"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."

"Water line was replaced by plumbing company. Servepro came promptly at the agreed time. I had cleaned up a lot but water was still coming up from under linoleum. I told the man where it was still a problem and he set up three noisy blowers without wiping up remaining puddles first. He told me he would return between ten and eleven next day. When he didn't I phoned the office and they said it wasn't scheduled but they let me shut off the noisy blowers. After several calls they came about 2PM. I hate to think what my electricity bill will be. They billed my insurance company since I had a claim #."
