After getting bids from several bigger pool companies, we decided on Cornerstone. And are we ever glad! They created a beautiful pool for us at a very competitive rate. And quicker than the other guys would have. And the service didn't stop after the pool was built either. Any problems or questions in the years since have been addressed very quickly (the only problem was a small equipment breakdown). Cornerstone bent over backwards to make sure we got what we wanted... We couldn't be happier.
Pros: Price, service, design
