Worked very closely with Mr. Li in selecting the proper door for our house. He was extremely professional and very detail oriented. He provided us with options, one of which was to remove the storm door and just have a wood style door. His recommendation was excellent. the new door on the house has so increased the curb appeal of our house. In addition, his staff was very accommodating in the installation of the door. I would highly recommend Mr. Li and his company for any subsequent work on our house.
