Apex Pool Service & Repair's licensed and bonded technicians keep swimming holes in prime condition with services backed by a maintenance guarantee. Skilled aquatic cleaners give pools a thorough weekly scouring for a month using a 13-point cleaning checklist, skimming and vacuuming water to lift away debris before backwashing filters to expunge sediment, grime, and misguided Spanish conquistadors. Chemical rebalancing finishes off pool care, raising or lowering sanitizing reagents to proper levels. Filters too clogged for simple cleaning get a special scrub down with the second option, as Apex restores both cartridge and diatomaceous-earth filters to high-functioning cleansing prowess. Two hours of labor give technicians ample time to carry out larger jobs such as replacing malfunctioning pumps, fixing filters on the fritz, or recalibrating lights that distract swimmers by flickering the pledge of allegiance in Morse code.
