"Marco is amazing! He went above and beyond to make our home look amazing. He's a genuine guy and fixed things in my home that he noticed needed repairs. He didn't have to, but he did it out of the generosity of his heart. I would highly recommend Marco and will hire him every time I need a repair!"

"Still in process, but so far they have been excellent. We have run into a snag with the job the flooring company (it was NOT done by JB Custom Finish .. Now I wish I had used them) and JB has, and is, doing everything they can to help us through this."

They were very punctual, hard working, and cleaned up after each day. The kept the dust down to a minimum to the rest of the house. I can highly recommend Oshri Construction for anyone's next project."
