We have used Wonder Windows to replace all of our windows and have had great experiences. The windows are top-notch quality. From selecting the windows with Tom Garman, having the window space carefully measured by Steve Klaver, and working with Bill Cue to install the windows, the experience has been phenomenal. A great team with a wonderful product.
They did a great job, Steve Klaver was on time and he explained everything in detail
Windows are very nice, competitively priced, and installed efficiently with care. Austin and Austin are great installers- thoughtful, pretty quick and polite.
We had an issue with a window that would not close and lock properly. Steve from Batavia came out and fixed it extremely quickly. Very courteous was not upset because he had to be here. Just did a great job very personable. It’s nice to know if I have another issue there will be someone that will take care of that promptly for me
