Customer's reviews

I ordered a custom door through Delco and their crew installed it. I did the full brick to brick installation. I ordered a custom colour and the match was perfect. My new door looks fabulous. I am very particular and I must say the sales staff put up with me. Lol. My only caution is the installers are very good, but they’re only concerned about getting the door installed correctly. If you have custom door accessories like a ring doorbell or a security system be prepared to install it yourself, or have someone else lined up to reinstall them. Finally, just a word about custom trim. If your replacing a legacy door (brick to brick) in all likelihood the trim will get damaged during the installation. So be prepared to have the trim replaced or have someone in to repair and paint it. ~ Ron v
It's been about three months since we've had our door installed by Delco and we are very pleased with how great it looks and functions. It's a nice solid thump when it closes. :) Everyone that has come by has always commented on how beautiful it looks as well. This was a brick to brick install and the installation guys were great and the outside is perfect with how well they blended everything. Delco was also very accommodating in the beginning when they were helping us pick out the door and meeting with us off hours due to our busy work schedules. The only downside was that our door was delayed by two months due to the manufacturer messing up but was not the fault of Delco and they did help us out a bit to compensate us for our troubles. Will definitely look to them again in the future if we need new doors or windows. ~ Jose R
I purchased a front door and a window from Delco. I chose them based on their positive reviews, so it’s only fair that I reiterate how great this company is to work with. Not only are their products great, very sold and high quality, but I was so pleased with the customer service. Everything was exactly on time and communication was great. As I was travelling a lot, they accommodated my change of installation dates twice without hesitation. Further, my window screen was a little too tight to remove and replace easily which I only noticed a few weeks after installation. They quickly came back and replaced the screen. So their customer care continues after all payments have been made, which is appreciated. I highly recommend Delco Windows & Door. ~ Jane G
