“Masters of their trade”. Frank and his crew did an amazing job installing 13 windows and 1 door for us. The installation, the framing and the clean up, everything was top quality. I would definitely recommend this company.
These guys are fantastic. I was recommended to them from a friend and I am so happy I went with them!

Greg’s window philosophy.
Greg’s the main guy around here at the Concord Window Store. He started this business after spending years learning all he could about windows and doors. Greg saw the opportunity to do it better, to do it right, and to help more homeowners realize their dream of a beautiful home. As he says, there’s more to this than meets the eye…
“A perfectly architected and designed home can be ruined with the wrong choice of windows, or a mis-proportioned entrance. Your windows frame your home, serving both the functional purpose of delivering light and fresh air, and the decorative purpose of unifying your home’s design.”
Colours, wood textures, glass technology, sills, paneling and transoms are just a few of the many factors that we will help you carefully consider when designing your home’s ‘face to the world’.
Customer Reviews

He took pride in his work and the finished product attests to his skill. We could not be happier with the quality and look of the windows and the efforts of your team.
Your work has really transformed our home. Our new windows keep our home warmer in the winter, and quieter in the summer. From beginning to end, your team was a pleasure to work with. They showed up on time and delivered exactly what we expected. We’re delighted, and can’t recommend Concord Windows & Doors highly enough.

I needed a glass panel replaced for our porch enclosure and Academy Glass was able to get the job done perfectly. They were very helpful over the telephone and asked me all the measurements. Once I went into the store the glass was cut and mounted in the frame in under 15 minutes. I can now enjoy the glass porch enclosure.
Great service and quality work. They provided me advice on what’s best for my home insulation. The pricing is reasonable and I am very satisfy with they delivered. Will come back again for other glass products and refer to friends.

Just a small job I had to replace a single window and a broken concrete sill. Not many companies wanted a small job or would work with concrete. Royal quoted me the job no problem and today George the installer and his helper were great. Clean, friendly, on time, and great quality workmanship done with care. I will be using them again in the future.
In my past experience with Windows & Door companies, they usually over-promise and under-deliver. These guys were the opposite. They installed the windows exactly when they said they would and the work was done fast and well. Thank you….we will use you again!

FAQs about Window and Door Services in Toronto
How long does window installation take?
Many window replacements or installs may be performed in a single day, or even in a matter of hours. This, however, is dependent on the number of installed windows and the amount of complexity that the windows exhibit. It’s preferable to budget for two days.
Is it more cost-effective to replace broken glass or a whole window?
If there are no other issues with the window and only the glass is broken, replacing the pane makes more economical sense. If the window is old and out of date, or if it is inadequately insulated, replacing the complete window will save you even more money.
How do I choose a window style?
Personal tastes usually impact the selection of window types such as double-hung, casement, or sliding windows. It is crucial to remember, however, that certain window types may be hard to install depending on where you want your windows installed. To establish what is best for you and your house, it is important to talk with a window specialist.
Should I replace my windows all at once?
If you wish to replace your windows for aesthetic or energy-efficiency reasons, replacing them all at once can offer substantial advantages. Larger operations like this are typically less expensive since you can combine many of the costs of a window replacement and frequently receive fantastic offers on purchasing a large number of windows at once.
Do workers have to come inside to replace windows?
Typically, the installer will be required to work both inside and outside of a home. Make sure to notify the personnel that you will let them to enter your home if you will be gone so that the installation may continue while you are away.
How do I prepare my house for replacement windows?
What you should do is as follows:
- Make a Way. Installers will enter and exit your house on a regular basis, moving from room to room.
- Window treatments should be removed. Next, remove any curtains, sheers, shades, or other items that enclose the windows.
- Place dust covers on the floor.
- Energy should be conserved.
- Allow them access.
