Lab numbers, not guesswork
If a buyer, a landlord or a doctor wants numbers, you need samples run by an accredited lab. One call connects you with a licensed independent sampling pro near Spartanburg who collects spore-trap air samples and surface samples and sends them to an accredited lab.
ESS Mold Inspection is a free referral service. Samples are collected by independent local professionals and analyzed by third-party labs.
How sampling works
Mold testing is lab science. 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.
Surface sampling answers a different question: what is this stain? 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 Spartanburg 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.
Sampling pros in the network are independent, insured, and licensed where a state requires a license for mold assessment. Because they aren't selling the remediation, they have no reason to steer results.
Clearance tests often hold up a containment teardown or a closing, so timing matters. Tell the dispatcher it's a clearance or a closing, and the call is routed to a Spartanburg pro who can sample soon; same-day is common.
Expect a visit fee and a per-sample cost, with rush lab processing billed on top. You get that breakdown in writing before anyone shows up, including how many samples the pro expects to take.
Proper gear means a calibrated pump, fresh spore-trap cassettes, tape and swab kits, and a cooler for transport. Every sample goes to an AIHA-LAP accredited lab with a chain-of-custody form showing who handled it and when.
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.
When there's a visible spot, a tape-lift or swab tells you whether it's actually mold and which genus it is, and a bulk sample works for porous material like carpet backing or insulation.
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.
ERMI uses DNA analysis on settled dust to identify 36 mold species and produce an index score. It's useful as a screening tool, but it reflects dust that may have collected over years, not current air conditions, and it isn't a substitute for air sampling.
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. Sellers and landlords often need that lab report for real estate disclosures or lease records.

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 Spartanburg sets a time, often the same day for clearance or closing calls. Keep windows closed and skip the vacuuming for a day beforehand so the air reflects normal conditions.
The pro confirms the sample plan, calibrates the pump, pulls the outdoor control and the indoor samples, and labels each cassette. Extra cassettes are only added once you approve the price.
The lab typically turns results around in one to three days, faster with rush service, and the pro walks you through the report.
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 homeowner left an open settle plate on the kitchen counter for an hour, saw fuzzy growth days later and called in a panic. 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.

Call +1-844-326-4757Not in any useful way. Mold spores float in every home and every backyard, so leaving a dish open almost always grows something, and the kit can't tell you how much is in the air compared to outside. For a real answer, you need a measured air sample and an outdoor control analyzed by an accredited lab.
Standard turnaround at most accredited labs is 24 to 72 hours after the lab receives the samples. 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. Results are read against the outdoor baseline and by spore type, not against a fixed threshold. 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.
To a degree, yes. 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.
