Waterproofing
Foundation to podium deck, plus crack injection — our signature fix for water finding a way through concrete nobody else can seal.
Air & Vapour Barrier
Continuous air and vapour barrier assemblies, installed to the drawings — not to guesswork — so the envelope actually performs.
Insulation
Exterior insulation tied cleanly into the air barrier and the cladding above it, built to the thermal spec on the drawings.
Siding & Cladding
The full envelope's outer face — metal panel, siding and cladding systems installed plumb, true and weather-tight, on schedule.
Roofing — Coping & Flashing
Metal coping, flashing and steel roofing — the details that take the weather first and can't afford to fail.
Railings, Ladders & Roof Access
Guardrails, access ladders and roof-access systems built to code, so your maintenance crews get up there and back down safe.
Not a sub working blind. A contractor who built the trade.
Your envelope is one system — waterproofing, barriers, insulation, cladding and roof all working together. That's the work we're built for.

Premium specialty
Corten & weathering steel. The architectural rustic look.
A rusted-steel face that reads a hundred years old and costs like it's new. We fabricate and install corten and weathering-steel panel systems for lobbies, feature walls and facades built to stand out, not blend in.
It's a premium finish, not a paint job — the surface weathers on purpose, and keeps protecting the structure behind it for decades.
