Great experience for Earthquake Brace Bolt (EBB) process! Daniel & Fernando were very knowledgeable about the process. They did a great job of preparing everything for the EBB app and the job was completed efficiently and effectively. Great communication and updates throughout the process. Thanks!

Working with Sinai Construction has been beyond an amazing experience. They respond timely, they are professional and personable too. They started work immediately, taking photos, getting permits and loading everything into the FEMA portal. Immediately, they were approved and started work. They kept all their equipment neat and out of the way during the 3 days of actual work. The employees are very polite, professional and everyone wears uniforms with the Sinai logo which is a plus for me. I have already recommended them to my neighbors.
