Plumber in Palo Alto, CA
What Palo Alto Homeowners Call Us For
We provide full-service residential plumbing across all three Palo Alto zip codes and the surrounding Peninsula. Here is what keeps our phones busy:
Snaking, hydro jetting, and camera inspections for clogged and slow drains. Palo Alto's established neighborhoods are full of mature heritage oaks, redwoods, and ornamental trees whose root systems have been growing toward clay and cast iron drain lines for decades. In neighborhoods like Barron Park, Old Palo Alto, and the tree-canopied streets near Walter Hays Elementary, root intrusion is the leading cause of recurring sewer and drain blockages. We use HD camera inspection to identify exactly where roots are entering so we can address the problem at its source rather than just clearing it temporarily.
Repair, replacement, and tankless installation. Palo Alto's water comes from the Hetch Hetchy system and is naturally soft, which means water heaters here tend to accumulate less scale than in cities like San Jose or Campbell. That said, most tank water heaters in Palo Alto homes built before 1975 have already been replaced at least once, and the current units may be approaching the end of their 10 to 15 year lifespan. We service and install all major brands including Rinnai, A.O. Smith, and Navien, and design tankless systems for homes where demand has increased due to remodels or additions.
Camera inspection, repair, and full sewer line replacement. Palo Alto's sewer system is maintained by the city, but the lateral from your home to the city main is the homeowner's responsibility. In pre-war neighborhoods, these laterals are often original clay pipe that has been in the ground for 80 to 100+ years. In mid-century neighborhoods, Orangeburg (bituminous fiber) pipe was commonly used and is prone to collapse and deformation after 50 to 60 years. We camera-inspect the full lateral before recommending repair or replacement, and offer trenchless options when site conditions allow.
Whole-house and partial repipes for homes with galvanized steel, aging copper, or mixed-material supply lines. This is one of our most requested services in Palo Alto, particularly in homes built before 1960 that still have original galvanized piping. The internal corrosion that builds up inside galvanized lines over 60+ years restricts flow, produces discolored water, and eventually leads to pinhole leaks and pipe failures. We also have extensive experience repiping Eichler homes, where slab-on-grade construction requires rerouting new supply lines through the attic or interior wall cavities to avoid cutting into the concrete slab.
Water Filtration and Softeners
Whole-house treatment systems matched to your water source. Palo Alto's Hetch Hetchy-sourced water is soft and clean by Bay Area standards, but the city's aging distribution mains can introduce sediment and particulates into your home's supply. For homeowners with premium fixtures, high-end kitchen appliances, or concerns about disinfection byproducts from chloramine treatment, a whole-house carbon and sediment filtration system provides an additional layer of protection.
Faucet, toilet, shower, and garbage disposal repair and installation. From upgrading a kitchen faucet in a remodeled Crescent Park Colonial to installing a low-flow toilet in a Midtown ranch, we handle the full range of residential fixture work and ensure new installations integrate properly with your home's existing supply and drain systems.
Same-day response for burst pipes, sewer backups, water heater failures, and active leaks throughout all Palo Alto neighborhoods. In a city where homes routinely sell for $3 million to $8 million and above, water damage to hardwood flooring, plaster walls, or finished lower levels is not just an inconvenience. It is a threat to the value of your property. We dispatch quickly and isolate the source before beginning any repair.
Pre-purchase inspections, annual maintenance assessments, and full-property diagnostics. Palo Alto's competitive real estate market often moves fast, and understanding the condition of a home's plumbing before you close can save you from inheriting a $15,000 repipe or a $20,000 sewer lateral replacement that was not disclosed during the sale.
Palo Alto's Housing Stock and What It Means for Your Plumbing
Understanding what is behind your walls starts with knowing when your home was built. Palo Alto's development happened in distinct waves, and the plumbing materials and methods used in each era create specific challenges that show up on a predictable timeline.
Pre-War Homes: North of Oregon Expressway (94301)
The oldest residential neighborhoods in Palo Alto, including Professorville, Crescent Park, Community Center, and Downtown North, contain homes built from the 1890s through the 1940s. Professorville is a registered National Historic District where Stanford's earliest faculty built homes along Kingsley, Lincoln, and Waverley Avenues. Many of these homes are architectural landmarks in their own right.
