Customer Testimonials

The sales guy, Dave Barton was great! Very informative on the entire process. The lead time from contract sign to install was almost 6 weeks (was told 6-8 weeks). The install team (the team that installed on Newport ave. in Buffalo - can't remember their names) were fantastic!! Our kitchen window was a bit troublesome (bad prior install) but the guys fixed the bad work and made the entire window look better than before! Clean and efficient...couldn't have asked for a better team! Great work!! Definitely would recommend!!


We had new windows installed yesterday. The entire process from Sales to install was great! The Sales Rep Michael F. was excellent! The install crew led by George was one of the best contractor experiences I've had. I couldn't be happier.


We have just had every window in our house replaced by Wonder Windows. I can't say enough about how quickly and efficiently they worked, and how clean they kept the work areas. I was expecting a lot more disruption of our lives as with any kind of construction, but the installers kept the disruption to a minimum. The windows look great and we can already feel a difference with the temperatures dropping at night. Would highly recommend!


My husband and I just purchased 9 Wonder Windows for our old farmhouse built in the late 1890s and which still had single-paned windows. They were a dream to install (says him, I was his cheerleader) and look fabulous! We noticed the warmth in the upstairs rooms (where they were installed) almost immediately! Not only do they keep the warmth in, they keep the cold and noise out! We are happy we bought our windows from Wonder Windows and look forward to purchasing the rest of what we need very soon!
