore-trapping medium. Each one captures a known volume of air, which is what lets the lab report spore counts per cubic meter instead of a vague positive or negative.
Protimeter moisture meter
Pin and pinless readings on drywall, framing, and flooring to find where water is sitting. Spores need moisture, so this is how we decide where to place sampling cassettes.
Flir thermal imaging camera
Infrared scanning that reveals temperature differences behind drywall and under flooring. It's how we find hidden leaks and wet cavities before we set up air samples.
Borescope
A camera on a flexible probe we feed into wall cavities and under flooring. It lets us look inside a suspect cavity without cutting a hole, and confirm what the thermal camera suggested.
Hygrometer and particle counter
Humidity and particulate readings that go alongside the spore counts. High humidity and elevated particulates tell us whether ventilation is part of the problem or just the mold is.
Tape lift and swab samples
Surface sampling for visible growth. A tape lift or swab gives the lab enough material to identify the species directly, including Stachybotrys, which air sampling alone can't always confirm.
Indoor vs. outdoor control comparison
Every job includes an outdoor air sample pulled the same hour as the indoor samples. The lab compares indoor counts against that baseline, so your report shows a ratio. An indoor count running 3x the outdoor control is a different conversation than one running at parity.
IICRC and ACAC sampling protocol
We follow IICRC and ACAC guidance on sample placement, volume, and chain of custody. That means documented flow rates, sealed cassettes, and same-day shipping to the lab. It's the difference between a report an adjuster accepts and one they question.
EPA and Washington State Department of Health reporting standards
Our reports follow EPA and Washington State Department of Health guidance on how spore counts are presented and interpreted. You get species, concentration per cubic meter, and the outdoor baseline in a format your contractor or adjuster already knows how to read.
Moisture-first diagnostics
We find the water before we interpret the spores. A moisture meter and thermal imaging camera pass comes first, then sampling. If there's no moisture source, there's no active growth, and the report says so instead of implying a problem that isn't there.
01
What we do: We run air samples in that room and the adjacent hallway, plus an outdoor control. A thermal imaging camera pass checks whether the insulation above the stain is still wet. If it is, we flag the cavity for repair.
→ You find out whether the dry-out worked or whether growth took hold behind the drywall, usually within a week of the visit.
02
What we do: We schedule a same-week visit, sample the crawlspace and the living space above it, and pull an outdoor control. The lab report comes back in 3 to 5 business days with species and counts.
→ Both sides get a document they can act on, and the contingency resolves without tearing the house apart.
03
What we do: We check the ceiling and window frames with a moisture meter, take a tape lift sample from the stain, and run an air sample in the bathroom. The lab identifies the species and the spore count.
→ You know whether it's surface growth from humidity or a deeper moisture problem, and what it takes to fix it.
04
What we do: We run post-clearance air sampling in the remediated area and compare it to an outdoor control. If counts are back to normal-range, you have proof the job worked.
→ You either release the final payment with confidence or you have documentation to push back before you do.
Lacey sits in a marine climate where condensation on cold window frames and poorly ventilated bathrooms feed growth year after year. Thurston County winters are wet and mild, which means crawlspaces and attics stay damp for months, and a leaky pipe or a roof that leaked last winter can leave moisture inside a wall long after the surface feels dry. We run spore testing the same way across every Lacey neighborhood, but the sampling plan changes with the building. A 1970s split-level near Downtown Lacey often has a crawlspace with no vapor barrier and original single-pane windows. A newer build out toward Hawks Prairie usually has tighter construction and a bathroom exhaust that vents into the attic instead of outside. Both scenarios show up in the lab report differently, and both need a moisture source identified before remediation makes sense. If you're searching for mold spore testing near me in Lacey, the answer is a same-week visit, calibrated pumps, and a report in your inbox within a week.
Downtown Lacey
Older housing stock with crawlspaces and original single-pane windows. Condensation and crawlspace humidity are the two most common moisture sources we find on spore testing calls here.
Lacey Village
A mix of rentals and owner-occupied homes. We run a lot of post-remediation clearance sampling here after bathroom and kitchen remodels uncover old water damage.
Hawks Prairie
Newer construction with tighter envelopes. Bathroom exhaust fans that vent into the attic instead of outside are a recurring source of elevated attic humidity and spore counts.
Marvin Road corridor
Larger lots with mature trees and roof debris. Gutters that clog and overflow against the foundation are a common cause of crawlspace moisture we document during testing.
Marine climate with wet, mild winters
Crawlspaces and attics stay damp from October through April, which gives mold a long window to establish. We see elevated spore counts in these spaces well into spring even after the rain stops.
