Father-and-son pool service network with combined experience approaching three decades, Cool Pool Guys started in 2007 and routes residential and commercial pool calls across OB, Point Loma, La Jolla, and the broader San Diego coast. Routine maintenance covers chemical balancing, brushing, basket pulls, and DE-filter cleaning, with poolside hardscape and planting bed maintenance handed to Cabanas Landscape when overgrowth from bottlebrush and bird-of-paradise starts dropping debris into skimmers. Equipment work includes Pentair IntelliFlo and Hayward Super Pump variable-speed swaps, salt cell rebuilds on Hayward AquaRite chlorinators, and DE filter media changes — plus algae remediation calls during the late-summer green-water spikes that hit unstabilized pools after marine layer breaks. Pool deck and surrounding-fence repaint scopes that come up during a resurface get routed to Tony Pereira Painting, since the deck-coating, finish, and sealer work belongs to a different trade than the pool plaster crew. The most involved projects are full acid-wash and re-plaster jobs on stained or scaled vintage gunite pools in the older Sunset Cliffs and Loma Portal homes, where draining, multi-stage acid scrubbing, white-coat plaster application, and fill-and-balance can take a week of coordinated trades to bring the pool back to swimmable chemistry.
