“I’d like to take this opportunity to express my complete satisfaction with a recent job you completed at my home of installing windows, patio door and siding to the front of the house. Your crew was polite, efficient and professional while working in extremely cold weather. I’d also like to commend your Design Consultant, Harold Hyer, on his professionalism in working on the estimate for this job. He took a great deal of time to make sure I was satisfied with the work to be done. Rest assured I will be recommending your company to friends who are interested in your products.”

“I am writing this letter to let you know how pleased my wife and I are in choosing Window World to replace the existing windows in our home. Your salesman Matt was wonderful and very professional. At no time did we feel pressured into purchasing the windows. The windows arrived on schedule and were installed by two very nice gentlemen. They did a fabulous job and were very neat. We had one issue with the kitchen window and your service man Jonathan was at our home the very next day. A new sash was ordered and Jonathan was here in a very short period of time to do the install. Once again, we are very happy and would definitely recommend Window World to anyone who might be interested in replacing their windows. Thank you.”

“I am sending this note which is overdue. I was and am very happy with the installation of the windows I bought from your company. Your installers were very professional and polite. It was a pleasant experience dealing with them that day. I am also very happy with the windows that they put in as they make the room look brighter and bigger than before. The extra touch of the caulking that they did made it a much better looking job than I had envisioned. I want to thank you and your people that I dealt with; the lady in the office that I talked to a couple of times on the phone was very pleasant and Jim Siolos who came to the house and sold the windows to me. Jim was also very professional and polite, and was not a high pressure salesman, which I really appreciate dealing with. And last but not least, your installers (a big guy, I think his name was Ted) and his partner (a smaller gentleman) did excellent work and gave me a very beautiful finished product. The whole deal from start to finish was a very pleasant experience. Money well spent. I certainly will recommend your company to anyone I know or who is interested in any of your products. Thanks very much.”
– William T.

“Your installer recently came to install 5 replacement windows in my house. He did an excellent job, as he was efficient and cleaned up all the debris. Everything went very smoothly as he was on time and did not stop until the job was finished. Your energy efficient windows are of a very high quality. Also you were more economical and offered more choices than most stores. It’s nice to see a business that delivers what is promised.”
– Barbara S.

“My condo finally inspected and approved the patio sliding replacement door your company installed on Feb. 14. They are satisfied with the quality and the appearance of the door. I also would like to take this opportunity to inform you that it was a pleasure to do business with your company. Everybody I dealt with was very helpful and answered my questions clearly. I would like to thank the salesman, the installers and the staff in your office for the ultimate customer care experience. I believe your company will have a successful business in Long Island.”
