Repiping & Plumbing Services in Pasadena, CA
Whole-House Repiping for Pasadena Homes
Most Pasadena homeowners who call a repipe company are calling about the same thing: a house whose water lines have outlived it. Much of the city was built before the Second World War, and the Craftsman, Spanish Revival, and period-revival houses that give neighborhoods like Bungalow Heaven and Madison Heights their character were typically plumbed in galvanized steel. That pipe was never meant to last a century. We replace it with copper or PEX as a single project, permitted through the City of Pasadena, and we work in these houses the way their owners expect: carefully, with the openings planned before anything is cut.
Replacing Galvanized Pipe in Pasadena’s Pre-War Houses
Galvanized steel is protected by a thin zinc coating. Once that coating wears through, the steel rusts from the inside, and the rust builds up on the pipe wall until the bore is a fraction of its original size. The symptoms arrive slowly enough that owners get used to them: a shower that weakens when someone runs a tap elsewhere, water that comes out brown after the house has sat empty for a weekend, and small leaks at threaded fittings, where cutting the threads left the least metal and the least coating. None of it improves on its own, and a repair on one run only moves the next failure somewhere else.
The good news in Pasadena is how many of the older houses are built. Many of the city’s bungalows sit on raised foundations over a crawl space, and that access changes the job. Most of the horizontal runs can be replaced from underneath the floor and brought up into each wall at the fixture, which keeps openings in the finished rooms to a minimum. Two-story houses need more access from above, and post-war homes, such as the ranch houses around Hastings Ranch, are a different layout again, with runs through the attic or walls instead. We walk the house first and show you where every opening will go.
Owners of period homes usually care most about what surrounds the pipe: original plaster, built-in cabinetry, and bathroom and kitchen tile that cannot be replaced like for like. We route around those wherever the house allows, using closets, the crawl space, and the backs of cabinets rather than feature walls. Where plaster does have to be opened, patching is part of the job, not an extra, and the walls are left ready for paint.
Copper or PEX, and What a Pasadena Repipe Costs
We install both, and the right choice depends on the house. Copper has the longest service record of any supply material; a properly installed Type L system routinely lasts fifty years and more, and many owners of Pasadena’s older homes choose it because they plan to stay. PEX is flexible, resists corrosion and scale, and follows existing cavities with fewer openings, which matters in a house with plaster walls. Where both are reasonable, we quote both, so you can decide on real numbers instead of a general rule.
What moves the price of a whole-house repipe is the house itself, not the zip code. The number of fixtures is the largest factor, followed by how the lines have to run (through a crawl space, an attic, or a slab), whether the house is one story or two, the material you choose, and whether there are additions, a guest house, or a rear unit on the same supply. We walk the property and give you a free written estimate for the complete job. The price we quote is the price you pay, and financing is available.
A repipe is also a sensible time to look at the rest of an older house’s plumbing. Pre-war homes here were commonly built with clay sewer laterals, and Pasadena’s mature street trees send roots into their joints. If the drains have been slow, a video camera inspection of the sewer line shows what is going on before you decide whether it needs any work at all.

Frequently Asked Questions
Do you serve Pasadena?
Yes. Pasadena is part of our regular Los Angeles County service area, a short drive from our base at 2508 W Beverly Blvd. in Montebello. Estimates, permits, pricing, and the warranty work exactly as they do everywhere else we serve.
My Pasadena Craftsman still has its original pipes. Is it time to repipe?
If the supply lines are still galvanized steel, almost certainly. Galvanized from that era is decades past its service life. Falling pressure, water that runs brown after the house has been sitting, and leaks at threaded fittings are the usual signs, and they get worse rather than better. A repipe replaces the whole failing system at once instead of paying for the leaks one at a time.
How can I tell whether my house has galvanized pipe?
Look where the line enters the house or at the water heater connections. Galvanized is dull gray steel joined with threaded fittings, and a magnet will stick to it. Copper is reddish-brown or darkened with age, and a magnet will not stick. Older homes have often been partly repiped over the years, so finding both is common; the remaining galvanized sections are usually what limits the pressure.
Copper or PEX: which is better for a Pasadena home?
It depends on the house and how long you plan to keep it. Copper has the longest track record and suits owners who intend to stay for decades. PEX needs fewer wall openings, which matters in a plaster-walled pre-war house, and it resists corrosion and scale. We install both, quote both where both make sense, and tell you which we would choose for your house.
What does a whole-house repipe cost in Pasadena?
It depends on the house rather than the neighborhood. The number of fixtures matters most, then whether the lines run through a crawl space, an attic, or a slab, one story or two, copper or PEX, and whether a guest house or rear unit shares the supply. We walk the property and give you a free written estimate for the complete job, and the price we quote is the price you pay.
How long does a repipe take?
A typical single-family home is repiped in one day. Your water is off for part of that day rather than the whole of it, so the house stays livable. Patching follows once the new system has passed inspection.
Will a repipe damage my plaster walls or original built-ins?
Far less than most owners expect. On a house with a raised foundation, much of the work happens from the crawl space, and we plan the remaining openings around built-ins, original tile, and feature walls before anything is cut. Patching is included, and walls are left ready for paint.
Do repipes in Pasadena need a permit?
Yes. Pasadena runs its own building department rather than going through Los Angeles County, and a repipe needs a permit and a passing inspection before the walls are closed. We can pull the permit for you, or you can pull it yourself if you prefer. When we pull the permit, we also meet the inspector. Every new system is pressure-tested before the walls are closed.
Can you repipe a bungalow court or small apartment building in Pasadena?
Yes. We plan multi-unit repipes in unit-by-unit phases, so occupied units stay occupied and water is back on by the end of each workday. See apartment and multifamily repiping for how we run a building project.
Why does my Pasadena sewer line keep backing up?
In an older home, it is usually tree roots in a clay lateral. Roots find the joints between clay sections and grow inside, and slow drains turn into backups. We run a camera through the line first, then recommend a spot repair or a full replacement based on the footage. Sewer work is permitted through the City of Pasadena and inspected before the trench is closed.
SoCalGas shut off my gas. How do I get it back on?
The order is fixed: find the leak, repair or replace the affected run, pass a pressure test and the city inspection, then SoCalGas restores service. We handle each step and coordinate the utility’s return. See gas pressure testing for what the test involves.
