Window installation
and replacement in Calgary

CPR Group Ltd installs and replaces residential and commercial windows across Calgary, improving energy efficiency, comfort, and curb appeal while maintaining a weather-tight envelope. Windows are one of the biggest thermal weak points in any Calgary home, and replacing aging single-pane or poorly sealed units with modern double- or triple-pane systems delivers a measurable difference in heating costs and comfort.

Since 2007, CPR Group has handled window replacement projects from single-unit failures to full-house upgrades on residential and commercial properties.

Since 2007

18+ Years of Window Replacement
in Calgary

CPR Group Ltd has replaced windows across Calgary since 2007, on heritage renovations, hail damage claims, and full exterior renovation projects. The window itself is only half the job. The other half is the rough opening: the flashing, insulation, air barrier, and trim details that actually keep water out and heat in.

CPR Group's formal building science training means the crew treats the rough opening as carefully as the window unit, and our HAAG Certified Inspectors verify the details before the job closes.

Every CPR Group window replacement project is backed by $5 million in commercial general liability coverage through Federated Insurance, SECOR safety certification, active WCB-Alberta coverage since February 2013, membership in the Alberta Allied Roofing Association (AARA) since 2021, and a BBB A+ accreditation held continuously since July 2015.

Know the Signs

When to Replace Windows in Calgary

01

Visible condensation or frost inside the glass.

Condensation or frost between the panes means the seal has failed and the insulating gas has leaked out. The window is no longer performing and can't be repaired.

02

Drafts you can feel at the frame.

If you can feel cold air at the window frame in winter, the air sealing at the rough opening has failed, or the window gaskets have hardened. Both are common on Calgary windows over 20 years old.

03

Heating bills that climb year over year.

Rising heating costs without a rate or usage change often point to window and door seals degrading. Replacement typically pays back through lower bills and better comfort.

04

After hail or wind damage.

Calgary hail events can crack glass, dent frames, and damage window screens. Insurance claims often cover the replacement, and upgrading to impact-rated glass can reduce future risk.
