Weather Pro manufactures and installs energy-efficient vinyl windows and exterior doors for Calgary homes, sold factory direct and fitted by our own crews. Every project is backed by a transferable lifetime warranty and a free in-home consultation.
Weather Pro is a Canadian windows and doors manufacturer, and one of the more established names for window replacement in Calgary. Because we build and install our own products, you deal with one accountable team from the first measurement to the final install, rather than a chain of middlemen. This factory-direct model keeps our pricing competitive while still standing behind a transferable lifetime warranty.
We specialize in vinyl windows in Calgary. Vinyl is a durable, low-maintenance material that withstands Alberta’s freeze-thaw cycles without warping, rotting, or repainting, which is why it is the most popular choice for replacement windows in the city.
Our focus in Calgary is replacement work: swapping tired, drafty, or fogged units for modern triple-glazed windows and insulated exterior doors. Whether you are planning a full home upgrade or replacing a few failed units before winter, the process, the warranty, and the crews are the same. You can also explore our products in person at our Calgary showroom or through the online 360-degree virtual tour.
Calgary windows have to handle deep winter cold, strong prairie winds, and rapid Chinook temperature swings. Triple glazing, warm-edge spacers, and tight multi-point seals are what keep a Calgary home comfortable through all seasons.
- Triple pane windows in Calgary slow heat loss with insulating gas fills during a cold snap
- Insulated vinyl frames and multi-point locking keep air and moisture out during high winds
- Low emissivity coatings reflect heat back into the room in winter
- Warm edge spacers reduce condensation when temperatures swing
- Better draft protection. Four sealing points block air movement far more effectively than a single seal.
- Improved energy efficiency. A tighter seal keeps conditioned air inside, so your heating and cooling work less.
- Lasting performance. Layered seals stay effective through Calgary’s temperature swings.
Long-Lasting Durability at an Affordable Price
Window types we install in Calgary
We install the full range of vinyl window styles. The right choice depends on the room, the look you want, and how much ventilation and access for cleaning matter to you.
Awning windows
Hinged at the top and opening outward from the bottom, awning windows let air in while keeping rain and snow out. That top hinge is the key difference from a casement, making it a reliable choice for ventilation during Calgary’s wetter months. They are often placed higher on a wall or above other windows.
Tilt and turn windows
Built to a European standard, tilt-and-turn windows open two ways from a single handle: tilting in from the top for gentle airflow, or swinging in fully for maximum ventilation and easy cleaning. That dual action is what sets them apart, and the tight multi-point seal handles Calgary’s varying conditions well.
Specialty shape windows
Custom shapes such as arches, circles, and angled units are made to fit non-standard openings. They differ from stock rectangular windows in that they are built to the exact dimensions of the opening. Ideal for accenting entryways, stairwells, and feature walls.
Single slider windows
A single slider window glides horizontally along a track, with one sash that moves and one that stays fixed. The difference from a double slider is that only half the window opens, which keeps it simple and easy to operate. A dependable, low-maintenance choice for everyday openings in Calgary homes.
Picture windows
A fixed pane that does not open, a picture window is built purely to bring in light and views. Because there is no moving sash, it seals extremely well and loses less heat than an operable window, which suits Calgary’s cold winters. Best for feature walls and rooms where ventilation comes from nearby operable units.
Fixed casement windows
A fixed casement gives you the slim casement look without an opening sash. It seals as well as a picture window while matching the sightlines of operable casements beside it. Best used alongside operable casements for a consistent appearance.
End vent slider windows
An end vent slider combines a large fixed centre pane with two operable end sections, giving you a wide view and ventilation on both sides. It differs from a standard slider by keeping the centre view uninterrupted. Well suited to wide living room or kitchen openings.
Double slider windows
A double-slider window also glides horizontally, but both sashes move, so you can open either side or both to let in airflow from two directions. That extra flexibility is what sets it apart from a single slider, and both sashes tilt or lift out for easy cleaning. A practical fit for wider openings where a crank window would be awkward.
Casement windows
Hinged on the side and opened with a crank, casement windows swing outward for a full opening. Unlike sliding styles, they seal tightly against the frame when closed, making them among the strongest performers against Calgary’s winter drafts. Best where you want maximum airflow and a clear view.
Bay windows
A bay window projects outward from the wall in three sections, adding floor space, light, and a defined nook inside. It differs from a flat window by creating dimension and a shelf or seat. A strong feature for living rooms and dining areas.
Bow windows
A bow window curves outward across four or more sections for a softer, rounded projection. Compared with a bay, it spreads the projection more gently and suits wider walls. Adds architectural character and panoramic light.
Single hung and double hung windows
Hung windows open vertically, with a single-hung moving only the bottom sash and a double-hung tilting both for easy cleaning from inside. The difference from sliders is the vertical operation, which many homeowners prefer for a traditional look. A practical fit for bedrooms and living spaces.
Even a well-built window or door underperforms if it is fitted poorly. Weather Pro installs with its own trained crews, sealing and insulating each opening in accordance with Alberta building practices so every unit performs as it was designed to.
Installation is where a replacement project succeeds or fails. A quality triple-glazed window or an insulated entry door still leaks heat if the opening around it is not properly sealed and insulated, which is why we use our own crews rather than subcontractors. Each opening is squared, sealed, and insulated so there are no gaps for air or water to work through.
How does professional installation work in practice
On install day, the crew protects your floors and work area, removes the old windows or doors, and prepares the opening. The new unit is set level, secured, sealed against air and moisture, and insulated around the frame before the interior and exterior finishing is completed. The old units and debris are removed, and the area is cleaned before the crew leaves, so you are not left with cleanup or disposal.

