If I could give negative stars, I would. Scott McMahon is an absolute scam. Says he is experienced in all areas of construction/remodeling, but it's a complete lie. His work is poor quality and he doesn't show up. Is completely disillusioned about the amount of work he has done and the hours he has put into the project. Hires inexperienced people to work with him, which cost him money, then he passes the losses on to you. In addition, he has admitted that he has taken money from our project and put it into another project that he underbid. Our basement and yard are a complete mess and he has walked away from the project. Wanted to negotiate new terms with us paying more money, but he has not delivered what he was supposed to deliver with the amount of money he has been given. This guy is a crook. Beware.
