Indoor air sampling
Air samples show what's floating in the room right now. Each indoor result is compared against an outdoor sample taken the same day.
Need proof, not guesses? Breffni Remediation connects you with licensed and insured independent mold testing professionals in San Anselmo who collect air and surface samples, send them to an accredited lab, and explain the results in plain English.
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.
Insurance, licensing where required, and accredited lab partners are the baseline we look for in every independent tester.
Different questions call for different samples. Here's what testers in our network typically offer.
Air samples show what's floating in the room right now. Each indoor result is compared against an outdoor sample taken the same day.
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.
When two sides disagree about mold, accredited lab results with proper paperwork are hard to argue with.

Straightforward, start to finish.
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.
The lab analyzes the samples on a standard or rush schedule, at the price you agreed to before the visit.
The tester walks you through the results, compares indoor and outdoor counts, and gives a clear recommendation.

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.
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.
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.
Typically a few business days, with faster rush options when you're facing a closing date or move-in deadline.
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.
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.
