Erin V.

Talk and mercury team were so nice, professional , and honest ! They re-did my entire bathroom and I’m super happy with the final product ! I will hire them for sure next time !

Sean G.

Mercury design and build supplied me with full home interior design. Their product started with a basic 3d. Once I picked the materials they rendered the project and built it in a way where I can "walk" inside my new home like it was already done. It's hard to explain how detailed and impressive this is, I would recommend mercury d&b to anyone asking.

Steve M.

We are very satisfied and happy clients. Mercury is professional in all aspects. They are honest, hardworking & kind which is rare nowadays. Their goal is for the clients (which they treat as friends) to be happy and content. I already recommended them to my friends, family and co workers. Five stars rating.
