Part one of a two part foundation project Recently we had our house foundation repaired by Groundworks out of Fairfield. One bedroom had sunk by almost 5 inches as that part of the house had been built on fill. In order to restore the house to it's proper level numerous foundation jacks and floor leveling screw jacks were required. In addition some landscaping bushes and pvc sprinkler pipes had to temporarily removed. Groundworks had informed me prior to starting work what would be required to successfully complete this project and had my full approval. The house is now level, the doors no longer swing on their own and the interior cracks between the walls and ceiling joints no longer exist. Prior to the crew leaving the yard was cleaned up and the pvc pipes replaced. Best of all Groundworks will come back annually to the next 5 years and make any necessary adjustments. The Groundworks crew that made this happen was Andrew, the site supervisor, Charlie and Allen. Their performance and daily communication was superior on all levels. This is part 2. The Groundworks Poly crew of Anthony & Brian were very fast and efficient in completing their part of the foundation repair contract which was to level our family room slab floor. Fast, yes, but Anthony did take the time to not only explain what they were going to do but also walked me through the process as they were working. I have no problem in recommending them & Groundworks to other home owners who need to have their foundation repaired. read more

I hired Groundworks to repair the cracks around my in ground pool. The pool was installed in 1999 and is still looking good, but the concrete structure showed its years and had linear cracks in places and one place the concrete shifted about a quarter of inch. So I thought I would have it repaired for beautification purposes. Brian the representative that came out is a fast talker and didn't explain the process of what Groundworks would and could do to improve the cracking of the concrete floor! I certainly thought that after paying $4000.00+ dollars I would be able to see a difference in the concrete. I didn't see no difference other than some lifting on the crack by the steps of the pool. Another problem I have is their is overspray of the polymer on my privacy fence. I know it is from the polymer because it is where they sprayed by the steps and diving board. I'm certainly not happy with the outcome.The crew that came were here approximately 1 hour 33 minute. WOW 4000.00 dollars just choose wisely ask a lot of questions make sure you understand what the process is. I will not refer them Stayprayedup DP read more

Absolutely the worst Company! DO NOT USE! They failed to correctly underpinning under the house & refused to remedy it for 6 months, causing me to fight & fight & fight to get it right, all the while my home was being damaged from bowing in the middle. They're now ghosting me causing more wasted time. The "owner" and management have not contacted me. Your management is rude, workers careless, & the entire company non-responsive. TERRIBLE COMPANY. DO NOT RECOMMEND. read more

They did so well with our foundation repair. They were kind and courteous during installation and cleaned up everything. Their price was the most affordable and we compared 4 companies. read more

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 read more

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! read more

Groundworks - Slab that holds swim spa - Masonry/Concrete Near Me - Fairfield, California

was very nervou about an older home we were looking to purchas. we set up an appointment with Groundworks for 4/1/26... The inspector that came out was Enrique Vera. He was punctual, prepare and communicated well about the appointmen. when he arrived, he explained in detail what he was gonna do and look for. He was incredibly professional and friendly the entire time. He spoke to me in detail about everything that he found and gave me his expert advice on it. Enrique was incredibly thorough and had great knowledge of the job in the end. He found nothing he felt was in need of immediate repair. I was absolutely not expecting that. He also provided me a time line of what to look for in the future. if given the opportunity to get an estimate would highly recommend Groundworks and especially Enriqu. read more

ABSOLUTE GARBAGE COMPANY RUN AWAY. We got a quote in October of last year, they said they would start in December. They started in February and only came to work on the days it was pouring rain, with weeks going by in between them working on our property. It became apparent they were on a job at a house they did not want to make a mess out of and they chose to work on ours not caring about destroying our whole front and back yard. Not to mention the portopotty that sat at our home for 3 months. It's now May, they still aren't done. They did their estimate wrong and would not cover the cost of their mistake so they cut corners and now the city will not approve the work after they have been 'done' for a month now. There are chunks of concrete left around my yard, the house still is not level and we cannot get anyone to come out to fix it. We will be seeking legal counsel to sue. Check how many complaints they have to the BBB, they are a sham. read more

