    so I called foundation specialists to check my foundation amd floors sinking and out of the 5 only 2 called back and set appointments for their assessments. Only 1 showed up and provided an estimate 10 days later for a very high price with no explanation on the work they will be doing. I came across Foundation Builders and set up an appointment for the next day. Their inspector Daniel came by on time and performed a thorough assessment and provided different solutions with clear explanation of the work, differences in options and prices on the spot. This professionalism surpassed my expectations, and their price was much better and I signed the contract on the spot!! A week later their crew came in and started lifting and leveling my house while I still lived inside. They were very clean and tidy in their work and finished within the 10 days as they promised. My floors are now all level and solid and I couldn't be more excited about walking on flat floors in my home. I would recommend Foundation Builders to anyone looking to repair or level their house.

    Needed an earthquake retrofit for my home. I have a raised foundation and my insurance is with CEA. As CEA has threatened me with a letter saying my insurance may be cancelled without a retrofit I decided to find a contractor and have it done. I found Foundation Builders. They gave me a competitive contract for the work. It was completed in one day and the city inspector said they did a very nice job. CEA sent me a form to fill out to prove I had the work done and Foundation Builders filled out the form within a few hours. Thank You. I highly recommend Foundation Builders.

    Minor but numerous cracks had appeared on the interior drywall over the past few years and there was no drainage away from the foundation. My initial request was for an inspection of the crawlspace foundation and foundation waterproofing. Original workscope was just for french drains for each downspout and waterproofing on one section of the foundation, with the costly option of helical piers where the foundation had sunk. As they excavated the problem section, it was found that the footing under the foundation was non-existent (house is from the '40s), so I had to spring for the helical pier system as the problem would only get worse. I may have been very lucky with the scheduling, materials and logistics, resulting in some savings as things unfolded very quickly. In fact, they were able to fit my job in less than a week of my initial Yelp search. They came in with a large crew to get things done very efficiently. Project managers, foreman and crew were very knowledgeable and great to work with. A few other contractors I contacted seemed just fine, but didn't seem to have the breadth to fully address my foundation issues.

    A view of the under-pin holes and rebar.

    I had a crack in my slab foundation that was leading to several problems. Although it wasn't a serious structural issue, it was very discouraging to remodel a bathroom and then have cracked tiles a year later, or to watch large cracks in my walls and ceiling grow over the years. I had put off any further renovations because I was so discouraged and took forever to actually bite the bullet on foundation repair because so many foundation companies are out to charge insane amount of money selling unnecessary and expensive solutions. I hired my own unbiased engineer to tell me exactly what needed to be done, then I hired my own people to do the work the engineer detailed. The people I went with were Foundation Builders and Jose and his crew did an incredible job. It's hard to believe that they could jackhammer up half a living room and dining room worth of slab without making any mess in the rest of the house but they did it! They underpinned, re-barred, and poured a level slab tied into the existing slab and fixed some drainage issues and I couldn't be happier. Since they finished their work I've been getting to all the renovations I was too discouraged to do and have been enjoying my nice, solid foundation.

    Foundation problem is never fun. It's massive and you don't get the benefit of enjoying a new anything like in remodeling. But if you encounter a foundation problem you better deal with itZ and if you do, foundation builder is my recommendation! They been professional from the very first contact, always responsive and responsible. I had to level my kitchen, they were quick and clean and gave me a fair price. All in all they did a great job and turned an unpleasant necessity to a good experience.

    Helical piers installed to stabilize the house

    My house had foundation issues that were not resolved by another company we had used about 5 years ago so we tried this company instead. They were prompt, reasonable in price and much more dependable. I appreciated how quickly they came out and resolved the issue. I am hoping there is no more significant movement in our house with the helical piers they've installed. I would recommend them !

