Comfortec Windows & Doors Reviews

Yasmin, Whitchurch-Stouffville

says on Homestars
Igor and his team were very professional and well organized. Igor helped us select a beautiful set of doors for our home and we are very pleased with their service. We would highly recommend ComfortecWD!

Sheila, Toronto

says on Homestars
We are so happy with our new window from Comfortec! Igor and his team were reliable, responsive and installed our main bath window in efficient time. We were able to customize the design with frosted glass, black grills on the interior and white on the exterior to match the rest of our home. We are so pleased with the result, giving us a good jump start to our bathroom reno!

Howard, Markham

says on Homestars
This is the second time I've worked with Igor and both times I've found him to be highly knowledgable, organized and professional. He listens carefully to the customer's needs, answers questions in detail, communicates promptly, and explains every step of the process. The job required two appointments and he and his team arrived when they said they would. The installers were efficient, courteous and neat. The doors and windows look good, open and close smoothly, functions as they should. (I'm anticipating quality performance in winter, and will revise this review if that's not the case.) Overall i'm very satisfied with the Comfortec - its quality, professionalism, pricing - and recommend Igor and his team without hesitation.

Glen, Mississauga

says on Homestars
We decided to replace the full front entrance of our home. Igor came as a referral through a close friend. He was prompt in responding to our call, very detailed and patient in helping us select the right door, color and design features. Installers arrived on time and cleaned up after they were done. We are extremely happy with the results and the front entrance looks like a new home. Would highly recommend Igor!

Customer, Toronto

says on Homestars
I had a window replacement from Comfortec, I had a great experience with the company. They are very professional and friendly. I am also satisfied with the outcome. I will definitely recommend this company.

Marissa, Toronto

says on Homestars
I ordered a new front door (with transom window), screen door and back door. I love the quality of the doors and especially love my rod iron red front door. There was an issue with my automated smart lock getting stuck when using the automated feature, but Igor sent someone back to make the adjustment and works well now.