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 read more

I've given 2 stars in recognition of the work they did for me as Bay Area Underpinning. However, Ever since they were acquired by Groundworks they've fallen off a cliff. Over the last two years I had to chase them to even respond to my request for a quote, then to get them to show up for the quote, and then to try and get them to respond to my voicemails and emails. Groundworks, why won't you return a paying, existing customer's calls and emails when they're trying to give you more business? Furthermore, you aren't honoring your warranty by refusing to support your prior work. Stay away from them. They appear to be totally dysfunctional at this point. Maybe try another location. read more

Just had a poorly communicated conversation with the receptionist. She seems to actively want to dissuade people from working with your company. I would not recommend Groundworks for the rude behavior. Can't imagine what the service would be like had I gone through with it. read more

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! read more

5 star service from beginning to end! From Zayne in sales to Foreman Luis G to co-Forman Ken H to installer Mark P the service never stops. Honest, reliable and professional in every way. Thank you Groundworks! read more

Company rep came out to house, I explained what we were looking to do. He took measurements but really wanted to do the whole house. He said he would get back to me after he sent it off to the engineers. I never heard back from them again. I did get an email stating to "let us know if there is anything we can do". How about sending the requested quote to start with. Waste of a morning. Look elsewhere. read more

If I could give a zero I would. I'm a real customer. I've heard great things about Bay Area Underpinning from friends. It got bought by Groundworks and the owner lives in Virginia Beach which should be a hint it doesn't care about customer service. We initially had Bay Area Underpinning come couple of years ago and they said our foundation was okay. No work needed to be done, but earlier this year Underpinning came and said we needed helix piers installed ($100k). Now looking back I would recommend getting a 2nd opinion including a structural engineer. They completed project and wanted final payment however they did not schedule final inspection and it's been almost 3 weeks since they were done. It took a lot of phone calls and emails with minimal response. We spoke to Will from customer service who finally got our debris removed from our house after it was hanging out for a week. But now crickets when it comes to final inspection which worries me because they already poured back in the concrete. There are other issues to mention but not enough time read more

Reached out to Groundworks on 3/18, was able to book us an appointment the following day. Richard came out and was very helpful, knowledgeable and answered all of our questions and concerns. read more

Groundworks does their own inspections and services - the issue with this is you are certainly getting a biased assessment. I would HIGHLY recommend that anyone considering using Groundworks' services gets an inspection by an independent structural engineer BEFORE paying a cent for any services/foundation work. We luckily did so and found Groundworks' measurements to be wildly inaccurate and the work we actually needed to get done to keep our home structurally sound/safe is about $70-80,000 dollars LESS than what they quoted us. If we had moved forward with the services Groundworks recommended it would've ruined us financially and it would've been completely unnecessary. The people we spoke with at Groundworks were nice, but unfortunately their business model is essentially a scam. ALWAYS get a second opinion!!!! read more

Did not have any work done yet. They sent Howard for an inspection. Super knowledgeable. Honest (rough) estimate of scope of work to be done due to house leaning with cracks in walls. Based on Howard's knowledge and experience we need to discuss options for corrections. Thank you Howard, it was nice to meet you. read more

Everyone from the customer service reps to the supervisors (who inspected my retaining wall and came up with best plan of attack)and the workmen were amazing. They responded in a timely manner. Listened to my concerns and provided recommendations for optimum results. Rico and Corwin arrived promptly. Explained what they were going to do and completed the work on schedule. They cleaned up so well you couldn't tell they had even been there. Bonus. They took videos of the process so I could see everything as it was done. I highly recommend them. Thank you! read more

