Lab numbers, not guesswork
Sometimes you can't see the problem and you just want to know what the lab says. The dispatcher routes you to an independent, insured tester in Catlettsburg who sets up the pump, logs the volume and gets the cassettes to a lab the same day when possible.

How sampling works
At its core, mold testing is about capturing spores and letting a lab count them. The most common air method uses a spore-trap cassette on a calibrated pump. A typical run is 15 liters per minute for 5 minutes, so 75 liters of air pass over an adhesive strip inside the cassette. The lab counts and identifies what landed on that strip under a microscope, then converts the count to spores per cubic meter of air.
A single indoor count tells you very little without a comparison. Spores drift inside on every breeze, so the pro also pulls an outdoor baseline sample at the same time, and the lab compares the two. If indoor levels run well above outdoor levels, or the indoor sample is dominated by types like Stachybotrys or Chaetomium that rarely show up outside in any quantity, that points to an indoor source. There are no federal numeric limits for indoor spores, which is exactly why the outdoor comparison carries so much weight.
When there's a visible spot and you want it identified, surface samples come in. A tape-lift presses clear adhesive tape onto the growth, a swab works on rough or curved surfaces, and a bulk sample is a cut piece of drywall, carpet or insulation sent whole. For suspected growth inside a wall, some pros take a wall-cavity air sample through a small port. Folks in Catlettsburg usually call for testing to document conditions for a sale, a lease dispute or a clearance after remediation.
What separates good sampling
A sample that sat in a hot truck for three days or was pulled with an uncalibrated pump gives you a number you can't trust.
The professionals the line connects you with carry liability insurance and carry the state assessor credential if your state licenses mold sampling. A tester with no cleanup contract riding on the outcome just reports what the lab found.
Clearance tests often hold up a containment teardown or a closing, so timing matters. The dispatcher prioritizes urgent clearance and real estate calls in Catlettsburg, and same-day sampling is common.
Expect a visit fee and a per-sample cost, with rush lab processing billed on top. The written quote lists the expected sample count and the lab fees so the bill doesn't surprise you.
Proper gear means a calibrated pump, fresh spore-trap cassettes, tape and swab kits, and a cooler for transport. Results are only defensible with an AIHA-LAP accredited lab and a signed chain-of-custody form tracking each sample from collection to analysis.
Sampling methods
Each sampling method answers a specific question, so the dispatcher asks what you need the results for before routing your call.
The standard for airborne spores: a calibrated pump draws a measured volume through a cassette, and the lab reports counts per cubic meter by spore type, alongside the outdoor control.
For a visible stain, tape-lift and swab samples confirm whether it's fungal growth and identify it, while bulk samples handle porous materials.
A small hole and a short sample run can show whether a closed stud bay is full of spores. Cavity results aren't compared one-to-one with room air because cavities trap spores.
The ERMI test runs DNA analysis on a dust sample and scores the home against a national database. Treat it as a screen: it shows history in the dust, not what's airborne today, so most pros pair it with air samples.
After cleanup and before containment comes down, an independent pro pulls air samples inside the work area and outdoors to confirm the space is back to normal. The clearance report becomes the paperwork for disclosure forms, insurance and lease files.

How it works
Here's how a sampling job runs from the phone call to the lab report.
You'll be asked what the results are for, how many rooms are involved, and whether you need rush lab turnaround.
A local independent pro near Catlettsburg sets a time, often the same day for clearance or closing calls. Avoid running air purifiers or cleaning heavily right before the visit, since that skews the air sample.
On site, the pro checks the pump flow, runs the outdoor and indoor samples, and records times, volumes and locations. Any change to the sample count gets priced before it's taken.
Samples ship to an AIHA-LAP accredited lab under chain of custody, and results usually return in 24 to 72 hours with rush options.
From the dispatch log
These situations come through the line all the time.
A seller had a basement remediated and the buyer's agent asked for proof the job was finished. The sampling pro pulled air samples inside the work area and outdoors while containment was still up, plus a tape-lift from the cleaned framing. The accredited lab showed indoor counts below outdoor levels with a similar spore mix.
Outcome: The seller attached the lab report and chain-of-custody form to the disclosure, and the sale moved forward.
A parent called after a window leak soaked the carpet in a child's bedroom and wanted to know what was in the air. The pro took bedroom and hallway air samples plus an outdoor control. The bedroom showed elevated Penicillium and Aspergillus spores compared to outdoors.
Outcome: The results supported replacing the carpet pad, and the parent shared the report with the child's pediatrician.
A caller's store-bought petri dish grew several colonies, and they were sure the house was contaminated. The sampling pro explained that spores are always present in air, so a settle plate almost always grows something. Calibrated air samples with an outdoor control showed indoor counts well below outdoor counts.
Outcome: Real lab data replaced the dish result, and the homeowner skipped an unnecessary remediation estimate.
A tenant noticed a musty odor in a closet and the landlord said it was nothing. The tenant called for independent testing. The pro took a wall-cavity sample behind the closet, a room air sample and an outdoor control, all sent under chain of custody.
Outcome: The cavity sample showed high Stachybotrys counts, giving both sides lab data to work from.
These are composite examples based on common calls to the line, not individual customer reviews.
Questions
One call connects you with a local sampling pro in Catlettsburg who works with accredited labs.
Call +1-844-326-4757Petri dish settle plates aren't reliable for deciding anything. Since spores are always present indoors and out, a dish will grow colonies in nearly any house, and it gives no measured air volume and no outdoor comparison. For a real answer, you need a measured air sample and an outdoor control analyzed by an accredited lab.
Most labs return results within one to three business days of receiving the cassettes. Rush and same-day processing are usually available for an added fee, which helps when a closing or a containment teardown is waiting.
There's no federal numeric limit for indoor mold spores, so no single number makes a home safe or unsafe. Labs and assessors judge results by comparing indoor samples to the outdoor control and looking at which spore types dominate. People with asthma, allergies or immune concerns should go over the results with their doctor.
It sets the baseline everything else is measured against. Outdoor spore levels change with weather, season and time of day, so a sample taken during the same visit shows what normal looks like that day. Indoor air that exceeds the outdoor count or shows a different mix of species points to growth inside.
Partly. Spore-trap and tape-lift analysis under a microscope usually identifies mold to the genus level, such as Aspergillus, Penicillium, Cladosporium or Stachybotrys, but some spores look nearly identical and get grouped. Species-level identification requires culture or DNA methods, which cost more and take longer.
After remediation and before the plastic comes down, clearance samples verify that the work area air and surfaces are back to normal. You'll want it if you're selling, renting, filing an insurance claim, or if someone in the home is sensitive to mold. Use an independent tester, not the company that did the cleanup.

For clearance work, time the call so the samples are pulled while containment is still standing. For real estate or lease documentation, mention the deadline so rush lab options are discussed up front.
