We keep crawl spaces dry with the right combination of interior drainage, a properly sized sump pump, and moisture control. Sometimes that pairs with a perimeter drain replacement on the outside; sometimes the interior system is what the site needs.
What a dry crawl space needs
Keeping a Victoria crawl space dry is rarely one product. It is a system matched to how water is getting in.
- Interior perimeter drainage to collect water that reaches under the house
- A sump pit and pump sized to move our winter water volume
- A vapour barrier over the soil to stop ground moisture rising
- Grading and outlet work so pumped water leaves the property properly
- Sealing obvious entry points where water and air get in
Signs your crawl space has a drainage problem
- Standing water or damp soil under the house after rain
- A musty smell rising into the ground-floor rooms
- Condensation or rust on ductwork, pipes, and metal connectors
- Mould or dark staining on joists and subfloor
- Cupping hardwood or cold, damp floors above the crawl space
How it connects to your perimeter drains
Interior crawl space drainage and exterior perimeter drains do different jobs. Perimeter drains stop water outside, before it reaches the foundation. A crawl space system manages water that is already getting under the house, or ground moisture rising from the soil. On many older Victoria homes the real fix is both: replace the failed exterior drains and add interior drainage plus a sump as backup.
Common questions
Do I need a sump pump in Victoria?
Many older Victoria homes do, especially where the water table is high or the lot sits low. A sump collects water that reaches under the house and pumps it away. We size the pump to our winter rainfall, not a dry-season guess.
Can a wet crawl space affect the rest of the house?
Yes. Moisture under the house rises into the floors and air above it, which can mean musty smells, mould, and rot in the structure. Drying the crawl space protects both the home and the air inside it.
Is a vapour barrier enough on its own?
A vapour barrier stops ground moisture rising, but it does not move liquid water that is already pooling. If water collects under the house you also need interior drainage and usually a sump. We match the fix to what is happening under your floor.
