"Christopher was very helpful, he guide me through all the process of making a plan for the city. He was very patient with me through the project. Overall I was very satisfied with the project."

"Omid and his team built a brand new bathroom in my home. The work was complicated as the home was just built in 2020. The foundation was concrete as thick as 18 inches with post tension cables running through. Omid laser mapped everything and determined the depth of plumbing through precise calculations. His team worked very carefully excavating through the concrete to then go 6 feet deep and access the main plumbing line and then perform all the work to connect the rest of the new plumbing, required by the new bathroom. Omid also utilized the space to the maximum and the bathroom looked much bigger than I had initially thought. The finishing was splendid with octagonal marble tiles aligned to perfection, additionally Omidâ  s team worked on extending storage spaces under the stairwell to further maximize storage value for us. I would highly recommend Omid. He and his team worked round the clock and even on weekends. I was really impressed by their schedule. I have heard horror stories where contractors leave work in the middle of the project or take up multiple assignments and only spend a few hours a day. But with Omid I was pleasantly surprised by the 8 hour work days and when they were running behind they were coming over weekends as well. Great job done at the end!!"

"Working with David was seamless. He did what he said he was going to do, was on time with his work and the work was exceptional. He needed to work with an engineer to get certain specialized part of my garage to pass with the city but i got approved from the City of Sacramento for my garage rebuild on the first try ! ! I will be working with David in the future and highly recommend him."

"Roberto Sandoval and his company have been doing our landscaping for many years. We’ve always relied on him for honest, reasonably-priced services with excellent care and attention. Absolutely recommend him highly!"

"Andres was awesome! I called for an estimate and he came out the same day. We went over what I wanted and he made suggestions to help reduce the price. The suggestion he made also gave more character to the back yard along with saving money. He started the work the day after the estimate, poured and stamped the concrete, laid artificial turf and decorative rock in 3 day. I am very very happy with the job. His crew worked very hard and all were very nice. I am more than pleased with the experience of working with Andres!!"
