I just wanted to write a quick review to especially highlight the amazing customer service I received from Preston. Sometimes when a large purchase is made, the customer service ends after the sale is made. This is NOT the case with Island Windows and Doors. I have called twice after installation with various questions and Preston not only responds to my emails quickly, but he even comes out to the house to take a look to make sure everything is working perfectly. He is friendly, kind, knowledgable, and professional. I am the kind of person who usually asks a lot of questions but he is patient every time. I can’t say enough about the excellent customer service that continues even after the sale is made!
