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.
