WHERE THE FIRST THING WE BUILD IS TRUST

Building envelope restoration services in Calgary

CPR Group Ltd restores failing building envelopes on residential and commercial properties across Calgary, fixing the exterior wall, roof, insulation, and air barrier assemblies that protect the building from moisture, air leakage, and thermal loss. Since 2007, CPR Group has used building science principles to diagnose envelope failures at the source, not just the visible damage, so repairs actually solve the underlying problem.

If your building has persistent leaks, condensation, ice dams, or rising energy costs, the envelope is usually where the problem lives.

Building envelope repair:

CPR Group repairs failed wall assemblies, damaged roofing systems, and compromised insulation that have allowed moisture, air, or thermal bridging into the structure.

Moisture and leak investigation:

Our crew traces envelope leaks to their actual source, not just where water shows up inside, using building science principles, thermal imaging, and HAAG-certified inspection methodology.

Waterproofing and air sealing:

CPR Group installs membrane waterproofing, air barriers, and sealed penetrations to stop water and air infiltration at the wall and roof assemblies, protecting the insulation and framing behind.

Thermal insulation and thermal bridging repair:

Our team addresses cold spots, condensation zones, and insulation voids that show up on thermal imaging, improving energy performance and eliminating the conditions that grow mould.

Facade restoration:

CPR Group restores damaged exterior cladding, siding, trim, and flashings that form the first line of defence against Alberta's weather.

Roof and roof-to-wall detailing:

Our HAAG Certified Inspectors check the roof assembly and the critical roof-to-wall junctions where envelope failures most commonly start, then rebuild the details correctly.

Since 2007

18+ Years of Building Envelope
Restoration in Calgary

CPR Group Ltd, a Calgary restoration contractor since 2007, has restored building envelopes across Calgary, combining hands-on roofing and exterior experience with formal building science training.

CPR Group understands how water, air, and heat actually move through Alberta wall and roof assemblies, and our HAAG Certified Inspectors produce the documentation needed to justify envelope repairs to property managers, insurance adjusters, and condo boards. Envelope work is rarely cosmetic. It's almost always about protecting the structural and mechanical investment behind the cladding.

Warning Signs

Signs Your Building Envelope Is Failing

01

Persistent interior leaks after storms.

Recurring stains on upper floor ceilings, around windows, or at roof-to-wall junctions are envelope failure symptoms. Surface patching rarely solves them because the leak source is usually several feet away from where water appears.

02

Condensation, frost, or mould inside walls.

When warm interior air reaches a cold surface inside the wall, it condenses, feeds mould, and degrades framing. This is an air barrier and insulation failure, not a plumbing or ventilation problem.

03

Ice dams every winter.

Chronic ice damming along the eaves means heat is escaping from the attic, melting roof snow, and refreezing at the cold overhang. That's an insulation, air sealing, and ventilation failure in the envelope.

04

Rising energy bills with no change in usage.

When a building's heating costs climb year over year without a rate change or usage change, the envelope is usually losing more heat than it used to. Thermal imaging can show exactly where.
