"The OKNA brand was one of the few with highly positive quality reviews and Wonder Windows had equally positive consumer evaluations!"

I was very pleased with every aspect of my experience with your company. Replacement windows being a fairly expensive proposition, I did considerable research into not only window brands, but reseller/installers. The OKNA brand was one of the few with highly positive quality reviews and Wonder Windows had equally positive consumer...

"The prices are fantastic..."

Fantastic experience, great windows. This is the third house where I've replaced windows with Wonder Windows, and every time we've been happy. The rooms with these windows are warmer, and they have improved the look of our house inside and out. The staff was knowledgeable and on time. Their work was quick, clean and on schedule. The prices are fantastic- it wouldn't be that much cheaper to install windows by myself, and...

"Wonder Windows price was substantially lower than the other bids and caused me some initial concern. After install... no change in price and I was extremely satisfied.!"

Wonder Windows installed 22 windows and one sliding glass door. The installer was professional and highly knowledgeable.

"...Everything was perfect inside and out."

They were on time. The quoted me 3 days to do all my windows but it only took a day and a half. The crew was great, made sure everything was perfect inside and out.

We are very pleased with our window installation. George did a wonderful, meticulous job. His assistant did also. We definitely would recommend Wonder Windows.

Loretta W Scottsville, NY October 4, 2013

The installation went very smoothly. The installer JR was on time, courteous, personable & treated our home with respect. The floors & the counters surrounding the windows were tarped-off to minimize dust. I really appreciated that because I expected to do a good amount of clean-up, but I was pleasantly surprised! The windows looked great & we look forward to having the remainder of the windows replaced by Wonder Windows.

Mary Cay L. Rochester, NY July 25, 2012

I just want to say thank you for the installation. Carmen was an expert at what he was doing! The actual install went so smoothly that it was all said and done in 2 hours. Down the road, we'll certainly be back to purchase more windows. Can't do a lot at one time, but we will definitely call you when it is good for us.

David & Aretha F. Rochester, NY October 1, 2014

“Windows and insulation…like a down comforter over our house!”

This is simply a follow up note to thank you and the entire team for the professional job performed to “button up” our home against the wintry blasts just ahead with windows and insulation. It’s like a down comforter has been thrown over our house with promises of fuel savings to boot!

Tom B. Rochester, NY November 2, 2012

Gary H. Rochester, NY August 28, 2014

I wanted to let you know that Gary W. did a phenomenal job and he is the real deal. I am extremely happy and would recommend Wonder Windows. I am an experienced carpenter and it is difficult to impress me; but Gary did! If I ever need more glass block windows you will be my first choice.

Great job! Windows fit perfectly & installers were friendly and professional.

Sheila C. Rochester, NY June 19, 2015

"I had 2 other quotes and he was the lowest..."

The windows looks better than I imagined... Right from the start my salesman (Eric) did a wonderful job of explaining my options, he actually had a window to show me. I had 2 other quotes and he was the lowest, even with taking the flower boxes away and adding my siding. The installers were great. First thing after "Hello" was "You're going to love your windows." Nice. They were pleasant, did...

Scott M. Webster, NY June 12, 2015

I definitely will call you guys again when I replace all of my doors.

The windows are fantastic. Once installed, we started noticing a small draft down our chimney. Air takes the path of least resistance into a negatively pressured home. Apparently our old windows let in more air when CLOSED than out fireplace/chimney! I definitely will call you guys again when I replace all of my doors. The workers were fats and courteous, and the prices were very competitive. I'm glad...

Frenchie G. Rochester, NY August 29, 2013

Great job and on time.

"We are so grateful to everyone at Wonder Windows for making this experience so posititve..."

We are incredibly happy with all of our new windows and doors! Toby LOVES his pet door and we love that we don't have to get up every time he needs (or wants) to go out. Dave was very professional and helpful during the sales process. The installers were very professional and did a fabulous job installing everything; replacing all of our windows and most of our doors...

Bob & Donna B. Rochester, NY March 24, 2014


"They were professional, clean, friendly, efficient, I can't say enough good things about our experience with them"

This past March you sent a crew of Mike, Al, and Steve to install almost 20 windows in our Irondequoit home. On the fist day almost all the windows were installed (amazed ME at the speed!), and the next two days they finished the install and trim work.

In a word the guys ROCKED it! They were professional, clean, friendly, efficient,...

Laura R. Rochester, NY December 11, 2014

"We are extremely happy with the windows and the company as well. The windows are doing their job. No more "draftiness" or "walking into a cold room". Please accept our congratulations for your wonderful products and impeccable services!"

We are writing to your company, "Wonder Windows" to express our great pleasure and gratitude to you for your marvelous product and service.

William W. Shortsville, NY August 17, 2015

These guys are the best! What a great job and attention to detail!

Robert T. Palmyra , NY January 21, 2015

Great job!

Christopher S. Webster, NY May 20, 2013

Melvin C. Rochester, NY February 5, 2013

Excellent job- the best by far!

Tom C. Rochester, NY June 26, 2014

First of all, Bill and Bill did a great job installing my windows this week. There were professional, hard working, organized and very clean. They are very good at what they do and are a credit to your company! Thank you for all your effort, hard work, cooperation, and patience when I was deciding which company would do our windows! It appears that with your help, we made the right decision.

Jessica E. Rochester, NY August 11, 2014

"...We will definitely recommend Wonder Windows, and use you again! You have some top quality employees!..."

We had an absolutely wonderful experience with both the installation and repair of our windows and door. Bruce and his team did a professional job that even stood up to my husband's quality standards. (My husband has never been happy with any contractors work!). He came home and said, "nice job, wow, really nice job". We were so disappointed...

Denise B. Rochester, NY May 16, 2013

I am very happy and pleased with my windows, the installers were professional.

Elissa H. Rochester, NY June 19, 2015

Wonderful job.

Christine S. Fairport , NY December 15, 2014

"The installers were very kind and professional..."

It definitely feels warmer in the upstairs. We are looking at replacing the lower level now and would like another estimate for the remaining windows. We are very excited about being able to open the windows come springtime. The installers were very kind and professional and answered all my annoying questions.

Annita K. Buffalo, NY December 3, 2014

Everything went better than we had anticipated. Please, please tell the crew (Keith and his installers) that they did an amazing job! We love them!!

Emily S. Rochester, NY July 9, 2014

Thank you again for your explanation and prompt response. The reason I decided to go with Wonder Windows is that they gave me the best quality window for the price. Your answer makes me even more confident that I made the right decision. I look forward to working with you again!
