Sign Waterproofing Inc.

These guys are great. Yong repaired and waterproofed two old balconies in our building in four days. The balconies were 35 years old and had never been waterproofed. There was extensive rot and termite damage that only became evident after Yong opened up the decking. The price was very reasonable. They did everything they promised and went over and above the contract specifications. Would highly recommend them.
