Window Installation in Canmore and Banff
If you need window installation in Canmore, you need windows that handle freeze-thaw cycles, intense UV at 1,300 metres elevation, snow loads, and Chinook wind shifts of 30 degrees in an hour. Windows Canmore has installed more than 1,200 windows across Canmore, Banff, Harvie Heights, Dead Man's Flats, Exshaw, and Kananaskis since 2014. Every window we install is Energy Star certified for climate zone 3, NAFS-11 tested, and backed by a 25 year glass warranty plus our 10 year installation guarantee.
From full home replacements to custom alpine-shape windows, every service below is delivered by our in-house Bow Valley crew. We do not sub out installs or pass calls to Calgary.
Full home replacements with triple-pane, low-E argon, Energy Star certified units sized for Canmore climate zone 3.

Learn more →"Our 1990s cottage in Canmore was bleeding heat through old aluminum frames. The crew swapped 14 windows in 3 days, sealed everything in driving snow, and the south side of the house has not condensed once this winter. Heating bills are down close to 30 percent."
"They handled every step of the Greener Homes Grant for us. Pre audit, install, post audit, rebate paperwork. We received $3,400 back and the new triple-pane casements completely changed how the living room feels in February."
"Quoted by two Calgary companies that wanted us to drive in for a showroom visit. Windows Canmore came to the property, measured, quoted on the spot, and beat both prices. The install crew was professional and tidy. Highly recommend."
Every window we install is Energy Star certified for climate zone 3 (the coldest in southern Alberta), NAFS-11 tested to PG50 wind and water performance, and configured with low-E argon triple glazing as a default. We spec frames that handle 1,300 metre UV intensity without chalking and seal systems rated for repeated freeze-thaw cycles.
Stat: 95 percent of our installs use triple-pane glazing.
Bow Valley owned and operated since 2014. Our installers live here. We do not charge "mountain travel fees" or hand your project to a Calgary sub-contractor. Free in-home measurement means you skip the 90 minute drive to a city showroom and we quote on materials we can actually deliver to your front door in 6 to 10 weeks.
Stat: 1,200+ windows installed across the Bow Valley.
The Canada Greener Homes Grant returns up to $5,000 for qualifying retrofits, but the audits, documentation, and rebate application are a chore. We coordinate the pre and post energy audits, format invoices to Natural Resources Canada specs, and submit the application with you. Most of our clients capture rebates without ever opening the federal portal.
Stat: Average rebate captured per home: $3,200.
We come to you. No showroom drive to Calgary. No high-pressure pitch. Just an honest quote on the right windows for your home.
We install every major operating style. Bow Valley orientation, wind exposure, and view direction usually dictate which one is right for each opening. Here is how the six common styles perform in our climate.
Crank-operated, hinged at the side, the sash compresses into the frame when locked which produces the tightest air seal of any operable style. According to NFRC data, casements achieve up to 15 percent lower air leakage than sliders under high wind exposure. That matters on west-facing Canmore homes that see 80 km/h Chinook gusts each spring. We default to casements for any opening that does not require accessibility-friendly operation.
Stat: Up to 15% tighter seal than sliders under wind load (NFRC).
Hinged at the top, awning sashes open outward and downward. The sloped open position lets you keep them open during rain or light snow without water reaching the sill. They are common above kitchen sinks and combined with large picture windows where you want passive ventilation without giving up view glass. Awnings carry similar seal performance to casements thanks to the same compression locking system.
Stat: Energy Star Most Efficient list includes more awning units than any other operable style.
Horizontal sliders are the most common style in older Canmore subdivisions because they suit wide rough openings without the clearance casements need. Modern Canadian-made sliders have improved dramatically: triple-pane glazing, warm-edge spacers, and reinforced meeting rails close most of the seal-performance gap with casements. Sliders are also frequently the answer for egress-required basement bedrooms.
Stat: Egress requirement in Alberta basements is 0.35 m² of openable area, minimum.
Two vertically sliding sashes, both of which open. They suit heritage exteriors common in central Banff and the older Canmore townsite where the architectural review board favours traditional profiles. Both sashes tilt inward for easy cleaning, useful on second-storey installations. Modern double-hung units carry double-weatherstripped meeting rails to handle Bow Valley driving snow.
Stat: Banff design guidelines explicitly reference traditional sash window proportions for buildings in the heritage district.
Multi-pane projections that push past the wall plane to frame mountain views like the Three Sisters or Cascade Mountain. Bay windows use three panes at angled corners, bow windows use four to six gentler curves. Both require structural cabling or knee bracing for spans above 1.5 metres. We design seat boxes with insulated bases rated for our climate so the projection does not become a cold spot.
Stat: Projected windows add usable interior square footage without expanding the foundation footprint.
A non-operating window with the entire sash dedicated to glass. Because there is no hardware and no opening seam, picture windows produce the lowest U-factor and highest passive solar gain of any window style. They are the right choice anywhere a view is the priority and ventilation is handled by adjacent operable units. We routinely install fixed lites above 2.4 metres tall with structural reinforcement.
Stat: Picture windows can achieve U-factors below 0.20, the strictest Energy Star Most Efficient threshold.
Frame material and glazing dictate window lifespan in our climate more than any other factor. Here are the four pieces of every quote we prepare.
Multi-chamber PVC with welded corners. Maintenance-free, won't rot or warp, and Canadian-made vinyl is engineered for cold climate impact resistance down to minus 40. Premium grades resist chalking under high UV at altitude.
Stat: Vinyl windows make up 65% of Canadian window sales (Fenestration Canada).
Pultruded fiberglass expands at the same rate as glass which reduces seal stress in temperature swings. The strongest option for tall picture windows. Can be painted dark colours without thermal warping, suitable for mountain-modern dark exteriors.
Stat: Fiberglass frames typically last 50+ years before replacement.
Three panes of glass with two gas-filled gaps. Cuts heat loss roughly 30 percent vs double-pane and eliminates interior edge condensation in minus 25 temperatures common across Canmore in January. Standard on every quote we prepare.
Stat: Triple-pane cuts U-factor from ~0.30 to ~0.17 in zone 3 specifications.
Microscopic metallic coatings reflect interior heat back inside during winter and block UV that fades hardwood floors and furniture. Argon gas between panes insulates roughly 35 percent better than air. Krypton is available for tight-spaced triple-pane units.
Stat: Low-E coatings block up to 84% of UV transmission (NRCan).

No franchises. No sub-contractors. No Calgary callbacks.
Read Our Story
Based in the heart of Canmore. Our crew works daily across the Bow Valley and along Highway 1 from Lake Louise to the edge of the foothills. We know the permit requirements, the design review constraints, and the practical realities of installing windows in a national park town and on cabin properties off Smith-Dorrien Road.
