“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 M. East Rochester, NY April 21, 2009

“actually had to lower my heat”

I love my windows! I actually had to lower my heat the first night because the house was so hot!!! It’s amazing how my old windows lost so much heat!

Great job, thank you!

“a firm that meets its commitments”

Recently we contracted with your firm to install replacement windows and have our garage vinyl sided. I can’t tell you how much we appreciate actually dealing with a firm that meets its commitment dates. In addition to an efficient installation, your men cleaned up the area quickly and completely.

The guys that did the installation were just great, clean, friendly and fast. It was nice to have people who really know what they're doing. I have had experience with just the opposite before, the windows are great and look amazing as well thank you so much.

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.

Kathleen W. Rochester , NY September 27, 2013

Great installers.

Gerry T. Rochester, NY July 22, 2014

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 was a very big project and they worked hard to complete it in a timely fashion. We are so grateful to everyone at Wonder Windows for making this experience so posititve and...

“I would recommend your company to anyone”

Thanks so much for installing the twelve windows in my Rochester home.They are lovely & the house is so warm & snug & also quiet – the old windows were horrid.

I want to tell you about the two men who did the installation. I don’t know their names but they were both so efficient in working together putting each window in. They were friendly and very careful coming in and out. They even helped...

Dale A. Rochester, NY June 30, 2014

"... you worked with us to give us the best price and best window possible..."

My experience with Wonder Windows was one of the best I have ever had with a contractor and sales person, you truly hold to standards. When coming to service and install you worked with us to give us the best price and best window possible. The installation crew that you sent were very professional and respectful of my house.

My windows have been in for two weeks I have already...

Sarah B. Hilton, NY December 19, 2013

"Your customer service is at the top along with your product."

I am truly a satisfied customer and will continue to support your business. Your customer service is at the top along with your product. Being an employee of 24 years with Wingman's, both are always extremely noticed.

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.

Darryal J. Rochester, NY September 9, 2013

Great job, nice guys. Very professional.

Mike L. Pittsford, NY December 7, 2012

"I should have done this years ago."

We are very pleased with the installation. Already noticed a difference in how warm it is in the bathroom with them installed. I should have done this years ago. My wife and I were also discussing a bay window to replace the old window in our dining room. I will give Wonder Windows a call to get an estimate.

Andrew S. Henrietta, NY August 15, 2013

The installers did a awesome job. Very professional and highly skilled. Thank you!!

Katherine H. Rochester, NY November 21, 2013

"Thank goodness I found Wonder Windows!"

After having some distressing construction experiences in the past and not knowing where to turn or how to proceed, thank goodness I found Wonder Windows! My property is finally starting to come together and becoming the place I want it to be. Thanks to your teams of Bill Sr. & Jr, and master craftsmen George and Renee, who all did professional jobs & are excellent. But a "special' thank you to Dave, who...

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.

Cathy H Rochester, NY January 5, 2015

Excellent job and very professional. Will recommend Wonder Windows to others, thank you!

Louise D. Rochester, NY January 12, 2015

Blaze is a terrific installer. He did an excellent job. I am very satisfied and would use Wonder Windows again and tell others about the company!

Sandy & Rex C. Lake View , NY August 28, 2014

Windows look beautiful. Blaze is very knowledgeable and hardworking. All concerns were addressed immediately and professionally. JR also worked very diligently and was very respectful. Would also like to mention that Dave Barton (our sales rep.), Sarah, Jan and Rebecca all represent Wonder Windows in a very professional and prompt manner. Everyone was very kind and addressed all questions within minutes. Quite impressed with your staff!

Mike A. Chili, NY March 4, 2013

Very efficient and always courteous

We are very pleased with our new windows and wish to thank you and all your people, especially the two gentlemen…. who actually installed the windows. These two gentlemen were just that, very efficient and always courteous — we felt that they were friends. Thank you again,

"...the type of window that we selected which is truely a wonder!"

I would like to compliment Wonder Windows with the final result of our installed windows. My husband and I are extremely satisfied with our new windows; not only with the professional workmanship that we witnessed but the type of window that we selected which is truely a wonder!

Great job, very nice, extremely quick and clean!

Mary Cay L. Rochester, NY April 19, 2013

"...worked with us to make the cost fit our budget withoug having to go to financing."

One year ago I purchased two double hung windows from Wonder Windows. At the time that was all I could afford but I wasn't about to sever ties with them. This year we decided to get estimates to install a few windows at a time. Well as we discussed this possibility, the salesperson worked with us to make the cost fit our budget without having to go to financing. The installation...

Michelle M. Rochester, July 11, 2013

Thank you!!!

Daisy D. Rochester, NY September 19, 2013

Very pleasant, efficient and on time!

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,...

Tracy B. Penfield , NY March 13, 2013

Thank you for suggesting the window in my dining room- what a change it has made! Totally awesome! I am so happy with the service and can't wait to get more windows and doors... the big picture window is next! I also want to say that the 2 installers were awesome- they saw my 93 year old neighbor crash into her garage and went to help her- so kind! Thank you!

