This is a follow up review. My first review, "5" Stars for a huge well done project last year January 2025. Josh came by recently to inspect last year's completed project; everything's dry, clean and air is moving throughout the complex maze of crawlspace walls as it should. Josh and his work crew are diligent, knowledgeable, thoughtful of work space management, keeping things clean from start to finish. Chances are if you live in Cowlitz County, you have ground water needs. A call to Advanced Waterproofing will be your best solution to correct any water issues, big or small. Thank you Josh and crew! You are an answer to many prayers. read more

Josh and Company do amazing work. They are very meticulous in worksite organization and cleanup. They added runners to inside the house - on path to bathroom - and never left a mess. We had craw space insulation, pipe insulation, foundation crack repair, girder support footings replaced, and 10mil vapor barrier installed. Scott read more

We have an older house and have needed some support restructuring and repairs for some time. Josh with AWP came out as scheduled and inspected the job. He bid the job originally at about 1/3 of Terrafirmas bid and included more work than the competition. Josh was communicative and easy to work with for prioritizing the most important needs and keeping the job affordable. As expected, some additional issues arose during the job and AWP's team was able to handle everything our old house threw at them with ease. Structure, supports, excavating, cleaning, plumbing, concrete, fabricating and leveling, AWP did it all for us. It was a full work job and I'm glad I called Advanced Waterproofing to get it done for us. read more

Josh and his team installed a sump pump system for our basement flooding issues. During the installation, Josh took the time to explain each process and even offered me to see the progress at each step of the way. Josh and his team honored our contract throughout the installation and they made sure to communicate any issues they encountered. We had one instance where his team started working on something prior to contacting me; however, Josh held true to our contract and ended up eating the cost of an additional 4-6 hours of work. We truly appreciated Josh's candor and humbleness dealing with this issue. Overall, Josh and his team were very friendly, organized, and tidy from start to finish. I highly recommend Advanced Waterproofing's services! read more

See all

Working with Josh and his team was one of the best experiences ever. They came through for us when we were in quite a predicament with timing on a house we were selling and they were professional, rocked the job, and honestly we were blown away with their work ethic and skills. They went above and beyond for us to ensure we had the crawl space in top shape. We would absolutely recommend them to everyone we know, and we know that they will come through and be the best experience for you too. Kudos to Josh and his team, you guys are truly awesome and we are so grateful we got the opportunity to hire you!! read more

AWESOME JOB. We would highly recommend Josh and his team to remediate any crawl space need. Very professional and courteous crew.

I contacted AWP to come by for a bid on my houses insulation in my attic and crawl space. The first appointment didnt work out as they didnt right down my appointment time correctly, should have been 930-10 but they said 3. We rescheduled and when the day came they never showed so I called them back. I was told 15 minutes out and was abruptly hung up on. I waited afew minutes and received a call stating today wont work out sorry and never got a chance to reschedule. The best and hardest workers with the greatest quality work is nothing if they never show up. This was a significant waste of time for me as I work alot so I will not be recommending these guys. read more

Very Personable and Professional business! Great pricing and willingness to go out of their way to meet my needs. Most importantly the owner's heart matches his quality of work. This is so hard to find these days! I will use them again on future properties, friend's and family's homes! Do yourself a favor and don't go anywhere else for waterproofing, foundation, ect! read more

I hired Josh and his crew to repair some storm drains. I thought Josh did an excellent job communicating with me throughout the process and the work was top notch. He even did a few extra small concrete patches for no charge. Josh is a great guy and he has a great team. Thank you! read more

Called to set up a time for them to come out. He said he was on a job and to text him my information and he would call the next day and try to make it out that next day. He didn't call back for over a week. I was out of town then so called back the following week. He told me he would come out the next day to look at what I needed done. Never came or called. So I sent a message asking what the deal was. He called back and said he would call me at 4pm and either come out then or the next morning. Never heard anything back again. Terrible customer service and business practice. Called cascade electric and plumbing at 815am yesterday morning and they were at my house by 10am. Clear difference between a well run business and a portly run business. read more

This winter I had a water leak that ruined my hardwood kitchen floor. Josh found the leak under the house. He did extensive water removal and cleaning in the crawl space and also knew the best procedures for dehumidifying the kitchen. The damage was extensive and AWP was able to remove and replace my cabinets, flooring, and move the kitchen island to take care of all the issues. Josh and his team worked hard daily "until the job was done not according to the time on the clock". I was comfortable with them working in my house. I am very pleased with the work they performed and my insurance company was impressed with the quality and efficiency. I highly recommend Advanced Waterproofing for any water damage repair work. read more

We would definitely recommend Advanced Waterproofing for any of your foundation issues. We had Josh and his crew replace 14 posts underneath our house. Josh and his crew were so professional. Their work area was spotless, and the cleanup was fantastic. Josh communicated great with us before, during and after the job. Good price on the job. Josh has a good, hard-working crew. We appreciated all the work. read more
