Altadena's Foothill Plumbing Specialists
Plumbing built around Altadena's homes, not a generic service menu
Altadena sits at the base of the San Gabriel Mountains in unincorporated LA County, and the homes here tell the story of a century of building. Walk one block east of Lake Avenue and you'll find a 1920s craftsman bungalow with galvanized supply lines and cast iron drains. Two blocks up the hill, a 1970s slab-on-grade ranch with copper pipes that have been pinhole-leaking for years. Half a mile further, a 1990s subdivision on slab where the foothill soil shifts enough each dry season to stress the embedded supply lines.
We know these houses. The plumbing failures that show up in Altadena's specific housing stock are not generic problems with generic solutions: galvanized lines that have lost most of their interior diameter, sewer laterals with clay fittings and root intrusion on older Mariposa Street lots, hard-water scale from Lincoln Avenue Water Company supply. We diagnose and fix the actual issue, then explain what we found and what we did.
All permitted work is filed through the LA County Department of Public Works, as required for Altadena's unincorporated jurisdiction.
What We Do
Plumbing services for Altadena and the SGV
From emergency leak repairs to whole-home repipes, we cover the full range of residential and commercial plumbing needs across the foothill SGV corridor.
24/7 Emergency Plumber
Burst pipes, active leaks, backed-up sewers, and failed water heaters don't wait for business hours. We're available around the clock.
Emergency service →Slab Leak Detection & Repair
Altadena's foothill slab subdivisions are prone to copper pipe stress from soil movement. We locate leaks acoustically and thermally, without guessing or jackhammering blind.
Slab leak services →Water Heater Repair
Hard water from Altadena's foothill aquifer causes sediment buildup that cuts heater efficiency and life. We repair tank and tankless units fast.
Water heater repair →Drain Cleaning & Unclogging
Kitchen grease, bathroom hair, and tree-root intrusion into older clay laterals: we clear all of it, including mainline clogs with snaking and hydro jetting.
Drain cleaning →Repiping & Whole-Home Pipe Replacement
Altadena's pre-1960 craftsman bungalows are full of galvanized pipe at end of life. We repipe to PEX or copper, including work inside plaster walls.
Repiping services →Sewer Line Repair
Hillside drainage, tree-root intrusion in clay laterals, and older cast iron mains failing in mature Altadena neighborhoods are our bread and butter.
Sewer line repair →Pool Leak Detection & Repair
SoCal's drought conservation rules make undetected pool leaks costly. We use sonar and dye testing to locate and fix leaks without full drains.
Pool leak services →Water Heater Installation & Replacement
Tank, tankless, gas, electric: we size, supply, and install code-compliant water heaters with proper venting and expansion tanks as required.
Water heater install →Leak Detection
Hidden leaks behind walls and under floors can go months without a visual sign. We use acoustic, thermal, and electronic detection to find them without exploratory demolition.

Why Altadena plumbing is different from the rest of the SGV
Altadena is one of the few unincorporated communities in LA County with a genuine range of housing ages all in one place. The oldest sections along Allen Avenue and Mt. Curve Avenue date to the Arts & Crafts era: homes built for craftsmen and their families in the 1910s and 1920s, plumbed with galvanized steel supply lines and cast iron drain stacks that were never meant to last this long.
Move south toward Lincoln Avenue and the housing shifts to post-war ranch: 1950s and 1960s construction, usually on slab, with early copper supply that's developed pinhole corrosion from the moderately hard foothill aquifer water. Move north toward Farnsworth Park and Eaton Canyon, and you hit the hillside lots where sewer lateral slope and root intrusion from mature trees are the bigger concerns.
Each neighborhood has its own common failure modes. We approach Altadena jobs with that geographic context — not a one-size-fits-all diagnostic script.
SGV Regional Specialties
Three services Altadena homeowners call us about most
Slab leaks, galvanized repipes, and pool leaks are the defining plumbing challenges of the foothill SGV. Each one demands specific equipment and knowledge of how Altadena homes were built.
