"The Groundworks folks (formerly Bay Area Underpinning) applied their foundation-underpinning technology and expertise to extend to bedrock, level, square up the foundation for an extensive house remodel. I was most impressed by the young man onsite supervisor, Josh who answered all my work done, how and why questions. I wish this info was provided up front by the estimator. (My design-build remodel contractor referred this company). "

"All around good experience"

"Do not contact this company, and do not be misled by their professional appearance. The quality of their work is poor, and their follow-up warranty service is virtually nonexistent. I had major foundation repair work completed by EagleLift (now part of Groundworks) in 2023. The project included underpinning the perimeter foundation with more than 20 push piers and replacing approximately 50 crawl-space posts. Problems began on day one. Even after this costly repair, several areas of the house remained unlevel. EagleLift attempted to correct the issue but was unable to do so. The situation worsened after EagleLift became part of Groundworks. Groundworks has failed to respond to my service requests, despite my 25-year warranty being part of the contract. As a result, I had to spend additional time and money to completely replace the portion of the foundation where the issues were most severe. Other areas that were repaired by Groundworks still have unresolved problems, and I have receiv"

"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."

"The gentlemen from Davey's were complete professionals, courteous, and a pleasure to work with. They were very careful in how they handled the trees and my property and left the work site cleaner than when they came. The price came in higher than another estimate, but I think they were worth it. I had three previous tree services that did not do anywhere near as well, left the site messy, left wood behind, and they were not much cheaper. Davey's is the best of the 4 by far."

"My wife and I worked with Joe to renovate our home in the South Bay. We basically tore everything down to the studs and did some reconfiguring of the interior, as well as redoing all plumbing and electrical. With Joe and his team, we transformed a home that hasn’t been renovated since the 60’s to the home of our dreams. We were referred to Joe by a trusted friend, and after a phone call with an overview of what our plans were, we met Joe in person at our home for an initial walkthrough. Both my wife and I were impressed with how thorough he was with details regarding the renovation; it was immediately obvious he was a master of his craft, with a vast amount of experience and knowledge in construction. More importantly, he’s down to earth and honest; his transparency was very much appreciated. Joe and his crew take pride in their work. He’d go above and beyond by suggesting certain looks or practical modifications to our original request; it often felt like he was renovating for himself! For the project, he provided a clearly marked timeline and walked us through all the options for both finished and unfinished materials. His encyclopedic knowledge of stores in the Bay Area saved us a lot of money, and we got exactly what we wanted to build our home with! Home renovation is never a easily forecasted task; there are many surprises or issues that come up. With Joe, we knew we were in good hands. When a challenge did come up, he made sure to explain the options to us and address it immediately. Communication is key in this process, and Joe excels at it - he’s very responsive by phone and text. His crew is polite and also share Joe’s willingness to educate and explain the process. All in all, we felt that Joe became a family friend in the construction business and have recommended him to multiple friends and family. If you are looking for top quality work, reasonable pricing, and a trustworthy expert, look no further than Joe Arielli and his team!"
