Indoor air sampling
A pump draws a measured volume of air, often about 15 liters per minute for five to ten minutes, through a spore trap cassette. The lab counts and identifies spores per cubic meter.
Whether you're dealing with a landlord, a home sale, or a family member who feels worse indoors, call Breffni Remediation. We'll connect you with an independent mold tester in Arden-Arcade who gets you lab results you can stand behind.
Testing is most useful when the mold is hidden, when someone needs documentation, or when you want proof a remediation job actually worked. A good tester will tell you when it isn't worth the money.
Real people pick up 24/7.

Testing only helps if it's done right and interpreted honestly. Here's what you can expect.

Testers use calibrated air pumps with spore trap cassettes, sterile swabs, and tape-lift slides, and always pull an outdoor control sample for comparison.
Pricing is set per sample before the visit. No surprise lab charges after the results come back.
Local testers schedule quickly, and many labs offer next-day or 24-hour rush analysis when a deadline is close.
Testers in our network carry their own insurance and any licensing your area requires. Ask whether samples go to an AIHA-accredited lab; good testers say yes without hesitating.
The right test depends on what you're trying to prove. These are the common options.
A pump draws a measured volume of air, often about 15 liters per minute for five to ten minutes, through a spore trap cassette. The lab counts and identifies spores per cubic meter.
Clear tape or a sterile swab picks up material from a suspicious stain so the lab can confirm whether it's mold and which genus it is.
A small port lets the tester sample air inside a wall without opening it, which is useful when you suspect growth behind finished drywall after a leak.
After removal, air samples inside the former work area should come back in line with outdoor levels, without elevated indicator types like Stachybotrys or Chaetomium. This is how you know the job is done.
When two sides disagree about mold, accredited lab results with proper paperwork are hard to argue with.

Here's what happens after you call.
Tell us why you want testing: a smell, symptoms, a dispute, a sale, or clearance after removal. The goal decides which samples make sense.
A local tester arrives with calibrated equipment, takes an outdoor control, and samples the rooms or surfaces you're concerned about.

Here's what some recent callers shared.

My landlord kept saying the spots in my bedroom were just dirt. The tape-lift came back as Cladosporium and Aspergillus, and the air sample was well above outdoor levels. That report got the repair done.
After paying for remediation, I wanted proof. The clearance air samples came back lower than the outdoor control, and I finally felt comfortable moving my kids back into the basement.
We were selling and the buyer asked about a past leak. A quick cavity sample plus air testing showed nothing unusual, and the deal closed on time.
He walked me through every number on the report instead of just emailing a PDF. Knowing what was normal versus elevated made the whole thing less stressful.
Air sampling measures spores floating in a room compared with outdoor air. Surface sampling identifies what's growing on a specific spot. Many situations call for one or the other, not both.
Mold spores are always present outdoors. The outdoor control sets a baseline, so indoor results can be judged by whether they're higher or contain different types than outside.
Standard lab turnaround is usually two to three business days. Many labs offer 24-hour or same-day rush analysis for an added fee.
Not very. Petri-dish kits grow mold in nearly every home, which tells you little. Professional sampling measures volume and compares indoor to outdoor air.
No official threshold exists. Testers look at how indoor counts and types compare to outdoor air on the same day.
It's a DNA-based dust test that identifies many mold species. Ask your tester whether it fits your situation, since it isn't always necessary.
