Get matched with top window pros in Niagara Falls, NY

"We had an excellent experience with Wonder Windows. The young man who replaced 28 windows in our double house (Brian) was punctual, efficient, friendly and polite. We were amazed at how quickly his excellent work was done."

"I am extremely impressed with the quality of the windows and how knowledgeable our salesman Joe was. I previously had such drafty old windows, my only regret is that I didn't do this sooner!"

"The installers came on time and were totally professional, experienced and worked continuously until the job was done. The triple pane windows are fabulous because compared to our old two pane faulty windows, not only are they solid and beautiful with no wind blowing through, but also the nearby road noise is greatly reduced. We needed to use plastic film to insulate the old windows and when the wind blew the plastic would billow like sails! The new windows make our condo seem like a true home."

"The window covering came out very good."

"Fast and great service and work"

"Quick and efficient, hadn't really cleaned my porch in years and got tired of the excess build up and filth, professional and exceeding what I was expecting."

"Professional, attentive, thorough and friendly from start to finish. Installation crew was absolutely amazing! I had all windows in house replaced and it was was done much faster than I imagined. The crew was friendly, knowledgeable, efficient, and cleaned up everything each day. I love the new windows! Highly recommend!"

"Excellent workmanship and communications. Ours was a relatively small job for them ($700). But, in a way, I believe a small job says something important about a business that often does jobs that cost thousands of dollars. The office communications in setting up the job were very responsive. The two craftsmen that worked on the job were communicative in what they were doing, and worked in a very professional manner. After completion of the work there was a little mix-up in processing the invoice; however, that was resolved with integrity by the office and field representative working together. I would contract with Graves Brothers again; in fact have scheduled another project for them to replace two attic windows and install a large fan in one of the attic windows."

"Hired Vin to install a sliding door to replace a window in my office. He and his crew did an excellent job and went above and beyond to make sure everything went perfectly. I canâ t wait to see what they do on my next project of adding a deck in the backyard. I highly recommend."

"Excellent service, quality materials, professional, fast, clean. The best choice of 3 options. Very satisfied with the entire experience of full tear off of cedar plus two layers of asphalt shingles and replacement of 3 skylight windows."
