I've been using Sherwin to open and close my pool since 1995. In any business, you'll never meet more reliable and honest people who treat their clients like valued customers. Additionally, they know everything there is to know about all types of pools. If they say the can fix a problem they fix it. And what they can't do, they don't attempt. For example, they don't install liners but referred Bilt-Rite Pols to do that. (See separate review).
