How to Detect Asbestos, Lead Paint, or Mold in Older Metro Vancouver Buildings
Before beginning any demolition or renovation in Metro Vancouver, one crucial question should guide your planning:
Does the building contain asbestos, lead-based paint, or mold?
Structures built before the 1990s often do—and disturbing these materials without proper identification and removal can expose occupants and workers to serious health risks, project delays, and legal consequences.
At Rhino Demolition & Disposal Services, we specialize in asbestos, lead, and mold detection and abatement throughout Metro Vancouver. This guide explains how to spot the signs and take action safely.
Why Asbestos, Lead, and Mold Detection Matters in Metro Vancouver
Identifying hazardous materials isn’t just about compliance—it’s about protecting lives.
- Asbestos exposure causes diseases like mesothelioma and asbestosis.
- Lead affects the brain and nervous system, especially in young children.
- Mold can trigger chronic respiratory illnesses and allergic reactions.
If your building was constructed prior to 1990, it may contain one or more of these materials. Under WorkSafeBC regulations, a Hazardous Materials Survey is mandatory before any work that disturbs building components.
Signs Your Building May Contain Asbestos
Asbestos was commonly used until the early 1990s. It’s invisible to the naked eye and requires professional sampling for confirmation.
Common Asbestos-Containing Materials
| Material | Location |
|---|---|
| Drywall mud and plaster | Interior walls, ceilings |
| Floor tiles and vinyl | Kitchens, bathrooms |
| Pipe insulation | Basements, mechanical rooms |
| Popcorn ceiling | Bedrooms, living areas |
| Roofing felt, shingles | Attics, roofs |
| Cement siding | Exterior walls |
Indicators of Asbestos:
- Home or building built before 1990
- Crumbly pipe insulation
- Textured ceilings (e.g., popcorn ceilings)
Important: Do not touch or remove suspected materials. Contact a certified hazmat contractor to conduct a Hazardous Materials Survey.
How to Identify Lead-Based Paint in Metro Vancouver Homes
Lead-based paint was banned for residential use in Canada in 1976, but many homes and schools built earlier still contain it.
Lead Paint Warning Signs:
- Peeling, flaking, or “alligatoring” paint
- Dust from old painted surfaces
- Thick paint layers on wooden trim or windows
- Structures built before 1978
Health Impacts of Lead Exposure:
- Children: Behavioral issues, learning difficulties, neurological damage
- Adults: Hypertension, kidney damage, reproductive problems
Certified professionals use XRF scanners or send samples to accredited labs for analysis. If lead is detected, professional removal or encapsulation is required to meet safety standards.
Detecting Hidden Mold in Metro Vancouver Buildings
Mold thrives in damp, dark, and poorly ventilated areas. It’s often hidden behind walls or under floors, making early detection crucial.
Signs of Mold:
- Persistent musty or earthy smell
- Peeling paint or bubbling drywall
- Black, green, or white patches
- Condensation or cold spots on walls
Common Mold Hotspots:
- Crawlspaces and basements
- Behind drywall in bathrooms
- Around leaky pipes or windows
- Attics with poor ventilation
Mold Exposure Risks:
- Chronic coughing, sneezing
- Asthma attacks
- Respiratory infections
- Eye and skin irritation
Remediation tip: Spraying bleach won’t eliminate the problem. Professional mold remediation involves isolating the source of moisture, containing the spread, and using HEPA vacuums and air scrubbers.
When Should You Get a Hazmat Survey?
If your building in Metro Vancouver was constructed before 1990, and you’re planning to:
- Renovate or demolish
- Replace plumbing, flooring, or walls
- Remove popcorn ceilings
- Upgrade insulation
…then a Hazardous Materials Survey is legally required under WorkSafeBC.

FAQs
What is a hazardous materials survey in Metro Vancouver?
A hazardous materials survey identifies asbestos, lead, mold, or other harmful substances in a building before demolition or renovation. It is required by WorkSafeBC for any structure built before 1990.
How do I know if my home has asbestos or lead paint?
If your home was built before 1990, it may contain asbestos in insulation or floor tiles, and lead paint on doors and trim. Only professional lab testing can confirm it.
Can mold be removed without professional help?
No. Mold remediation requires source moisture detection, containment, and air purification. DIY methods often fail to fully remove the spores and can make the problem worse.