Ashton Price did an excellent job. He called ahead of time to let us know he would be a little late due to an earthquake ( ! ) happening while he was under the house he was working on at the job site just before coming to ours. While here, he addressed adjusting the equipment under the house where a new crack had appeared, as well as adjusting two doors that were not closing/locking correctly. He was very clear in explaining what he had done, removed some rodent debris where he had to enter the sub-flooring and was sure to keep everything clean and safe before he left. I would certainly recommend him to anyone needing foundation work !! read more

This company is a headache and similar to a car dealership. They just want to sale. They will upsale you fear monger you and promise it will go smoothly. The dehumidifier vibrates my floors the placed it near our bedrooms so guess who cannot sleep now! I was very specific with Tyriq about the noise I was assured I would not notice anything that was bs! I was told it would take 2-3 days well when telling the techs who were about to hit my popcorn ceiling that had asbestos and I let them know hey don't touch that asbestos on my ceiling (which I was having professionally abated at the time after the work with groundwork's it was sealed and i simply requested them not to agitate the popcorn ceiling as when they were bringing in materials, they were so tall about to hit the ceiling) well the young crew left without letting us know as they were nervous about exposure to asbestos... so that tells me the company does not educate their crews about asbestos and the fact that when they're working under houses, they are working very closely with asbestos in certain houses...our house however didn't have asbestos underneath it where the work was being done, I had a popcorn ceiling that I was afraid they were going to agitate it with their materials while walking through my house that resulted in no one coming for about 2 to 3 days. That's on the company not the crew. It's not fair that they did not thoroughly educate their crew and they didn't understand the difference in that. Then the work was said to be finished. When in fact, my husband went under the house and looked in the work was unfinished. They also cut my Internet line when putting the dehumidifier down there and leaving it disconnected. Well they came back yesterday. After a few weeks of me thinking the job was done. They put the dehumidifier not where it should be located in our contract plans and it is loud and vibrates my floors and I hate it. I wish I never went with this company and I wish they would just take all of their material back and give me my money back. I am afraid that this company will not hold up to their warranties and not hold up to anything that they have said they are a scam and they just want to get your money. We were very specific with Tyriq about how we had just had trouble with another company and their expectations and how we were completely blindsided by them. I was very thorough about this and how we were actually weary about going with the first company that we software quote and we were assured over and over again this is the only company that can do this and how their teams are specially trained, and know exactly what to do. None of that happens. I'm a very unhappy customer. If I knew that there was going to be noise and vibration. I would've never bought a dehumidifier. I would've never had the encapsulation done. I would've just added vents do not use this company they will take your money. They will upsell you and then give you mediocre results. After further research has been done ourselves for nothing special and I also have learned that they treat their employees like crap. Shame on you to take a company like Bay Area underpinning that built their reputation and to just burn it all down because you're a big corporate that doesn't really care is absolutely ridiculous. This situation has me so upset. I'm now looking at legal help so I'm hoping that groundwork could just take everything and give me my money back and we can act like we've never even met each other. I don't want to email your feedback I want Tyriq to respond to my emails or to just reverse the whole thing and take your crappy material back! I want nothing to do with this company I doubt that they will hold up to their warranty or anything that they've promised. I'm hoping that I'm wrong and that they can prove different but at this point I just want to be done with this company. I don't want any of their stuff I want my money back. I feel scammed. It's not the crew they did good work the company is who I am not happy with I'm hoping your crew is not reprimanded for the failure you made to educate them and communicate with transparency read more

This company is the best. Juan Fundora spent a generous amount of time giving my home a thorough inspection and explaining to me everything I needed to know and more. Groundworks didn't try to upsell me services that I did not need. They were honest and straightforward. We need more contractors like these. This is who to call with your foundation concerns. read more

If you like having your time wasted by spending three hours with a salesman who knows nothing except how to scam you. I highly recommend you call this company. Just a PSA out there for folks who aren't aware, if anyone tries to shove a contract in your face within 20 minutes of meeting you for tens of thousands of dollars, and asks you "what can I do to have you sign this contract right now? " when your spouse steps out of the room, use your brain and send them packing. read more

