We couldn't be happier with the service from The Pool Lab. Joe looks after our pool regularly and has been absolutely fantastic. He has provided us with great advice on how to keep our pool in top shape, and recently recommended and set up a new Maytronics robotic pool cleaner. Thanks again for everything!