The plumbing in this era of construction was typically galvanized steel for supply lines and cast iron for waste and drain. Sewer laterals were clay. At 80 to 130+ years old, the original plumbing in these homes is beyond its expected lifespan by any measure. What we commonly find in pre-war Palo Alto homes includes severely corroded galvanized supply lines with restricted flow and rust-contaminated water, cast iron drain lines with internal scaling and joint failures, and clay sewer laterals with extensive root intrusion and joint separation.
Repiping a pre-war home in Professorville or Crescent Park requires extra care, as many of these properties have been designated historic or have design review requirements. We plan pipe routing to avoid exterior changes that could trigger additional permitting, and we use existing wall and ceiling cavities wherever possible to minimize disruption to original plaster, trim, and finishes.
The Eichler Neighborhoods: South of Oregon Expressway (94303, 94306)
Joseph Eichler built approximately 2,700 homes across Palo Alto during the 1950s and 1960s, making this city one of the largest concentrations of Eichler architecture in the country. Neighborhoods like Green Gables, Greenmeadow, Fairmeadow, Charleston Meadows, and Palo Verde are defined by the Eichler signature: slab-on-grade concrete foundations, post-and-beam construction, radiant floor heating (in many models), floor-to-ceiling glass, and open floor plans.
Eichler homes present unique plumbing challenges that not every plumber is equipped to handle. The original copper supply lines and cast iron waste pipes were installed beneath or within the concrete slab. Over 60+ years, copper supply lines embedded in concrete can develop pinhole leaks from electrolysis or contact with the alkaline concrete. When an under-slab supply line fails, the only sign may be a warm spot on the floor, the sound of water running when nothing is turned on, or a spike in your water bill.
The standard repair approach for an Eichler with failing under-slab supply lines is a full repipe that reroutes new supply lines through the attic space and down through interior walls, abandoning the slab lines entirely. This is a project we have completed in Eichler neighborhoods across the South Bay, including in Mountain View, Cupertino, Los Altos, and Saratoga. We understand the construction, we know where the beams are, and we work efficiently to minimize the number of ceiling and wall access points needed.
For Eichlers with radiant floor heating, plumbing work requires additional awareness of the copper heating loops embedded in the slab. Accidentally hitting a radiant heating line during any slab-adjacent work can be extremely costly to repair. Our crew is trained to identify and avoid radiant loop locations before beginning any work in the slab area.
Post-War Ranches and Transitional Homes (1945 to 1970)
Not every home south of Oregon Expressway is an Eichler. Neighborhoods like Midtown, Barron Park, and portions of Charleston and Ventura include standard post-war ranch homes that were built by other developers during the same era. These homes share similar plumbing materials with Eichlers (copper supply, cast iron drain, clay sewer) but are built on raised foundations with crawl spaces rather than slabs.
Crawl space construction actually makes plumbing work more accessible, since supply and drain lines running beneath the floor can be reached without cutting through concrete. However, crawl spaces in older Palo Alto homes can have their own issues: low clearance, moisture accumulation, and decades of sediment that can make visual inspection difficult. We include a thorough crawl space assessment as part of any plumbing inspection or repiping evaluation in these homes.
Palo Alto's Water Supply and Your Plumbing
The City of Palo Alto operates its own utilities department, making it one of the few cities in the region that manages water delivery as a municipal service rather than relying on a private utility. Palo Alto's water supply comes primarily from the San Francisco Public Utilities Commission's Hetch Hetchy Reservoir, sourced from Sierra Nevada snowmelt. This is the same high-quality surface water that serves Menlo Park and Atherton via the Bear Gulch District.
Hetch Hetchy water is naturally soft, with hardness levels well below the 75 ppm threshold that defines moderately hard water. For Palo Alto homeowners, this translates to less scale buildup in water heaters, longer fixture life, and fewer issues with mineral deposits on glass and tile compared to cities served by groundwater, like much of San Jose.
The SFPUC treats the water with chloramine (a combination of chlorine and ammonia) for disinfection. While this keeps the water safe throughout the distribution system, some homeowners notice a faint chlorine taste or smell, particularly in older parts of the system where water may sit longer in the mains before reaching your tap. A whole-house carbon filtration system removes chloramine and its byproducts, and is a popular upgrade for Palo Alto homeowners who want the cleanest possible water at every fixture.
Palo Alto's distribution infrastructure includes mains that range from recently replaced to over 80 years old. Older mains can introduce sediment and particulates into your home's water. If you notice intermittent cloudiness or tiny particles, especially after city crews have been working on mains or hydrants in your area, a whole-house sediment filter provides reliable protection.

