Customer Reviews

James B. Kane

February 25, 2026 My wife and I joined several of our East Aurora neighbors recently choosing Paramount Windows to install all our new windows - Marvin Windows in our case - because they are well built, fitted, stained and installed at a great affordable price and with professional care. It was a pleasure to work with Clarke Doll and his kind, dutiful crew getting all our windows installed in just two work days! We love the quality protection and insulation the brand new Marvin Window provides - especially now! - Jim & Kathy Kane.

I couldn't be more pleased with the experience I had with this company and the quality of the product. Clark was very professional, informative, and helpful in my initial meeting with him and explained my options and the pros and cons of each. Unlike other companies I had received estimates from he came in with a fair price and he never hassled me for a decision and waited for me to get back to him which made the whole experience better for me. As for the crew, they were very respectful, clean, professional, and friendly. They came out in extremely cold weather and did a great job with the install and finished in a very timely manner and made sure everything was done to my satisfaction after the install was done. If you are looking for replacement windows, I would definitely recommend giving these guys a call, you won't be disappointed.

Everyone we dealt with was very nice and professional. Windows manufactured here in Buffalo! They banged out 14 windows in a day, came back the following day to finish 1 window and the flashing. Pricing was very much more reasonable than another company. Very high quality installation and window build. Would highly recommend Paramount!

Don’t look any further! Clark and his installers are professionals. Very respectful, they clean up after themselves and will accommodate schedules and requests. Window quality is excellent also. Extremely happy with the product.

Paramount windows will be my forever go-to window company. They did a phenomenal job on the 6 windows I needed to get replaced and a sliding glass door. Paramount windows has an excellent team that gets the job done. They were clean, respectful, and professional. Everything turned out amazing and was completed in a great timely matter. I would recommend this company to friends, family, and anyone who is seeking windows / exterior doors to be installed at their home!
