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.

Ken showed up today promptly, and when I say promptly, I mean to the second level promptly, at 09:00. He clearly had read all the notes about my unfortunate situation, but asked me to update him with all the work I had done since my initial call. He was forming his plan of action in his head as I briefed him, after I had finished, he went out to his truck, put on his coveralls and went under my house and did a very thorough inspection. I could hear him moving things around under there and every now and then banging on things with his metal probe tool he took with him. He explored every corner of my crawl space, took numerous pictures and had a surprisingly good diagram of my foundation mapped out on graph paper ready to show me when we sat down to go over the results. The results..... He took a deep breath and said, "OK, we got a lot going on here," and proceeded to explain a little about the general layout of my crawl space, which was, let's just say not your typical crawl space, then he showed me his pictures, ("they were much worse than I imagined") and said, "so here is what I would do, if this was my mother's house". That pleased me very much, I said "yes that is exactly how I want you to approach this, I want it done right." I will confess, I am somewhat of a perfectionist, a retired perfectionist, that takes naps during the day, and used to do all my own work on everything, cars, carpentry, welding, etc., etc., you get the idea. I LOVE to buy tools, and by doing things myself, I could justify the expense of any specialized tool I needed to perform the task at hand, then I just self taught myself on how to properly do what ever needed to be done. "If you want the job done right, do it yourself," was how I rolled, until my body decided to start protesting. Ken layed out his plan and I loved every bit of it, because I know, his plan is a good plan, it is the plan I would have come up with myself, I loved this plan. It is proportional to the level of damage, but logical and measured in response. I haven't seen the quote yet, but I know enough to be able to visualize what they are going to have to do to properly fix the damage, and the difficulty level involved. I have no doubt, that when I see the quote, it will be fair, right Ken?

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.

I was worried that the beam supporting the roof was not adequate and that was leading to foundation issues. Most online advice suggested to hire a structural engineer to inspect the foundation, as contractors may blow minor issues out of proportion an suggest unnecessary repairs. The structural engineers quoted me $500 for an inspection and they wanted pictures from a foundation repair contractor anyways, since they wouldn't go into crawl spaces. I was losing sleep thinking about my uneven floors, so I decided to reach out to NorCal Ram Jack for a free estimate. What was there to lose? After filling out their online request form they reached out within a couple of hours and scheduled an appointment the following week with Adam, their Foundation Specialist. Adam showed up early and I was easily able to communicate my concerns to him. He measured the elevation differential throughout my house, asked about details of the removed wall and installed beam, and answered all my concerns. He walked us through his thought process and what signs of concerns we should look for that would warrant a foundation repair. We are lucky that our house currently doesn't have issues of concern, but I wouldn't hesitate to contact Ram Jack again with the peace of mind they gave us.
