"Posted my request on Saturday, received a call on Sunday, and had a tech on site Monday afternoon. He came knowledgeable and prepared for the job and, once he found a suitable replacement for the pump, had the system up and running in only a couple hours. He bolstered my self-esteem in pointing out the joiner that I couldn't get to budge was cemented in place by the installer. Reasonable price for replacement, as sumps are expensive, and he even rolled my hose back up after we used to prime the pump. Service oriented team!"

"Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!"

"The person performing the service had to make several trips because one of the "new" parts turned out to be faulty. I found both Complete Protection and their local repair contractor to be both very responsive and totally professional at every stage of the repair process."

"The two man crew was hard working and knowledgeable. The repairs have held so far. Both crew and office were easy to work with. There was a disconnect between the office and the crew as to what work was to be done. They exceeded the scope of work, but I was able to negotiate a settlement. They charged a lot for materials. For example, they wanted $1800 for the pump; I found an identical unit for $800. I would use them again, but make sure there is a very clear understanding of what is to done and what it will cost. <br />"

"The contractor removed one tank containing filtering media the added a larger one with a media that was sufficient for the iron content that had to be removed. He further adjusted the system and corrected the water flow and backwash cycle. Other tanks were cleaned along with the flow valve for proper functioning. The contractor was in and out in four hours using two workers that were both polite and competent. Everything was cleaned up and was left in better shape than when they arrived. From the time they put the new system on line our water has been perfect. We are so happy after several contractors worked on our system for 10 years and none of them has gotten it right. <br /> WE RECOMMEND THIS CONTRACTOR TO ANYONE WITH BAD DRINKING WATER!"

"The valves were replaced and a leak in the line running from the house to the pasture faucet was repaired. After all repairs were completed and Neil went to another job, he came back later to test the repair to the pasture pipe before recommending turning on the water to the pasture. I was impressed with his follow through."
