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 Rohnert Park 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.

Testers use calibrated air pumps with spore trap cassettes, sterile swabs, and tape-lift slides, and always pull an outdoor control sample for comparison.
You'll know the cost per sample and the lab fee before anything is collected, so you can choose how many locations to test.
Calls are answered 24/7 and routed to a tester near Rohnert Park. 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.
Different questions call for different samples. Here's what testers in our network typically offer.

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.
Testers can sample inside a wall through a tiny hole, checking hidden spaces without demolition.
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.
Lab reports with chain-of-custody records give buyers, sellers, tenants, and landlords objective evidence instead of competing opinions.

Here's what happens after you call.
Describe the situation and what you need to prove. That shapes the sampling plan.
Samples are collected indoors and out, sealed, labeled, and logged on a chain-of-custody form.
The lab analyzes the samples on a standard or rush schedule, at the price you agreed to before the visit.
You get the lab report plus a plain-language explanation of what the numbers mean and whether remediation is recommended.

A few recent testing jobs, in customers' own words.

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.
I wanted proof the remediation actually worked. 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.
The tester explained the numbers clearly 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.
Without an outdoor baseline, indoor numbers have nothing to be compared against. It's what makes the results meaningful.
Standard lab turnaround is usually two to three business days. Many labs offer 24-hour or same-day rush analysis for an added fee.
Settle-plate kits from the hardware store almost always grow something because spores are everywhere. Without an outdoor control or measured air volume, the results can't tell you much.
There are no federal limits for indoor mold spores. Results are judged by comparing indoor samples with outdoor controls and looking for water-damage indicator species.
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.
