Comfortec Windows & Doors Reviews

Natalya, North York

says on Homestars
This is the second time we have used Comfortec Windows and Doors company. Last year we replaced old doors for new ones, this time we replaced the old window in our living room. It was another great job by this company. The installers were very experienced, polite and friendly. The work was done quickly, the guys left our place clean inside and out. We were very happy with the work done. Our living room is so much brighter and warmer now. We will definitely recommend this company to friends.

Comfortec Windows & Doors replaced a number of windows and doors in my home. Igor Zask and his team were very professional, efficient and a pleasure to deal with. Their products are of high standards and transformed my home into a dream come true. Stunning! I highly recommend Comfortec for window and door replacements.

Fantastic experience with Comfortec. They gave us amazing, efficient and affordable service from start to finish. In my opinion hard to beat the price, high quality of materials and excellent work. Measurements were taken the next day after an estimate was done, and within 2-3 weeks the whole job was done. Phenomenal customer service and great work. They made the process painless and easy for us. Crew was great during the installation - fast, professional, and cleaned everything up afterwards. Overall, a job well done all around. What a well-run company! I'd do business with them anytime.

Tony, Bradford

Had a great experience working with Comfortec. From the first visit, Igor took the time to explain everything, and gave us plenty of options. We ended up replacing all our windows and doors, and the house looks transformed. Workmanship was great. Comfortec was also able to enlarge a pretty small bathroom window, making it more than double the original size - something other window contractors wouldn't even consider. All this at a reasonable price. I would recommend this company to anyone without reservation.

We had a really old door on our garage, and Igor Zask and Comfortec did a great job replacing it. Would 100% recommend. Igor was great at following up, and sent the guys over to fix a few remaining things that I had pointed out. Overall very professional, and easy to work with. Great job.

Melissa, Toronto

Contacted Comfortec to replace an old basement window and address leaks in windows around the house. They provided excellent and timely service. Sergei and Igor were both extremely professional, knowledgeable and helpful. I would definitely recommend their services and will be using them in the future.

Juilee, Markham

says on Homestars
We were really happy to work with Igor. He took his time to walk us through his product, explain the different options we had, and work with us to achieve both affordability and quality in his product. The windows and doors look great! Thanks Igor.

Gabriel, Toronto

says on Homestars
Working with Igor and Comfortec was nothing short of amazing. Very professional team. Igor is a very confident person, and he took the time to explain everything to my wife and I so that we understand why we should go with Comfortec. Price was very reasonable as well. This project was definitely an "Under Promise, Over Deliver" by Comfortec. Any questions or issues I had were addressed right away. Would gladly recommend them to anyone. I will be connecting with Igor for future projects. Thank you and my wife is very happy, I guess that's what matters the most. Lol
