"I am a Realtor and was representing Sellers. The Buyers in athe transaction wanted $16,500 for foundation work based on a report from a foundation inspection company. My property inspector and an architect friend felt the report was completely in error. I called Home Advisor and Padir responded. The inspector came out the same day; charged a very reasonable price and delivered a professional 17 page report. We gave that to the Buyers Realtor and settled on a very small credit based on the report from Padir."

"Shilpa did an amazing job designing an addition to a home we bought. It included remodeling an extra framed garage into a master bedroom suite, laundry room and powder room plus adding to its size . The project also included doubling a great room to blend into the house with the new suite as well as opening up the kitchen to this great room and raising the ceiling . The design blends really well and will provide a nice open plan for living and entertaining I was impressed with how well Shilpa understood what we wanted and executed the plans in the time frame promised if not earlier. She also pushed it thru the planning dept. with minimal need for changes. The project is on going and is moving along well Shilpa is always available to answer questions as things progress. The contractor feels she is easy to work with as well. I really enjoyed working with Shilpa and easy her demeanor ."

"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!!"
