Our Plumbing Services in Los Altos

From 24/7 emergency response to complete repiping, we handle every plumbing need for homes and businesses in Los Altos, CA.

Sewer Camera Inspection

Video sewer inspection reveals exactly what is happening inside your sewer line — no guesswork, no unnecessary excavation. Essential for pre-purchase inspections and diagnosing recurring sewer problems.

Sump Pump Repair

Emergency sump pump repair when flooding threatens your basement or crawl space. We diagnose failed floats, clogged intakes, and seized impellers fast — getting your pump back online before water damage spreads.

Drain Cleaning

Thorough drain cleaning that goes beyond surface blockages. We use video inspection and high-pressure water jetting to clear obstructions completely, leaving your drains flowing freely and reducing future buildup.

Commercial Plumbing

Full-service commercial plumbing for restaurants, offices, retail, multi-family, and industrial properties. We handle new construction, maintenance contracts, fixture replacement, and urgent repairs.

Gas Line Repair

Licensed gas line repair for natural gas and propane systems. We use pressure testing and calibrated gas detectors to locate leaks and perform safe, code-compliant repairs to restore your gas service.

Trenchless Sewer Repair

Trenchless sewer repair replaces damaged sewer lines without digging up your yard, driveway, or landscaping. We use pipe lining and pipe bursting methods to save time, money, and the mess of conventional excavation.

Slab Leak Repair

Expert slab leak detection and repair using electronic sensors and thermal imaging to pinpoint leaks under your foundation. We perform minimally invasive repairs to protect your structure and stop water waste.

Water Heater Repair

No hot water? Our licensed plumbers diagnose and repair water heater problems on the first visit whenever possible. We service all major tank and tankless brands and carry common repair parts on our service vehicles.

Garbage Disposal

When your garbage disposal jams, leaks, or stops working, our plumbers diagnose the problem fast. We repair what makes sense and replace units that are beyond repair with quality new disposals.

Water Heater Replacement

Water heater replacement with same-day or next-day installation in most areas. We remove your old unit, recommend the right size and model for your needs, and install your new water heater to code.

Hydro Jetting

Commercial and residential hydro jetting for persistent drain and sewer problems. We use calibrated pressure and nozzle selection for your specific line type, delivering a thorough clean without damaging pipes.

Repiping

Whole-home and partial repiping to replace aging galvanized, polybutylene, or deteriorated pipes with modern long-lasting materials. Repiping eliminates chronic leaks, low pressure, and discolored water permanently.

Toilet Repair

Professional toilet repair and installation. We diagnose running, leaking, rocking, and weak-flushing toilets and restore full performance with quality replacement parts. New installations handled the same way.

Water Line Repair

Water line breaks can disrupt your entire home's water supply. Our licensed plumbers repair or replace damaged main lines and service connections quickly, restoring full water pressure and flow to your property.

Pipe Repair

Professional pipe repair for leaks, corrosion, and breaks in supply lines, drain lines, and waste pipes. Our licensed plumbers diagnose the cause and perform lasting repairs using quality materials.

Boiler Repair

Professional boiler repair for banging noises, lost pressure, pilot failures, and circulation problems. We service atmospheric, condensing, and high-efficiency units — including expansion tanks and circulator pumps.

Gas Leak Detection

Accurate gas leak detection before small leaks become emergencies. We test your entire gas system using professional detection equipment and pressure gauges, identify any leaks, and perform safe code-compliant repairs.

Sump Pump Installation

Sump pump installation and replacement for basements and crawl spaces prone to flooding. We size the right pump, install primary and battery-backup units, and ensure reliable operation before every rainy season.

Backflow Testing

Professional backflow prevention testing and device installation. Our certified plumbers service residential and commercial properties, protecting your potable water supply from contamination.

Faucet Repair

Professional faucet repair and installation that eliminates drips, leaks, and stiff handles. We carry common repair parts on our trucks for same-visit repairs on most faucet brands, plus full installations of new fixtures.

Tankless Water Heater Installation

Tankless water heater installation for endless hot water without standby energy loss. We size, install, and commission all major tankless brands — and convert tank systems to more efficient tankless setups.

Emergency Plumber

When a plumbing crisis hits, you need a licensed plumber immediately. We answer emergency calls around the clock and dispatch crews fast — stopping leaks, restoring water service, and preventing further damage.

Grease Trap Cleaning

Grease trap maintenance keeps your kitchen drains flowing and your business compliant with local waste regulations. We provide scheduled pumping, manifesting, and inspection-ready documentation.

Leak Detection

Advanced leak detection using thermal imaging, electronic sensors, and pressure testing to find hidden leaks in walls, floors, and underground. Accurate detection prevents costly water damage and unnecessary demolition.

Sewer Line Repair

Sewer line repair and replacement for cracked, collapsed, root-infiltrated, and offset pipes. We use camera inspection to diagnose the problem and recommend spot repairs, pipe lining, or full replacement.

Frequently Asked Questions

Have questions about plumbing in Los Altos? We have answers.

How much does a plumber cost in Los Altos, CA?

Plumber rates in Los Altos typically range from $100 to $250 per hour depending on the type of work and time of day. Common jobs like drain cleaning run $150 to $300, while slab leak repair and repiping projects cost significantly more. Magnet Plumbing provides free estimates so you know the full cost before any work begins.

What causes low water pressure in Los Altos homes?

Low water pressure in Los Altos homes is often caused by mineral deposits clogging aerators and pipes, a partially closed shutoff valve, a failing pressure regulator, or a hidden water line leak. Corroded or deteriorated pipes in older Los Altos properties can also restrict flow significantly. A licensed plumber can diagnose the specific cause and recommend the right fix.

How do I prevent frozen pipes in Los Altos, CA?

To prevent frozen pipes in Los Altos, insulate exposed pipes in unheated areas like garages, crawl spaces, and attics. Keep cabinet doors under sinks open during cold snaps. Let faucets drip slightly during freezing temperatures. If a pipe does freeze, call Magnet Plumbing immediately rather than attempting to thaw it yourself to avoid a burst.

How often should I have my drains cleaned in Los Altos?

Most Los Altos homeowners benefit from professional drain cleaning every 1 to 2 years as preventive maintenance. Homes with large families, frequent cooking, or older plumbing may need service more often. Tree roots, grease buildup, and hair are the most common causes of drain problems in Los Altos. Magnet Plumbing uses hydro-jetting and snaking to thoroughly clear all drain types.

When should I replace my water heater in Los Altos, CA?

Most tank water heaters last 8 to 12 years. Consider replacement when your unit is over 10 years old, produces rusty or discolored water, makes rumbling or popping noises, or requires frequent repairs. Magnet Plumbing offers free water heater assessments to help Los Altos homeowners decide between repair and replacement.

What should I do if I smell gas in my Los Altos home?

If you smell gas in your Los Altos home, do not operate any electrical switches, open flames, or appliances. Leave the building immediately, leaving doors open as you go. Call your gas utility from outside or from a neighbor, then call Magnet Plumbing for emergency gas line inspection. Do not re-enter until a professional has cleared the property.
