Get matched with top foundation, basement or crawlspace waterproofing / encapsulation pros in Washington, PA

"This is the second time I’ve used Advanced for my basement waterproofing needs and they were again fantastic. Work was done well and it was easy to schedule. They are low pressure so if you have a project and just need to get an opinion, reach out to them. Chris is great and very attentive and helpful. Both of my waterproofing jobs still cost less the the initial job from one of the big companies, so I was really pleased with their work and price. They did a nice job cleaning up (but concrete dust gets everywhere so I still have work to do). Highly recommend!!!! I also live in a township with strict permit codes and they knew to check and help with that process (the other company did not)."

"I have several properties I own in the Pittsburgh region and I only use G&J. They have worked on 4 different properties for me and although u prefer not to have water issues, it is always a comfort to know i can call somebody I trust. They have great communication and have done everyone of my projects on time and exactly how the promised. It is easy to recommend them because I have had nothing but good experiences."

"Kevin was extremely available and very easy to work with. Great industry knowledge and performed the work quickly at a great price."

"Successfully completed the job! Basement is dry. A warning about the amount of mess and leftover dust would have been nice, but overall, a job well done."

"Robert Yoder came to my house to do my yearly check up today 10/14/2025 He was such a nice out going person and very pleasant to talk to. He was very detailed on what he did and took pictures of what he did. He must of asked me 10 times if I had any questions or concerns ( as he was going through all the stuff that he did) about anything, which showed he really cared about me (the consumer) and his line of work that he does. You can tell that he is very passionate about his job.Thank you Robert for your customer service Sincerely K.E."

"Very Prompt, The crew was very organized "

"I couldn't have been happier with the whole experience dealing with ABS. From the initial quote to scheduling, the actual installation and follow up were all excellent. The price was very competitive and included more site prep than any of the other quotes I received. I would not hesitate to recommend ABS to a neighbor or a friend, or use them again for another job"

"The guys that came and did the actual work were very nice and did a great job . The problem was the management from Bill and down to Travis , my basement has a toilet that could not be moved .. well by the floor being jackhammered damaged the toilet it now leaking because of hairline cracks at the base , after contacting Travis and sending pictures to him their response was we will send you $100 and you can buy a new toilet ! When Bill bid the job he made sure to tell me about how they are insured up to 2 million dollars Thst $100 dollars doesnâ t really buy a toilet and then the cost of getting someone to install it will be hundreds more for that reason of them not wanting to take care of what they damaged I would not recommend ABC to anyone they got their money snd could have cared less about my issue !! Poor communication with this company and also the broom swept my basement I sm still trying to clean up the mess and it has been 2 weeks very disappointed ! I guess I should say buyer beware !!"

"Zach mis measured a foundation on step #1, made the wood structure fit in the cheapest and laziest way. Concrete pillars were supposed to be hidden under the shed (I also supplied a drawing from another contractor to go by) and they now extend past so I am not able to just easily landscape around them as well as some of the brackets literally hanging off of the pillars. A couple of the concrete screws did not draw down all the way, a normal person would find out why and fix but nope they left it this way, pictures in the link!! The foundation was not square and it is to wide as well due to this mistake. I also had to shim multiple areas due to the foundation not being level. He promised to come back and help with some landscaping and some sort of flashing on the back to help hide the mistakes and most importantly keep water off the wood, I even had him give me a paid receipt saying he will return to help and then disappeared. I have linked pictures and a video of the terrible workmanship. Would not recommend. A follow up and help with some of the landscaping would have been very appreciated. { Removed google link}"
