Comfortec Windows & Doors Reviews

Customer, Caledon

says on Homestars
Igors presentation was very informative. The work was done quickly and efficiently. The guys that came to do the installation were hard working and polite. I would recommend the work and the product to anyone looking to change windows and doors.

Igor’s presentation was impressive. He kept us informed about the ongoing status of the job. Peter and his crew were punctual and courteous and did a skillful job installing two patio doors and two windows. Peter came back the following week to install the missing kick locks. One of the screen doors wasn’t closing properly so Igor sent Peter again and he worked until the door closed smoothly. I was pleased with Igor’s professionalism. He and his company take pride in their work and I would definitely recommend Comfortec.

I believe everyone knows the stress related to the major renovation. We are renovating our semi-detached house, and hire Igor Zask and his team to install the windows into the entire place. We are very highly satisfied with the quality of their products and services! They didn't only install the windows but also helped us to save the wall on the first floor when bricks unexpectedly started to fall down. We would definitely recommend Comfortec to those who are looking for a supportive team of professionals. Thank you guys for a great job!

Repeat customer. We replaced 13 windows last year and we very happy with the quality of product, price and installation. Didn’t hesitate to call them back to replace another 7 windows this year. Igor Zask and his installers are professional, hard working and do a great job. They took great care to protect our house and furnishings and cleaned up all the work areas when they were done. We highly recommend him to our friends and family.

Dana, Markham

says on Homestars
Excellent workmanship, timely communication, very professional and reliable. Deadline sharply met. Most importantly, great customer service skills. I much appreciate that, especially after dealing with another company first, which provided me with the headache of the opposite experience. Thankfully, that lead me to finding Comfortec who did the job to my satisfaction. Their price was much lower than the competitors. I will recommend them to all my friends.

Customer, Markham

says on Homestars
Repeat customer here. The doors are beautiful, installation was superb and completed within hours. Installers were very professional and cleaned up after themselves. We would like to thank Igor Zask and his team for a great job! And we would highly recommend them.

Comfortec - highly recommended by its' customers and really lives by its reputation. At the time of the emergency, they gave professional advice and promptly delivered the product. Every step of the way was exactly as discussed. They went above and beyond exhibiting true work and dedicated workmanship.

Vlad, Mississauga (ON)

says on Homestars
Ihor (the owner) matched and beat the competitor quotes by far, so we went with his product. The installers were on time and they were very professional, working in the coldest days of January with temperature reaching -10 C. Our entry door (fiberglass) is very beautiful and worth every penny. We are very happy with our new door. Thank you Ihor and team for your job!

Thilani, Toronto (ON)

says on Homestars
We needed a exterior door install completed within two days to alleviate our existing GC from scope of work to get a project done on time. Igor got back to me within an hour and had a guy ready to come the same day! It was amazing and great communicators. We needed Igor and team to come back because the door settled and temperature/humidity changed and the lock needed to be adjusted. They did it the same day I called. Amazing guys thank you so much! Fast and efficient. I would use you again!
