"... 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.

"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,...

"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. He was respectful of the cold winds outside and planned the installation to reduce any heat loss to a minimum. Wonder Windows price was substantially lower than the other bids...

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.

"... I am saving over $100 each month on energy bills!"

I just had to write you to tell you how pleased I am with my recent window project. I purchesed 5 windows from you in July 2011 that were installed in the fall. My house is so much warmer with my new windows and I am saving over $100 each month on my energy bills! I just can't believe the difference it has made in my home!

My husband loves the windows, in fact he won't close the fabric blinds or curtains because he enjoys looking through...

“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!

Niki B. Rochester, NY January 6, 2015

"I just knew he was good at his job."

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...

I was very pleased with everything. The process went as planned, the windows are awesome (glad I got them in before this weeks very cold weather), and the guys were very good.

Deb & Don L. Rochester, NY August 20, 2014

"... it is so good to be able to open all with the least amount of pressure... oh how I struggled to open, close or clean them..."

Thank you for the professional jobs that Bill & Bill did. We LOVE our new windows! It is so good to be able to open all with the least amount of pressure. I am expecting a total improvement in the furnace bills, I know we were losing so much heat through those old wooden windows that were put in when the house was built. Oh how...

Susan S. Williamson, NY December 2, 2014

Great work, very professional! Thank you!!

Katherine H. Rochester, NY April 2, 2015

Emily S. Rochester, NY July 9, 2014

Christopher S. Webster, NY May 20, 2013

Our experience was perfect. Gary was here when he said he would be. He went right to work, it's obvious he knows what he is doing, and finished slightly ahead of when he said he would. Gary is a very pleasant person and our windows are wonderful! Thanks so much.

Cheri C. Rochester, NY December 2, 2014

"Fair price + quality work= repeat business for this customer!!"

The whole thing was a pretty great experience for this first-time homeowner. There was no hard sell, and that's a big reason why I picked Wonder Windows (plus the good reviews and word of mouth). They gave me a fair quote for the windows and door installation. I was particularly happy with the work done on the door; I was replacing a broken down old storm door with a steel entry door, so he had...

Kevin & Debra M. Pittsford, NY March 6, 2015

"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...

Work was very professional & installers were very informative and answered all questions. Also, the installers were very efficient and cleanud up everything inside and out.

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.

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.

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.

“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.

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!