Remodels, Additions, and ADUs in Palo Alto
Palo Alto homeowners invest heavily in their properties. Kitchen and bathroom remodels, primary suite additions, garage conversions, and accessory dwelling units are all common projects, and each one has a plumbing component that needs to be planned carefully.
For older homes, a remodel is the ideal time to address aging infrastructure. If your walls are already open for a kitchen renovation, running new supply lines is a fraction of the cost and disruption compared to doing it as a separate project later. We evaluate the condition of existing plumbing during the planning phase and flag anything that should be upgraded while access is available.
ADU construction has become increasingly popular in Palo Alto as homeowners look to add rental income or accommodate family. Each ADU requires new plumbing connections for supply, waste, and a dedicated water heater. The City of Palo Alto's Development Services Department reviews building permits, and the plumbing must comply with the city's plumbing code. We handle the full permitting and inspection process for ADU plumbing and coordinate with general contractors to keep the project on schedule.
Eichler remodels deserve special mention. Opening up an Eichler kitchen or adding a bathroom requires routing new supply and drain lines in a home without a crawl space. Every pipe must be routed through attic space, interior walls, or carefully channeled through the slab. Our experience with Eichler construction across the South Bay means we know the structural layout before we start, which reduces surprises and keeps the project moving.

Frequently Asked Questions
How quickly can you reach my Palo Alto home in an emergency?
We dispatch from San Jose and reach most Palo Alto addresses in 20 to 28 minutes depending on the neighborhood and route. Active leaks and sewer backups are always prioritized. We carry the equipment to isolate and begin repairing most emergencies on the first visit so you are not waiting for a follow-up while water damage accumulates.
I have an Eichler home with a slab leak. What are my options?
Slab leaks in Eichlers typically require either a spot repair through the slab (if the damage is isolated to one location) or a full repipe that reroutes new supply lines through the attic and interior walls, abandoning the under-slab piping entirely. The right approach depends on the age of the piping, the number of previous repairs, and whether the home has radiant floor heating. We start with leak detection and camera inspection to determine the scope before recommending a path forward.
My home is in Professorville. Does the historic designation affect plumbing work?
Professorville's National Historic District designation primarily governs exterior alterations. Interior plumbing work, including repipes and drain line replacement, is generally not affected. However, if exterior access is needed for a sewer lateral replacement, the work may need to be planned to avoid visible changes to the streetscape. We coordinate with the City of Palo Alto's permitting department on any project that touches the exterior of a designated or potentially historic structure.
What kind of water does Palo Alto have?
Palo Alto receives its water from the City of Palo Alto Utilities Department, which purchases supply from the SFPUC's Hetch Hetchy system. This is naturally soft Sierra Nevada surface water, which is significantly gentler on plumbing systems than the groundwater used in much of the South Bay. The city treats the water with chloramine for disinfection. While the water is safe and meets all state and federal standards, some homeowners install whole-house carbon filtration to remove chloramine taste and disinfection byproducts.
Do you pull permits for plumbing work in Palo Alto?
Yes. The City of Palo Alto's Development Services Department handles building permits, including plumbing permits for projects like repipes, water heater installations, sewer lateral replacements, and new plumbing for remodels or ADUs. We manage the full permit and inspection process and are familiar with Palo Alto's specific requirements, which differ in some respects from neighboring Santa Clara County jurisdictions.
Should I get a plumbing inspection before buying a home in Palo Alto?
Absolutely. Given the age and variety of Palo Alto's housing stock, and the price points at which homes sell, a thorough plumbing inspection is one of the smartest investments a buyer can make. We assess supply line material and condition, drain and waste systems, the water heater, sewer lateral condition via camera, water pressure, and fixture function. For Eichler homes, we also check for signs of under-slab leaks and evaluate the condition of radiant heating connections where applicable.
How does repiping an Eichler differ from repiping a standard home?
Eichlers are built on concrete slabs with no crawl space, which means there is no easy access to supply lines running beneath the floor. A standard home with a raised foundation and crawl space allows plumbers to run new lines underneath the house. In an Eichler, new supply lines are routed through the attic space and brought down through interior walls to each fixture. This requires planning around the post-and-beam structure and careful ceiling access. We have completed this work across hundreds of Eichlers in Palo Alto, Mountain View, Cupertino, and Los Altos, and know these homes inside and out.
