Edgar Li did an outstanding job of installing a Pro Via single metal and double fiberglass French patio doors in January 2015. The workmanship was outstanding. Mr. Li is a very fine businessman,very knowledgeable of the products he uses and very thorough about explaining options and best product for a specific area. He responded quickly to our inquiries and completed the work on time. I plan to have him install shutters soon.

(Found on CheckBook.org) Like many of you, you employ some contractors that are decent but you have a select few contractors that you would recommend to anyone without hesitation. Crystal Exteriors is one of the latter for me. You get to deal with the owner, Edgar, directly. He communicates very well and is responsive. It was no problem for Edgar to give me an estimate on short notice, and the project was completed exactly as promised without a hitch. If you want a smooth job with personal attention and no drama, go with Crystal Exteriors.
