WHAT ARE CUSTOMER'S SAYING ABOUT US: 

1. Dear Andy, Just a short note to thank you for the wonderful job you did on our replacement windows. From the very first time we met you in your showroom, we felt very confident and comfortable with your sales experience. We were replacing a lot of windows but after checking out other window people, we knew for sure that we would go with you. Your work ethics are pristine and so professional. We would highly recommend you to other clients, so please do not hesitate to use our name as a reference. Dianne & Ted Houghton
2. I am sure that we are not the only homeowners out there trying to find a reliable, quality home improvement provider. We seem to experience more disappointments rather than successes. One definite success in the Durham Region is ACM Doors and Windows. Owner, Andy Illes and his staff have always treated us like we were their only customer. We had all our windows installed by ACM in our previous home in Oshawa and now, years later, we are almost finished having ACM replace all our windows in our new home in Whitby. For years we have relied on ACM Doors and Windows and have never been anything but extremely satisfied with quality and service. I would only hope that all home improvement providers were as quality conscious and service oriented as ACM Doors and Windows. Please feel free to use our names as a reference anytime.Larry & Karen Thomas
