Above-ground pools are the least expensive pool option, and usually the easiest and fastest to install. First, our installers level the ground to make a flat building surface. Then we assemble the perimeter track, which supports the metal and plastic outer wall. Next, we spread sand in the pool area and install the plumbing. Finally, we secure the vinyl liner over the pool walls, fill the pool with water, smooth the liner and fasten it into place. We then hook up the pump and filtering system. Your pool is now ready!