    This is what they did under my house hood job

    Having just hired Eldar and his team on a 3-week project, I absolutely recommend The Foundation &…read moreDrainage Repair without reservation. This was the best experience I've ever had working with a contractor, and I've worked with some really excellent ones both in LA and the Bay Area, as well as some true scumbags who amounted to fraudsters (hence my anxiety surrounding this project and my meticulous due diligence). Eldar is honest, experienced, and so very kind. He knows what he's talking about, he explains the issues thoroughly, his solutions are logical, and his prices are reasonable. Women, especially, take note: he won't talk down to you, and he won't bullsh*t you or waste your time. He stays positive and friendly, even when new challenges like huge, invasive roots up against and under the foundation reveal themselves as the project progresses. He communicates clearly, sets realistic expectations, and provides comprehensive progress updates at the beginning and end of each day, and sometimes more if urgent matters come up. He listens to clients' needs and expectations, and is very good at working with anxious customers. His team is professional, punctual, super friendly, and incredibly hardworking. They went above and beyond every single day, kept the worksite clean and tidy, and ultimately left my yard much cleaner than it was when they started. So, to sum up my experience: These guys are fantastic. Don't wait. Don't hesitate. You'll be in great hands. Now, if you want all the dirty details of my cracked slab and water intrusion saga: I had several different foundation/structural companies come out (yes, even the usual suspects in sponsored search results) and look at my foundation over the past few years, and I got vastly different suggestions on what I should do to solve my problem, with a range of very high prices. I was overwhelmed because none of the solutions seemed right to me, and I was worried some would actually end up causing other problems down the road because they went overboard on foundation support, but didn't address drainage. After my first meeting with Eldar, it was clear to me his solution would be the most effective for my problem, which was 99% caused by a lack of drainage around my property. The rest of the problem was caused by a very shallow free-pour foundation on one side of the house (1950s construction), which Eldar and his team uncovered during the excavation process, and supported by making some very solid, high-quality footing extensions, which they waterproofed. Expansive clay soil and a slope behind my house also factored in. I had so much anxiety about hiring a contractor who would take the wrong approach along with all my money that I basically sat on this problem for four years. Bad idea, I know. I'll spare you the details of my insanity every time it rained, but let's just say lots of stress, dozens of shop towels and multiple Quick Dam flood barriers were involved. I was seriously losing my mind with every new crack in my slab and walls. Now that Eldar and his team are done installing deep french drains, waterproofing, footing extensions and a sump pump, I feel such a sense of relief. I'm confident that I'm going to survive this year's anticipated El Niño storms while maintaining my sanity, and I feel so lucky I found The Foundation & Drainage Repair when I did. I'll update and post videos of my beautiful new sump pump in action when the rains come.

    LICENSE SUSPENDED: Avoid This Contractor: Failed to Comply with CSLB Arbitration Award…read more I am updating this review to warn other homeowners to check the California Contractors State License Board (CSLB) records before hiring LA Structural. As of March 2026, their license has been officially suspended due to their failure to comply with a legally binding arbitration award. On October 22, 2024, LA Structural requested and collected full payment for the second contract (permit acquisition for all work listed in the first contract) before any permit-related work began. Note: This is a violation. Despite full payment on November 26, 2024, none of the required permit finalizations occurred as promised, and the contractor stopped all permit-related work. Required tasks--such as coordinating inspections, correcting the soil compaction report rejected by LADBS, and managing final permit approvals--were not performed by LA Structural and were left entirely to me. I spent the following five months working directly with LADBS and city inspectors to complete these tasks. During those five months, I identified two defective areas of work. First, the soil compaction report was rejected due to LA Structural's circumvention of requirements. LA Structural hired a deputy instead of a third-party geotechnical engineer, bypassing the grading inspector's requirement and misleading me as the client after charging an additional fee for this engineer and report in November 2024. Consequently, in February 2025, Inspector Bonvouloir officially rejected the report. Later, Clark Inspections--the subcontractor hired by LA Structural--emailed me stating that LA Structural planned to use their in-house engineer to revise the soil compaction report, again attempting to bypass the requirement. I ultimately had to redo the soil compaction report through a licensed geotechnical engineer and resubmit it, after which it passed the city's review. The second defective work involved the drainage pipe and was documented in the CSLB investigation report. After 13 months of CSLB mediation, investigation, and site inspection, a mandatory arbitration hearing took place on January 22, 2026. The arbitrator ruled in my favor and ordered payment within 30 days. LA Structural failed to comply, resulting in their current license suspension. Notably, prior to the issuance of the stipulated arbitration award letter, the contractor repeatedly attempted to have me sign his own private settlement agreement--non-CSLB documents with terms that went beyond what had been agreed upon at the hearing. Don't sign it! I later learned that this is a common tactic contractors use to remove CSLB from the matter. Per CSLB instruction, I filed a claim with their bond company, Jet Insurance, to recover the awarded payment. Despite their written commitment on February 11, 2026, to issue payment if the contractor failed to meet the CSLB deadline, Jet Insurance instead extended the deadline to March 27, 2026, stating that "the contractor intends to make payment by this week." LA Structural failed to meet this extended deadline as well. On March 30, 2026, I received an email from Jet Insurance stating, "Attached is the Final Release and Assignment of Claim agreement, relating to the claim...In order to issue payment for this claim, Jet Insurance Company requires the attached agreement to be reviewed, physically signed and all pages returned." It has taken 16 months to recover my funds for their abandoned and defective work since their collection of full payment. Based on my understanding, when a bond company pays out a claim, the contractor's license remains suspended until specific legal and financial requirements are met for reinstatement.
