REVIEWS

What Our Customers Are Saying About Us

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 storefront named Concept Windows & Doors. We went into that store because the front presented a neat look and an appealingly organized showroom. 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. The practical handholding has always been professional ahead of what one would expect in this trade. Franklin goes beyond the call of duty, always with a smile, a positive attitude, regardless of the outcome between the quote and the actual sale. Our first option when buying doors or windows, is to call Franklin. You won’t be disappointed.
