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 Duluth who gets you lab results you can stand behind.
Not every situation needs a lab. But when there's a dispute, a sale, or a health question, numbers from an accredited lab settle arguments that eyeballing can't.
Real people pick up 24/7.

Sloppy sampling produces meaningless numbers. These are the standards we expect from the testers we refer.

Expect a calibrated pump, sealed sampling cassettes, and at least one outdoor baseline so indoor results mean something.
Pricing is set per sample before the visit. No surprise lab charges after the results come back.
Calls are answered 24/7 and routed to a tester near Duluth. Standard lab results usually come back in two to three business days, with rush options available.
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.

When you see something and want to know what it is, a surface sample answers that question directly.
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.
Describe the situation and what you need to prove. That shapes the sampling plan.
A local tester arrives with calibrated equipment, takes an outdoor control, and samples the rooms or surfaces you're concerned about.
Samples go to an accredited lab. You already know the cost from the upfront quote, and you'll know when to expect results.
You get the lab report plus a plain-language explanation of what the numbers mean and whether remediation is recommended.

Here's what some recent callers shared.

My landlord kept saying the spots in my bedroom were just dirt. The lab confirmed two types of mold on the wall, 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. One wall cavity sample and an air test 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 tests tell you what you're breathing. Surface tests tell you what a visible stain actually is.
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.
Typically a few business days, with faster rush options when you're facing a closing date or move-in deadline.
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.
ERMI analyzes settled dust using DNA methods to identify mold species. It's sometimes used in health-related investigations, though most residential decisions rely on air and surface sampling.
