"We hired Groundworks CA (fka Bay Area Underpinning) for what we understood was a full foundation repair. We paid $42K. They only worked on the rear and never informed us that the front wasn’t included. Months later, while selling our home, a third-party engineer found $189K in unaddressed issues at the front. We were blindsided, lost our buyer, and suffered major financial and emotional stress. Groundworks later admitted they hadn’t measured the front. Their rushed “final inspection” months later felt reactive, not professional. When asked for a partial refund, they refused. We feel misled and abandoned. Avoid."

"They recommended a good solution for the occasional shallow flooding in the garage (installing a sump pump) They started soon after we submitted the request and they did a good job. Most importantly, the pump kept the garage dry through our seemingly endless rains this winter. There are 2 reasons I rate the job with 4 stars rather than 5. (1) The job did not pass the city’s inspection and a critical connection had to be reconfigured (after which it passed) and (2) there was some weirdness around payment on the last day of the actual work (before the inspection) in which the crew seemed unwilling to leave without a check and then were slowly driving around the neighborhood afterwards. When I brought this up with my contact at the company, he denied that the van was theirs (which it definitely was) and didn’t really explain or defuse the bad feeling this created. But … they did a good job and in this day and age that’s really important and can’t be taken for granted. I recommend this company with the suggestion that paperwork, permitting, terms of payment etc should be clearly settled in advance."
