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 Walnut Creek 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.

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.
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.
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.

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.
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.
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.
The tester walks you through the results, compares indoor and outdoor counts, and gives a clear recommendation.

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.
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. 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 tests tell you what you're breathing. Surface tests tell you what a visible stain actually is.
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.
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.
