Get matched with top foundation drainage installers and replacers in Benicia, CA

"Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!"

"I am incredibly pleased with this company. The entire crew were 100% professional. The owner of the company took time to answer my homeowner questions as they came up. He was very patient and thorough. All the men on the job worked incredibly hard and stayed on task throughout the project. They installed the French drain, installed a washout and removed an old deck all in a weekend. I would most certainly recommend them."

"Mike showed up asap, scoped the job requirements, gave a written estimate that was accepted by insurance company, had team out next morning to roll up rug in bedroom, break through concrete floor, locate actual leak (~6" laterally from where professional had estimated it to be) and about 18" beneath floor surface, repaired pipe, pressurized system to check it, however repaired pipe leaked (crimping a fitting onto corroded pipe didn't work), then properly cleaned, sweated new piece of pipe into place, repressurized system, inspected new work to verify success, filled hole with sand, covered and leveled that with freshly mixed concrete. All was completed in 1 day. Kudos. Thanks, Mike! Your timely response was greatly appreciated! Mike's bid was higher than that of the leak detection company; however, Mike's company was far more responsive to our need for hot water and was there the next day. The lower bid came from a company that wanted us to wait 21 days(!) for them to repair it. Since we had an understanding insurance company, they were willing to pay the higher cost for our comfort and convenience. That's right! You read it correctly. An insurance company that looked beyond their bottom line to put our needs first."

"The Right Choice! They have incredible taste and design ideas. They made my dream kitchen come true. I enjoyed working with Mishel (cabinet maker) and also with Natalie (interior designer). They helped me to be able To visualize my kitchen before we even installed it 3D design and samples. I already felt i had it installed. We selected all the materials and doors. Very detail."

"Overall, it went excellent. First and mainly, after over 4 months, we are simply delighted with having this liner in the crawlspace. Allergies that were bugging me for the past 7 or so years are gone. Can't say it will affect others that way, but for me, it did -- granted, we had done a lot of research and also cleaned up down there thoroughly prior to finally installing this liner. The liner was the final touch, the part that we did to help maintain the cleanliness.
John, the person who comes to give the estimate, won me over completely; he's just very honest and sincere. And that was the final point that made me decide to go with Clean Crawlspace and not another company that had come to give an estimate. I'd read that Clean Crawlspace prices are more sometimes, but for us it was only some $150 more, but that was worth it to me for other value I felt we would be getting.
David, the owner, is simply wonderful to work with too--so nice and accommodating. I had many questions before we started and he responded quickly and thoroughly to my inquires.
The job took 4 full days. We had some tricky places to seal in, where our cinder block base around the perimeter was missing and the foreman was not sure of the best way to proceed on those (though he had ideas), so he erred on the side of caution, until he was able to get David's advice. There was a little miscommunication between us and foreman in that regard, but David cleared it up immediately via phone, and bent over backwards to be sure we were also satisfied. They did everything and went beyond the call of duty to be sure we were comfortable and satisfied.
John came out and checked everything, too. He also offered to come out during the rainy season to check the tricky areas. They are confident it will be fine, but he offered to do this to give me peace of mind. (That visit hasn't happened yet, since there's not yet been rain.)
I'm just very pleased with the product and the customer service, which is excellent. They are like your friends.
...One note to be aware of: after putting in the lining, after about 3 months, we noticed that the oak floor (original from 1948, with the nail holes in full view and everything) must have dried up some as there are now cracks between the wall and the oak floor that were not there before. It is not everywhere and in the widest area it is only 5mm. Our general contractor was here the other day, and he agrees with us that it must be from the planks drying out, from the reduction of humidity in the crawlspace. I don't know if that would happen with newer floors, but it is something to be aware of. Anyway, we have no problem with this, and plan to simply apply some oak-colored caulking, because the reduction in the humidity and the disappearance of those irritating allergy symptoms has been WELL worth this little inconvenience.
We haven't yet used the crawlspace as a storage area, but it is definitely possible with the lining there. Needless to say, service workers who've had to go under there are thrilled with the liner (we had to have a plumber check something, and also a pest control check something). My husband is hoping that he won't have to go under there anymore, anyway, with all the clean up and the final point of this liner keeping it all clean, and so far, so good.
