"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)."

"Home Advisor does not have the specific category for the work that was performed of replacement of graded retaining wall up my driveway and around a structure. The work utilized excavation, concrete, wood & construction. Cristian, the owner, was the epitomy of professionalism as with every crew member. Firstly, he did not try to sell me on something I did not want, much appreciated. The job was meticulously executed in record time at the price I could pay. This job has been on my bucket list for years... finally completed with a job well done!"

They did an excellent job of installing my new water heater and went over and above in explaining how to take care of it, etc. I will for sure be calling them if any other plumbing issue in the future. I am THE PICKIEST person on the planet and I HIGHLY recommend Doug and his son!"
