The types of materials in your home that may contain asbestos are listed below:

  • Flooring: Vinyl tiles, Linoleum sheet flooring, and flooring adhesives.
  • Drywall joint compound.
  • Window and door caulking.
  • Textured or stipple-coated walls and ceilings.
  • Plaster and stucco (interior and exterior).
  • Cement board siding and under sheeting.
  • Acoustic ceiling tiles.

Yes, you can drop off bulk material samples for asbestos analysis between the hours of 08:00 and 16:30, Monday to Friday. We are located at 1636 12 Avenue SW, Calgary. We recommend you call our office prior to drop off to ensure we have a technician available. Each sample must be submitted separately in a sealed plastic bag.

We can do rush, next business day by 15:00, or 5-day turn around time for results. We ask that you submit your sample no later than 13:00. If you submit your rush sample after this time, we cannot guarantee rush results.

Yes, vinyl floor tiles require 2-days for results due to a longer process for breaking down the material.

Drywall itself does not contain asbestos, but the drywall joint compound or mud, does. We recommend taking the sample in corners or on edges where you would expect to find drywall joint compound.

Vermiculite insulation can be described as small, silver-grey shiny chips. Many have said that is resembles kitty litter. For accurate results we recommend filling a large freezer size zip lock bag for analysis. Please note when collecting the vermiculite sample to collect the sample close to the bottom as this is where the asbestos dust will settle.

To minimize the release of asbestos fibres when collecting a sample we recommend spraying the material with water. We recommend wearing disposable gloves when collecting the sample. Once the sample has been collected, the impacted material should be covered with tape to prevent the release of fibres. Make sure to wash your hands thoroughly after collecting the sample.

When it comes to mould investigations there are a couple of options available for the investigation of suspected contaminated materials. A basic mould investigation or an intrusive mould investigation can be conducted, with a report detailing the findings and recommendations for remediation and corrective actions following the completion of the assessment.

A basic mould investigation typically includes:

  • A visual inspection of affected areas;
  • Non-destructive testing of selected materials for moisture using a moisture meter and/or infrared camera;
  • Review of building history for water intrusion event(s);
  • Collection of bulk mould samples from surfaces to determine if mould is present and to identify the type and relative quantity; and
  • Collection of air samples for spore analysis.

An intrusive mould investigation includes everything mentioned for a basic mould investigation in addition to:

  • An intrusive investigation into hidden wall cavities and surfaces by cutting access holes into walls and ceilings, lifting carpets or other flooring.