Do not give Groundworks your money or trust in your home - I now seeing many other 1 star reviews written since they did encapsulation work on my home in February. I have serious concerns about if the work was done properly, and if anybody considered at all the type or condition of my foundation before this was done. It's impossible to get anyone who works there to give any attention to the matter, or to speak to anybody with any subject matter expertise. I consider myself an attentive, more engaged than average, caring homeowner, and I'm really disappointed in myself for falling for their sales tactics, and really disappointed in this company. read more

Excellent workmanship. Professional technicians. Clean &tidy. Went above and beyond. Will definitely use again for concrete leveling. read more

Groundworks - Nice and level!! - Masonry/Concrete Near Me - Fairfield, California

I wish I could give them zero stars. I don't normally post reviews online unless the business is really good or really bad. I had a very disappointing experience with this company. I scheduled an appointment for 9am on a Saturday and I canceled another commitment to make it work. No one showed up. I tried to contact them, and was told they would look into it -- but I never heard back from them on that day. I followed up again on Monday, but was told the same thing with no resolution. I asked if they can reschedule, but the customer representative said they cannot do it now. I called one more time the next day and left a voice message. Finally, received a call back past 5pm and was told someone will come to my house on Friday at noon. Yet again, I waited -- and no one showed up... This repeated lack of communication and professionalism has completely eroded my trust. read more

Stan Caylor, the representative was punctual, knowledgeable and thoughtful. My main project, to fix an uplifted corner of the patio which was a tripping hazard, did not fit with the type of projects this company does. However, Stan made suggestions and offered alternative solutions for the project. I was pleased with this gesture. I will recommend Underpinnings to anyone who has need of their services. This "free estimate visit" was one of the best experiences I've had with service reps. He sent a quote anyway of an alternative. Thank you Stan! read more

We woke up to 5-6 inches of water in our subspace on 1/5/26. We called Groundworks and they sent Max Gibson out within 24 hours to make an assessment and give us a quote. He was calm ( I was not) and presented solid data (math) to support his recommendations for sump pumps and trenching to stabilize the water issue and prevent further problems. He remained available and immediately responsive to my repetitive questions throughout the process and coordinated services with remediation crews and electricians. I am confident that Max saved us money by ensuring services weren't duplicated. The crew working under our house was equally purposeful and patient. Erick Baez and Tejon McGee spent several days under our house and in and out of our house. They were respectful of the environment at all times. All work environments were covered with plastic and they wore gear to protect themselves and our home. They tidied up each evening when they left. Communication was tight. Erick, Tejon, Max were all on the same page from day 1; They had a plan and worked the plan. I had some anxieties about possible rain before the project was done. Erick came up with a temp fix that addressed my fears and took some extra steps to put it in place. No one made me feel stupid for needing that extra step. They walked me through the completed project which was very helpful. I should also mention that I did get a other quotes. Groundworks was not the lowest quote by a bit. But, they are professional, backed their recommendations with data, and followed up after the project was complete. I recommend this company. Solid organization. read more

We've had a sagging floor in our hallway and my wife found Groundwork's on Facebook so we got an estimate and scheduled the repair. I had a great experience with this company starting with Trevor and Cory. The Foreman Ismael assigned to our project was professional and very knowledgeable. He took the time to explain what was getting installed under our house. He and his coworker always used shoe covers when coming in and out of the house. They also kept a drop cloth next to the opening to the crawl space. Accidents do happen and the plumbing company they use had to be called out to our home. I didn't have to wait too long for the repairman to arrive and fix the issue at hand. Ismael made sure before he left to give me his superintendent's phone number so I have a direct line for any questions or concerns we may have in the future. I highly recommend this company for structural repairs to your foundation or floors. read more

