Vancouver Basement Waterproofing Cost Calculator & 2026 Repair Prices
Published local prices vary because a pump replacement, a crack injection, and a full drainage system solve different problems. Use these source-attributed ranges to set a budget—not as a substitute for an on-site diagnosis.
Request Local QuotesHow to read the numbers
All amounts are CAD, before tax unless a source states otherwise. They summarize publicly posted Greater Vancouver and BC planning figures reviewed July 27, 2026. Published prices are not quotes, and the widest ranges usually combine fundamentally different scopes. Ask contractors to separate diagnosis, demolition, drainage, waterproofing, electrical work, permits, and restoration.

Basement Waterproofing Cost Calculator
Choose a repair scope and enter a measurable quantity. The calculator applies the published local ranges cited on this page and shows a broad budget band—not a contractor quote.
Estimated planning range
$5,600–$18,400
CAD before tax
$70–$230 per linear foot, checked against published local whole-project ranges.
This estimate intentionally stays broad. It does not price permits, engineering, hazardous-material work, mould remediation, shoring, landscaping, finished-room restoration, tax, or hidden conditions. A safe repair method cannot be selected from price alone.
| Repair scope | 2026 planning range | Why the range is wide |
|---|---|---|
| Foundation crack injection | $300–$2,500 per crack | Published Vancouver and BC ranges overlap at the low end but widen when exterior access, finish removal, movement, or a structural repair is involved. |
| Sump pump | $500–$2,500 typical; complex new systems can exceed $4,500 | A pump replacement in an existing pit is not comparable to cutting a new pit, adding discharge, electrical work, an alarm, and backup power. |
| Interior drainage system | $3,000–$18,000+ | Published ranges depend heavily on whether the quote covers a short problem area or a full perimeter with slab cutting, wall membrane, and a sump system. |
| Exterior waterproofing | $10,000–$30,000+ | Excavation depth and equipment access usually dominate the budget. Decks, concrete, utilities, landscaping, and difficult backfill can move a project above published ranges. |
| Drain tile replacement | $8,000–$30,000+ | Local published starting prices and full-replacement ranges vary with perimeter length, depth, pipe condition, access, and surface restoration. |
| Crawlspace encapsulation | $8,000–$25,000 for many Lower Mainland homes | This broad local planning range assumes more than loose poly. Drainage, standing water, mould, insulation, dehumidification, and low-clearance access can materially change it. |

Compare scope, not just totals
Questions that make quotes easier to compare
- What evidence supports the proposed cause?
- Which parts of the water path does this scope address?
- What preparation and restoration are excluded?
- What conditions could change the price after work begins?
- What exactly is covered by the workmanship or product warranty?
Budget examples
Three scopes that should not share a price
Localized leak through one stable poured-concrete crack
A contractor may recommend an interior polyurethane injection after confirming that the crack is not moving and water is not entering elsewhere.
Understand this repair scope →Water at the wall-floor joint around several walls
The quote may include slab cutting, an interior perimeter channel, wall drainage material, a sump pit, discharge, and finish removal.
Understand this repair scope →Failed exterior membrane or perimeter drain
Excavation, utility locating, membrane, protection board, drain tile, drainage rock, backfill, and surface restoration can make this a major project.
