"My name is Jason Haslbeck and I live in Chester County, PA. My wife and I have used Castle Windows for the replacement of all our windows, a new front door and now a new custom French Door slider (three separate project installations). Our sales representative, Roberto Munoz, has been an absolute pleasure to work with for all of our installations. Their customer service is excellent and their products are the best in the industry. Their lifetime warranty is legitimate and very valuable. Due to the Corona Virus, our latest project design consultation (French Doors) was done over the telephone using a ZOOM application. Very convenient technology and the presentation was very professional. On a personal note, our sales representative (Roberto) is a very faith based, honest human being and we have never been happier with a contractor or sales representative. I would highly recommend asking for Roberto Munoz as your sales representative as he is very knowledgeable, professional and courteous. Overall, from my experiences, Castle Windows is the best window and door company in the region. We did extensive research in comparing them to Pella, Anderson and other companies and Castle's product quality, installation and pricing was the best value by far. I would normally never take time out of my day to write a review, but my experience with Castle Windows (and Roberto Munoz) is one that deserves recognition.
