"Very honest engineer. He performed a mandatory seismic inspection that was required for the city of Hayward. There was no foundation issue whatsoever. Before Mr Padir did the inspection I had a retrofit company look at my building and they told me it would cost $58k to fix the problem and I almost fell for it. It turns out that one joist was rotten from a sewer leak that was repaired. It is hard to find honest people these days. I am so glad it is only a cosmetic fix and a sister joist installed next to it to relieve the pressure on the building. Thank you once again Mr. Padir. Excellent job and quick turnaround."

"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!!"
