Windows and doors that keep Alberta weather outside
Drafty windows and worn doors don't just look tired — in a Calgary winter, they cost you comfort and heating money every single day. Shield Exteriors replaces windows and entry doors across Calgary, Airdrie, Cochrane, and Okotoks with energy-efficient units built for our climate, installed and sealed by crews who work Alberta exteriors year-round.
WHAT WE DO
Our Window and Door services
Window replacement
Whether your siding is faded, cracked, or you're simply ready for a new look, a full replacement transforms your home's curb appeal and protection in one project. We remove the old siding, inspect and repair the sheathing and building wrap underneath, and install your new siding with matching trim and finishing details — so the whole exterior reads as one intentional design.
Skylight installation & replacement
A skylight is a window for the one wall the sun hits all day — your roof. It brings natural light deep into kitchens, bathrooms, and hallways that regular windows can't reach, which matters through Calgary's long winters. We install new skylights and replace aging or leak-prone ones, with proper flashing and sealing so they stay watertight through every freeze-thaw cycle. Considering one during a roof or exterior project? That's the most cost-effective time to add it.

Entry & patio doors
A siding replacement is the one time the outside of your walls is open — the perfect moment to add continuous exterior insulation. It wraps your home in an unbroken thermal layer, cutting drafts and energy bills and keeping the house more comfortable in Calgary's deep freezes and summer heat. Ask about it with your estimate; the add-on cost is far lower during a replacement than as a standalone project.
Storm & hail damage
Hail tears screens, cracks vinyl frames, and can break sealed units — damage that's commonly covered under the same claim as your roof and siding. Our free assessment documents it all, and we handle the claim with you and your insurance company. Learn how the process works on our insurance claims page.
MATERIALS
Glass and frames for a Calgary climate
Double pane or triple pane
Double-pane with Low-E coatings and argon fill is the modern baseline and a huge upgrade over older windows. Triple-pane adds another layer of glass and insulation — noticeably warmer interior glass on -30° mornings, better street-noise dampening, and less condensation risk — for a higher price. We'll show you both and price both, so the choice is yours with real numbers.
Vinyl frames, finished right
Low-maintenance vinyl frames in colour options to suit your exterior, with the exterior finishing around each opening included in the install — no half-done edges, no "someone else will trim that." And if a project ever does call for custom metal work around an opening, we can take care of that too.
Every replacement includes colour and style selection
