Building Envelope Repair Cost Guides

The main cost drivers on a Metro Vancouver building envelope repair project: access method (rope access is the most cost-effective for distributed work; swing stage and scaffolding add mobilization cost for heavier scopes); scope size (linear metres of sealant, square metres of membrane or coating, number of spall repairs); building height and geometry (complex facades, multiple setbacks, and tight urban sites add access time); substrate condition (active water damage, rotten framing, or corroded rebar found under the original scope add remediation cost); and material specification (elastomeric vs. acrylic coating, silicone vs. polyurethane sealant, membrane system type all carry different material costs).

From our 2026 pricing: a balcony overlay (applying new membrane over a sound existing membrane) runs $15–$35 per square foot installed, depending on system and deck condition. A full tear-off and replacement — stripping the existing membrane to the slab, repairing any concrete edge damage found, and installing a new system — runs $35–$75+ per square foot. Deck size, access complexity, and the extent of concrete edge repairs found during tear-off are the main variables. A per-deck assessment is the only way to scope the actual cost for a specific building.

From our 2026 pricing: a single floor of window perimeter sealant replacement runs $3,000–$8,000 depending on lineal metres of joints on that floor. A full 10–20 storey building sealant program runs $25,000–$80,000+ for the complete window perimeter scope. These figures include rope access mobilization, full strip-out of the old sealant, backer rod, commercial-grade polyurethane or silicone product, and tooling. The full cost guide in this section provides detailed ranges by scope type.

Concrete spall repair cost depends almost entirely on how many repairs are needed and the depth and area of each individual spall. From our 2026 pricing: small spall repairs (under 0.25 m²) run $200–$600 per repair depending on depth and reinforcing steel condition. Medium repairs (0.25–1 m²) run $600–$2,500. Large section or full-depth repairs run $2,500–$8,000+ per location. Rebar treatment (rust removal, inhibitor application, or tie-in of supplemental steel) adds cost. The full cost guide has more detail on repair classification.

Range estimates based on building type, approximate scope, and service type are possible without a site visit — and we provide them on request for strata budgeting purposes. However, a budgetary range is not a contract price: actual scope depends on what's found on-site (the extent of failed sealant, the number and depth of spall repairs, the condition of existing membranes, what's under the surface). The cost guide in this section provides the ranges we use for strata budget planning — final pricing follows a site assessment and written scope.

A depreciation report provides funded cost estimates for scheduled replacement of building envelope components — it's a planning and reserve fund document, not a construction estimate. The costs in depreciation reports are often based on industry average per-unit pricing that may not reflect current Vancouver contractor rates, current material costs, or the specific condition of the components on your building. When a depreciation report flags a component for replacement, a condition assessment and contractor scope are the next steps before the strata budgets the actual reserve draw.
