Yong and his team very knowledgeable in waterproofing and professional. They have top class customer service and I would not hesitate to hire them again! Sign’s Waterproofing answered all of our questions. They started on time and finished the job on time and throughout kept up with communication of everything they had completed they found 3 cracks in the area they assessed was the problem area and addressed diligently sending photos as they progressed.

First of all, I was looking for a company I could trust, they met the bill. They were prompt and that was appreciated. Yong is also very kind and patient to answer every detail and every question. Highly recommend Sign Waterproofing Inc to who need basement waterproofing service.

We hired Sign Waterproofing Inc. Yong came in and with one look around the house and the area ... suggested that it is not the foundation issue but instead it was chimney from where the water came in and caused crack in the floor/ slab at one corner. Yong suggested me to call the Chimney specialist and I did so and have verified the same with the Chimney specialist and infact there was this loose brick issue from which water was pouring in and which in fact caused the issue. Fixing the chimney (loose brick issue and caulking near the exhaust) and I am very much pleased and impressed with the Sign Waterproofing Inc. I would highly recommend Sign Waterproofing Inc for their honesty and for high professionalism. I am definitely a very happy customer. Thank you Yong.

Yong and his team is excellent. They came on time and after work was completed they did very good job in cleaning and putting patio stone back as before. His team sealed edges of exterior windows which was not part of the contract. I am very satisfied with overall work.

We talked with business manager Yong. He is very professional to answer our problems. Then, we made a decision to hire Sign Waterproofing Inc.

We hear from my friend who Sign Waterproofing Inc did theirs before. They gave Yong's phone number. He is very nice and friendly when we met up. Then, Yong tested an area we found for mold. Scheduling was a breeze and they called to confirm our appointment the day before. The Sign Waterproofing techs who arrived was on time, polite and professional. Once the results were in, they contacted us again to be sure we understood the lab reports. As it turned out, it wasn't mold and therefore, we didn't need any further services. I would definitely recommend Sign Waterproofing Inc!
