Mosaic was billed as 5 star organization promising excellent service and professionalism. The result was far from that. The project was supposed to take 5 to 6 months and it took 11 months. Our chief project manager quit a few months into the job. His underling project manager was so poor that we asked for someone else. We wish we had him from the start. The trades were supposed to be top notch. They were just okay and tried to hype prices overbilling us for things that they did not do. I wish I had used my own plumber, HVAC and electrician. Mistakes were made all along the way and the trades and Mosaic blamed us. The cabinetry firm was fantastic as were the carpenters. Painters were exceptional. The resulting work is beautiful but the journey was difficult and frustrating.

Repalced our double front doors and side door. They helped us pick out doors that would compliment the house, the job was done on time and looks great.

What Mosaic Construction LLC is registered to do
