“We were very satisfied with Gary’s work on the garage and as we were looking to replace all the windows in our house asked Gary for a quote.
Gary was very helpful and provided good advice when we were selecting the style of windows to have install.
Gary was always punctual, courteous and friendly when working in our home. The installation was completed in a timely fashion and Gary addressed any concerns in a professional manner.”

“Just a brief note to express my gratitude for such a great job done in replacing my windows and door.
I appreciate your professionalism, your reliability, your courteous and respectful manner, and your attention to even the smallest of details.
I will highly recommend you to my family and friends!”

Thanks very much again!

“I am very happy with the glass you replaced in my front windows, so happy that when spring comes I think I will have you replace the glass in the two large windows at the back of the house. The low E glass seems to make a noticeable difference to the temperature of the house. . .
I was impressed by the fact that you gave me an accurate estimate and you did the work when you said you would and you did an excellent job. Thanks so much.”


“I am so pleased by the patio doors. There is already a different feel to the room. I like that they are practically invisible.
What a relief it will be this summer with fresh air coming in but no chipmunks, hummingbirds or dragonflies.
Your work is fabulous and you are a pleasure to deal with.
I will not hesitate to recommend you and you can use me as a reference. Thank you,”


“Just a brief note to let you know that we are completely satisfied with the windows you installed in our home. I would have written earlier but I wanted to give them a chance to handle some of the Muskoka winter weather and they have come through with flying colours. The installations not only improved the look of our home but the upstairs rooms feel warmer and are draft free. I would have no hesitation recommending your services to others as I found the cost resonable and your installation quick and professional.
Thanks again for the excellent service.”
