Building Envelope Specialists · Toronto & the GTA
Who we build for
Since 2012 we've moved beyond residential siding into complete, high-performance wall assemblies — the membranes, sub-framing, insulation and cladding that keep water out, energy in, and facades looking sharp. We work as a partner: no surprises, tight coordination, and finishes that meet the drawings.
Start a project →Reliable envelope scope, schedule discipline and clean hand-offs on ICI and multi-family builds.
Energy-code-compliant assemblies that protect long-term asset value and reduce operating cost.
Re-clad, retrofit and repair programs that modernize the facade and extend service life.
What we install
Four core systems, engineered together. Each links to full specifications, materials and detailing.
Thermally broken Z-girt and clip systems with continuous insulation and a drained, ventilated cavity.
Explore system → 02Aluminum composite, insulated metal panels, aluminum plate and metal siding — fabricated and installed.
Explore system → 03High-density cement panel and fiber cement cladding for clean architectural lines that last.
Explore system → 04Weather-resistive barriers, membranes, precision flashing and sealant — the waterproofing backbone.
Explore system →Signature system
Continuous metal girts transfer heat straight through the assembly. We break that bridge — with fiberglass girts, thermal clips and offset attachments — so the wall hits its effective R-value, controls condensation, and meets today's energy codes.

Isolates cladding from structure to stop heat flow and cold-spot condensation.
18-ga girts carry the cladding while semi-rigid or rigid insulation fills the cavity.
A drained, back-ventilated air gap keeps the finish dry and long-lived.
How we work
A predictable process built for ICI schedules and inspections.
We review architectural details and specs, flag envelope risks early, and price a scope with no surprises.
Barrier, sub-framing, insulation and cladding are detailed to hit thermal, moisture and fire performance.
Trained crews install in sequence, keep the site clean, and coordinate tightly with other trades.
Detailing verified against the drawings, documented, and handed over ready for occupancy.
Selected work
A cross-section of cladding and envelope projects across the Greater Toronto Area.
Why Toronto Siding Pro
We combine a decade of exterior craftsmanship with genuine building-science detailing — and we stand behind the work. The result is envelopes built for the Ontario climate: freeze-thaw, driving rain and real energy performance.
Working with materials from Rockwool, Henry, Soprema, IKO, Owens Corning, Cascadia, ISO Clip & more.
