 Trustindex 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.

 Trustindex 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!

 Trustindex verifies that the original source of the review is Google. Mosaics finished a very large scale outdoor deck/patio for my 3.5+m brand new construction.  Dennis the owner is very humble and kind and gave me a very fair price and never raised the price throughout the project.  Most importantly he returned to fix all the minor details that I wanted addressed.  This is my 7th home and worked with many many contractors over the years and he is definitely one of the best!
