"Great to work with! Quick response, great communication, knowledgeable, and very happy with his work."

"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!!"

"I wanna recommend them. They are professionals"

"These guys are awesome! From day 1, Andres the M.I.C (man in charge) was very engaging throughout out the process. This was my first time major project to my house since I bought it a few years ago. I recommend anyone who needs concrete or any landscaping work to pick this crew and pick Andres brain for advice when trying to bring your imagination to life. I would ask him what has he's seen that looked great or awful where my lot was at. I appreciate what he shared. It came out better than expected and I have received multiple compliments to this day. The Valley View Landscaping Maintenance Crew kept it 100% professional and kept me informed every step of the way. I will definitely hire these guys again. And again I WILL HIGHLY RECOMMEND THEIR SERVICES IF YOU NEED some landscaping work - Bruce"
