Why it fails in older and newer homes
Older homes: insulation may be decades old, compressed, damp or only partly installed. Newer homes: batts can fall when supports weren't installed well, or get pulled down during plumbing, cable or HVAC visits. In both, moisture from bare soil or torn plastic is a common culprit.
What replacement includes
- Removing and hauling away failed insulation
- Checking the framing
- Addressing moisture — often a new vapor barrier
- Installing new insulation, properly supported
Encapsulated crawl spaces
If you're considering encapsulation, the insulation plan may change — some encapsulated crawl spaces insulate the walls instead of the floor. Plan both together.
What affects the cost in Vancouver
- Floor area to insulate
- Removal and disposal of old material
- Obstructions like ducts and plumbing
- Moisture fixes
- Whether the crawl space is vented or encapsulated

Questions from Vancouver homeowners
My newer Vancouver home has fallen insulation. Why?
Usually missing or failed supports, moisture or disturbance from service work.
Floor insulation or wall insulation?
Floor insulation for a vented crawl space; wall insulation is an option in an encapsulated one. We'll set it up to match your crawl space.
