Testimonials
As developers of luxury single family homes, we have used during the last ten years many window and door suppliers. About two years ago, we saw a new store front named " Concept Windows & Doors " on Sepulveda Boulevard, practically across Costco. We went into that store because the front presented a neat look and an appealingly organized show room. There I met Franklin Castell. His presentation of the enterprise was professional and concrete, highlighted by a history of his experience in the field. Since then we have concluded important purchases at very competitive prices. His service has been outstanding, before and after the sale, with many calls in between to inquire the outcome of the installation, the product or future needs.
Dear Concept Windows & Doors. I want to thank you the excellent job you did in helping me select the ideal windows & door for my properties. Not only were price great but your service care and attention to detail is superb. It amazed me that despite the hundreds of items I ordered from you, from complicated windows to intricate doors to molding to hardware, everything was delivered on time and as ordered. I will recommend you to all my colleagues friends & family. Count me as a very happy customer.
Hello, my name is Ron Eisenberg and I own the Quintessence of Art Co. since 1980. Over 30 years ago I had the very good fortune to have met Mr Franklin Castell and found him extremely knowledgeable on all my door and window requirements. Whenever, I needed a product or had a very difficult door or window problem Franklin was always there for me with the answers. He is my problem solver! Over the years we have become friends and I know if there was ever a person to answer or find a product for me, he is the man. I have always received prompt service and if a problem should occur on finding me a product or answer he will always follow up with me and keep me informed on its progress. All I can say Franklin knows his stuff. Thank you Franklin for always being there for me and my company.
In my opinion, doors and windows are one of the most important aspects of any building project. Besides setting the feel for the house or building, they are one of the most expensive and complicated products to order. Every opening is different and to execute a project correctly, all those details have to be thought of. The main reason I use Franklin at Concept Door and Window because of his knowledge and attention to details. The second reason I use him is because he has the best prices. I would recommend Concept Door and Window to anyone interested in getting the job done right.