Slab Leak Detection & Repair
In Altadena's foothill slab subdivisions (the ranch homes and mid-century moderns that fill the Country Club Drive area and the newer pockets below Lincoln Avenue), copper supply lines run through or under the slab. The alluvial soil at the base of the San Gabriel Mountains shifts during dry seasons and after rainfall, putting lateral stress on those embedded pipes.
A slab leak can run silently for months. The first sign is usually a water bill that climbs 20 to 40 percent without explanation, or a warm spot on a tile or hardwood floor above a hot water line. We locate leaks with acoustic listening equipment and thermal imaging before deciding on the repair approach. Epoxy pipe lining, above-slab rerouting, or targeted penetration are all options depending on pipe age and condition.
Slab leak detection & repair in Altadena →Galvanized Repipe for Craftsman & Bungalow Homes
Galvanized steel supply pipe corrodes from the inside out. After 50 or 60 years, the interior narrows (sometimes to less than half the original diameter) and water pressure at the fixtures starts to drop. When you turn on the kitchen tap, shower pressure dips. Orange or rust-colored water shows up in the morning before the line clears. These are late-stage signs of galvanized pipe failure in Altadena's older housing stock.
We replace galvanized supply systems with PEX or copper, working inside plaster walls and crawlspaces with minimal disruption to original finishes where that matters. We've done repipes in craftsman bungalows along Mariposa Street and Lincoln Avenue where the homeowner's goal was preserving as much of the original interior as possible. That's a different job than a repipe in a 1960s ranch, and we approach it that way.
Repiping services for Altadena homes →Pool Leak Detection & Repair
SoCal homes with pools aren't just dealing with a maintenance issue when a leak develops. LA County's water conservation requirements and the ongoing California drought mean an undetected pool leak translates directly to wasted water and higher bills. Losing an inch of water a day beyond normal evaporation points to a leak in the plumbing, shell, or fittings.
We use sonar leak detection and pressure testing on return and suction lines to locate leaks precisely. Dye testing identifies shell cracks and skimmer fittings that are seeping slowly. We serve pools across Altadena, Pasadena, La Cañada Flintridge, and the broader SGV foothill corridor, and we repair what we find the same visit when parts and access allow.

Common Questions
Frequently asked plumbing questions: Altadena & SGV
Do you offer 24/7 emergency plumbing service in Altadena?
Yes. We provide 24/7 emergency plumbing service throughout Altadena and the SGV. Whether a pipe bursts at 2 a.m. or a water heater fails over the weekend, you can reach us at (844) 981-1691 any time. The line goes to a live dispatcher, not an answering service.
What areas do you serve from Altadena?
We serve Altadena and the surrounding San Gabriel Valley foothill corridor, including Pasadena, La Cañada Flintridge, Sierra Madre, South Pasadena, San Marino, Glendale, La Crescenta, Eagle Rock, Arcadia, Highland Park, Atwater Village, and Montrose. We also serve Altadena's own neighborhoods from West Altadena and Christmas Tree Lane to the Las Flores and Chapman Woods areas in the east.
Is your work permitted through LA County?
Altadena is unincorporated LA County, so plumbing permits are issued through the LA County Department of Public Works. We pull all required permits for permitted work: slab penetrations, sewer line replacement, water heater installation, gas line work. We coordinate inspections on your behalf. Work that doesn't require a permit (like clearing a drain or replacing a faucet) we handle same-day.
Do you repair galvanized pipes in older Altadena homes?
This is one of our most common calls. Altadena's craftsman bungalows and pre-1960 ranch homes were often plumbed with galvanized steel supply lines that corrode from the inside over decades. Low water pressure, rust-colored water, and visible corrosion at exposed pipe joints are the usual signs. We offer full galvanized repipes using PEX or copper, including partial repipes when only a section has failed and a full replacement isn't needed yet.
Do you provide free estimates?
Yes. We provide free estimates on non-emergency service calls. Call (844) 981-1691 and we'll schedule a time to assess the job and give you an upfront price before any work starts. On emergency calls, we'll give you a price before beginning work. We don't start a job and surprise you with the bill afterward.
