"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."

"Jose and team did a great job on a French drain project at our home. The whole process from estimate through project completion was done very efficiently and effectively with good communication and follow through. Very happy with the end result and will hire them again to do other projects on my house."

"The company solved our drainage and grading issues in a very timely manner. They are very thorough and provide good communication and customer service."

"Rafael did an excellent job repairing my fence. I will highly recommend him for any project based on how he completed this one so thoroughly. Thank you again for a job well done. It was a pleasure meeting you."

"I couldn't be happier with the concrete work that was done in my backyard. From start to finish, the team was quick, professional, and incredibly efficient. They showed up on time, communicated clearly throughout the process, and completed the project faster than I expected without sacrificing quality. What impressed me most was how they went above and beyond to make sure everything was done right. They paid attention to the details, kept the work area clean, and made sure I was completely satisfied with the final result. The finished concrete looks fantastic and has completely transformed my backyard. I highly recommend this company to anyone looking for reliable, high-quality concrete work. Excellent service, great workmanship, and a team that truly cares about their customers!"

"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."
