You’re in the right place. At Benjamin Franklin Plumbing, plumbing is all we do — and we do it with the punctuality, professionalism, and local expertise that Peninsula homeowners deserve. Whether it’s a burst pipe on a rainy Tuesday night, a water heater that quit before your morning shower, or a slow drain you’ve been putting off for weeks, our licensed plumbers in San Mateo are ready to respond fast and fix it right.
We proudly serve the entire San Francisco Peninsula — from South San Francisco and San Bruno in the north to Palo Alto, Menlo Park, and Half Moon Bay in the south. Our team understands the specific plumbing challenges that come with Peninsula housing: older sewer laterals in established neighborhoods, slab construction common across mid-century developments, and the corrosive effects of Bay Area water chemistry on aging pipe materials.
From the tree-lined streets of Hillsborough to the bayside neighborhoods of Foster City and the coastal homes of Pacifica, we’ve worked across this corridor long enough to know what breaks, why it breaks, and how to fix it properly the first time.
If you’ve spotted our trucks near downtown San Mateo, along El Camino Real, or out toward the bayfront — that’s not a coincidence. We’re a consistent presence across the Peninsula because the communities here count on us.

Comprehensive Plumbing Services on the San Francisco Peninsula
Benjamin Franklin Plumbing focuses on residential plumbing. We don’t split our attention across HVAC, electrical, or general contracting. Every technician on our team is a specialist — which means faster diagnosis, sharper expertise, and more reliable outcomes for homeowners across San Mateo County and the broader Peninsula.
From routine maintenance to complex repairs, our plumbers handle everything your home’s water and drain systems need — under one roof, with one consistent standard of quality.
Drain Cleaning in San Mateo, CA
When store-bought solutions stop working and the same drain keeps backing up, it’s time to call a professional. Our drain cleaning service in San Mateo goes beyond clearing the symptom — we identify and treat the underlying cause so the problem doesn’t return in a few weeks.
Retail chemical drain cleaners can mask a developing blockage and, over time, degrade older pipe materials. Our technicians use professional-grade equipment that clears obstructions completely while protecting the integrity of your plumbing.
Our drain cleaning services across the Peninsula include:
- Hydro-jetting and mechanical rooter clearing
- Root intrusion removal from sewer laterals
- Preventive enzyme treatments for ongoing maintenance
- Video camera inspections to diagnose the root cause
- Full cleanup after every service call
San Mateo’s mature street trees, clay-heavy soils, and aging residential pipe infrastructure create drain conditions that recur without proper treatment. From older bungalows in Baywood to mid-century ranches in Belmont and newer townhomes in Foster City, our crews have cleared drains throughout this corridor. We know what drives recurring blockages on the Peninsula — and how to stop them.
According to the U.S. Environmental Protection Agency (EPA), household leaks and clogs can waste nearly 10,000 gallons of water per year. Addressing drain issues early protects your plumbing and keeps your water bill in check.

Emergency Plumber in San Mateo, CA
Plumbing emergencies don’t wait for business hours. A flooded utility room at midnight or a burst supply line on a Sunday morning demands an immediate, prepared response — not an answering machine. Our emergency plumbing service covers San Mateo and the full San Francisco Peninsula, available 7 days a week from 7AM to 7PM, with urgent response capabilities for situations that can’t wait.
Whether it’s a major pipe failure in a Hillsborough estate, a sewage backup in a Burlingame bungalow, or a sudden water heater flood in Redwood City, our emergency dispatch team is ready:
- Fast dispatch directly to your address
- Same-day or immediate appointment windows
- Clear diagnosis and honest explanation before any work begins
- Immediate damage control to limit water intrusion and cleanup costs
Our emergency plumbers arrive fully equipped — carrying the tools, parts, and field experience to resolve most issues on the first visit. We don’t make you wait on a second truck or a parts run. On the Peninsula, where home values are high and water damage costs are significant, that level of preparation matters.
The American Red Cross recommends that every homeowner know the location of their main water shut-off valve before an emergency strikes. Our technicians are always happy to walk you through your home’s shutoff location during any service visit — it’s a simple step that can prevent thousands of dollars in damage.
When you need an emergency plumber in San Mateo or anywhere on the Peninsula, we’re the team to call.
Leak Detection in San Mateo, CA
Hidden leaks behind walls and beneath foundations can cause serious structural damage for months before a homeowner notices anything unusual. By the time water stains appear or flooring starts to buckle, the repair cost is often far greater than it would have been with early detection. Our leak detection specialists serving San Mateo and the Peninsula use advanced, non-invasive technology to find problems fast:
- Acoustic listening sensors for pipe noise detection
- Infrared and thermal imaging cameras
- Video pipe inspection equipment
- Moisture meters and pressure differential testing
From slab leaks developing under post-war foundations in San Carlos and Belmont to slow pipe failures in the older residential areas of San Mateo’s North Shoreview neighborhood, we’ve located and repaired hidden leaks throughout this corridor. Once the source is identified, we repair or reroute the affected line with minimal disruption to your home.
Many Peninsula homes — particularly those built in the 1950s and 1960s in Millbrae, Burlingame, and San Mateo proper — still carry original galvanized or early copper plumbing. According to the U.S. Geological Survey (USGS), aging residential water infrastructure is among the leading contributors to hidden leak events. Those systems are vulnerable to pinhole corrosion, joint separation, and pressure-related failures that our equipment is built to catch early.
If you’ve noticed an unexplained jump in your water bill, warm or damp patches on your flooring, or the faint sound of running water with no fixtures on — don’t wait. Schedule an inspection before a manageable issue becomes an expensive one.

