Installation is fairly straight forward, but the mantels and shelves are heavy and cumbersome in length, so it will require a minimum of two people for installation (and in the case of the 8" x 8" x 72", three people is best). It is recommended that you consider employing a contractor for installation for best results if you are installing onto brick or stone where material will need to be removed (commonly called chasing) and the mantel installed into stone/brick.
