Where do I find asbestos? What/where should I sample?

Here are the most common places you’ll find asbestos. Your sample only needs to be the size of a dime:

  • Drywall mudding compound
  • Vinyl floor tiles (VCT floor tiles)
  • Linoleum flooring
  • Silicone around windows/sliding doors
  • Textured popcorn ceiling
  • Textured walls
  • Plaster
  • Attic/wall insulation
  • Roofing materials

To avoid making a mess, plan before taking each sample. Luckily, we’ve put together details for each of the above locations in our Asbestos Sampling Guide.

How much air volume do I need to push through my cassette to get a proper sample reading?

You’ll need 2,400 litres for a clearance test, and 480 litres for personal air monitoring.

In order to get an accurate reading, you’ll want between 1000-1,300 fibre count density.

Learn how to do air sampling in our Asbestos Sampling Guide.

Air tests should be performed by a trained PCM technician (phase contrast microscopy, NIOSH 582 equivalent qualification).

What size should my bulk sample be?

A bulk (solid) sample just needs to be roughly the size of a dime.

Does Asbestos Grow?

No. Asbestos is an inorganic mineral. By that definition, it doesn’t grow.



How do I collect an air sample?

The simple steps to collecting an air sample are:

  1. Run your air pump with the cassette inside. You’ll need 2,400 litres for a clearance test, and 480 litres for personal air monitoring.
  2. Remove the cassette from the pump. Place it in a ziplock bag and label it
  3. Label the ziplock bag. (ex: “A1 = living room ceiling – popcorn ceiling”).
  4. Place all ziplock bags in one larger Ziploc bag and write the address location.

How do I submit a sample?

Collect your sample in a Ziploc bag, known as the “collection media.”

Don’t cross-contaminate your bulk and air samples. Using separate bags to collect individual samples is the best way to keep them from cross-contamination.

Once you’ve collected the samples, bring them into the lab. You can fill out your chain of custody form before you come, or we can help you fill it out in person.

When we’re done testing, your sample is stored on file until it expires. Once expired, we’ll safely dispose of your sample.

You don’t even have to drop the sample off in person. We have 6 different ways for you to submit your sample to us.

What is the cost for samples?

Pricing for samples depends on:

  • turnaround times and
  • the type of sample needed

As long as you have a chain of custody form filled out, we don’t need any more information about your sample.

Please give us a call for specific pricing details!

Will you come collect my sample for me?


For anyone within the GTA (Greater Toronto Area), we will send a professional to pick-up your sample, drop it at the lab, and deliver the results to you. No effort on your part required.

If you’re outside the GTA, call us. For an additional fee (for travel expenses) we’ll travel almost anywhere within reason.

Our 6 delivery options are designed to save you time so you can spend less time transporting samples, and more time writing DSS reports.

What is your “Automatic Sampling” service?

We realize that it might be hard to coordinate the sample delivery. You have to take the sample, deliver it to the lab, and everything in between (drive-times, traffic, etc.).

That’s why we offer automatic sampling. Simply call us, tell us where to go, and we will send a professional out to:

  • take the sample
  • bring it back to the lab
  • deliver you the sample test results via phone, FAX or email

You don’t have to do a single thing.

In the Greater Toronto Area (GTA) the cost for this service is $250 for the 1st sample and $150 for each additional sample. Within 24 hours you’ll have your results.

Call us for bulk pricing or quicker turnaround times on our automatic sampling service.

Our 6 delivery options are designed to save you time so you can spend less time transporting samples, and more time writing DSS reports.

Where do I buy pumps & supplies?

We can supply any pumps or equipment needed for bulk and air sampling.

For bulk sampling, you’ll want a bulk sampling kit which has everything you need to take and store your bulk samples. We have an easy-to-use bulk sampling tool that allows you to take a sample with only a hammer.

For air sampling, we offer pumps, cassettes, and air sampling kits.

Call us or come in and you can get whatever supplies you need from us.

What Is Asbestos?

Asbestos is a silicate material naturally occurring in the environment. It was used during the early 20th-century in construction material because of its light, strong, and fire-retardant properties.

Asbestos contains microfibres which pose a grave health risk to those subject to prolonged exposure. When inhaled, the fibres attach to the lungs, damaging tissue and causing a life-threatening disease called Asbestosis.
