EXCELLENT Based on 18 reviews Ali O2024-12-21Trustindex verifies that the original source of the review is Google. I wanted to have an addition done at my house and I contacted Mosaic Build Design in Sterling, VA. Mr. Yuksel and his team have been a great help with designing and obtaining permit. Their professionalism and expertise are commendable. While the design process was going on I had issues with water heater and he sent his plumber and electrician and got that taken care of right away. Saying Thank you will not be enough to express my gratitude towards them. Mr. Yuksel and his team goes above and beyond their call of duty. I highly recommend them for any home renovation and addition work. minoo samuel2024-11-30Trustindex verifies that the original source of the review is Google. Mosaic (Dennis) was responsive and he followed through with everything he said. He gave good design ideas keeping in mind functionality and price. He was flexible with our needs of project delivery timing. We had guests coming, and we needed the project at a point where they could stop for a week, and they did! We truly appreciated his flexibility there. Overall he is a pleasure to work with. The project was completed within the time frame and cost as expected. We would happily use Mosaic services again!
