John Giuffre did the initial inspection and elevation survey and put together the proposal. He took the time to explain what the readings meant and what the piers would and wouldn't do. I really appreciated his honesty and support. The pricing was competitive. The install crew -- Angel, Jonathan, and Diego -- was the highlight. On time both days, explained each step, and answered every question I had. The site was left clean, and the excavations were backfilled neatly. For a job that involves digging under your foundation, it was about as smooth as I could have hoped for.

He was very easy to communicate with and provided a thorough inspection along with a cost breakdown. TJ and his team arrived to install beam to add more support to living room floor area.

Throughout the process, TJ kept me informed and made sure I understood what was happening every step of the way. TJ and his crew worked carefully, professionally, and thoughtfully to ensure the project was completed without causing damage to our home. I truly appreciate the care, attention to detail, and professionalism TJ and his team put into the entire job. I would highly recommend Groundworks!

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.

I contacted multiple companies specifying that I was looking for a "no job too small" contractor to replace the failed concrete patch. The contractor for the first company I contacted (Napa Valley Concrete) requested pictures, which I sent, and set up an appointment to come look at the patch to provide an estimate. That was the last I heard from him. He failed to show up at the appointed time, and neither called nor texted me again. So, back to the drawing board. I next contacted Connor and Sons via their web site. Paul Connor responded within one business day. He showed up at the appointed time. When I thanked him for doing so, he said "That's our job, right?" :-) I related the all-too-common story to him of the first no-show contractor. Connor and Sons was reliable and professional through the whole process. Paul was communicative when personal circumstances delayed the work. They ended up starting the work on a weekend in order to fit us in between their larger jobs and bad weather. In the end, the concrete itself and its replacement was harder than Connor had anticipated. To be honest, I think they may have lost money on our little job. But Paul honored his estimate despite this. I can't say enough about how good my experience with Connor and Sons was. When our budget allows for our larger jobs, I'm absolutely going to contact them again, and will look for ways to give them more business. Thank you Paul, P.J., Mike, and Dane!

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:)
