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.
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 Berkeley 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.
Answered day and night, holidays too.

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.
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.

When you see something and want to know what it is, a surface sample answers that question directly.
Testers can sample inside a wall through a tiny hole, checking hidden spaces without demolition.
Clearance testing gives you proof the remediation worked before walls are closed up or tenants move back in.
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.
Tell us why you want testing: a smell, symptoms, a dispute, a sale, or clearance after removal. The goal decides which samples make sense.
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.
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. 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 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.
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.
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.
Homes, apartments, offices, and rentals across Berkeley can all be sampled through one 24/7 call.
