I had a really great experience working with RSL Structural Inc. and Ricardo, the owner…read more Ricardo completed our earthquake retrofitting, foundation crack repairs, and all related structural work, and I honestly couldn't be happier with how everything went. Ricardo was easy to communicate with, knowledgeable, and very thorough. He took the time to explain the work, answered my questions, and made the whole process feel much less stressful. He also handled all of the city permit paperwork, which was a huge relief and saved me a lot of time and hassle. The work was done as promised, inspections were scheduled smoothly, and everything passed city inspection without any issues. It gave me a lot of confidence knowing the job was done right and up to code. If you're looking for someone reliable and honest for structural or foundation work, I highly recommend RSL Structural Inc. and Ricardo. I would absolutely work with him again.

Ramon was SUPER communicative and responsive, gave reasonable timeline expectations that he met or exceeded, and provided clear explanations for what he and his crew were doing. Ramon checked in with me at different points in the installation to give me the chance to see the work in progress, point out factors impacting the installation process (e.g., removal of tree roots), and did a thorough walkthrough afterwards and provided me with the post-work elevations for documentation. Wore shoe coverings in the house and laid out work paper to avoid tracking dust/dirt. Ramon also pointed out that they did not end up needing to do some work that was in the original estimate and so put in a change order to reduce my invoice / get a refund. OVERALL: Glad this team was working on my house. Communicative, responsive, clear, honest.

We contracted with Groundworks to accomplish a lift and stabilize our house, which is between 4"…read moreand 51/2 out of level. The job was described in detail. We were told that the downstairs room, with a concrete floor, would have small holes that may need to be puttied. They did not say, at that time, that the inside stairs would need to be pulled out. After the job started, they showed me how there were existing piers that they would need to cut off at the top to accomplish the lift. They said that those original piers would still help with the horizontal integrity and their piers would stabilize the vertical movement. That they would re-attach the original piers after the lift. They took out the concrete exterior steps and estimated $12,000 to rebuild them after the lift, a change order. They asked if it was ok to put the back wall piers inside of the wall, because they were worried about the dirt collapsing in on them. The holes are big, roughly 2' (or more) in diameter. There are at least 5 big holes in the downstairs room, and also some, at least 3, on the downhill outside. They also pulled out some asphalt in the driveway, at our request. Then I got the call that they ran into too much concrete from the original foundation and could not accomplish the job. At our request, they worked one more day. I've asked for a plan going forward. They didn't even try to convince us to be happy with just stabilizing. I then told them that I'd like them to just put it back, as close to how they found it as possible. For 2 weeks, I've been waiting for some kind of proposal of what to do going forward. I do want to accomplish the lift, have waited 30 years to do this. At this point, we just want them to clean up the job side, fill up the holes in the floor and outside, possibly rebuild the back steps. We are extremely disappointed. Every day I cannot rent this space is a loss. At this point, the communication could not be worse. We have called and texted, have gotten almost no response.

We had a few folks out to assess the problem and Steve from Foundation Repair of CA was much clearer in communicating what the issue was than any of the others. He also offered us different options, giving us a straightforward assessment of the benefits and drawbacks of the different options. In the end, we went with drainage, encapsulation, and sump pump installation. Ernesto and his team (David, Juan, and Kelvin) came out for the installation and we were so impressed with the efficiency and quality of their work. Overall we're really happy we went with these guys, and are feeling so relieved that we don't have to worry about heavy rains anymore!

