Get matched with top foundation repair specialists in Mercer Island, WA

"I just bought a new house, where one room had a noticeable slope in it. I believe it was because this room used to be the garage before a remodel. I had RamJack come out to check it out to make sure there was not an issue with the foundation. They showed up and looked at the room, checked out the outside and performed some tests with their instruments. He could have scared me and told me that I needed lots of work, because honestly I have no idea about foundations and I was willing to pay to fix the issue on my new house. However, he explained to me that he did not believe there was an issue and that the house was fine. He said when I replace the carpet, to have the flooring people level out the slope and that should take care of it. It is great to work with those who do their best to give you accurate honest advice and not try and use your lack of knowledge against you. All of this was done for no cost, and that is what puts the cherry on top of this story. I know if I ever do have any issue, RamJack is the first place I will call, since if they tell me there is any issue I can trust that there really is one."

"From consultation to completion the team at Groundworks handled our foundation repair with care and professionalism. Matthew came to the house and stayed to answer every question and explain every detail. He took the time to complete a bid while onsite and walk us through the process. (BTW their permitting department and financing through GreenSky really helped!) When the work started the first team of Alex, Iuni and Luis, were exceptional (they pier leveled the footing). We got texts the moment they arrived at the property and they got right to work, completing their part right on time. They worked as quietly as possible and kept us informed of the progress. The second team for foam leveling our slab and led by Daniel, got it all done in part of a day. They were also courteous and even helped move furniture. When the work of both teams was finished Alex, the foreman, walked us through an inspection and answered all our questions. Finally, Matthew circled back at the end and made sure"

"If you want the best this is your guy. Rome and his crew installed a slab in my crawlspace storage area. Yet they treated it as if it was my living room. Or better yet, their living room. I’m pretty sure that they are going to get their projects as close to perfect as humanly possible no matter what the intended use is. Plus they clean up everything. And I mean everything. The only way to know there was a concrete crew on my property is they that left behind an expertly finished slab. So I’ll say it again. If you want the best this is your guy."

"It went very well. The final product was fantastic. John even helped fix the storm drain issue we encountered. He did it all."

"Felix and Carlos cleaned, pruned, weeded and beautified our yard after the long winter of winds. They worked hard all day to fix up our 9,000 sq. ft. yard. We will contact them for future projects. They are a talented team and eager beavers!"

"I have never seen such a great company before. They transformed my whole back garden. It was exceptional work and our garden is unrecognizable, idyllic in comparison with the way it was before. I can not recommend this company more highly! If there were infinite starts available this company would get them. I am very very pleased!"

"Wu Construction did an excellent job for us. Greg estimated what work needed to be done and we scheduled it as quickly as possible. The crew was on-time, very efficient and did a really nice job keeping things as clean as possible, which is no easy task when repairs are done to a wet & muddy foundation area. A full interior perimeter drainage and sump pump system was installed to eliminate standing water in the crawl space. The crew also removed all old floor insulation and installed new R-30 insulation. The crawl space was completely cleaned up and a new vapor barrier was installed. Everything was completed as agreed upon - all at a very fair & reasonable price. The crew even installed a permanent access ladder to the area so it would be easier to get into the crawl space area. I'd highly recommend Wu Construction for any drainage or foundation work needed to your home or business. Greg, the Estimator/Scheduler and Thomas Wang, the Construction Manager were a pleasure to work with. They kept us up-to-date on everything and were true to their word. I look forward to working with them again, as needed."

"We hired Thad, Jered, and Dan to put a water feature with a 4 tier waterfall. They also put new plants around the water feature and replaced our grass. They replaced our back fence and repaird the side fence. They did a fantastic job on our water feature. It looks so natural and is bigger than that what we were expecting. The plants were well chosen. We needed plants for a shaded area. The grass was put down with such care. The fence is nice and straight. We plan to hire them for our next project which will be brick work in the front yard."

"Island concrete did a fabulous job and completed the work on time as agreed. I would recommend them to anyone that needs concrete done. Very professional."

"Water had always been a problem for my crawlspace, especially during raining and snowing season. Asking around, installing a French drain and a sump pump appeared to be the solution. I searched around and picked Insulation Co. Estimation without inspection seemed weird at first, but it made totally sense since the foundation layout is all there in the files. Jo had always been responsive, detailed and nice whenever I had questions. Scheduling was easy and Rafael and the team did a great and efficient job onsite. 2 months after the installation, we noticed that there was still standing water and they came back to install more pipes and gravels. We really appreciate the effort."
