I cannot say enough positive things about this company. Edgar Li and his staff were truly professional and did an amazing job. They completely cleaned up the areas after the job and were careful not to damage my walls etc. while removing the old doors and installing the new. He is the best contractor I have ever used. He was in touch every step of the way and worked around my schedule to install a beautiful ProVia front door and 2 deck doors with internal blinds. The product and labor were excellent. Mr Li came out to check the work after the crew finished to make sure everything was done properly and I was totally satisfied. His price was fair and less than another estimate for the same doors. I would absolutely recommend Crystal Exteriors.
