Get matched with top excavation pros in Kentfield, CA

"Miguel is responsive and professional. He has a confident grasp of excavation project options."

"I am incredibly pleased with this company. The entire crew were 100% professional. The owner of the company took time to answer my homeowner questions as they came up. He was very patient and thorough. All the men on the job worked incredibly hard and stayed on task throughout the project. They installed the French drain, installed a washout and removed an old deck all in a weekend. I would most certainly recommend them."

"I cannot say enough about how good this experience with John Mountain/Mountain Engineering has been. They said it would be 3 weeks; anti was. The work was painstakingly done, including a French drain behind the wall. And they replaced the plants that were destroyed during the process, which was an unexpected bonus."

"Two large projects. Couldn’t be happier. On time, excellent workmanship, wanting to please but open to making suggestions when asked. Superior design and quality of work. Reasonably priced. Thorough clean up after the job . Owner on site to supervise work. Owner very knowledgeable. Owner returns calls promptly. Neighbors LOVE our fencing and landscape."

"They did an amazing job, and I would hire them again for sure."

"Edgar and his employees were amazing. Their bid was the best. Other guys said they would have to rip up pavement that this crew could do no problem minimally. The guys were so well groomed and polite. Not that that matters but it was an extra bonus. Lovely crew and incredible job in a few days. I will for sure use them again."

"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"

"Outstanding work at a reasonable price."
