If you live in Mission and own or rent an older home, knowing how to check for asbestos in your house is one of the most important safety steps you can take. Asbestos was widely used in residential construction before the 1980s, and homes in Mission are no exception. This guide walks you through everything — from identifying risk areas to hiring a certified inspector.
What Is Asbestos and Why Is It Dangerous?
Asbestos is a naturally occurring mineral fiber that was extensively used in construction materials throughout the 20th century. Its fire-resistant and insulating properties made it a popular additive in everything from floor tiles to pipe insulation. However, when asbestos-containing materials are disturbed, they release microscopic fibers into the air that, when inhaled, can cause serious and life-threatening illnesses.
The health risks associated with asbestos exposure include:
- Mesothelioma — a rare but aggressive cancer of the lining of the lungs
- Lung cancer — especially in people who also smoke
- Asbestosis — chronic lung scarring that impairs breathing
- Pleural disease — thickening and scarring of the lung lining
There is no safe level of asbestos exposure. Symptoms can take 20–50 years to appear, which is why acting proactively — especially in older Mission homes — is critical.

Is Your Mission Home at Risk?
Mission, BC, has a significant stock of homes built before the 1990s. If your property was constructed or renovated between 1920 and 1990, there is a real possibility that asbestos-containing materials (ACMs) are present somewhere in the structure.
Key risk factors include:
- Home built or renovated before 1990
- Original flooring, ceiling tiles, or textured paint still in place
- Older HVAC ducts with visible insulation wrap
- A furnace or hot water boiler installed before the mid-1980s
- Exterior siding made of fiber cement panels
- Popcorn or stippled ceilings
Even if your home was built in the 1990s, materials sourced during construction could have contained residual asbestos. When in doubt, checking for asbestos in your Mission house is always the safer choice.
Where Asbestos Hides in a House
Asbestos was used in dozens of building materials. Knowing the common locations helps you assess your home intelligently before calling in a professional.
High-risk areas
- Popcorn / stippled ceilings
- Vinyl floor tiles and backing
- Pipe and duct insulation
- Attic insulation (vermiculite)
- Furnace and boiler insulation
- Roof shingles and felt underlay
Moderate-risk areas
- Drywall joint compound
- Textured wall paint
- Exterior fiber cement siding
- Window putty and caulking
- Electrical panel backing boards
- Garage and shed walls
Vermiculite Insulation — A Special Warning
Vermiculite attic insulation deserves special mention. Much of the vermiculite sold in North America before 1990 came from the Libby, Montana mine — a source heavily contaminated with tremolite asbestos. If your Mission home has loose, pebble-like gray or silver insulation in the attic, treat it as asbestos-containing and do not disturb it under any circumstances.
How to Check for Asbestos in Your House in Mission (Step-by-Step)
The safest and most reliable way to check for asbestos in your house in Mission involves a combination of visual inspection and certified laboratory testing. Here is a practical step-by-step process:
If you are not confident in your ability to safely collect a sample without disturbing the surrounding material, skip DIY sampling entirely and hire a certified asbestos inspector. The cost of a professional inspection is far less than the health risk of improper sampling.
What Does “Friable” Mean?
During your visual inspection, pay close attention to the condition of materials. Friable asbestos is material that can be crumbled or reduced to powder by hand pressure — it is the most dangerous type because it releases fibers easily. Non-friable asbestos is bound within a solid matrix (like vinyl floor tiles) and poses much lower risk unless cut or sanded.
Prioritize testing friable or damaged materials first when checking for asbestos in your Mission house.
DIY vs. Professional Asbestos Testing
Homeowners in Mission have two main testing options. Understanding the pros and cons of each helps you make the right decision for your situation.
DIY testing kit
- Cost: $30–$80 (kit + lab fee)
- You collect the sample yourself
- Risk of improper sampling technique
- Good for a single known material
- Results in 3–7 days
- No site assessment included
Professional inspection
- Cost: $400–$1,200+
- Comprehensive whole-home survey
- Certified hygienist collects samples safely
- Includes written assessment report
- Required before major renovations in BC
- Legally defensible documentation
Recommendation: For routine peace of mind with one or two suspected materials, a DIY kit is acceptable. For any planned renovation, sale of the property, or if multiple suspect materials exist throughout the home, a professional inspection is strongly advised — and in many cases legally required under WorkSafeBC regulations.

What Happens During a Professional Asbestos Inspection in Mission
If you hire a certified asbestos inspector to check your Mission house, here is what to expect during the process:
- Pre-inspection interview: The inspector will ask about the age of the home, any known renovations, and areas of concern you have identified.
- Visual walkthrough: A thorough examination of all accessible areas, including the attic, crawl space, basement, and mechanical room.
- Material sampling: Bulk samples are collected from suspect materials using proper PPE and containment procedures. Typically 3–5 samples per material type.
- Lab analysis: Samples are sent to an accredited lab for polarized light microscopy (PLM) analysis — the industry standard for asbestos identification.
- Written report: A detailed report identifying the location, type, condition, and risk level of any ACMs found, along with recommended action.
What to Do If Asbestos Is Found
Discovering asbestos in your Mission home is not a reason to panic. The key is responding appropriately based on the condition and location of the material.
Leave it alone (encapsulation / management)
If the asbestos-containing material is in good condition and will not be disturbed by day-to-day activities, the safest approach is often to leave it in place and monitor it. This is known as asbestos management. You should seal or encapsulate the material and document its location for any future contractors or buyers.
Abatement (removal)
Removal is necessary when:
- The material is heavily damaged or friable
- You are planning a renovation that would disturb the area
- The material is in a high-traffic area prone to damage
- You are selling the property and disclosure requires it
In Mission and throughout BC, asbestos abatement must be performed by a WorkSafeBC-registered contractor. Never attempt to remove asbestos yourself — improper removal is illegal and creates serious health risks for you and your neighbours.
