There isn't enough room to detail all the problems we've had with Champion to replace all of our windows as well as our front glass door. They installed our door incorrectly TWICE. Despite coming out twice to measure our windows, they ordered the windows in incorrect sizes and initially said they couldn't install them. Somehow, they did, but we're unsure exactly how or what damage was done to make them fit. The wrong fogged window was ordered. Screens weren't provided for several windows. Our salesperson, Mason Brennan, sold us on being the only point of contact we'd need, but then ghosted us when we began experiencing problems. Overall, absolutely terrible experience. We paid tens of thousands of dollars and received abysmal service. We've warned at least a dozen neighbors, family members, and friends to avoid Champion at all costs.

Quality windows! Quality service! Exceptional professionalism!

Hassling me for the final payment when we are awaiting two windows

Every thing was a great experiance from sales to install.

Terrible customer service. Constant pressure to sign Certificate of Completion even though work was never - to this day - completed. Multiple handles on the casement windows have fallen off. I have no children at home. The windows are not abused or mishandled- it’s an overall poor product and poor product design.

Took too long 4 months to install. The storm door was the wrong size and I don’t know when that will be completed. The crew who came were very rude and combative upon their arrival. They were very loud and they yell

Champion windows came highly recommended by our neighbors. The windows and patio door have now been installed and are definitely NOT what we had expected. I have already shared an email with your CI-Team on Wednesday 6/11/25 (two days after installation) with a list of things that are not satisfactory, and have not heard back. They DID communicate regarding the fact that a repair order had gone in regarding a window (master bedroom) that arrived here with a broken pane, and the lock cylinder in the sliding door is faulty. We have not yet received any response to our email - not even an acknowledgement that it has been received.

Quality of product and installation

Still have not received $400 credit card that Matthew Slavin said was approved over a month ago.

Windows look great & installers were awesome

Super pro team of installers

Communicative and professional through and through!

The service of your employees the pride and quality of their work. The windows are great a quality product I am so happy to have them no noise, no dust , and best of they control the temperature to a comfortable environment.

Great work

Champion windows may be good products, but the company lacks in customer service and customer support.

Two installers worked hard for 6 hours. They were exceptional. All done except screen door had a rip and the bottom stops were cut too short. I have to wait 2 weeks for screen door then a 4 hour window which is ridiculous since if you had done your work correctly I would not be in a position to waste 4 hours

It’s really to early I feel to rate Champion. The up front installation went very well well, but as a new customer let’s see how you respond when a problem occurs.

One of the windows broke after installation same day

Follow up very slow

The team was extremely professional, and I’m continually impressed by the quality of the build.

Salesman did not emphasize how GREEN the tint on these windows are. Also did not emphasize that since all UV is blocked, any plants you have will die. I am not happy with the product but realize I am stuck. The windows themselves seem to be an OK product. They are also EXTREMELY expensive.

Efficient, quick, good quality

Staff are very helpful, install was great. Great product.

Started process in Jan 2024, finally completed in April 2025

Order was lost multiple times, communication was poor (I had to repeatedly initiate most and responses were not consistent)
