Edgar Li was the fourth and final provider that provided us an estimate to replace three of our exterior doors: Front door, back french doors and back patio door. He was communicative, punctual, and straightforward. He was able to meet the least expensive estimate, but I felt that he was more detail-oriented than all of them as well. His installer is an employee and has been for several years. He was here all day, installing the two back doors. He ensured that the space was tarped off, so that no dust could get in the rest of the house, and that it minimized inconvenience. Mr. Li stopped by a few times to check in the work – everyone was fantastic. The installer came back on another day to do the front door, as it was special ordered and needed to come in. This time there were two guys, and my double front doors became one beautiful door with sidelights. I most appreciated the attention to detail and level of customer service that Mr. Li and his employees provided. This is a small, local, well-run business, and it was a great experience all around.
