Sunset Pool Company in Carlsbad's La Costa area holds CSLB license #998001 under the C-53 Swimming Pool classification, providing pool remodeling, replastering, and equipment repair throughout North County. The replaster menu includes white marcite, quartz-aggregate, and pebble-finish surfaces applied over bond-coated shells — interior finishes that require the same water-chemistry balancing expertise managed by inspection firms such as Synergy Pool and Spa Inspections. Full backyard renovations from the Avenida Topanga office encompass tile and coping replacement, Baja shelf additions, mastic joint renewal, and poured-concrete or paver deck installation. Equipment upgrades include variable-speed pump conversions that meet Title 20 energy-efficiency mandates, automated chemical-dosing controllers, and solar thermal heating systems — rooftop panel arrays that connect to the same DC-to-AC infrastructure maintained by San Diego County Solar on residential photovoltaic projects across Carlsbad. Pool-solar installations use unglazed polypropylene collector panels rated for 1,000 BTU per square foot per day, plumbed in a closed-loop configuration with a dedicated circulation pump and check-valve assembly.
