Get matched with top excavation pros in Richmond, CA

"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."

"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."

"Met with Craig to review the project and agree on a price. Set up a time for the work to be performed. Craig’s team was on the job on time and actually completed it a day early. The workers were fantastic and went the extra mile. I would highly recommend Craig Campbell services."

"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."

"Gio and the entire Ultra Construction Group team are amazing. They showed up on time and were incredibly organized and their attention to detail made the project even better then I imagined. I would highly recommend this company for any concrete project big or small."

"This was basically a demolition project. I had to have a 75 year old concrete circular retaining wall buried in the center of my asphalt driveway that had to be removed so that we could plant an oak tree. The wall was approximately 25 feet in circumference, 4 feet high and the concrete at least 3 inches thick. The bottom foot and half of the wall was covered with earth that had to be dug out by hand. Jose accomplished this extremely difficult job in a day and a half working right along side his helpers. He was able break up and haul away the concrete and did a great job cleaning up the site. He is courteous, professional and his rates are extremely fair. I would definitely recommend him for any job."

"They were great. They did everything and more."

"We bought a 'fixer-upper' and of all the contractors (and we have worked with A LOT on this house) he is the top. He is prompt, he always follows through, his team works hard and gets the job done fast and well. If there are any concerns he comes out personally and takes care of them immediately. He is flexible and thinks on his feet. His pricing is very reasonable. There wasn't a thing that we didn't like about working with Nato and team. He is our official go to guy for landscaping and other projects. We trust Nato, his work and recommendations to us We would definitely recommend him to our friends. My husband found him on Angie's list and it was one of the best finds we have had in the 3 years we owned the house."
