Igor provided no-nonsense advice to upgrade my old, ugly and inefficient windows without pressure or science degree level complexity for why his windows are the best. His crew were courteous, skilled and conscientious about not trampling my garden. While the job was more complicated and took longer than at first thought, as is usually the case in old, downtown houses, the end results are beautiful, functional windows that are sure to last for years to come. I'm very pleased with my experience with Comfortec.All Reviews
