Lab numbers, not guesswork
When you need actual data on what's in the air, a swab from a hardware store kit won't cut it. The dispatcher routes you to an independent, insured tester in Shannon who sets up the pump, logs the volume and gets the cassettes to a lab the same day when possible.
ESS Mold Inspection is a free referral service. Samples are collected by independent local professionals and analyzed by third-party labs.
How sampling works
Testing means collecting physical samples and handing them to a microbiology lab. For air, the sampling pro attaches a sealed spore-trap cassette to a pump calibrated with a rotameter, then runs it at a set flow rate, often 15 liters per minute for 5 minutes, which pulls 75 liters of air across a sticky slide. The lab counts and identifies what landed on that strip under a microscope, then converts the count to spores per cubic meter of air.
Indoor numbers mean almost nothing on their own. Outdoor air always carries spores, which is why a control sample gets taken outside during the same visit. 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. Tape-lifts grab spores and hyphae from smooth surfaces, swabs handle textured spots, and bulk samples are small cut pieces of the material itself. A wall-cavity air sample, drawn through a tiny hole, can show whether a closed cavity is loaded with spores. Most Shannon callers want testing for paperwork: a real estate disclosure, a tenant complaint, or proof a cleanup worked.
What separates good sampling
Lab results are only as reliable as the way the samples were collected, handled and shipped.
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.
When a remediator is waiting on clearance before pulling the plastic, a slow tester costs you days. Tell the dispatcher it's a clearance or a closing, and the call is routed to a Shannon pro who can sample soon; same-day is common.
Testing is usually priced as a site fee plus a per-sample lab charge, and rush turnaround costs extra. 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
The right test depends on what decision you're trying to make, so be ready to say whether it's for a sale, a lease or a clearance.
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. Results are read differently from room air, since cavities are closed spaces.
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 Shannon 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.
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.
The buyer wanted documentation after a seller's basement cleanup, and the seller called the line. 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.
After a leaking window wet the bedroom carpet, a parent wanted lab data before letting the child sleep there again. 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 renter and a property manager disagreed about whether a closet smell needed attention. 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 Shannon 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. A calibrated pump sample with an outdoor control is what labs and real estate agents in Shannon actually accept.
Standard turnaround at most accredited labs is 24 to 72 hours after the lab receives the samples. If a deadline is close, ask about rush service when you book, since it costs more but can cut the wait to hours.
No federal agency sets a safe indoor spore count. 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. Microscope work on air and tape samples identifies most spores by genus, though look-alike types like Aspergillus and Penicillium are often reported together. 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.
Service area
The line routes sampling calls across Shannon, from single-family homes and rentals to condos and small offices. Your call goes to a licensed, independent pro close by who sends samples to an accredited lab and can work around your deadline.
If you need clearance, call once the remediator finishes, before containment comes down. For real estate or lease documentation, mention the deadline so rush lab options are discussed up front.
