Quality Workmanship
I wrote a review on BBB in which I gave this company a five star rating. Now close to a month later I am writing on their home page to repeat it. This company did a fantastic job. The difference from before and after is amazing. The outside noise is diminished considerably and the warmth retained in the home will save me a fortune in heating this winter. I have been parading neighbour's through my home just to show off the quality workmanship. My sister is jealous as she went through another company to have windows done and is still not happy especially after seeing what your company has done. Your customer service is wonderful. You gave an accurate time line from start to finish of the work to be done. The team doing the work were friendly and awed me with their skill. You call yourselves a small family owned company but I'll just bet your extended customer family is growing every day.
Big Thanks
Thank you for a wonderful experience: from John's sales visit, easy ordering, responsiveness, to a solid installation on time, and a very good quality job, including the finish.
Very Very Pleased
Very very pleased with the Canadian Comfirt job replacing windows in my home. Tidy work, no mess at all when they were done, worked hard and consistently to get the job done on schedule, were polite and friendly but just got on with the work and I was able to continue working from home. The windows and framing are great, so happy to see out clearly after years of broken seals and fog, ha!
