Pool Doctor sells, repairs and warranties Pool and Spa covers. We come to your pool, conduct A/B measurements (for an exact mesh cover fit) or measure pool length and width for an auto-cover and with a deposit, we order and install your cover. With a Spa cover, we determine with your assistance, the size and drop of your spa cover, you select the color, material and center thickness and with a deposit, we order and deliver your cover. In either case, we warranty what we sell and we'll fix or repair what may be needed. Note: Natural wear, tear or rope stretching / breaking is generally not considered warranty repair unless associated with a manufacturing defect.
