Vermiculite Testing Calgary
Specialized testing for vermiculite insulation, which often contains asbestos from the Libby, Montana mine. Essential before any attic work in Calgary homes built before 1990.
What is Vermiculite Insulation?
Vermiculite is a naturally occurring mineral that expands when heated, creating a lightweight, pebble-like insulation material. It was widely used in attics across North America from the 1920s through the early 1990s due to its excellent insulating properties and fire resistance.
The most common brand was Zonolite, manufactured by W.R. Grace and Company. Unfortunately, much of the vermiculite used in North America came from a contaminated mine in Libby, Montana, which also contained asbestos deposits.
It's estimated that 70-80% of vermiculite insulation found in homes contains some level of asbestos contamination. This makes testing essential before any attic work or disturbance.
How to Identify Vermiculite
- • Light, pebble-like texture
- • Silver-gold or gray-brown color
- • Accordion-like flakes
- • Poured loose-fill insulation
- • Common in older attics
- • Often 2-6 inches deep
If you see this type of insulation in your attic, do not disturb it until testing confirms asbestos status.
Critical Safety Warning
Never disturb, vacuum, or attempt to remove vermiculite insulation yourself. Any disturbance can release asbestos fibers into the air, contaminating your entire home and exposing your family to serious health risks. Always hire certified professionals for vermiculite work.

What if Asbestos is Detected?
Leave in Place
If undisturbed and in good condition, vermiculite can often be left in place safely.
- • Seal attic access points
- • Limit attic access
- • Inform contractors
- • Document for future owners
- • Monitor condition
Encapsulation
Cover vermiculite with new insulation to prevent fiber release.
- • Less expensive than removal
- • Improves energy efficiency
- • Reduces exposure risk
- • Professional installation required
- • Still requires monitoring
Professional Removal
Complete removal eliminates the asbestos risk permanently.
- • Permanent solution
- • Increases property value
- • Allows safe attic access
- • Enables renovations
- • Peace of mind
Our Recommendation
We provide objective recommendations based on your specific situation, including the asbestos content, your plans for the property, and your budget. There's no one-size-fits-all answer, and we'll help you make the best decision for your family and property.
Vermiculite Removal Services
If removal is recommended or desired, we provide complete vermiculite abatement services following the same rigorous safety protocols as other asbestos removal projects. Vermiculite removal is specialized work due to the loose-fill nature of the material and its tendency to settle into every crevice of your attic.
Our Removal Process Includes:
- Complete attic containment with heavy barriers
- Negative air pressure with HEPA filtration
- Careful vacuum removal of all vermiculite
- HEPA vacuuming of all attic surfaces
After Removal:
- Air clearance testing verification
- Safe disposal at approved facilities
- New insulation installation available
- Complete documentation and certificates
Project Timeline
Typical vermiculite removal timelines:
- • Testing to results: 3-5 days
- • Small attic removal: 2-3 days
- • Large attic removal: 4-7 days
- • Clearance testing: 1-2 days
- • Total project: 1-2 weeks
Investment Factors
Removal costs depend on:
- • Attic square footage
- • Insulation depth and volume
- • Attic accessibility
- • Complexity of attic layout
- • Required clearance testing

Frequently Asked Questions
How do I know if I have vermiculite insulation?
Look in your attic for pebble-like, lightweight insulation with a silver-gold or gray-brown color. It looks like small accordion-shaped flakes. Common brand names include Zonolite. If you're unsure, we can inspect your attic and confirm. Never disturb suspected vermiculite for closer inspection.
Does all vermiculite contain asbestos?
No, but an estimated 70-80% of vermiculite insulation in North American homes contains asbestos because most came from the contaminated Libby, Montana mine. The only way to know for certain is through laboratory testing. We always recommend testing rather than assuming it's safe.
Can I use my attic if it has vermiculite?
If the vermiculite is undisturbed and you avoid walking on it or creating air movement, the risk is minimal. However, you should avoid storing items, running new wiring, or doing any work that disturbs the insulation. Any attic work requires professional testing first.
How much does vermiculite testing cost?
Testing typically costs $200-$400 depending on your location and how many samples are needed. This is a small investment compared to the health risks of asbestos exposure or the cost of improper handling. We provide free quotes over the phone.
Is vermiculite removal covered by insurance?
Most insurance policies don't cover vermiculite removal as it's considered a pre-existing condition and maintenance issue. However, if removal becomes necessary due to damage from a covered event (like water damage), you may have coverage. Check with your insurance provider and we can provide documentation to support any claims.
