Wow! What a difference, Thanks!

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...

Sharon D. Rochester, NY September 16, 2013

The installers were very helpful and professional.

Matt G. Rochester, NY November 26, 2014

"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...

Daisy D. Rochester, NY September 19, 2013

"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...

Jim C. Pittsford, NY March 26, 2013

Very happy with my new garden window and replacement patio door. Great job on the installation, your staff was incredibly helpful, and cleanup was done properly according to my wife. Thanks again guys

Joan C. Rochester, NY November 20, 2014

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. I was very pleased with everything and would definitely refer folks to you, in fact my daughter and son-in-law are going to be calling to get a quote for springtime of 2015.

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,

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,...

George E. Hilton , NY December 8, 2014

I was very impressed with the installation. I was amazed to see how much the new windows have helped (no more draft or condensation on the windows).

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.

Dennis S Rochester , NY August 6, 2013

The guys did a great job.

Heather B. Rochester, NY October 27, 2014

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

Jesse & Susan H. Rochester, NY August 5, 2013

Excellent job. Mike & Joe were a Godsend. They can work at my house anytime.

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.

Joe & Lucy N. Rochester , NY January 16, 2015

Carmen was punctual and considerate. He was also efficient, tidy, and vacuumed after he finished. It looks good to me, both inside and outside. I would recommend Carmen for other projects.

George H. Rochester, NY June 12, 2012

Crew was very thorough and polite. I apprecciated them cleaning up afterwards.

Niki B. Rochester, NY October 9, 2014

I am so pleased with my new windows. They not only look beautiful but we noticed that the traffic noise is almost non existent. Our installers father and son Bill and Bill were amazing! Very professional and efficient. They took care of my furniture and belongings by keeping them clean and safe. I have already recommended you to friends and family and plan on using...

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.

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...

William S. Rochester, NY February 2, 2011

“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.

Enzio R. Rochester, NY December 14, 2012

Nice job! Thank you!

Yarisa A. Rochester, NY April 5, 2013

Very nice job-thanks!

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!

Christine S. Fairport , NY December 15, 2014

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.

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...

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.

Jason And Sam L. Mendon, NY October 9, 2013

Friendly service. Great looking windows.

Michele M. Williamsville , NY July 23, 2014

I love my windows they are beautiful. Thank you very much. I have another bedroom with 6 windows that I can't wait to have your company install in the future!

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.

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...

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.

William B. Rochester, NY August 20, 2014

An overall good experience and we are pleased so far. We will be quoting work to complete the front half of the house next year and we will definitely be calling Wonder Windows again!

Great experience- installers were professional.

“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!

Suzanne S. Webster , NY September 13, 2013

Great work, clean & fast. Thank you!

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!

Five minutes after Carmen was out of my driveway after expertly installing my new kitchen window I called Mark Lazeroff and left a glowing voice mail message on his machine expounding on how pleased I was in every way with dealing with your company, from the first meeting with Dave Barton to the extreme professionalism and friendly courtesy from Carmen your installer. Wonder Windows did a superb job and I will certainly recommend you to others.

Chase is a very knowledgeable of your product. He does excellent work. I would recommend him anytime. Great job!

Dave And Jeannine Y. Rochester, NY July 3, 2012

I just wanted to let you know what a wonderful job the men did today installing the block windows in our basement. They were very nice and so neat cleaning up after themselves. I was truly impressed! We should have had the windows done so much sooner. They look so nice from in and outside. I will highly recommend you to our friends. Thank you!

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!

Denise B. Rochester, NY May 16, 2013

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

Great workers!

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...

Tony & Lisa T. Rochester, NY May 21, 2013

Good work & good job.

Joanna M. Webster , NY January 22, 2015

Charlie is amazing to deal with. Wonderful at what he does!

Rosemary P. Rochester, NY April 9, 2012

I wanted to say thank you to all involved in the process of our new window. I had concerns because the window is very large and very visible... you helped us puck out the best window for our needs. The install team came over and basically whistled while they worked. They were great... neat, fast, cleaned up and kept me informed.

Dale M. W. Henrietta, NY May 14, 2013

Great job! Kept at work until done.

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!

Michael & Cindy L. Penfield , NY January 31, 2015

We are ecstatic about the fantastic install job. The quality is superb and the installation is better than superb. The best of the best. Very happy customer!

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...

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.

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

Annita K. Buffalo, NY December 3, 2014

"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...

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...

Robert T. Palmyra , NY January 21, 2015

We were extremely pleased with the installation of our windows. The crew did a great job and were also polite and friendly. We have already contracted with Wonder Windows to install an entry door and will not hesitate to recommend Wonder Windows to others!
