Product and service are unmatchable.

This review is long overdue for installation in 2015. I had them put a window where there wasn't one before. I am very particular and not often liked by installers because of my fussiness. This installation was immaculate. I would definitely recommend them.

Sliding Door Screen Replacement

We had a retractable screen on our patio door that was not working well, and having issues with the patio door being heavy and difficult to slide. Sean was very honest, knowledgeable and did not try to sell us anything. We ordered new sliding screen door to replace the retractable screen. He did a great job installing a new door and did not charge us anything for the patio door assessment. The delivery was a little delayed on the screen door due to the manufacturer, otherwise our experience with Sean was great. By comparison, we had another company from Homestars come out and try to sell us a new patio door.

Unbelievably Good Service and Workmanship

We simply cannot rave about Sean and Koper Windows enough. We needed our outdoor porch screened in and were having a difficult time finding someone who could understand what we were looking for. Sean arrived when he said he would, took a look at the project, figured out a solution and went straight to work. Punctual, accurate, skilled and a pleasure to work with--that is Sean in a nutshell. He did a wonderful job! Our only complaint is that we didn't know of Koper Windows at the beginning of our renovation. We wouldn't hestiate to recommend Sean and his team. Exceptional work!

Condensation on Sky Lights

I would highly recommend the services of Koper Windows & Doors. Sean performed a repair on my skylights quickly and professionally. He went above and beyond to get to the area that needed to be repaired and even cleaned the windows afterwards.
I loved being able to support a smaller local company that has been in business since 1986. I will also use this company to replace windows later this year.

Windows installation

I am very pleased with the work completed by Koper Windows and Doors. From the time of getting a quote from Sean to the completion of installing windows was a smooth process. All my inquiries were addressed. The installers (Tom and Paula) arrived between the specified time and explained what would take place. They were professional and tidy. My compliment to the team. I highly recommend Koper Windows and Doors and will definitely use their service again.

New windows for a 2 story house including covering of wood trim with aluminium.

Over a 2 day period 20 windows were replaced with the utmost care and precision. The installers were professional, clean, polite, expert, knowledgeable and always concerned that they did their best work. The company representative made suggestions as to the window style and colour. A great assistance because a home owner purchases windows rarely. An excellent experience on all counts. Highly recommended!

Whole House Windows and Entry Doors

Choosing Koper Windows and Doors was the best decision we made. The windows and doors are made by KV Custom Windows and Doors, which is a fantastic product, and made here in Vaughan.

From the initial consultation, to the installation, Sean, Tom and Paula were always punctual, professional, courteous, clean, and most of all, they delivered! The final product exceeded our expectations, and we would highly recommend that you meet with Sean at Koper Windows and Doors before you make your final decision.

Window glass replacement

Sean fixed the broken window glass for us. He gave us the quote and was extremely detailed in explaining the installation process, the types of windows available, color options, and what to expect (in terms of work involved, timeline, end product expectations, considerations when selecting windows, and work required on the homeowners end). Overall the fixes which he made were near and tidy.
