Have you been enduring an uncomfortable draft near your window for some time? Maybe it’s high time you called the top window repair service in Ottawa to get it fixed.

And if you want to know more about the process of window repair or replacement, our handy FAQs at the end of this listicle should sort you out.

How Much Is Window Repair in Ottawa?

Several factors can determine the final invoice of a window repair service in Ottawa. The biggest one has to do with the type of installation involved.

Full-frame installation means your old window will get completely taken out — frame, screws/nails, and all. This is usually done for windows that show rotting, moulds, and moisture issues.

But if it’s a retrofit installation to be done, it will significantly cost less than a full-frame one (around 10% – 15% cheaper). Your current window frames won’t be removed but would have new windows inserted into them, instead.

Of course, details like the size and number of windows that need repairing, their location, what kind of house or space they’re in, and the material used will influence the final price.

To serve as an approximate price guide, here’s a table of window sizes and their estimated costs (based on national averages).

Small$450 – $1,500
Medium$620 – $2,800
Large$1,150 – $3,400
Extra-large$2,000 – $4,000

Other factors could come into play when it comes to repair and replacement costs (such as labour fees). It’s best to get a quote from a reputable service provider first or use their online estimate calculator.

1. Marlboro Windows and Doors

Marlboro Windows and Doors
SERVICESFull-service window and door manufacturer, installation, service, delivery, sales consultation and full project management large or small
ADDRESS2370 Stevenage Drive Ottawa, Ontario, Canada K1G 3W3 
CONTACT NUMBER613-736-1441
[email protected] 
OPERATING HOURSMonday to Friday 8 AM – 5 PM
Closed on Saturdays and Sundays

Since 1976, Marlboro Windows and Doors has been a full-service family-owned manufacturer of windows and doors. That means it builds, sells, installs, and provides warranties for all of its clients.

It’s gotten a Better Business Bureau accreditation (Aᐩ rating) for it, aside from consistent feedback about its efficiency and the quality of its products. It serves residential, commercial, and new construction clients minus the middleman fees of other companies.

Marlboro Windows and Doors carries ENERGY STAR products that are built for even the harshest Canadian climate zones. This kind of energy efficiency is welcome but it would be great to have some base pricing information to work with.

And it would be good to have a client portfolio or gallery of past works for practical application inspiration, too. At the moment, the images come off like a catalogue.

There is a window configurator that allows potential clients to choose the type of window system, material, colour, and grille needed for installation. However, a free quote form is required to get the estimate (which is a bit anticlimactic after using such a handy tool).


  • No middleman fees
  • Serves residential, commercial, and construction clients
  • Window products meet Energy Star requirements
  • Gives free quotes
  • BBB-accredited, Aᐩ rating


  • Open only on weekdays
  • Doesn’t provide a pricing guide
  • No client portfolio or gallery

Customer Reviews

The installation team is competent, clean, and polite

“I chose Marlboro Windows and Doors to do three separate installations at my home over the past three years. They replaced floor-to-ceiling windows in my living room and two large patio doors and then 5 large windows (some sliding) and just now two large sliding basement windows and three smaller windows. Their installation team is invariably competent, clean, and polite. The people in the office listen and are responsive quickly. The experience has been very positive from every angle and I strongly recommend them to anyone seeking quality windows and high-quality installers. You won’t be disappointed!” – Harry Qualman

Great product, fast, efficient installation, good prices

“Great product, fast efficient installation, good prices. They did my entire condo community – and all were very satisfied.” – Donna Lowes

2. Capitall Windows

Capitall Windows
SERVICESWindow and doors sales and installation in Ottawa/Gatineau
ADDRESS2212 Gladwin Crescent‎, Unit A3 Ottawa, ON K1B 5N1
CONTACT NUMBER(613) 680-0492

OPERATING HOURSMonday to Friday 8 AM – 4 PM
Saturdays 9 AM – 11 PM
Closed on Sundays

Capitall Windows has been in the windows and doors sales and installation business for over 15 years now. Since 2010, it’s also had an Aᐩ rating from the Better Business Bureau. 

There’s a wide range of window options at Capitall that includes casement, awning, single or double-hung, single or double slider, fixed, bay and bow, and other types. There are also ENERGY STAR certified products available.

If you want to see what the company has done for its clients in recent times, there are great gallery pictures to peruse. They just lack captions and information that can give people an idea of the products or services utilized.

The company offers a free on-site home estimate for its clients. To sweeten the deal, Capital has a 0% downpayment option and payment plans for as low as $95 a month.

