(Found on CheckBook.org) I chose Crystal Exteriors because of the attention to detail and product knowledge shown by its owner, Mr Edgar Li, when he provided an estimate. He was very responsive and helpful as we worked to get the right doors for our house. Once we decided on the doors, he kept us updated on their construction and delivery. His installation crew was extremely professional, hard working, did an excellent job keeping construction debris out of our house, and a superior job site clean-up. Mr Li is without a doubt the most competent and trustworthy home improvement contractor I’ve ever hired.
