DO NOT HIRE: The Crack Doctor is an awful company. The gave me the best customer serive I';ve ever had PRIOR to signing that deal to waterproof my basement. Once they had my bisness, it all went downhill. The sales rep had no idea what he was doing and misinformed my on the prioce and financing options. The work took way longer than expected and the company charged me more for the extra tims somehow. When we demo'ed the basement and found other HUGE issues, and I asked for a day off from their work to have other prefessionals (plumbers, electricians, etc) take a look, the owner, Michael, threatened to SUE ME for breach of contract. The job was complete but not satisfactory. My basement now has a 3 inch slant throughout, due to their poor grading of the internal drain system. Their product does come with a lifetime warranty however, and I have not had any further water in my basement, but whenever I call them to ask a question or request them to come fix their sagging membrane, I get the worst customer service ever! DO NOT HIRE!!
