TV advertisement looked like it would work, didn't have good experience with other contractors in the past to have them even come for an estimate for other projects we had, the literature was very educational and addressed the problems I was experiencing--it made me believe that you knew what you were doing. Also, in our job you also used CleanSpace Footer Wrap, IceGuard, and LawnScape Outlet, and did 3 cast in place footings, and 22 PowerGuards that I couldn't fit in products installed space above.
