Edgar Li helped me select a quality entry door for our home. I had difficulty deciding on the appropriate color and design. He provided me with numerous pictorial samples and quotes and recommended that I get two sidelights to brighten my small front foyer. He was correct. With the extra lights entering the foyer, it now looks twice as big, yet the privacy is still there. Edgar Li was patience and professional from start to finish. I would gladly recommend Crystal Exteriors to friends and neighbors for quality entry door sales and installations.