Older housing stock with single-pane windows
Condensation on cold glass feeds growth on window frames and sills. We check these areas with a moisture meter on every walkthrough and sample nearby air when readings are high.
Tighter newer construction with poor exhaust
Bathroom and kitchen exhaust that vents into the attic instead of outside traps humidity in the roof cavity. Spore counts in the attic can run elevated even when the living space tests normal.
Seasonal roof and gutter leaks
Fall and winter storms push water against fascia and into wall cavities. By the time a ceiling stain shows, moisture has often been sitting behind the drywall for weeks, which is when growth takes hold.
Most of our Lacey calls come down to one of these four situations. Each one has a different testing approach, and each one has a different answer at the end.
Problem
You keep smelling it, you keep cleaning, and it keeps coming back. Without testing you're guessing at the source, and the growth keeps spreading behind the wall.
Our Fix
We run air samples in the room with the odor and in adjacent spaces, plus an outdoor control. If the indoor count is elevated, we use a borescope and thermal camera to find the wet cavity feeding it. You get the source, not just the smell.
Problem
A leaky pipe or a window that leaked last winter can leave moisture inside the wall long after the surface feels dry. Mold can colonize within 48 hours and go airborne before you notice.
Our Fix
We check the area with a moisture meter and thermal imaging camera, then sample the air in that room and the room next to it. If counts are elevated, we flag the cavity. If they're normal, you get documentation that the dry-out worked.
Problem
A buyer's inspector flags a musty crawlspace and the deal stalls. Without lab numbers, both sides argue over whether there's a real problem or just an old-house smell.
Our Fix
We sample the flagged area and a control location, get the lab report back in 3 to 5 business days, and give both sides a document they can act on. Most contingencies resolve without a full tear-out.
Problem
A contractor says the job is done, but you have no way to verify it. If spores are still elevated, you've paid for a cleanup that didn't finish the job.
Our Fix
We run clearance sampling in the remediated area and compare it to an outdoor control. If counts are back to normal-range, you have proof. If they aren't, you have leverage before you make the final payment.
Spore testing answers the question a visual inspection can't: is the air in your house carrying mold at levels that matter? These are the four outcomes our Lacey customers care about most.
Lab numbers, not opinions
You get a written report listing species and spore counts per cubic meter, plus the outdoor baseline we sampled the same hour. If the indoor count is running 3x the control, you have documentation. That report is what insurance adjusters and remediation contractors actually read.
Find the hidden source
Visible mold is maybe a third of the story. We use a thermal imaging camera and a borescope to check inside wall cavities and under flooring where a leaky pipe or failed shower pan has been feeding growth behind the drywall. Testing confirms what the camera suggests.
Clear a real estate contingency
Buyers and sellers in Lacey use spore testing to settle a mold contingency without tearing a house apart. We sample the suspect areas, document the counts, and give both sides a report they can act on before closing. Most jobs wrap in under two hours on site.
Verify a cleanup worked
After remediation, we run clearance sampling to confirm spore counts have dropped back to normal-range levels. If a contractor says the job is done, we can prove it with post-clearance numbers instead of taking their word for it. That's the difference between clean and covered up.
Google ★★★★★4.9
They tested our house after a pipe leak and found elevated counts in the wall behind the kitchen. Report was clear, lab turnaround was four days, and the remediation crew knew exactly what to do. No scare tactics, just numbers.
Yelp ★★★★★4.8
Used them for a real estate contingency in Lacey Village. They got out same week, sampled the crawlspace, and had the lab report back before closing. The seller ended up covering the cleanup because the numbers were documented.
BBB ★★★★★4.9
I manage rentals and use them for post-remediation clearance. They show up when they say, run the pumps, and send a report I can hand to the owner. Last job came back normal-range and we closed the file same week.
We've been running mold and air quality diagnostics in Lacey since 2015, which means 11 years of reading spore counts in Thurston County's specific climate. Our technicians hold IICRC and ACAC credentials, and we follow EPA and Washington State Department of Health guidance on sampling protocol and reporting. We've sampled crawlspaces, attics, basements, hotels, rentals, and post-remediation clearances across the county. We know what a normal Lacey spore profile looks like in February versus August, and we know when a number is worth worrying about and when it isn't.
Real answers to the questions we hear most often from local homeowners and property managers.
Surface sampling with tape lifts and swabs to identify the species growing on a specific wall, cabinet, or crawlspace joist. We pair it with spore testing when you need both the air picture and the source confirmed.