Water Heater Repair in San Mateo, CA
Losing hot water disrupts your household routine immediately — and often signals a developing mechanical issue that worsens without attention. Our water heater repair team serves San Mateo and surrounding Peninsula communities, working on both traditional tank units and modern tankless systems across all major brands and fuel types.
Our water heater services include:
- Full fault diagnosis and targeted repair
- Thermostat and heating element replacement
- Sediment flush and routine maintenance
- Energy-efficient upgrades and full system replacements
- Old unit removal and responsible disposal
Homeowners across Redwood City, Menlo Park, and Atherton rely on us because we deliver same-day appointments and honest assessments. We’ll tell you directly whether a repair makes financial sense or whether a replacement will serve you better in the long run — no pressure, just straightforward guidance.
The U.S. Department of Energy notes that water heating accounts for roughly 18% of a home’s total energy consumption. An aging or inefficient unit doesn’t just mean cold showers — it adds to your utility bill every month. Our technicians can evaluate whether your current system is performing at rated efficiency and advise on models that qualify for ENERGY STAR incentives.
Sewer & Pipe Repair on the San Francisco Peninsula
A cracked, root-invaded, or collapsed sewer line creates problems throughout your entire property — slow drains in every fixture, sewage odors, yard damage, and the risk of a full backup. Our sewer line repair services across San Mateo and the Peninsula include:
- Trenchless sewer repair and pipe lining
- Sewer camera inspections and full line mapping
- Targeted spot repairs for localized damage
- Full repiping for homes with severely deteriorated pipe systems
Many Peninsula communities — including older sections of San Mateo, Burlingame, and Millbrae — still rely on original clay or cast iron sewer laterals. These materials are highly susceptible to root intrusion, joint cracking, and gradual collapse, especially in neighborhoods with large, established trees. Our trenchless repair methods restore full sewer function without excavating your yard or destroying your driveway.
NASSCO (National Association of Sewer Service Companies) sets the professional standard for sewer pipeline inspection and assessment. Our technicians work to those protocols — meaning thorough camera inspections, accurate condition reporting, and repair work built to last.

Slab Leak Repair in San Mateo, CA
Slab leaks are among the most serious plumbing issues Peninsula homeowners face — and they’re more common here than many people realize. The combination of mid-century concrete slab construction, expansive Bay Area soils, and aging copper supply lines creates real conditions for pressurized pipe failures beneath the foundation. Our slab leak repair technicians serving San Mateo and the surrounding area provide:
- Advanced non-invasive slab leak detection
- Targeted excavation or full pipe rerouting
- Repair with preventive follow-up to protect the surrounding system
Warm or damp spots on your flooring, an unexplained spike in your water bill, or the faint sound of running water with no fixtures on — these are the classic warning signs. Acting early is almost always significantly less expensive than waiting until the damage spreads.
Our detection process identifies the exact failure point before any work begins, so we avoid unnecessary demolition and preserve as much of your flooring and foundation as possible. Homeowners in San Carlos, Belmont, and Foster City call us regularly for this kind of precise, low-disruption slab leak work.

Bathroom & Kitchen Plumbing in San Mateo, CA
Not every plumbing problem announces itself with a flood. A dripping faucet, a loose toilet base, or a garbage disposal that hums without draining can each cause slow, cumulative damage when left unaddressed. Our San Mateo plumbers handle all fixture installations, repairs, and upgrades, including:
- Toilets, sinks, and faucets — repair and replacement
- Shower and tub valve service
- Garbage disposal installation and repair
- Dishwasher hookup and drain line connection
From full bathroom updates in Hillsborough to straightforward faucet replacements in San Bruno, our technicians deliver clean, precise, leak-free work on every visit. We use quality materials, connect all work to current California code, and clean up completely before we leave.
The California Contractors State License Board (CSLB) requires all plumbing work in California to meet state licensing and code standards. Our team holds the required credentials and works to those standards on every job, every time.
Water Quality Solutions for Peninsula Homes

Hard water and mineral buildup are real concerns across the San Francisco Peninsula. San Mateo County’s municipal water supply is safe to drink, but it carries dissolved minerals that gradually wear down fixtures, water heaters, and appliances. Our water quality services address this directly:
- Water softener installation and setup
- Whole-home filtration systems
- Reverse osmosis drinking water units
- Salt-free conditioner systems for softer water without added sodium
Whether you’re in Woodside, East Palo Alto, or along the Half Moon Bay coastline, improving your water quality extends the life of your plumbing and appliances while improving your day-to-day experience. Many Peninsula homeowners pair a new water heater installation with a whole-home filtration system — protecting the unit from scale buildup from its first day of operation.
The EPA’s Drinking Water Standards define mineral thresholds for public systems, but softness, taste, and scale reduction are separate matters that home filtration meaningfully improves. If you’ve noticed buildup on your faucets or residue inside your dishwasher, a water quality consultation is a practical next step.
