On Star Windows & Doors

We chose this company over several leading companies in Toronto. The best quality and price. The job was done super fast and professional. Special thanks for help with design. Strongly recommended.

They installed a sliding door in my home that allows water into my home when you was the glass...even the mechanicals on the windows are not even a year old and already rough and not easy to wind open or shut they damaged walls install my upstairs windows and even installed the wrong size of jambs upstairs different from all of the other windows that they installed for me also the installed a screen door that had a rip in it vlad told me he would come back in a month and install a new one and never did this company has to be one of the worst window companies in my opinion

My mother hired this company to install 5 windows and a patio sliding door in her home. Vlad was very professional and provided excellent service. My mother is very pleased with the work that was done. We would highly recommend this company. Thank-you very much.

Vlad was quick to come and give the quote and worked around my schedule when I had to make a last minute change. During the quote process he made some good recommendations that we're very happy with. The installation was very professional. They came when they said they would, did a great, clean and professional installation. I'm very happy with the result. Much better than the rest of the windows in our house.

I needed to have all the windows replaced in my home. I shopped around and got/asked for quotes from multiple companies. Of all the companies, Vlad and OnStar windows gave me the quickest and most hassle free quote. Furthermore throughout the entire process the entire team at OnStar I dealt with were very professional and courteous - extremely happy with the installation and quality of the windows. Vlad made some suggestions during the quoting process regarding what style of windows to get, and I must say they were very good suggestions, transformed how the living space feels along with improved usability.

All the windows in our house needed replaced. On Star gave us an excellent quote. Not pushy and very informative. They know their Business. From the very start I was impressed. Installation was fantastic. Very fast and everything cleaned up. The windows look amazing, far better than I anticipated. I was extremely pleased. I would highly recommend this company to anyone looking for windows. Extremely Competitive pricing, Professional, Knowledgeable, very easy to deal with.and Excellent Product. Windows look so good I don't want to put any Window treatments on them. I'm just sorry 10 is the highest rating, as they deserve a 10+++++++.

Amazing job! I thought that would take at least half a day but less than 3 hours later I could enjoy my all new window. Unbelievable! Three professionals, punсtual, friendly, knowing what they are doing. Good size window - two sections double hanger now in the wall where was no window! Great job, thank you very much! Highly recommended!

We received prompt and courteous response from Vlad for estimate to replace windows and a patio door. Delivery and installation were completed at the estimated date. Vlad and crew worked professionally to complete the job in one day. They took care to protect carpets etc; and cleaned up after completion. Job well done and we are happy with the new windows and door.
