We are happy with how our windows turned out and the service that Comfortec provided during the process. We changed 10 windows including our rear and basement windows. We originally had white aluminum windows and went with black painted vinyl windows from Vinyl Pro. The windows really updated the look of the house and brightened up how our red brick colour presents. Our installation date was the third week of October, 2020. Igor, the owner and sales person of the team, had great communication from beginning to end. His response time was prompt and he was very knowledgeable about his products. He answered any and all inquiries with a quick response time. His demonstration was professional and did not use high pressure sales tactics. Comfortec was the first company we had quoted and Igor was very confident that he would win our job after we had done our diligence and quoted other window companies. Once we had chosen Comfortec and finalized the job, the installation date that Igor originally estimated was accurate from the beginning. The installer came immediately to measure the windows the same week once the contract was signed and the deposit was given. Igor showed a willingness to go the extra mile and he proved it to us. Within three weeks of the installation date, we requested a significant change to the configuration of one of our windows. Igor went above and beyond the normal call of duty to ensure our change could be accommodated, despite the windows having already been manufactured and sent to the paint facility. We can't even imagine the disruption this had caused their manufacturing and painting lines. This was but one of the few examples during our experience that solidified our approval of the company. The installation team was punctual and diligent. They installed ten windows during inclement weather (cold and rainy) and faced unexpected obstacles due to the build of our house, which was build in 1964. They arrived at 8:00am and worked until a couple hours in the dark, finally leaving at 8:30pm. The installation crew was a group of three people with a variance of experience across the team. Two were clearly experienced whereas one was new to the window installation industry. All the installers had a strong attention to detail and were very picky with their workmanship. It felt as though they were installing the windows in their own home. While the job could not be completed in one day as expected because of the unexpected challenges, the installers completed the rough installation of the windows and cleaned all areas before leaving. They returned within the week to ensure the job was done to its entirety (finishings, mouldings, and exterior caulking). They paid attention to each window and cleaned up all the garbage and excess materials. Obviously, it is too early to say how long the windows will last but if there are any problems within the warranty period (25 years for frames and sash, 25 years for workmanship, 15 years for sealed glass), we are confident that Igor, Comfortec, and Vinyl Pro will stand by the warranty. Overall, we had a great experience from start to finish. Thank you to Comfortec for a job well done. I would hire them again to potentially replace the front windows, entrance doors, and patio doors of my house in a few years.

We were referred to Comfortec Windows and are thoroughly impressed by Igor and his team for their professionalism, quality of product and workmanship. We met several others but either their product or price or quality didn’t match but with Igor and his team it was a perfect blend of all. We highly recommend Igor and his team for a job well done.

Maurizio, Vaughan

says on Homestars
Great work and costumer service. I had Comfortec replace my front door last year and they did such a great job I called them this year when I needed new windows in our master bedroom. We're very happy with everything from the customer service to the quality of the windows. We will definitely go back to Comfortec in the future.

Customer, Toronto

says on Homestars
We are very happy with the quality and service provided by Comfortec. Igor explained our options thoroughly. Communication was prompt and pleasant. Sergey and his assistant did a great job installing the new door with the challenges of an older house. And the cost was very competitive. We have no reservations about recommending Comfortec to anyone.

Igor Zask was easy to communicate with and gave good advice regarding our basement windows. The price was competitive, compared to some other companies we contacted. Overall we are satisfied.

Jeff, Old Ontario

Comfortec was able to install the windows several days before initially anticipated. Igor came through from start to finish, following up and ensuring the installation of a pristine final product.
