About plumbing in Laguna Hills
Laguna Hills has older housing than Rancho Santa Margarita. Of the roughly 12,100 housing units counted by the Census, 48 percent were built before 1980, against 4 percent in Rancho Santa Margarita, and the median home dates from 1980 itself. Age shows in the plumbing: copper that has carried hard imported water for decades wears thin and opens pinholes, water heaters installed in earlier decades are past their service life, and sewer laterals beneath mature trees take in roots. That lateral, which runs out to the public main, is the homeowner's.
Nellie Gail Ranch is the city's hillside neighborhood, laid out on large equestrian lots. Hillside grading brings pressure swings, and over time those swings wear out the regulator that protects the house. A failing regulator lets the extra pressure through to faucets, toilet fill valves, hoses and the water heater, so the plumber measures the pressure with a gauge before a new one is set.
Fifty-five percent of the homes in Laguna Hills are single-family detached houses. The other 45 percent are condos, townhomes and apartments, where neighbors share walls and drain stacks. A stain on a ceiling there may come from another unit or from a common line, so the source is tracked down before anything is opened, and work on shared plumbing is coordinated with the HOA.
Mission Viejo, which borders Laguna Hills, has the nearest of our 10 locations, and help is sent from there at any hour, weekends and holidays included. The City of Laguna Hills is the permit authority for a repipe, new gas piping, a sewer lateral job or a water heater replacement. A replacement water heater is secured with two seismic straps and its relief valve drains to a safe place, a gas line is pressure tested before it is signed off, and the city inspection closes the permit.
Laguna Hills is bordered by Mission Viejo, Lake Forest, Irvine, Laguna Woods, Aliso Viejo and Laguna Niguel. Those places are on our list too, and a call from any of them goes to our location closest to the address. A real person answers the phone at any hour, the cause is pinned down before a wall or floor gets opened, and you approve a written estimate before the plumber begins.
