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 Markham 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.
Answered day and night, holidays too.

Sloppy sampling produces meaningless numbers. These are the standards we expect from the testers we refer.

Expect a calibrated pump, sealed sampling cassettes, and at least one outdoor baseline so indoor results mean something.
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.
The right test depends on what you're trying to prove. These are the common options.

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.
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.
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.

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.
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 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.
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.
