Residential Plumbing Services Los Angeles
Built to the same standard as everything else.
Plumbing is the part of your house you never see, right up until something breaks. Then it's the only thing you care about. We run it like every other trade on our sites: licensed, permitted, and put together so the next person who opens the wall says whoever did this knew what they were doing. Our plumbers are on staff, not day-labor subs. They've been on Forma jobs for years, they show up, they do clean work, and they don't disappear halfway through. Most plumbing in Los Angeles falls into a handful of buckets. Here's what we run. Whole-home repipes. If your house went up before 1980 and still has its original galvanized supply lines, those pipes are rusting shut from the inside. You'll feel it as low pressure, see it as brown water in the morning, and fight it as pinhole leaks that keep coming back no matter how many times they're patched. A slab home with a persistent under-slab leak is usually telling you the same thing. We repipe the whole house in either PEX-A on a manifold (flexible, fast, freeze-resistant) or Type-L copper (longer-lasting, costs more). For most LA homes, PEX-A is the right answer. Figure 2 to 4 days for most houses. Water's off during work hours and back on at night until the new system is pressure-tested and cut over. Remodel plumbing. Moving a kitchen island, adding a bathroom, running a line out to an outdoor kitchen, plumbing a laundry room or a wet bar. We work off your architect's drawings and plan the rough-in around the design, not the other way around. Fixture installation. Brizo, Waterworks, Newport Brass, Kohler Stillness, Hansgrohe Axor, whatever the spec calls for. We've set enough high-end trim to know which brands hide which quirks (looking at you, rough-in plates that match no standard cutout). If your designer specs something new to us, we order the rough-in early so we can put hands on it before the wall closes. Sewer and drain lines. Older LA homes run cast-iron drains that scale up and crack, and clay sewer laterals that tree roots love. Before we promise anything, we put a camera down the line and show you what's actually there: root intrusion, a bellied section holding water, a cracked joint. Sometimes that's a spot repair. Sometimes it's a full replacement. We tell you which. Tankless water heaters. Navien, Rinnai, Noritz. We run the gas line, the venting, the recirculation loop, and the controls. Most installs take a day. We pull the permit and schedule the inspection. Gas lines. Range hookups, outdoor kitchens, fire features, pool heaters. Permitted with LADBS or the local jurisdiction, and pressure-tested before anyone signs off. Water filtration. Whole-home softeners, under-sink reverse osmosis, point-of-use carbon. We size the system to your actual water test, not a generic spec sheet. A typical one: a 1960s Bel Air home on its original galvanized supply, brown water and pinhole leaks that keep coming back. We repipe the whole house in PEX-A with a manifold in the garage, pull permits with LADBS, and run most jobs like that in about 4 days. No more brown water, no more leaks. Or a high-end primary bath, Brizo Litze in unlacquered brass throughout: wall-mount valve, rain head, hand-shower, brass linear drain in the pan. We template every rough-in off the tile spec so the trim lands at the exact reveal drawn on paper, then set it over Schluter Kerdi waterproofing flood-tested for 24 hours before a single tile goes down. If you want plumbing that holds up to the same standard as the rest of the house, that's what we do.

Our Process
A proven approach that keeps your project on track.
Assessment
We start with what's actually in the walls: pipe material, water pressure at the fixtures, and the age and condition of the water heater and shutoffs. On older homes we're checking for galvanized supply and cast-iron drains, and before a repipe we camera the sewer line so nothing surprises us once things are open.
Planning & Permits
We lay the runs out on paper, pull the permit with LADBS or the local jurisdiction, and sequence around the framing, cabinet, and tile schedule when it's part of a larger remodel. The rough-in gets planned around your design, not squeezed in around it.
Rough-In
We run the new supply, drain, gas, and vent lines and set the manifold on a repipe. Everything gets pressure-tested before a single wall closes, because a leak found now is cheap and a leak found later is not.
Finish & Inspection
We set the fixtures and trim to the reveal on the drawings, test every connection, pressure-test the gas, and get the city inspector out to sign off. What you're left with is a closed permit, not just the water turned back on.

Plumbing Services in Los Angeles Frequently Asked Questions
Three tells. Low pressure at more than one fixture. Brown or rusty water when you first run the tap in the morning. Pinhole leaks that keep coming back after they're patched. If the house was built before 1980 and still has its original galvanized supply, you're on borrowed time no matter how it looks today. A lot of pre-1980 LA homes need it inside the first year after a new owner moves in, once someone's finally running every fixture daily.
For most LA homes, PEX-A on a manifold. It's flexible, quick to install, shrugs off freezing, and doesn't corrode inside old walls the way copper eventually can. Copper still earns its place on short exposed runs and when you want the look of it. Both are good pipe. The wrong question is which one is premium. The right question is what your house actually needs, and for a full repipe in an old LA home that's usually PEX-A.
2 to 4 days for most LA homes. A raised foundation with a crawl space goes quicker, because we can run most of the new lines underneath. A slab home takes longer, since we're routing through walls and ceilings instead of under the floor. Either way, the water's off while we work and back on every night until we pressure-test the new system and cut everything over.
Yes, and most of our remodel work is exactly that. Kitchen islands, new bathrooms, outdoor kitchens, laundry rooms, wet bars. We plan the plumbing around your design instead of forcing the design to dodge the old pipes. If you're working with an architect, we build the rough-in straight off their drawings and flag anything that won't work before it gets framed.
Brizo, Waterworks, Newport Brass, Kohler Stillness, Hansgrohe Axor, whatever your designer specs. We've set enough of it to know the quirks each line hides, especially the rough-in valves that don't play nice with a standard cutout. When it's something we haven't handled before, we order the rough-in early so we can lay hands on it and template the trim before the wall closes.
More than you'd guess. On older LA homes we're usually looking at cast-iron or clay lines, and the camera shows us exactly where they've failed: tree roots pushing through a joint, a bellied section that holds water and grease, a cracked or offset pipe under the slab or the yard. Seeing it on screen is what tells us whether you're looking at a spot repair or a full lateral replacement, before anyone starts digging or quoting.
