depends on the amount of damage, what is damaged... size of blowers if necessary, pumps, dryers, ... had a cellar flood, servpro came emptied out all in finished basement, removed 2 ft of all drywall around cellar walls and inner walls, ran blowers, dehumidifiers, stored all salvaged items, washed and cleaned etc... my ins. covered it due to it being a hose popping on washer and water ran for 2 days while I was out of town.. and the lesson here is always use shut off and put to off after wash is done or washer not in use... i also had contractor come in to redo finished basement new drywall in lower areas, and more.... came to over 13k for the project and ins. paid most of it, except the deductible and some upgrades i made in the rehab process
