Once an above ground pool has been purchased we will come level the ground within two inches (more than two inches will be an extra charge). The pool will be installed within 1/4 inch of level, the pool base will be installed and the liner stretched properly so that there are no wrinkles. We will build the ladder, install the pump and filter system and leak test it. Once we are finished the customer turns off the water when the pool is full and starts the chemicals.
