    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

    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

    We had been having issues with mold in our home and suspected that the crawlspace could be the culprit. I research companies ans contacted Groundworks. Joe Daleo came over and did a really thorough job of inspecting our property including our crawlspace and foundation. He found that there was moisture on one side of our property due to ground water settling. We decided to move forward with encapsulation after feeling confident with the information that Joe provided. We waited about a month to get started as we had some other home projects we needed to get done first. During that time, Joe maintained communication and I was able to reach him whenever I needed, which was awesome. When the work started, Brandon and his team, including Edgar, Alberto, and Jose all showed up with a smile. Brandon gave me regular updates and pictures of what was going on with the work. Whenever I encountered any of the guys, they were always polite and professional. I know it was difficult work to be underneath my house for eight hours a day and I couldn't understand how they could still be so friendly and genuinely happy. Joe Daleo continue to be in contact with me during the project and came over to check on the work that was being done. Since the encapsulation was completed, we have noticed that the temperature of our home stays more regulated and the musty scents have dissipated. We also noticed that the rooms on the side of the house with the moisture used to feel muggy and now they don't. We are so happy that we chose Groundworks and decided to encapsulate our crawlspace. I highly recommend them!

    Nice and level!!

    See all

    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.

    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.

    This review is definitely long overdue. I reached out to Elite over the summer to help with a few…read moreresealing projects around my house, including a leaking window and an air gap issue with one of our sliding doors. Juan handled the work and was excellent from start to finish. He was professional, clearly experienced, and made sure everything was properly sealed and taken care of. The work was completed within the timeframe that was originally given, and the results have held up great. There were a few minor hiccups when it came to confirming schedules as they came to quote but took a week to get a proposal and then another two weeks for an appointment, but honestly the quality of the work made it worth the wait. Overall, I'm really happy with how everything turned out and would definitely recommend Elite to anyone needing similar work done.

    This review is long overdue. Elite was hired to waterproof a deck. The phone and email service…read morewere totally fine and the folks who came to assess the job were also great. The first time they finished the work, water was still pooling on the deck with some light rain. I complained, and they sent some folks over to redo the work. This second time they left the place pretty dirty, with painters tape half covered in waterproofing material which is still nearly impossible for me to remove. But the kicker? The work itself is still subpar. There's no primer under the paint they used on the door from the deck so it's peeling off. The water still leaks into the room below and I had to have someone else come and take a look at it. The edges of the work particularly where the deck meets the house were very poorly done. I'm disappointed that not only did they have to do the job twice, but the second time they left things so dirty, tape literally painted on, and never checked in or even had someone confirm with me the work was done. Having someone else come by has highlighted just how poorly this was handled. I wouldn't ever go back to these guys.

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.
