*General Contractor

"I interviewed a few people before making my decision using Rok and Iâ m glad I did. I did a complete gut renovation and he basically made my revision come to fruition. Even with the delayed/problems with renovations he always kept me informed. U told me he would always have someone at my house working and that he did. Not like the contractors Iâ ve worked with in the past that say that but then once they get the job.. the â oh someone would be thereâ and no one comes. I had a leak issue and he made it to my house 10 pm to assure it was taken of. Roc is reliable and hard working."
