Lea Gagnon5 Best Window Replacement Pros in Montreal to Fix Drafty Windows
I’ve paid for enough window cleaning services to know when the problem isn’t the dirt anymore. At some point, even the best squeegee can’t fix drafts, foggy panes, or a room that feels like February indoors.
That’s when I started looking into the best window replacement in Montreal. With our winters, worn-out windows can make heating bills sting almost as much as the cold itself.
I compared local companies that handle everything from older Plateau homes to newer energy-efficient builds. If your windows are past the point of polishing, these are the crews worth checking out.
How much does a window replacement cost in Montreal?
Window replacement in Montreal typically costs $500 to $2,000 per window, including installation. A standard whole-home upgrade can run about $8,500 to $19,000.
Vinyl frames are usually the most affordable at $450 to $1,500 installed. Aluminum can cost around $700 to $1,500, while hybrid frames are roughly $1,100 to $1,700.
Fibreglass windows generally range from $1,500 to $3,000. Wood is another premium option at about $1,700 to $2,800.
For window styles, double-hung and slider models cost about $500 to $1,000. Casement windows are similar at around $500 to $1,100.
Tilt-and-turn windows usually cost $750 to $1,500. Larger bay or bow windows can reach $1,800 to $5,000 or more.
How We Reviewed
1. Vitrerie Starlight
Address: 651 Rue McCaffrey, Saint-Laurent
Contact: 514-447-9771 / 438-874-3131 (Emergency) / [email protected]
Hours: Monday-Thursday, 8 AM – 6 PM | Saturday, 9 AM – 3 PM
I like that Vitrerie Starlight doesn’t automatically make every foggy or cracked pane sound like a full renovation emergency. Their glazing-first approach can be handy when the frame still has some life left in it.
The Saint-Laurent team works on residential and commercial projects around Montreal, with services ranging from window glass to mirrors, showers, railings, and custom architectural pieces.
Emergency glass service is also available, which is reassuring when a broken pane decides to ruin your day.
They’re especially worth considering if you want a specialist to look at the glass before committing to a bigger replacement job. That could make them a practical call for older Montreal properties where keeping existing features matters.
The catch is their focus is much more on glazing than complete window-and-frame replacement systems. If you need brand-new frames or a major structural upgrade, you may need a more traditional window contractor.
Quick & Reasonable Winter Replacement
Had a large living room window pane crack over the winter. Starlight gave me a quick, reasonable quote to replace it. Their team came in to repair the work and did an excellent job. All in all, I was happy with every step of this process with them, could not recommend them enough.

Seamless Service for Commercial Clients
I had contacted Viterie Starlight to replace a damaged window for a commercial client. They were quick to respond, were very clear about the process, communication was great, and service was seamless. Jonathan provided great service. I would recommend them and hope to use them again in the future.

2. Timberline Portes et Fenêtres
Address: 946 Rue Bégin
Contact: (514) 999-5553 / [email protected]
Hours: Monday-Friday, 9 AM – 4 PM (by appointment)
Timberline Portes et Fenêtres has more than 30 years of family-run experience, which gives them some welcome old-school credibility. They work with polyvinyl chloride, wood, aluminum, and hybrid windows suited to Montreal’s demanding climate.
I also like that they offer European tilt-and-turn windows, which tilt inward for ventilation and swing open for easier access. It’s a clever option if you want something a little more flexible than the usual setup.
Their experience with heritage homes is another plus, especially in neighbourhoods where keeping the original character matters. And window warranties can run up to 20 years, adding a bit more reassurance to the investment.
The main catch is that showroom visits are by appointment, so spontaneous browsing isn’t really on the cards. They’re also closed on weekends, which may make scheduling trickier.
Stellar Expertise & No-Pressure Sales
We are renovating a condominium with full window replacement. Our experience in dealing with Kevin Luongo has been stellar. Kevin is all over his brief – knowledgeable well beyond general attributes, and always back to you same day with answers to questions and solutions to problems. Kevin generously shares the pros and cons of product selection. This information deck, together with Kevin’s service ethic, integrity and no-pressure sales approach, is a textbook example of how you build relationships first and customer trust and loyalty for the long term. Timberline’s highest-ranking customer satisfaction status is fully warranted.

