We come out to your house once a week on the same day and at about the same time. We test your swimming pool water and add the chemicals to keep the water balanced, keep the pool free of algae and bacteria. The chemicals are included in the price. We leave a Service Record card that we mark each week with the date and time of our visit. We communicate about pool conditions occasionally with a doorhanger. We maintain historical records about your pool conditions in a state of the art database storage and retrieval system. We turn your pool pump on during our visits so that the chemicals will circulate throughout the pool. If the pool ever turns green, we'll kill the algae at no extra charge.
