Why homeowners choose Weather Pro
Most window companies in Canada sell products built by someone else. Weather Pro is both the manufacturer and the installer, so one company is accountable for the product, the installation and the warranty.
A Canadian manufacturer, not a reseller
We manufacture our vinyl windows in Canada and sell them factory direct. There is no distributor and no middleman between our factory and your home.
Our own installation crews
Your windows are installed by Weather Pro crews, not by subcontracted trades. The company that builds the product is responsible for how it goes in.
ENERGY STAR certified windows
Our windows meet ENERGY STAR requirements for the Canadian climate zones in which they are sold.
Transferable lifetime warranty
Coverage stays with the home. If you sell, the warranty transfers to the next owner.
Price Match Policy
We offer highly competitive rates and will match any verified competitor price for the exact same product under our Price Match Policy.
Single-day installation on most homes
Most replacement projects are completed in one day, so your home is closed up the same evening.

Our Simple 6-Step Process
Measurement
At the first stage, our specialist carefully takes measurements of windows and doors. Using professional measuring tools, we guarantee the accuracy of each measurement to ensure a perfect fit for your needs.
Product Demonstration
At the second step, we present the selected product to you. It is important for you to personally see the quality and design of the item, and to ensure that it will perfectly complement the interior of your home.
Estimate Preparation
In the final step, we provide a precise and transparent estimate. We detail the costs and outline the services to ensure you have a clear understanding of the investment. Our aim is to give you all the information needed to make a confident decision regarding your home’s improvement.
Order & Factory Build
After you approve the estimate, we place your order and build your windows and doors to the measured sizes. As a Canadian manufacturer, we produce the units for your project rather than pulling generic stock, so each opening gets a purpose-built fit.
Professional Installation
On install day, our trained crew protects your floors, removes the old units, and prepares each opening. Your new windows or doors are set level, sealed against air and moisture, and insulated before finishing, then debris is removed so you are not left with cleanup.
Walkthrough & Warranty
When the work is complete, we walk you through how your new windows and doors operate and what your warranty covers. You leave with a clean home, clear next steps for care, and confidence that the project is finished properly.

Vinyl replacement windows in 12 styles
We manufacture 12 vinyl window styles, so a whole-home replacement can combine operating and fixed units without ordering from multiple suppliers. Every style uses the same frame system, glass packages and colour range, which keeps the exterior consistent across the house.
Casement windows
Crank open on a side hinge and seal tightly against wind, which suits most exposed elevations.
Awning windows
Hinge at the top and can stay open in light rain, common above kitchen counters and in basements.
Exterior and entry doors built for Canadian winters
Weather Pro also manufactures and installs exterior and entry doors. Our door systems use insulated cores, multi-point hardware, and weather sealing, built to withstand freeze-and-thaw cycles. Replacing a front door is often the quickest way to eliminate a persistent draft at a home’s entry, and a door can be installed on the same visit as a window project.
Fibreglass and steel entry doors, glass inserts and sidelites, and matching frames are available in the same colour range as our windows.

Energy-efficient windows built for the Canadian climate
Energy performance in a Canadian home is determined by the glass package, spacer, and seal, not by the frame alone. Our windows are engineered around those three components.
Double pane and triple pane glass
Double-pane windows with a low-E coating and argon fill are our standard package. Triple-pane windows add a third layer of glass and a second sealed cavity, which further reduce heat loss and outside noise. In the Prairie provinces, where winter design temperatures are among the lowest in the country, triple-pane is the package most homeowners choose for north- and west-facing elevations.
Warm edge spacers and the Quad Seal System
We build with SuperSpacer Premium Plus warm-edge spacer technology, which reduces heat transfer at the edge of the glass unit, where condensation typically starts. Our Quad Seal System adds four sealing points between sash and frame to limit air leakage.
What ENERGY STAR certification means
ENERGY STAR for windows in Canada is administered by Natural Resources Canada. A window bearing the mark meets a defined performance level for the climate zone in which it is sold, making it a verifiable standard rather than a marketing claim. Every Weather Pro window is ENERGY STAR certified.
The Quad Seal System: Four Layers of Protection in Every Window
Most vinyl windows rely on a single or double seal. Every window Weather Pro manufactures is built with the Quad Seal System, four sealing layers that work together to keep air, moisture, and cold out of your home.
How the four layers work
- 1Exterior frame seal. The outermost layer meets wind-driven rain and snow first and stops water before it reaches the opening.
- 2Vapour barrier. The second layer blocks moisture from moving through the frame, which is where condensation and frost usually begin in a cold climate.
- 3Insulated glass cavity. The sealed cavity between the panes holds the insulating gas fill in place and keeps the glass package performing over time.
- 4Interior seal. The final layer closes the last air path between the sash and the frame, so warm indoor air stays inside.
What this means for your home
- Fewer drafts, because each layer closes off another path for cold air.
- Lower heating costs through a long Alberta winter.
- Less condensation and frost along the glass.
- Protection that holds as frames expand and contract through freeze-and-thaw cycles.
Because we manufacture our own vinyl windows, we build the Quad Seal System into every unit at the factory rather than adding it during installation. Book a free in-home estimate and see the sealing system for yourself.
How much does window replacement cost
Window replacement costs in Canada depend on four factors: the number of openings, the window style, the glass package, and whether the opening needs framing work. Retrofit installations, where the existing frame stays in place, cost less than full-frame replacements, where the frame is removed back to the rough opening.
Because we manufacture what we install, our pricing is factory direct rather than dealer pricing. Every project is quoted in writing after an in-home measurement, so the figure you receive is the figure you pay.

Looking for a window company near you
Weather Pro runs its own branches and installation crews. When you book, the crew that arrives works for Weather Pro out of the nearest location, not a subcontractor dispatched from another city. That is the practical difference behind most searches for a window company near me: whether the people at your house work for the company that built the windows.
Our two Alberta branches handle the largest share of our replacement work.
Free in-home estimates are available within 50 km of Calgary and Edmonton. Outside that radius, we still quote. Call the closest branch, and we will confirm the lead time for your address before you book anything.
We also install across Saskatchewan, Manitoba, Ontario, Nova Scotia, New Brunswick and British Columbia.
Transferable lifetime warranty and Price Match Policy
Our warranty covers manufacturing defects for the life of the product and transfers to the next owner if you sell the home, which protects the value and comfort of the upgrade. Because we manufacture and install, a warranty claim goes to one company rather than being passed between a supplier and a contractor.
We offer highly competitive rates and will match any verified competitor price for the exact same product under our Price Match Policy. A written competitor quote for the identical product is required, and each match is approved by a regional manager.
What backs a Weather Pro window
Our windows are certified to Canadian standards and carry a transferable lifetime warranty. We manufacture in Canada and install with our own crews. The glass and door components come from established North American manufacturers; we are members of both national industry associations.
