Where is asbestos commonly found in older BC homes?

Asbestos is commonly found in floor tiles and vinyl flooring adhesive, ceiling tiles, popcorn or textured ceiling spray, joint compound and drywall tape, pipe insulation, boiler and furnace insulation, attic insulation (vermiculite), roof shingles, exterior siding (transite panels), window glazing and caulking, duct wrapping, spray-applied fireproofing, and plaster and stucco finishes.

Can you tell if a material contains asbestos by looking at it?

No. You cannot identify asbestos by sight alone. Only certified laboratory analysis can confirm whether a material contains asbestos. When in doubt, test before you touch it.

What should I do if I suspect a material in my home contains asbestos?

Do not disturb the material. Even small disturbances can release dangerous airborne fibres. Contact Guardian Laboratories for a professional inspection. Our Level S certified surveyors will safely assess, sample, and report on any suspected asbestos-containing materials.

Q: Is asbestos testing required by law in BC before renovating?

Yes. Under WorkSafe BC regulations, asbestos testing is legally required before any renovation or demolition of buildings constructed prior to 1990. Non-compliance can result in serious fines and project shutdowns.

Residential Asbestos Testing

Your home and workplace should be places of comfort and confidence — not uncertainty. We provide professional asbestos testing across Southern Vancouver Island and the Gulf Islands, delivering clarity when it matters most.

Our inspections are performed in full accordance with provincial regulations, ensuring your project moves forward safely and compliantly. If your building was constructed before the 1990s, asbestos testing is required prior to any renovation or disturbance. Taking this step early protects both your health and your investment.

When disturbed, asbestos fibres can linger in the air for hours — even days. Exposure carries serious, irreversible health risks. That's why careful planning and accurate testing are essential.

Before reaching out, we encourage you to review your renovation plans to identify the materials involved. A little preparation allows us to provide precise guidance and the exact testing you need — saving you time while ensuring nothing is overlooked.

⚠ Health Risk — Do Not Disturb

If you suspect a material contains asbestos, do not disturb it until it has been tested. Even small disturbances can release fibres. Asbestos exposure is linked to:

Mesothelioma (lung lining cancer)
Asbestosis (lung scarring)
Lung cancer
Pleural disease

⚠ BC Regulation Requirement

Under WorkSafe BC regulations, asbestos testing is legally required before any renovation or demolition of buildings constructed prior to 1990. Non-compliance can result in serious fines and project shutdowns.

Preparation Tips

How to Prepare Before Calling

The more information you have ready, the faster we can recommend the right inspection and get it booked.

1

Know Your Building Age

Find out when your building was constructed. Buildings built before 1990 are most likely to contain asbestos materials. The exact year helps us determine the likelihood and scope of any asbestos presence.

2

Identify Your Renovation Scope

Write down which areas and materials will be disturbed during your renovation. The more specific you can be (e.g., "removing 200 sq ft of vinyl flooring in the kitchen"), the more accurate your quote will be.

3

Note Visible Damage or Deterioration

Take note of any materials that appear damaged, crumbly, or deteriorating. Friable (crumbly) materials are a higher priority and may require more urgent attention even before renovation begins.

4

Plan for Access

Our inspector will need access to all areas being tested, including attics, crawlspaces, and mechanical rooms. If these areas are locked or difficult to reach, let us know in advance so we can plan accordingly.

What to Tell Us When You Call

Having this information ready will help us match you with the right inspection type and provide an accurate quote:

Year of construction (approximate is fine)
Type of property (home, strata, commercial)
What work is planned and which materials
Size of the area being worked on
Whether any materials appear damaged
Your desired timeline / project start date
Whether rush results may be needed

DIY Sampling Option

For basic testing on easily accessible materials, we offer a guided at-home sampling option. You collect the sample following our safe protocol, and we analyze it in our certified lab.
