"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."

"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."

"Campbell services provided me timely excavation of driveway. His crew were professional and courteous. I was pleased with the time they took in making sure the mess was cleaned to my satisfaction along with taking extra care to preserve the existing landscape. I only wish other companies would adopt that type of work ethic."

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

"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!"

"David kept the work on schedule and budget. Installed fence and service gate. In addition David's crew worked on repairing a 700 sq ft deck."

"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."

"Home Advisor does not have the specific category for the work that was performed of replacement of graded retaining wall up my driveway and around a structure. The work utilized excavation, concrete, wood & construction. Cristian, the owner, was the epitomy of professionalism as with every crew member. Firstly, he did not try to sell me on something I did not want, much appreciated. The job was meticulously executed in record time at the price I could pay. This job has been on my bucket list for years... finally completed with a job well done!"

"Finding a plumber who is there to solve the issue and not try to redo your whole bathroom is hard to find. Everyone wants to cut and replace but New Era Plumbing took the time to diagnose and fix what was needed. Efficient. Cost effective. Has the skills, knowledge, and confidence to do it in one morning. I feel like lots of plumbers wanted to hedge on what they could deliver, especially since they are turning off your water. I’m very grateful to finally find a skilled professional."
