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 Occoquan 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.
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.
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.

Straightforward, start to finish.
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.
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.
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.
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.
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.
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.
