Crystal Exteriors replaced my front door. The owner, Mr. Edgar Li, was very friendly, always reachable and responsive by telephone and email, did not try to pressure me into buying more expensive products or additional products besides that which I wanted, provided sound advice on product options, and his installation crew was very neat, thorough, professional, and did an outstanding job. I will certainly hire Crystal Exteriors again in the future for other home improvement projects.