Window replacement cost in Calgary depends mostly on how many windows you replace, the styles you choose, and the glass options. The ranges below are typical Alberta project estimates to help you plan; your exact price is determined by a free in-home quote.
The single biggest factor in a project’s cost is the number of windows, followed by the styles and glass upgrades, such as triple-pane and low-emissivity coatings. The table below gives typical Alberta ranges by home size as a planning guide, not a quote.
| Home size | Number of windows | Typical project range |
|---|---|---|
| Small 2 bedroom home | 15 to 20 | $12,000 to $18,000 |
| Medium 3 bedroom home | 20 to 25 | $15,000 to $22,000 |

| Larger or luxury home | 40 plus | $35,000 to $50,000 |

I loved the service. Each step was easy. I’m in love with the new windows, really changed the look of the house.
Weather Pro turned out to be a very good option. Cost effective, good customer service and their installation crew were on time, they cleaned up the site and the final work looked great! Thx
Our new windows arrived today, 3 weeks earlier than expected, and they are awesome! The sliders are so easy to open and they can opened in a way that makes them easy to clean from inside the house. The installers were very polite and efficient in the installation. They even tacked our trim up to finish the job. Cleaned up the work area, both inside & out. Super happy with this purchase. Highly recommended!!
Alek N and his crew were absolutely amazing worked like troopers. Attention to detail and CLEANING was a top priority for them stunning work and diligent to detail. Would highly recommend there window service and product anytime.
I want to express my sincere appreciation for the care and attention we received from the staff and crews at Weather Pro Windows and Doors. Alex Mirkin, Regional Manager, guided us through each step of the process, from choosing the right windows to explaining the installation and providing timely follow-up before, during, and after the work was completed. We are extremely pleased with the results and would not hesitate to recommend Weather Pro Windows and Doors. A special thank you to Bogdan, Supervisor of the international team, who was on site throughout the project. His craftsmanship and commitment to customer satisfaction were exceptional.
I had single pane before and weatherpro helped me upgrade to double pane. It’s unbelievable how much quieter my place has become. I really wish i would have upgraded earlier. I’m grateful to their salesperson who wasn’t pushy and explained everything clearly to me. The windows were 10 years old and my main goal was to reduce the noise, and I could hear it right away. The installation was fairly quick as the project wasn’t too big. Installers spoke English and cleaned after themselves. I’m happy with the results overall
I am so pleased with the team, the work they did, the details that I thought were left undone on the first day were well looked into and polished to my best expectation before they left. I highly recommend their work ethics and how they made me feel listened to of my concerns and made them answered to my satisfaction. Weather pro windows and doors is a company I can trust and so you can! I love my new windows!
Great team, with hard-working, fast, and efficient workers! Decent price as well!
Had a great experience with WeatherPro installing three doors in my home. Ian and his guys were very professional, friendly, and super knowledgeable. They took the time to walk me through the whole installation process and clearly answered all of the questions that I had. The quality of the work is excellent, and I’m really happy with how the doors turned out. Everything looks and works perfectly. I would definitely recommend WeatherPro to anyone looking for top notch service and craftmanship!
We are very pleased with our windows and doors that we had installed about a month ago. Dealing with with Weather Pro was very easy, from their sales rep., to the installation crew we never had any problems. The installation crew was not only efficient, they did a great job of cleaning up after themselves.

How much does window replacement cost in Calgary?
Cost depends mostly on the number of windows, the styles you choose, and glass upgrades such as triple pane. Typical Alberta projects range from around $12,000 for a small home to $35,000 or more for a large one. A free in-home consultation gives you an exact, itemized price for your home.
What windows are best for Calgary winters?
Triple-glazed windows with insulated frames and a tight, properly sealed installation perform best against Calgary’s cold and Chinook swings. ENERGY STAR-rated units designed for Alberta’s climate zone are a reliable benchmark.
Will new windows lower my heating bills in Calgary?
New windows reduce heat loss, and the savings are largest when triple-glazed glass, an insulated frame, and a sealed install work together. Actual savings vary by home, existing insulation, and the condition of the windows being replaced.
How long does a window replacement take in Calgary?
Most residential projects are completed within one to two days, depending on the number of windows and the condition of the openings. Larger projects may take longer, and your crew will confirm the schedule in advance.
Can windows be installed in winter in Calgary?
Yes. Our crews install year-round, using methods that limit how long each opening is exposed. Many homeowners replace failed units before or during winter when drafts are most noticeable.
Do you offer financing for window replacement?
Yes. Options include new windows starting at $49 a month and a 0% APR term for 6 or 9 months, both available on approved credit through Financeit. A specialist can walk you through the options during your consultation.
Does Weather Pro serve my Calgary neighbourhood?
We serve homeowners across Calgary and surrounding communities within a roughly 35-mile radius, including Varsity, Brentwood, Silver Springs, and Lake Bonavista, as well as nearby towns like Airdrie and Cochrane.
Are vinyl windows a good choice for Calgary homes?
Yes. Vinyl windows in Calgary are popular because the material resists warping and rot during freeze-thaw cycles, requires no repainting, and provides good insulation against winter cold. Paired with triple-pane glass, vinyl windows keep energy costs down and last for decades.
