Wonder Windows Reviews 2026

Explore Wonder Windows reviews on this Rochester and Buffalo based installation company. Wonder has been in business since 1963 and specializes in installing replacement windows, as well as entry doors and patio doors.

Are Wonder Windows Any Good: The company uses several brands of windows, including Okna, which is a very well regarded brand as far as I'm concerned. The two other brands they rep are Sierra Pacific and Oknoplast, which I have heard of, but know very little about. Sierra Pacific Windows Reviews

Oknoplast is a European window brand that is looking to break into the U.S. market - I've now seen a few companies in the U.S. that sell Oknoplast - all on the east coast. Oknoplast makes both vinyl vs aluminum windows. The brand looks to be promising, which is exciting, but I'm going to reserve judgement until I know more.

Overall Rating: Wonder Windows get a 4.6 out of 5 stars based on 2 consumer reviews below.

Wonder Windows Reviews

Wonder replaced our 20 plus double hung windows maybe 5 years ago. I promised I would let you know how they turned out and I am just getting around to it now. How time flys! In a word, they were great from start to finish. We bought the Okna 1800 triple pane option and they have been perfect (I should say we haven't had an issues once they were put it). Like I mentioned, our house backs up to a busy street and the windows have help tremendously with the noise, which is pretty constant.

I would say it was a worthwhile investment to be sure.

If I'm being nit picky, I felt like the windows were not cheap (I want to say we paid $1130 a piece, but it was triple pane). The other little thing was they one mis-measured one of the windows on the side and that had to be reordered and installed at a later date. They were prompt about following up though and took care of a couple questions and adjustments we wanted. All in all a very good experience.
