Grading & Excavating
"Humberto is a very creative problem solver! Personable and definitely interested in customer satisfaction, so spends time understanding the full scope of the problem. The problem was the subterranean north wall of the sanctuary of First Presbyterian Church in Vallejo that was far from being waterproof, especially with the rains last winter. Castaneda dug out the soil next to the wall, pressure washed it and applied two coats of DryLok and then a layer of Henryâ s waterproofing. Then Humberto installed a French drain and then a big pipe to route the water off of five downspouts. To get the correct drainage slope, more excavating needed to be done than anticipated. Removed five landscaped trees and lots of concrete that was in the way of the drains which were to be routed under city sidewalks."

"Unquestionably I would recommend him for hire and here's why. Mario designed the system customized specifically for our home, 2 story, 5 bedrooms. He laid out the job on paper and showed us the BOM list (Bill Of Materials), so there was no surprises in cost. He showed up early to work and gave an estimate of time to completion. He is extremely knowledgeable and very communicative to my wife and I concerning any complications found underground (we live in the mountains). He performed as promised and completed our project on time and on budget. He gave us suggestions on maintenance and how to prolong the life of our system. He is a very professional contractor and was patient with our many questions, and great person to work with."

"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."
