So far we have had over 10 windows replaced and 6 more coming up. We also had a faulty top sash that needed replaced. All happened without any issues or concerned. Very simple process working with window world and have had a great experience so far! Planning for more windows in 2027.

Be careful how your contract with finance company is set up—not as clear as the salesperson makes it sound. Be sure to check the duration of the interest-free financing agreement.

Very pleased with our new windows! We had 9 windows replaced, two doors and a full bay window and are so happy with the work. The guys were very thorough and SO fast. Everything was done and cleaned up in 1 day. The price was extremely fair and we are over the moon with our new windows for the fall!

We’ve had Window World windows for about 15 years and we absolutely love them. We’ve had three small issues and they always come out the same day and with this and with a lifetime warranty you can’t beat it. Thank you so much Window World.

Window World installed our windows & sliding door 3 years ago, and we have been very happy. Today, Adam came out as we needed an adjustment. The fix was quick and easy, and Adam was fantastic. I will absolutely buy from this company in the future due to great products, great service, and great people. They are clearly very well managed.
