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!

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.
