Vermiculite removal
Safe removal of loose-fill vermiculite insulation, which may contain asbestos, from attics and walls.
Why vermiculite is a problem
Vermiculite is a gold-brown or silvery granular insulation poured into many homes until the 1990s. Much of it came from a mine contaminated with asbestos. Health Canada advises not to disturb it and to have it removed by professionals.

Frequently asked questions
Does all vermiculite contain asbestos?
Not always, but testing is needed to rule it out. Until then, treat it as if it does.
Can I remove it myself?
No. Vacuuming or moving it releases fibres into the house. Removal must be done in a sealed area.
How can I recognize vermiculite?
It looks like small, light, shiny granules, grey-brown to gold, poured loose between the attic joists. Only a laboratory analysis can confirm whether it contains asbestos.
Does it absolutely have to be removed?
As long as it is not disturbed, the risk is low. Removal becomes necessary before work that affects the attic, ceilings or walls. It is also often requested when a property is sold.
How long does removal take?
For a residential attic, usually one to a few days, depending on the area and access.
