Building Exteriors

Cladding, facades, glazing, roofing, and envelope upgrades, engineered for Vancouver Island's coastal climate and delivered on occupied buildings with minimal disruption to tenants.

[Start a conversation]
Exteriors are usually treated as a finish trade. That is how envelopes fail. The cladding goes up before the moisture detailing is right. Flashings sit in the wrong plane. Sealants are asked to do work that geometry should have done. Five years later the leaks show up, and by year ten the building has lost ten percent of its value. EDDA approaches the envelope as the building science discipline it actually is. Cladding aesthetics matter. Detailing matters more. Greater Victoria's marine climate is gentler than the rest of British Columbia in many ways and tougher in others. Long wet shoulder seasons. Salt-laden air on waterfront sites. Building science strategies that work in interior BC do not all transfer. EDDA's detailing reflects what works locally.

Scopes

Scopes we deliver

  • Cladding replacement (rainscreen, panel, fiber cement, metal, wood, masonry).
  • Window and curtain wall replacement.
  • Roofing replacement and waterproofing.
  • Air barrier and moisture management upgrades.
  • Sealant and joint remediation.
  • Heritage and facade restoration in character buildings.
Most envelope work happens on buildings that remain in use during construction. Scaffold and swing-stage access, falling-debris protocols, tenant communications, and weather contingency plans are all part of EDDA's standard scope. The building stays open. The work gets done.

What is a building envelope?

A building envelope is the system of walls, windows, roof, and detailing that separates the interior of a building from the exterior. It controls air, water, vapor, heat, and sound transfer.

When should a building envelope be replaced?

Envelope replacement is typically warranted when there are persistent leaks, visible cladding failure, energy performance issues, or end-of-life roofing. A condition assessment is the right first step.

How much does envelope work cost in Greater Victoria?

Costs vary widely by scope, cladding system, building height, and access conditions. A condition assessment and preliminary scope from EDDA produces a realistic budget range before commitments are made.

Can EDDA work on heritage and character buildings?

Yes. EDDA works on heritage and character buildings in Greater Victoria, with detailing and material choices that satisfy heritage requirements while meeting modern performance standards.

What is rainscreen cladding?

Rainscreen cladding is a cladding system that separates the exterior cladding from the air and moisture barrier behind it, allowing drainage and ventilation. It is the standard for new construction and most envelope retrofits on Vancouver Island.
