There are no extras in complete swimming pool service that are not clearly described in our service contracts. We do not do business by signing you up and then coming back and saying “Oh, we forgot to mention…” and start to bill you for extras after the pool season starts. However, you may request, and we may agree, that additional work is needed and to be done. For that, we will quote prices and do work only once you have approved. As mentioned, any pool service company that is professional and honest should be able to quote you all service costs up front including extras and chemicals.
