"Several months ago, I noticed that doors in my house were no longer closing and latching. Specifically, my front door no longer locked completely. Once I got it fully locked I could no longer open my front door anymore, so I knew I had foundation issues. I called Bay Area Underpinning to come look at my foundation and do some measurements. We discovered that my front living room was sinking approximately one and a half to 2 inches. The crew, Lance Sladek, Jake Hall, and Eddie Shaw, crawled under my house and dug 30 to 40 foot holes in the ground to install piers that would lift my foundation. These gentlemen worked in very cramped dirty conditions in 90-100° weather. I was extremely happy with their work and their dedication to doing the job correctly. My after the foundation lift, my front door as well as several other doors in my home were able to close and latch again."

"I contacted M&J Prime Builders on a Sunday morning via an urgent request on Angi (Angie's List) to repair a leak in our backyard irrigation system. Javier contacted us immediately and arrived at our home in Concord with his business partner, Marcos, within 90 minutes. They were very attentive, professional, and accommodating, especially for our unexpected Sunday morning emergency. They not only repaired the leak but also addressed another issue that had arisen with our shutoff valve. Their estimate was very reasonable and accurate, and their work is top-notch. Javier is both a licensed contractor and a civil engineer. As a result, they offer a wide range of home improvement projects. I will be using their services again and highly recommend M&J Prime Builders"

"He did a great job! Everything was fantastic. He did it on time, he did exactly what I asked him to do. The finish on the concrete was really beautiful on the driveway. He cleaned up well. They did everything on schedule. All of the slabs they did are great and there are no cracks. All of his crew are very easy to work with, they were very respectful and professional. I would highly recommend Galletti Concrete!"
