We used Crystal Exteriors to replace our entry door with French Doors and a transom window above the door. The new doors and transom window look stunning and actually exceeded our expectations! Working with Edgar Li, the owner of the company, was a real pleasure. He is friendly, knowledgeable, and very responsive to all questions and concerns. He and his team delivered the highest quality work and service and we will happily work with them again.
