Our Reputation is built on Trust and Quality


The company salesman was great rep. He provided all necessary information and facilitated us applying for the government-sponsored interest free loan.
Fourteen windows where quickly changed by competent, knowledgeable and courteous workers. They answered all of our questions and looked after any worries we might have had. The complicated metal sheet flashing of all the windows in our mansard-type roof was done very well. Everything looks great and the house already starting to feel warmer. No cold is felt on the hands when in contact with the vinyl of the windows and very little when on the triple pan glass. Thank you so much to all of the Big City Windows & Doors staff for a job well done.


Weve had nothing but the absolute best service from Big City Windows. They redid all the windows and doors in our heritage house, and we werent easy clients! My dad was in the business for many years, so we had a detailed list of what we wanted and high expectations for how it was to be done Big City installed everything a month ago, and my dad is still singing their praises! Everyone who comes to the house, even strangers, remarks on how gorgeous our new front door is!


Did an awesome Job installing the windows. No major issues. The windows were Installed and ain a timely fashion..they cleaned up after themselves. This is the second time we have used this company.


We recently purchased a older home, Big City Windows helped us with redesigning the whole thing! They really go above and beyond for their clients we could not be happier with the results.

Our doors are showstoppers and the windows keep the house soo warm in the winter. We were hesitant about having them installed during the winter winter months but it was totally worth it- We were feeling the difference instantly!

We highly recommend Big City Windows for your next window project!


We are very satisfied with the work and expertise of the staff who handled our contract. From the sales agent, to the person who took the measurements and to the two installers, everyone was professional and respectful. The installers were perfectionists, their work was excellent. We will share your company.


I had Big City Windows replace a patio door and a large living room window, through a recommendation from our neighbour. Well from the start of the process, to the finish. I couldnt be happier. The quality of work was next to none, the quality of the materials used were amazing The 2 employees were great!! They arrived first thing in yhe morning and worked their butts off till the job was done. My wife and I are completely satisfied!! They left a clean work place when they were done.


It was a seamless experience getting my windows, and patio door replaced with Big City Windows. Timelines were met. The window installation team was professional, and I was very impressed with the work they did.


Employees were helpful at all stages: from check measure, purchase, delivery and installation. Received the patio doors in the time indicated. Installation was professional and clean up was amazing! Their pricing was great! I would recommend Big City Windows and Doors for anyone that is looking for this service. You will not be disappointed.


Big City Windows and Doors is by far one of the best companies with which we have dealt. They took the time to look over our project and come up with recommendations that met our needs.
We had a new side door and door from the house to the garage replaced. We really like the new self closing hinges on the door to the garage.
The installation team was amazing. They took even the smallest detail into account when finishing up the install. You would have never known they were there.
We're already saving towards replacing our front door to make a matching set.
They will be getting our business for the foreseeable future for sure.


Very happy I was shown different windows styles. We went with the larger pane and smaller opening window. It's like looking through a clear opening. We have a big bushy backyard, so nice to see it so well. I actually had a couple deer come peek all I could see were these big ears in the dark. Our windows are lower. Also went with vinyl them. There easy to wash and remove when painting around them.
The installers were also fantastic, they even re-adjusted our front door from last march 2023 without my asking.
Thank you very much.


Frequently asked question about Window Replacements in Ottawa

How Much Does Window Replacement Cost?

The final cost of your window replacements will be determined by the exact specifications of your home, from its structural needs to your energy-efficiency requirements in our Ottawa climate. Their dimensions and quantity will also make a major impact on your total cost.

Regardless of the type of window you choose, newer, more energy-efficient windows can raise the value of your home in a way that few other kinds of home upgrades can match.

For a quick estimate of your total window replacement cost, click here for our guide.

Is Big City Windows & Doors a Window Manufacturer?

Yes, we are! As an industry-leading window replacement company, we at Big City Windows & Doors manufacture vinyl windows to fit the exact needs of your home.

Does Big City Windows & Doors Offer a Lifetime Warranty?

Yes, we do! Big City Windows & Doors provides a lifetime, fully-transferable warranty on all of our windows - if your Big City windows ever need servicing or repair, we’ll be there to help.

What Advantages Does Triple-Paned Glass Offer Over Double-Paned Glass?

Both triple-paned glass and double-paned glass contain an inert gas between their panes called Argon. Argon gas doesn’t conduct cold or heat as well as regular air, making it a great insulator for your home as it keeps your indoor temperature stable.

Double-paned glass has one layer of Argon between its two panes of glass, while triple-paned windows contain two layers of Argon between their three panes of glass. This increase in Argon gas between frames amplifies the R-value of your windows, meaning the energy passing through your window is nearly zero, and your home loses virtually no heat or cool air.

What Materials Are Your Windows Made of?

Our windows are made from unplasticized polyvinyl chloride, also known as uPVC. Unplasticized polyvinyl chloride is similar to regular PVC in that it is also used for its resistance to moisture and durability - however, uPVC is even more durable than PVC, making it ideal as a high-quality, low-maintenance choice of material for your new windows.

In general, one of the strongest features of uPVC vinyl windows is that they require very little maintenance, and can be made in a wide selection of colours and styles.

Do I Qualify for a Greener Homes Grant Rebate If I Buy New Windows?

Yes, you qualify for the Greener Homes Grant rebate if you purchase our high-quality LOCKTIGHT™ windows! To see if your replacement windows qualify for the grant, just ask a Big City Windows & Doors expert.

What Type of Window is Most Energy Efficient?

Generally, hinged-sash windows, along with casement and awning windows, are considered to be the most energy-efficient styles of windows, due to the reliable, weather-tight seals they create when closed.

In addition, fibreglass-framed windows can offer your home the highest window R-value on the market, thanks to their triple-paned glass and Low-E coating capabilities.

Beyond these options, other energy-efficient types of windows include vinyl windows, along with composite-framed windows built with double-paned glass.

How Often Do You Need to Replace Your Windows?

Every 15-20 years or so, new window technology emerges in the Canadian market, making newer replacement windows that are more efficient at conserving energy an economic advantage for your window replacement project.

According to industry experts, replacing your old, drafty windows and doors can help you reduce your home energy bill by as much as 25% - but only if they are professionally installed by experts who know what they are doing. Luckily, Big City Windows & Doors is here to help - if you’re ready to get started on your window replacement project, just click here to discuss your project with a pro.