Pat H. Greece, NY August 12, 2011

Outstanding workmanship

I am extremely pleased with my window purchase from you. The installer was very accommodating and did an outstanding installation job. The workmanship was outstanding, as well. I was a little apprehensive, being a single home owner and being a female, but was pleasantly surprised as your service was with me in mind.

Matt G. Rochester, NY February 9, 2015

"The new OKNA's, warm as can be, no draft etc..."

We are very pleased with the product and your company. It's amazing, I stand next to one of the remaining original windows and feel the cold coming through like a waterfall. The new OKNA's, warm as can be, no draft etc... Thanks again, and you certainly have my recommendation!

Carol And John E. Rochester, NY August 23, 2013

Great job. Nice guys.

Andrew R. Rochester, NY July 30, 2014

Installers were wonderful! A great experience.

Victoria S. Pittsford, NY November 14, 2014

Beautiful job!  My windows required some extra skills and Wonder Windows crew delivered 100%.  They were knowledgeable and considerate of their surroundings.  I would recommend this compay without hesitation.

I have had much construction done to this house and the windows were the easiest!!

Thank you for a great experience

Ed C. Rochester, NY January 24, 2014

"You have a quality product at a fair and reasonable price...Wonder Windows takes the pain out of buying windows!"

I would like to take this opportunity to thank the installers that worked installing my new windows. They were very professional and went out of their way to make sure I was fully satisfied. Your company will get many referrals from me to use you. You have a quality product at a fair and reasonable price. My installers were a father...

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...

Jessica B. Walworth , NY January 9, 2015

George and Rene were very hard-working and professional. We love the windows and appreciate their extra work.

The windows are beautiful and work extremely well! The guys were great to. Thanks so much.

Lunzer E. Rochester, NY November 1, 2014

Your workers were very clean & tidy. We were concerned about lead here, but they wiped down and vacuumed up everything. I am very happy and so are my tenants.

Jim C. Rochester, NY October 14, 2013

Very nice product and the installers were very professional.

Diane G. Rochester, NY October 16, 2014

James R. Rochester, NY November 1, 2013

"You cannot beat Mark's prices and I am 100% satisfied."

After much research, I decided on OKNA replacement windows which were offered by Wonder Windows. The windows arrived in about 4 weeks and were installed 2 weeks later. The installers were on time and very professional and friendyly. They protected my floors and carpets. The install took about 4 hours and they cleaned up every speck of debris. The windows not only look great, but provide a noticeable difference...

Karl & Shirley J. Hilton, NY July 26, 2013

Great installers- did a wonderful job.

Zicari E. Rochester, NY July 30, 2013

The installers did a great job!

Rob & Rhonda M. Pittsford, NY January 19, 2015

"After only a few days we noticed our house was warmer and much quieter overall."

Just wanted to let everyone at Wonder Windows know that both Rhonda and I are thrilled with our new windows. After only a few days we noticed our house was warmer and much quieter overall. The crew that came to our home was wonderful. Both Mike and Al were professional and came to get the job done. They worked quickly and efficiently under some very trying weather conditions with...

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!!

Darlene W. Rochester, NY September 12, 2013

Very pleased with the window installation. Excellent and clean work crew.

Phenomenal and very very professional!!

Geral S. Palmyra, NY July 22, 2014

"...your office communicated with us every step of the way..."

We couldn't be happier with our new windows! From start to finish it was a great experience. Our introduction to Wonder, Eric, was so helpful and so patient with our questions. He recommended an awning window for our kitchen and he was absolutely right... I enjoy just standing in front of it and admiring our yard! Your office communicated with us every step of the way. The installers were wonderful...

LaRee M. Rochester, NY February 6, 2013

We had a wonderful experience with Wonder Windows and have already started to refer our friends to you. We will definitely come to you first next time around. :)

Heather B. Rochester, NY October 27, 2014

The two gentlemen were very good (excellant) at the job and clean up.

The experience was good. Eric was personable and seemed knowledgeable. Did not take significantly longer than I had expected and was able to answer my questions.

Fast, courteous and good sense of humor.

Tom S. Fairport, NY September 25, 2013

Great job!

Laura W. Rochester, NY September 13, 2013

They are fantastic. You can buy the windows yourself and install. If you want them to install, they will come by and do a free estimate. Eric does most (if not all) of these and is professional, prompt and firendly. There are options to keep things more affordable.

Tom B. Rochester, NY November 2, 2012

"Glad we called you and only you."

I was VERY pleased with Dave and his laid back soft sell no pressure approach. You've got a good man there as Sales Manager. Glad we called you and only you.

Enzio R. Rochester, NY December 14, 2012

Nice job! Thank you!

Niki B. Rochester, NY January 6, 2015

I've already noticed a slight change in the warmth of my living room. I can't wait until summer to open the windows and get in fresh air and cross winds. The refund was great and I am so appreciative to the company for pointing out that I didn't need the trim wraps in the front! By the way, the workman worked hard, acted professional, was good with my dog, and he obviously knew what he was doing. After watching him a short time, I just knew he was good at his job. Many many many thanks!
