How It Works
Turn a damp, musty crawl space into a clean, dry, sealed area with encapsulation, drainage and moisture repair. Our team inspects your home first, then recommends only what your basement actually needs.
- Full crawl space encapsulation with reinforced liners
- Perimeter drainage and sump for standing water
- Sealing of vents, rim joists and openings
- Dehumidification to keep humidity in check
Why Calgary basements need it
Expansive clay soil, fast chinook melts and intense summer storms put pressure on basement walls and floors. A managed drainage path relieves that pressure and keeps water off your floor.

Common Questions
How long does installation take?
Most residential projects take 1–3 days, depending on basement size and access.
Is it messy?
We protect your floors, contain dust and clean up daily.
Is there a warranty?
Yes. Our crawl space liner carries a transferable 25-year warranty: no charge to repair tears or holes in the liner unless caused by abuse or misuse. Condensation, frozen discharge lines and pre-existing wood damage are not covered. See your written contract for full terms.
