Sign Waterproofing Inc.

We have used Sign Waterproofing Inc. several times already for different waterproofing projects, and they always prove that they are the best waterproofing company. They have great crews, their backend office staff is also very responsive and on top of everything, and Yong and Victor are very easy to work with. Thank You very much

Outstanding company. We have used them many times on multiple waterproofing projects. Their manager Yong, is great. Always on top of things and manages each project with dignity and respect. Also theirs technicians are very knowledgeable and very respectful. Thank You for all the great work!

I recommend it with full confidence to everyone, I am very grateful for the work that Yong and the Infinity shower trays did, it really saved me when I was in a quandary when renovating my house.

Yong and his team did a great job when we moved in taking care of all the problems with the new house roof

Yong was the estimator for the project. He inspected the water leaking area and gave detailed drawings and cost involved in the work to be done. Not only did an excellent job but took pictures of what was done Excellent company from first phone call to finished job. Thank You Yong and Sign Waterproofing Crew.

Very professional. This team knows what they're talking about. They were willing to come out over Yong to help us in a waterproofing situation that was time sensitive. They have a lot of experience and correct leaks where other waterproofers have messed up.

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.

They have the best customer support. They are always there when I need them. They are the best out there. The inspections are always on point. They never hide anything from you. I love the way they know what they are doing. The value is great. I have met others that have not met up to my needs like they do. Great reliability. I have never had any doubts about them. I love what they do and stand for. I have nothing but great things to say about Sign Waterproofing Inc. and their company and what they stand for.

Yong is Extremely responsive. First priority was willing to go over inspection in fine detail, answer all questions and provide further professional recommendation. Yong also provides clean up and remediation services. Reliable and trustworthy. After the project done, the water leaking issue is solved. Great customer service!!!

Sign Waterproofing Inc is a Excellent company- very knowledgeable, well versed in details needed to assure quality work and able to explain the scope and costs to expect for my project. Very reliable, focused and on time! Administrative details were handled with expertise, even with unexpected changes. Yong is also very helpful to find out the issue and resolve the problems.
