A Hometown Company, Not a Franchise
Sedco Plumbing is locally owned and operated, holds a California C-36 plumbing contractor license, and is bonded and insured. Because we’re not a franchise, there’s no national call center between you and the person turning the wrench. You get a flat-rate quote before any work begins, a clean and respectful technician at your door, and a workmanship warranty backed by people you can actually find in town. That accountability is the whole point of hiring local.
The Plumbing Problems El Cajon Homes Actually Have
A large share of El Cajon’s housing went up between the 1950s and 1970s, most of it on slab foundations. That era produces two of our most common calls: slab leaks, where a pressurized line fails under the concrete, and aging galvanized supply lines that corrode from the inside until pressure slows to a trickle. In Fletcher Hills, Bostonia, and Granite Hills we see both every week, and we’ve shaped our leak detection and repiping work around them.
Water quality matters here too. Much of the local supply, delivered by Helix Water District, is imported Colorado River water that runs hard. All that mineral content builds scale inside water heaters, faucets, and shower valves, which is why tank flushes, softeners, and filtration systems are steady work for us. Add inland summers that push plumbing equipment hard, and El Cajon fixtures simply age faster than coastal averages suggest. When a job needs a permit, we pull it directly from the City of El Cajon and handle the inspection schedule ourselves.

Frequently Asked Questions
How fast can you get to my El Cajon home?
This is our home base, so El Cajon response times are the fastest we offer — most addresses in the city sit within a 10–15 minute drive of our technicians. Same-day service is the norm, and emergencies are prioritized on the schedule.
Do I need a permit for plumbing work in El Cajon?
Water heater replacements, repipes, and sewer work generally require a permit from the City of El Cajon, while minor like-for-like repairs usually don’t. We pull the permits and schedule the inspections, so you never have to manage any of it.
Why does my El Cajon water heater keep scaling up?
Local water is hard — much of it imported Colorado River supply — and dissolved minerals settle out as scale whenever water is heated. Regular flushes extend a heater’s life, and a softener or whole-house filtration system addresses the cause rather than the symptom.
