"The windows were pricy but the quality of the windows justifies the price. The crew that installed the windows were wonderful to deal with. They cleaned up after themselves. The project manager was very understanding when I needed to change the schedule due to weather. They accommodated to my schedule changes for installation. They were very professional"

"What a great company to work with - from Sales to install it was seemless. Peter was thorough and communicated with me every step of the way, The 2 guys (Joe & Bill) who installed my Anderson patio door were so clean and neat - they did an outstanding job and I just love my new door. I replaced French doors with this slider as it is more practical. I have been looking for someone to do this project for about 1 year. Anybody that came to give me an estimate never got back to me - it was really unbelievable!!!!!! I highly highly recommend All Island Window & Siding. I promise you this will be the best decision you make."
