your Window and Door needs

Look To Us For Your Replacement Window And Replacement Door Needs.

ACM PRO Windows and Doors has been proudly providing residential door and window services to homeowners in Oshawa, Whitby, Bowmanville, Courtice, Ajax, and Newcastle since 1983. Our focus is on the private home owner and we do not do installation work or repair service on commercial, rental or income properties at this time.


We are the original Authorized North Star Window & Door Dealer in the Durham Region. ACM PRO is family owned and operated by Andy Illes, who oversees all sales and installations, ensuring continuity from start to finish and results and workmanship that you will be happy with. For peace of mind, we are an accredited BBB business, fully insured and WSIB compliant. 

Come in to see us today for your North Star vinyl window and patio doors, Dorplex steel and fiberglass entry doors, Aluminart storm doors, and Eclipse California Shutters, as well as screen repairs and installation of Wayne Dalton  garage doors.

We Service What We Sell

Repairs are a very small component of our business with little or almost no callbacks. For your peace of mind, we do “service what we sell,” and gladly stand behind our installations and the products that are purchased from us directly. We have easy access to our suppliers’ products and parts, which helps us keep repair costs down and response times to a minimum.


Getting An Estimate

Call us old fashioned. It may be in part what distinguishes us from our competition. We do not employ commissioned salespeople, and for that reason all inquiries start with a showroom visit. Making an appointment to see us is always a good idea as we do leave the showroom unattended. We also ask that you provide approximate measurements and indicate style and option choices on your visit to the showroom. Also, if you prefer "Full Frame Removal" or "Replacement/Retrofit Method," this will go a long way to expedite the quotation process. Please note that prior to any sales or installation services, we will always verify sizing and pricing accuracy with a "Home Visit". We do encourage prospective clients to visit our showroom, to see our products first hand.

ACM PRO Windows & Doors is an accredited business with the BBB. We are recognized with an A+ rating. Also a past "Business Of The Month" of the Oshawa Chamber of Commerce.