We’re also quite impressed with the warranty that comes with its products and services. There’s a lifetime warranty against defects for rigid UPVC window frames and sashes, as well as for all hardware and the craftsmanship for all its products (upon the date of installation). 

Perhaps the only thing that’s lacking with this company is some base pricing information on each type of window and service. Even an estimate calculator tool would’ve been nice.


  • Monthly payments available
  • Gives free quotes
  • Lifetime warranties for products and labour
  • BBB-accredited, Aᐩ rating


  • Gallery photos don’t have captions
  • No price guide provided
  • No estimate calculator is available

3. Centennial Glass

Centennial Glass
SERVICESResidential and commercial window and glass repair, custom fabrication, screen repair, parts and hardware

CONTACT NUMBER613-738-9500
OPERATING HOURS24/7 emergency repair available
Monday to Friday 8 AM – 5 PM
Saturdays 9 AM – 4 PM
Closed on Sundays

We believe that emergency services shouldn’t be confined to healthcare, especially for matters that have to do with your home’s security and safety. That’s why we’re happy to feature a Better Business Bureau-accredited glass company that also offers 24-hour emergency service.

Centennial Glass was founded in 1967 and serves both commercial and residential clients with custom fabricated glass products and contractor services. It can accommodate emergency repairs on any glass components of buildings or houses.

We also like that Centennial Glass has a dedicated menu for repairs and services aside from being a supplier of windows, doors, and screen parts. And while it can do window and home glass-related repairs, the company is careful to mention what it can’t do (which is a helpful guide in emergencies).

There’s also a live chat with a customer service representative for your questions on costs, repairs, custom products, and the time it will take to finish. 

This feature is especially helpful since there’s no price guide for any of the products or services, though a free quote form is available.


  • 24/7 emergency repair services are available
  • Live customer service chat
  • Dedicated repair services
  • Gives free quotes
  • BBB-accredited, Aᐩ rating


  • Can’t repair appliance glass
  • Doesn’t provide a service or product price guide

If you’re thinking of upgrading your home’s windows to ENERGY STAR-compliant products, you can try out CANA Windows and Doors. It’s Ottawa’s first registered dealer to offer these energy-efficient alternatives as well as other eco-friendly products.

It’s another BBB-accredited company that carries Canadian-made windows and doors. Potential clients can request a no-obligation in-home consultation for any of its products and services.

There’s a wealth of information on the different types of replacement windows it carries, including what makes their coating and features environmentally sound. However, there’s no base pricing information or even an estimate calculator to use, so asking for a free estimate is the logical step.

And while CANA Windows and Doors has a physical showroom, it’s currently on a strictly by appointment visiting basis. Hopefully, this means weekend appointments can be accommodated as regular operating hours are confined to weekdays only.


  • Free in-home consultation
  • Helpful information on replacement windows

OPERATING HOURSMonday to Friday 7.30 AM – 4.30 PM
Closed on Saturdays and Sundays

“More bang for your buck” is the Verdun Windows and Doors promise. It encourages customers to upgrade to eco-friendlier windows as a way to maximize returns on investment under the Canada Greener Homes Grant.

Another thing we like about this company is its “No-Bull Warranty” for all of its products and services. It covers all products, installation, hardware, and labour for 25 years with no fine print clauses to deal with.

There’s a virtual catalogue of replacement window types on the website with comprehensive information on each one. The company breaks down the components, construction, eco-friendly features, colour and grille options, energy-efficiency ratings, and even glass finishes.

Verdun Windows and Doors gives three helpful payment options for customers. They can choose to defer payments three months after installation, go for 60 equal monthly payments, or opt for an open plan that allows them to pay it off in full at any time!

But while it offers free quotes for potential clients, it would be nice if they threw in some base pricing information or a calculator tool, as well.


  • 25-year warranty on labour, parts, and products
  • Gives free quotes
  • Payment plans available
  • Complete information on window types and features
  • BBB-accredited, Aᐩ rating

OPERATING HOURSMonday – Friday, 8 AM – 5 PM

If you’re looking for a window repair service provider who can attend to your emergency needs, then Grizzlie Glass is the one for you.

The best thing we loved about them is that they’re really prompt with their services, and you can expect a fast service once you contact them. The only catch is that they’re only open during weekdays, so they can’t help you during your weekend emergencies.

We’d also like to mention that they specialize in commercial installation, the window designs they offer for residential properties look great too.

Their personnel are also commendable for having a great sense of style when choosing designs that beautifully transform home exteriors. If you want to replace your windows but you’re not sure about the style, then you can trust Grizzlie Glass to help you out with that.

They also have decades of experience in the industry, so you can trust their network of skilled professionals to get the job done.
