Comfortec Windows & Doors Reviews

I was shopping for new windows to replace my original ones. With COMFORTEC I have exactly what I wanted for a reasonable price. I replaced all 8 windows and a sliding door before winter came. The product and service were outstanding and we feel the difference in terms of thermo- and sound insulation. The installation had been done within a single day. It is done professionally satisfying such a picky person like me: decent amount of internal and external insulation, nice finish around the frames and no rubbish left after the work done. The windows are made of non-recycled material and look very nice from the inside and outside. The insulation level is really impressive: during the winter day, when furnace is switched of, the temperature goes down only 1 degree! We saved significantly during this winter. What's more, the window itself made with double glass, each one with different thickness. We do not hear a sound of a landing planes anymore! The bottom line is, Comfortec was the most competitive among other quotes. You can get a very good product, enjoy for long years to come and not go bankrupt.

I needed windows and doors for my house extension and to change the existing ones. I shopped around and I also asked my daughter about the company that did hers, when she built the new house. She recommended Comfortec for doing an outstanding job. I chose Comfortec, too, based on the quality of the product, the quality of service, and price. I was very happy with my choice. I got the windows and doors I liked for a very good quality and a good price. I was impressed by Igor's professionalism. We could discuss to make the best choices and he delivered my order as promised. The product quality was impeccable and the service was exceptional from the beginning to the end. I highly recommend Comfortec for exceptional service at a good price.

We were looking to replace windows and sliding balcony doors in an apartment building. The estimated price was very reasonable. The process of taking site measurements was quick and accurate. The production and delivery time was exactly as per agreed upon schedule. The installation crew provided a fabulous work. Very quick, with high quality. All tenants in the building were pleased with the results. All windows and doors were installed in 3 days with minimal disturbance to tennants

Comfortec staff were very friendly, and they delivered exactly what we discussed, quickly and without disturbing us in our home too long. Good craftsmanship and definitely worth the price to get better quality. We will probably never have to buy windows or doors again but we would come back. Thanks guys!
