"Nick did a terrific job removing the entire front yard carefully. He shoveled the areas he could not reach with his Bobcat, removed tough roots, kept me informed about potential problems, and spread 8 cubic yards of mulch and gravel efficiently. Isaac (Ike), the owner, was very professional and gave me a good price, and even discounted it when they had to come a day late. The work took three hours and Nick left the front clean and swept. Much appreciated!"

"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."

"The work was great, they have the technology to find the issue quickly and they are very knowledgeable. Communication was great at front, we discussed any additional services needed in advance and went over the process in general. The excavation, repair, and finishes were very clean. New Era Rooter & Plumbing are very professionals. I will definitely recommend this company and call them again."

"Marcos and Juliano were great to work with. Their crew worked hard and finished the project on time with excellent quality. We were really pleased with the end result."

"He was available by phone, and was flexible in scheduling meetings which is great. He was professional, and seemed quite knowledgable. In the end, I didn't use Nato's services because his quote was twice as much as the other contractor I was considering. Perhaps his prices may be more competitive in other services he offers. Either way, working with this company was a pleasant experience."

"They did a good job, and we were pleased."

"Very professional and the work performed was at high standard & transparent. I will definitely refer Miguels plumbing , electrical and maintenance to friends and family. Thanks again."

"Alfredo contacted me very quickly and I explained our issue. He agreed to come by the same day. He assessed the problem and gave me a detailed explanation of the issue and how to fix it. This included advising me that the repair could be problematic since the pipe was galvanized steel. I appreciated his approach to keep the repair simple and to address any issues as they came up. His estimate was very reasonable and the repair was successful. There was a small leak that started on a separate section which Alfredo came back and fixed as part of the original bid price. He was efficient and responded to all of my questions. That was very much appreciated!"