Foundation Repair of CA (FRC) is the most disreputable, dishonest company I've ever encountered. I…read morehired them because I didn't want to hire the lowest bidder for a change, and I regret it. I wouldn't sign the contract when told I'd have to do my own masonry repair until sales agent Jesse Marquez showed me FRC corporate material that indicated the brick facade would be removed with a masonry saw, in an approximate 2x2' square. That was false and deceptive advertising. This is what they did to my house. No masonry saw was used, only impact drills, which act as small jackhammers. FRC significantly damaged the entire brick facade, adjacent areas showed extensive cracking, entire areas had the brick facade knocked completely off the house, and the wall foundation was separated from the brick wall entirely. I told the work crew, headed by Luis, to stop using impact wrenches on the bricks immediately, then told them TWICE. Not only did they not stop, despite direct STOP work orders, they then took all of the bricks they'd destroyed, which legally is theft, called conveyance. Jesse Marquez explained that the bricks were so old they'd shattered. Luis returned the bricks after Jesse Marquez called, ignoring my several phone calls and texts. Jesse texted that the bricks were so old they'd shattered. Luis returned them, none were shattered, all were broken by the impact drills. Luis confirmed, texting that the bricks were "broken". They took the bricks to hide the damage. The day FRC received my Contractor's State Licensing Board complaint, FRC messaged that someone would come to assess the damage for repairs, and FRC would repair the masonry they'd destroyed. They first sent Robert Pagan, who acknowledged both that there were no masonry saw marks, and that the damage was excessive. According to FRC, Jesse stated Robert hadn't said this. It wasn't until I pointed out he'd said it while standing in front of a Ring camera did that lie die. FRC then sent Troy Knight, who acknowledged the same, and stated he was there to help, and would see that the masonry was repaired and more. I have several texts, voicemails and emails from FRC stating they will complete the job. They never did. FRC employee Mike Crites was sent to perform the repairs. He returned the following week with the wrong sized bricks in the wrong color, and proceeded to do more damage. This is the work that they did. FRC employee Mike Crites initially stated that he had retired as a mason, he later revised that statement, saying he'd only worked with pavers and concrete. The work performed was so substandard, FRC sent Jovincio, who was the only honest person in my entire dealings with FRC. Jovencio said he wasn't a mason, but had "some training". Jovencio replaced the work done by Mike Crites. This is Mike's effort, and Jovincio's replacement work. The work performed is clearly substandard and unacceptable. FRC acknowledged the workers sent lacked the skills, training and necessary certifications to perform masonry repairs. When I requested that FRC send a mason, and included photos of the work, FRC responded that they'd done me a favor; the workers sent were a courtesy. The very clause they'd ignored (and invalidated) by removing the bricks was cited. That they would do no more, leaving me with the bill for their damage. This is what they left. I obtained a second quote to repair the deficient masonry 'work' FRC workers had done - without a REQUIRED permit, with no mortar pins, odd-sized and broken bricks mortared in randomly, mortar lines that range from non-existent to more than an inch. Crites' also removed the brick facade foundation in several sections, replacing it with sloppy concrete. This is a code-violating 'repair' that is neither plumb nor square. The legitimate mason company from whom I obtained a repair quote updated the quote, which has nearly doubled BECAUSE of the 'repairs' performed by the unqualified FRC employees. FRC called this doing me a favor, saying the inept crew was sent as a 'courtesy'. This is not doing me a favor, this is not a courtesy, this is at best fraud. After signing the contract (under false pretenses), Jesse insisted I needed an additional pier ($3,155) because piers can no longer be placed under a window. A pier was placed under the window. Two other piers were not placed according to the county approved structural engineering ($1,850) diagram. Half the piers were installed in the wrong places, apparently according to Luis' whims. Yesterday Groundworks gave an estimate on properly placing those piers. That's how I learned that the improperly placed piers had lifted a joist completely off its foundation supports. This, too, will require additional expense to correct, before it damages my house - literally to the roof. I should have stuck with Groundworks. This is your cautionary tale - no one who values integrity, ESPECIALLY senior women, shouldn't hire FRC.

Jonathan is an absolute gem. He is so down to earth, smart, kind, and you can tell he cares about…read morewhat he is doing and about the customers. He has over 19 years of experience, started from one of the first companies to do this well out in the bay and then branched out to his own company, where it's clear he wants to commit to doing a good job for the customers versus just making a large profit. We got a quote from another company who was running a ton of ads and it was very clear after meeting and talking to Jonathan that the other company was in it for the money and the biggest job possible. Jonathan came in, sat down, explained ALL the issues. Drew pictures for us to understand better since it was clear that we were over our heads(esp since we spoke with the other company that made it seem like our house was a danger to be living in) then he continued to explain all of the structural components of our house and how it helps with the safety/etc(NONE of this was done by the other well known/IG ad pushing company). He took his time, went over different options, gave us rough estimates for both. Suggested and gave a list of people he suggested for soil reports(Within less than an hour of meeting us). Broke down costs and said YOU SHOULD NOT HAVE YO PAY MORE THAN THIS and laughed as I added extra for what if's. He was such a lovely person and his quote was WAY less than the other company who only gave us one very expensive option and then didn't even bother to send a full estimate (groundworks) I immediately wanted to work with him right after and plan to. Highly suggest him for any of your foundation needs. Save yourself time, no need to get other quotes from other companies and just go with him:)

Jay performed a foundation inspection and identified multiple areas of inadequate work in the floor beams and footers. This required patient assessment of what appeared to have been done compared to what the structural engineers had designed. He then creatively performed work to bring the supportive structures to what the original plan had called for but somehow my prior contractor missed or took shortcuts. Jay also performed earthquake retrofit and worked to get the subsequent inspection smoothly signed off. In the years since Jay performed his excellent work, we have noticed no more seasonal shifts in the problematic part of the home. Jay was honest, ethical, and transparent with his work and we are very satisfied with his work. I owe him an apology for this very late review.
