The Ranking

Our top 10 window companies in Calgary

Calgary asks a lot of a window. Winter nights drop well below freezing, chinooks swing the temperature by 20 degrees in a day, hail can crack glass in minutes, and heating a house here costs real money. Much of the older housing stock is 1950s to 1970s bungalows and infill in the inner southwest, southeast and northeast, where original aluminum or early vinyl windows leak air and fog between panes, while newer suburbs in the northwest and south have builder-grade windows that are reaching replacement age. Basements are the other common job, because bedroom egress windows and window wells are a code issue as much as a comfort one.\n\nWhen you compare quotes, look at the ratings printed on the window. ENERGY STAR certification and the NFRC label tell you how a window performs on heat loss and solar gain, and triple glazing with Low-E coatings and an insulating spacer is the usual choice for Calgary winters. Ask each company whether the quote covers removal, disposal, interior trim, caulking and any structural repair. Replacing a window in the same opening usually does not need a City of Calgary permit, but cutting a larger opening or adding a basement egress window can, so confirm with the City or ask the installer to explain who handles it.\n\nIf your house was built before the late 1970s, the old frames may carry lead paint. Health Canada says homes built before 1960 are the most likely to contain it, and some paint made into the 1980s can too. Ask how the crew controls dust when removing painted trim, and in the United States the equivalent rule is EPA RRP certification, which does not apply here but shows what careful practice looks like.\n\nAlberta does not issue a provincial licence for window and door installers, so the checks are yours to run. Ask for a current WCB clearance letter, a certificate of liability insurance, the City of Calgary business licence, a written quote with a start date and the full warranty text. None of the ten companies here publishes a contractor licence number, and each profile says what the company states about itself and what we could not confirm. Several make their own windows, while others sell through a showroom and install with their own crews, so ask who will actually be on your roof or ladder.

Methodology

How we chose the best window companies in Calgary

We searched Google Maps for window replacement, windows and doors companies, and entry door and patio door installation in Calgary on November 3, 2026, and listed the companies that passed in Google's own result order. Each had to be operating, rated 4.5 or higher from at least 50 Google reviews, have a working own website, a real logo, photos and a staffed street address in Calgary. We excluded glass repair shops, commercial storefront glaziers, handyman franchises, home addresses, keyword-stuffed listings, companies with too few reviews and second listings of the same brand. Several larger Calgary brands were not included because their websites could not be read in full during our check. Licences, warranties and installation claims are the companies' own statements unless noted. No company paid for a place. Ratings and review counts were read on November 3, 2026.

Hiring

How to choose a window company in Calgary

  1. Verify insurance and credentials

    Ask for a current certificate of insurance and confirm registration or licensing with the authority that issues it, not with the company.

  2. Ask for a written estimate

    Scope, materials, removal, disposal and who pulls the permit should all be named on the page rather than agreed on the doorstep.

  3. Compare multiple quotes

    Two or three bids on the same scope. A number far below the others usually means something has been left out of it.

  4. Understand the warranty

    Separate the manufacturer's warranty on materials from the company's own warranty on the work, and get both in writing.

  5. Ask who performs the work

    Find out whether the crew are employees or subcontractors, and who supervises them on the day.

  6. Check recent local projects

    Ask for addresses or photographs of comparable jobs finished nearby in the last year or two.

  7. Avoid high-pressure sales

    A discount that expires today, or a knock on the door after a storm, is a reason to slow down rather than sign.

  8. Get everything in writing

    Change orders, timeline and payment schedule included, before the first payment changes hands.

Questions to ask before hiring

0 of 10 asked

Red flags

  • No verifiable local business address or registration
  • Pressure to sign on the first visit
  • A demand for full payment up front
  • An offer to cover or waive your insurance deductible
  • Refusal to put warranty terms in writing
  • A quote that will not itemize scope

FAQ

Windows and doors companies in Calgary FAQs

Does Alberta or Calgary require a licence for window and door installers?

Not at the provincial level. Alberta has no general contractor licence for window and door work, so the checks are yours to run. Ask for a current WCB clearance letter, a certificate of liability insurance, the City of Calgary business licence and a written quote. None of the ten companies here publishes a licence number, and each profile says so.

Do I need a permit to replace windows in Calgary?

Replacing a window in the same opening usually does not need a City of Calgary permit, but enlarging an opening or adding a basement egress window can. Confirm with the City before work starts, and ask your installer in writing who is responsible for any permit and inspection.

Which Calgary window companies are open on Saturday?

Six of the ten: Norden Seal, GreenFox, Window Seal West, Window Mart Calgary, All Star Home Windows and Doors, and Permanent Windows Solutions. Best Solution, Royal View, Canadian Choice and Western Windows are closed on weekends, so check hours before visiting a showroom.
