Get matched with top excavation pros in Castro Valley, CA

"Ike was great from start to finish. He came quickly to give an estimate and started promptly. He did a great job at everything the job required. He finished on time and cleaned up well. The job was complex and he triple checked each item to ensure it was exactly what we wanted. Several things were more difficult than expected but he still got it done on time. He excavated, created and graded a 100+ft ledge perfectly. I would recommend Isaac Nathaniel to anyone."

"Giovani and Dell of Ultra Construction were great to work with and they responded quickly and efficiently to our contractor inquiry. They came out the next day and provided a fair and reasonable estimate. Dell and his crew, including Julian came out and had the concrete walkway and stairs installed in just one day. It looks great and we couldn’t be happier with the results. Their prep work and cleanup were outstanding. Would highly recommend this company for any concrete construction work"

"The work was great, they have the technology to find the issue quickly and they are very knowledgeable. Communication was great at front, we discussed any additional services needed in advance and went over the process in general. The excavation, repair, and finishes were very clean. New Era Rooter & Plumbing are very professionals. I will definitely recommend this company and call them again."

"Marcos and Juliano were great to work with. Their crew worked hard and finished the project on time with excellent quality. We were really pleased with the end result."

"He was available by phone, and was flexible in scheduling meetings which is great. He was professional, and seemed quite knowledgable. In the end, I didn't use Nato's services because his quote was twice as much as the other contractor I was considering. Perhaps his prices may be more competitive in other services he offers. Either way, working with this company was a pleasant experience."

"They did a good job, and we were pleased."

"Miguel completely re-configured our plumbing under the house a few years ago and we have never had issues again. He diagnosed the issue accurately and was able to complete the job quickly and at the highest level of quality. His knowledge of virtually all mechanical and structural aspects of renovation/repair are second to none. I would recommend him without hesitation to anyone and with highest confidence."

"Alfredo contacted me very quickly and I explained our issue. He agreed to come by the same day. He assessed the problem and gave me a detailed explanation of the issue and how to fix it. This included advising me that the repair could be problematic since the pipe was galvanized steel. I appreciated his approach to keep the repair simple and to address any issues as they came up. His estimate was very reasonable and the repair was successful. There was a small leak that started on a separate section which Alfredo came back and fixed as part of the original bid price. He was efficient and responded to all of my questions. That was very much appreciated!"