I scheduled BAU to come out and do and inspection and confirmed that the misc cracks were being caused by settling foundation. The inspector, Chance, was outstanding making sure to explain what was happening and how to correct it. Our house needed 16 push piers to stabilize parts of the house that were settling up to 1 3/4". I've never been more stressed out. Enter Luis, Ken, and a few others whose names escape me. They were fantastic completing the work in about a week. It's hard to explain exactly what was done, but I ca. tell you that these guys know what they're doing. BAU also did some concrete work that also turned out great. Im extremely happy with my decision to use BAU/Grounworks and would not hesitate to use them again or refer them to others needing g this type of work. Well done! and thank you! read more

Brandon and his crew were wonderful to work with. We had pretty extensive movement in our foundation, and Brandon was knowledgeable and took the time to carefully explain all of our options and how each would look. He and his crew were communicative and professional. Our biggest fear was that our new kitchen granite counters would crack in the lifting, but Brandon and his crew were extremely mindful of the situation, taking extra care and nothing cracked. Thank you, Brandon! read more

Foundation work is never fun (nor affordable at that). So pricing aside, our foreman Andrew and co-foreman Beto were amazing. Always on time, super nice and professional with my mom, and quick to get the job done with as minimal disturbance as possible. This was a voluntary underpinning on our part, so we'll see what the future brings. But as far as the customer service, the guys onsite were great. Super hard workers. read more

Even though we were not quite ready for the foundation project,I wanted to give a shout out to Johnathan from the Groundworks, Fairfield office.

We had a fantastic experience with Bay Area Underpinning, lifting our foundation four and a half inches of our old 1958 Napa house! After careful review of several contractors, we chose Bay Area Underpinning and so glad we did! The entire process was smooth from the sales engineer estimate to the completion of the job, the communication was outstanding all along from day to day and ourblift was a big job with a full week of labor intensive work. I especially want to thank Foreman Cody Summers, Co-Foreman Ken Hamlin, and Installer Nikolas Klein for their outstanding work and customer service! They are the best and ensured that I was happy with the progress and completely satisfied. I also want to thank Superintendent Kevin Gaeden for his outstanding communication! My wife and I are completely satisfied and happy with the outcome! It was a great choice with great value after the job was complete! We would hire Bay Area Underpinning all over again! Thank you very much for a job well done! read more

Christopher from Groundworks did a thorough job assessing my home for signs of uneven settling or movement and suggesting remedies on the inside and outside. Through the process he explained what he was observing in the floors, walls, and exterior surfaces, and what factors might contribute to the conditions we saw. He used precision level measurements to identify subtle variations in floor / foundation levels and shared practical recommendations based on his findings. Communication was great from start to finish: he texted before arriving, walked me through his process, provided a written report and estimate before leaving, and followed up afterward. Professional, clear, and very easy to work with -- I'd highly recommend Christopher and Groundworks. read more

1. Call Center ***** - they took the call after 6:00 PM and were extremely professional. Guy on the phone (sorry I didn't write is name down), was so kind and emailed confirmation immediately. 2. Pre-Visit Confirmation ***** - Email, text and phone calls to confirm the time and prep me for the visit. Incredible. Nobody is doing this right these days and BAU absolutely has it nailed down. 3. Estimator ***** - I wish I could offer more than 5 stars. Joe Le Bel is the most professional tradesman I've met in a long time. Others are good too, but Joe is the gold standard. He sat with me to ask what I was concerned about and what was important to my family. Who does that???? Oh yeah, Joe did. So comforting. Joe was professional and respectful of our space. Was careful to be conscientious about where he placed his gear, tools and instruments. Super clean going under the house without tracking dirt and debris back into the house. (The inspectors from HomeGuard could definitely take notes on this!) Then, once Joe finished, he sat down with us and talked us through all the different aspects off his inspection. What an extremely positive interaction. I would 100% recommend BAU and Joe. Can't get any better than this. Thanks BAU for a great culture of excellence. Thanks Joe for being such a good human and professional! read more
