Comfortec Windows & Doors Reviews

homeowner, Hawkestone

says on Homestars
I needed to replace a huge window in the living room. Comfortec did an excellent job, doing project in a shortest possible time. Price was very competitive, installers came as agreed and the window was installed. They cleaned up after themselves and even adjusted my blinds to fit a new frame! Very impressed and highly recommend the company.

cashleigh, Toronto

says on Homestars
I would highly recommend this company. Igor came to my house and talked me through what needed to be done for my very old doors. He explained everything to me and gave me options I didn’t know existed. His knowledge and expertise was so valuable in making my final decisions. The guys came to install on time and were polite and efficient. I could not be more happy with how my doors turned out. I will definitely be calling them in the future when I need windows done.

Customer, Vaughan

says on Homestars
They refinished the outside of my main doors. They very professional, reliable, meticulous in their work and ended up with a very high quality finished product. I highly recommend Igor and his team.

Customer, Toronto

Igor came to provide a quote. His prices were reasonable, and he did not pressure us to purchase. The installers arrived on time, they worked quickly and cleaned up after themselves. They checked to make sure we were happy with the work. After they left, Igor also followed up to ensure we were satisfied. Overall we had a great experience and would purchase from them again.

Customer, Toronto

says on Homestars
I couldn’t be happier with the results. Comfortec Windows and Doors has exceeded my expectations. Igor the owner is down to earth and makes decisions making less stressful. Dima and other guy who did the installation were professional and paid attention to detail as well as cleaning up before they left. Would not hesitate to recommend.

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.

Lilli, Toronto

says on Homestars
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.

Customer, Toronto

says on Homestars
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!