3. Superior Windows & Doors
Address: 6830 Park Ave #420A
Contact: (514) 534-1170 / [email protected]
Hours: Monday-Thursday, 9:30 AM – 5:30 PM | Friday, 9:30 AM – 1 PM
Superior Windows & Doors makes a sensible pick if your old panes are letting Montreal winters sneak indoors. Their focus on energy-efficient vinyl windows can help improve insulation and cut down on pesky drafts.
They also offer casement, sash, and tinted styles, so there’s some flexibility if you’re after more than a basic replacement. I like that they handle residential, commercial, and office projects too, which gives them a fairly broad reach.
Their window options are geared toward comfort, low maintenance, and better year-round performance. That’s especially handy when you’re trying to keep both February cold and summer humidity where they belong.
The downside is the limited weekend availability, which can make appointments trickier for nine-to-five schedules. Friday hours also end early, so timing your visit may take a little planning.
Beautiful Installation & Timely Delivery
I was extremely satisfied with the windows and doors replacement completed by Superior. Their excellent customer service, timely delivery, and beautiful installation truly exceeded my expectations. The entire process was handled with the utmost professionalism and care.
I highly recommend Superior for anyone considering windows and doors replacement—you won’t be disappointed!

4. Portes et Fenêtres Porto
Address: 7290 St-Jacques, Suite 100
Contact: 514-484-6203 / [email protected]
Hours: Monday-Friday, 9 AM – 5:30 PM | Saturday, 10 AM – 4 PM
Portes et Fenêtres Porto has more than 40 years of experience, and that depth really shows in their heritage-focused work. I’d shortlist them for older Montreal homes where new windows still need to respect the original look.
They offer custom-built options in wood, aluminum-clad wood, hybrid, and polyvinyl chloride. You’ll also find Low-E glass, argon-filled units, and styles ranging from casement and awning to bay, bow, and double-hung.
What I like most is that they don’t treat character and efficiency as an either-or choice. Their ancestral-style window options are designed to preserve traditional façades while improving everyday comfort.
The catch is that Saturday hours are limited, and the showroom is closed on Sundays.
Craftsmanship You Can Trust Across Multiple Projects
We have trusted Porto on three separate projects to replace windows and our front door. We enthusiastically recommend their craftsmanship, customer focus and service.
I will call out one supply chain issue for a screen; however, this was not a big deal, and supply chain challenges are not uncommon these days.
Bottom line: Porto always delivered and made everything right, treating our home as if it was their own. Two thumbs up!!

First-Class Service Even 22 Years Later
Since July 2000, we have been a client of Alfredo Da Silva’s when we replaced all of the windows in our home. I contacted him 22 years later & still received his friendly, professional service. His company, Porto, is the best there is for an excellent product plus 1st-class service. I highly recommend them unconditionally!

5. Pella Windows and Doors Showroom
Address: 2020 St Regis Blvd, Dorval
Contact: 514-331-1055 / [email protected]
Hours: Monday-Friday, 8 AM – 6 PM | Saturday, 9 AM – 4 PM
Pella’s Dorval showroom is handy if you’d rather sort out most of your window project in one place. They handle everything from measurements and product selection to made-to-order windows and professional installation.
Their range covers vinyl, wood, fibreglass, and hybrid frames, with styles like casement, awning, sliding, bay, and bow. You can also explore triple-pane and ENERGY STAR options if better insulation is high on your list.
I like that the process feels more coordinated than piecing together products and installers separately. That can make a full-home upgrade feel a little less like renovation roulette.
The main drawback is simple: the showroom is closed on Sundays. If weekends are your only free time, Saturday may get busy fast.
Huge Renovation Handled Perfectly With No Surprises
We recently finished a very large renovation project where all our windows (35) and doors (4) were replaced by Pella. It was our first major renovation. We gave Pella a chance to come and see us. We were very impressed by their competency, kindness (empathy) and devotion. They took time to explain clearly everything (lots of details). We chose Pella and cannot be happier with this decision!!!. Everything went well; they explained everything ahead of time, and there were no surprises. The timeline and installation were respected. I highly recommend them and don’t understand why they don’t have 5 stars.

More Light and No Drafts for an Older Home
I recently had 15 windows replaced in my older “Quebec Style” home and am extremely glad I chose Pella.
The salesman, Roger, was very knowledgeable, not at all pushy, and explained everything clearly.
The work took 4 days and, for the most part, went well. The crew were pretty careful, and the clean up OK. A little more training is needed for those from Europe and new to this country.
I now have more light in the house, no draughts and the enclosed blinds are unobtrusive and easy to use.
The price was comparable to other quotes I received.
