The Monster Crew from Groundworks.
Eric T.

They easily fixed my long-standing downstairs leak. The crew was efficient and professional. Highly recommended.

Chi N.

Red flag !!! Don't use this company for foundation work or any work on your house.They did my foundation repair and leveling the house. none of the work was done correctly as plan and now the house it worse than it was before the work was done .more cracks on the foundation and didn't level out the house and my house started to buckle where they did the work at and none of the Intel jacks are tighten up to hold the house up and now i'm worried it might get worse before they fix it. They requested us to pay in full when the work was done. That's a scam. when the final inspection is not done and no paperwork Now we are waiting on them to find a solution to fixing our house.it been 2 weeks now still waiting Will update this post after the solution

Slab that holds swim spa
D W.

Absolutely amazing how these guys come out and raise your patios is short time. Anthony and Brian just knocked it out. Got her on time where very nice to deal with and they got right to work and raised my patio slab (1 1/2") in such short time. They cleaned up afterwards and left the yard in excellent shape. I was very impressed with their professionalism. Special shout out to them both. Just dealing with Groundworks from the initial appointment with Mr Dalton, to getting a great estimate to having good guys fix my patio. I highly recommend Groundworks!

The team at Groundworks did a stellar job fixing my house's concrete stairs. They were very professional, knowledgeable about the process and were vey informative through the procedure. Big shoutout to Alex Campbell and Juan Pablo Hernandez who performed the work professionally at every step, from preparation to clean up. Also, a shoutout to Jim Dacpano, John Dalton and Dan Cartieri who assisted with the work ensuring smooth execution. I would 100% recommend Groundworks for any work related with leveling and fixing concrete stairs. Their customer service and attention to detail are superb Over all, the team delivered the job professionally

Do you service Stockton by any chance? Off Benjamin Holt Drive / I-5?

Hi, thanks you for messaging us. We do service the Stockton area for Foundation Repairs. Feel free to call to call us and schedule a free estimate and inspection. 707-310-0602

Hello do you guys do estimate for load bearing wall removal with possible power beam install, we want to do a kitchen remodel and want to know out a load bearing wall?

Hi Juli, this is not in our scope of work. We recommend you contacting a structural engineering firm.

Hi! Do you guys do re-leveling of mobilehomes/manufactured homes in Antioch, Ca? If yes, how much on average a doublewide would cost? Thanks!

Hi Jona, if the mobile/manufactured home is on a pre-existing foundation (not on cinder blocks) then we can help level/stabilize. Otherwise, that is not in our scope of work.

Do you replace screw jacks and piers? Ours have shifted and some are floating due to shrinking adobe soil. Thank you.

Hi Barbara, we do replace screwjacks and install piers. Please contact the office to schedule an inspection and quote at (707) 310-0602.

I sent email to Hannah regarding my foundation work done by Bay Area Underpinning and having foundation issue after the fix. The email is bouncing back saying Hannah not found. Whom should we communicate the issue?

Try 707-310-0620 (main number) or Darren at 707-315-2532

We had a shed installed in our backyard and even though I approved placement, my husband is not happy. It needs to be pushed about 4" back and 4" to the side on a cement pad. Can you help? Can send pix....

Hi Pam, thanks for reaching out! This is not something that we do. We lift and level settling buildings. We recommend you contacting the company who installed the shed.

Hi do you serve Brentwood 94513?

We do serve Brentwood!

BAMC just finished encapsulating our crawl space and updating our 2 old pumps. Bill was the one…read morewho came to take a look, and he was fantastic to talk with. Our house had a mish-mash of prior attempts to mitigate water under the house, and I felt good that Bill fully understood the complexities of the existing situation and offered a couple of solid options to deal with it. We did end up choosing the full encapsulation (to just finally be done with the issue) but I did not feel pushed in that direction at all during our conversation. Once we decided, working with Gina in the office and Bill to get the details of the plan finalized was easy, we got our dates locked in, and on the scheduled days Antonio and crew showed up on time and cranked through the job. Everything was finished exactly to the plan Bill had drawn up, including the interface to the existing parts of the system we wanted to keep. And the crawlspace looks incredible - truly a major upgrade to our home. Looking forward to a rainy season finally not worrying about it!

We hired Bay Area Moisture Control to install a sump pump with trenching to address standing water…read moreunder the house. On the positive side, the crew (Antonio) was punctual, easy to work with, and efficient. The whole job took 3.5 hours. The issue came with the placement of the sump pump discharge location. I had talked to their sales lead (Bill) about having the water be discharged to the street where there is a storm drain. Instead, the sump pump "pop up" was placed 8 feet from the front of the house, way too close. Water can flow back under the house, defeating the purpose of the sump pump entirely. When I called Bill during the job to talk about our options, he dismissed our concerns and immediately pointed to the contract, implying that this was our fault because we signed the contract. In reviewing the contract, the design was completely unclear about where the sump pump would exit water. Bill continued to skirt the fact that that we had discussed pumping water to the street, and instead, he baked a different design into the contract with unclear markings. We are dissatisfied with the poor communication, but even more so, the lack of accountability from the company. If you hire this company, just a word of caution to walk through the design with them before signing and make sure you're on the same page about everything. We are going to have to bring someone else out to fix the issue. One more thing ... I was flabbergasted that when talking to Bill on the phone about the iffy sump pump discharge location, Bill was trying to upsell me on encapsulation! Read the room, dude.

i cannot say enough about what a good job the crew that did my work was. They were kind curtious…read morepromp and very professiona. I work in Real Estate and would advise my clients with Foundation issues to use this company. NorCal Foundation did a fantastic job. Sincerely

I contracted Norcal Foundation Support in July 2025 for what was supposed to be a two-week, $52,130…read morefoundation stabilization project at my hillside home. What followed was nearly a year of mismanagement, broken commitments, and financial consequences I'm still dealing with. They no-showed on the agreed start date. I called them at 10am to find out why -- they told me they were stuck on another job. No warning, no proactive communication. It only got worse from there. The job stretched into months of sporadic work. Midway through, they told me they needed a subcontractor for core drilling -- something that should have been identified during scoping -- then let months pass without scheduling one. My property sat in a hazardous state the entire time: open holes covered only by wood boards, piles of excavated dirt, debris, and equipment surrounded by caution tape. My homeowner's insurance company conducted a routine inspection, found the condition of my property unacceptable, threatened to drop my policy, and ultimately imposed a $2,000 surcharge. Resolving that took significant time and effort. Faced with no resolution in sight, I was pressured into accepting a reduced scope of work -- specifically, no tiebacks. Tiebacks were explicitly included in my signed contract and shown on the job drawing. Without them, there is no guarantee my home will remain stable on the hillside. I paid $52,130 for a project that does not solve my problem. After agreeing to the reduced plan, it took more months to redraw plans and pull permits, then more weeks to schedule the final visit to seal holes and reconnect drainage. On that scheduled day, they no-showed. Again. When they arrived the next day, they left without finishing. Their excuse: my gardener had told them not to proceed. My gardener -- someone I know well and trust -- told me he said no such thing. Norcal did not just take direction from someone with no authority over my contract. They fabricated an excuse to walk off the job. This company demonstrated the same pattern of behavior from the very first day to the very last: no communication, no accountability, and no follow-through.
