These windows are beautiful. We spent A LOT of time with Cliff selecting various types of windows- awnings, picture and fixed and slider doors of different sizes. Cliff is extremely well versed on his product and able to explain all the details. Customer support and dealing with minor issues- a small crack on the plastic on a side of a slider, one door not moving as easily, ensuring the screens didn't slide back and forth across a large span was above and beyond. Bonnie, Wayne and John were friendly and easy to work with. We are looking forward to the energy efficiency and beauty of these windows over many years.

When buying replacement windows, the most important factor is the quality of installation and service. QWD heard what I wanted, avoided high-pressure sales tactics, and then delivered what they promised, on the schedule they gave me. Their communication throughout the project was excellent.

Quick, courteous, and professional service! They found quick solutions to logistic issues around the house, and left the place as clean as they found it. Our home is over 100 years old and we could clearly feel a difference as soon as the installation was complete. We are loving the new windows and doors!

Mike Steckle was our salesperson, and he was straightforward and kept his hand on the job the whole way through including after completion. He is definitely the man to call for new windows. The install team did a fantastic job on a challenging replacement for a 200 year old house, and they were very polite and careful to keep our house clean. The new Infinity windows are so much quieter, and keep our house so much warmer it's amazing. It's hard to make an investment like this in replacing windows, but this certainly felt well worth it.
