Our Plumbing Services in Watertown

Every plumbing service you need, delivered by licensed professionals who know the Watertown area.

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.

Sump Pump Repair

Professional sump pump repair for residential and commercial properties. We diagnose electrical, mechanical, and float switch failures and return your pump to full working order with quality replacement parts.

Garbage Disposal

Professional garbage disposal installation and repair. We handle electrical connections, mounting flange replacement, and drain line connections for reliable, leak-free kitchen sink drainage.

Slab Leak Repair

Professional slab leak repair from detection through restoration. We use acoustic listening devices and thermal cameras to find the leak precisely, then repair or reroute the line to solve the problem permanently.

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.

Drain Cleaning

Professional drain cleaning using hydro-jetting and snaking to clear slow and clogged drains throughout your home. We remove grease, hair, roots, and mineral buildup — restoring full flow and preventing backups.

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.

Emergency Plumber

Around-the-clock emergency plumbing for burst pipes, slab leaks, sewer backups, gas leaks, and water heater failures. Our licensed emergency plumbers respond fast to stop damage and restore your plumbing.

Toilet Repair

Reliable toilet repair and installation for running toilets, phantom flushes, rocking toilets, weak flushes, and leaking seals. We diagnose the root cause and repair or replace components quickly and affordably.

Trenchless Sewer Repair

Professional trenchless sewer line repair for cracks, offsets, and root intrusion. Pipe lining creates a new pipe within the old one, while pipe bursting pulls a new pipe through to replace the failed line completely.

Grease Trap Cleaning

Regular grease trap cleaning for restaurants and food service operations. We pump and scrape grease traps on schedule and handle compliance documentation for health department inspections.

Water Line Repair

Expert water line repair using trenchless and conventional methods. We locate the break, recommend the most cost-effective repair approach, and restore your water service with minimal disruption to your property.

Sewer Line Repair

Professional sewer line repair that diagnoses the actual problem before recommending solutions. Camera inspection shows us exactly what is wrong so we can perform the least invasive, most cost-effective repair.

Tankless Water Heater Installation

Professional tankless water heater installation including new setups and tank-to-tankless conversions. We handle sizing, venting, gas supply upgrades, and permitting for code-compliant installations throughout the country.

Boiler Repair

When your boiler fails in winter, you need a plumber who understands hydronic systems. Our licensed technicians diagnose and repair all major boiler brands, restoring efficient heat to your home or building fast.

Faucet Repair

A dripping faucet wastes hundreds of gallons per month. Our licensed plumbers diagnose and repair kitchen, bathroom, and utility faucets of all brands and types — stopping leaks and restoring smooth operation.

Hydro Jetting

Hydro jetting service using high-pressure water to scour the interior of your drain and sewer lines. Removes grease, scale, tree roots, and years of buildup that mechanical snaking cannot reach.

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.

Leak Detection

Find hidden leaks before they cause serious damage. Our leak detection specialists use thermal cameras and electronic listening devices to locate leaks behind walls, under slabs, and underground with precision.

Commercial Plumbing

Professional commercial plumbing services for all business types. From emergency repairs that keep your doors open to scheduled maintenance that prevents downtime, we protect your business operations.

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.

Gas Line Repair

Professional gas line repair performed by licensed plumbers who understand gas system safety. We find the leak, repair or replace the damaged section, and pressure test the line before restoring gas service.

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.

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.

Backflow Testing

Backflow testing is required annually in many jurisdictions. We test your preventer, document the results, and submit paperwork to your local water authority — keeping you in compliance and your drinking water safe.

Common questions about plumbing services in Watertown, MA.

How much does a plumber cost in Watertown, MA?

How do I find a licensed plumber in Watertown, MA?

How do I prevent frozen pipes in Watertown, MA?

To prevent frozen pipes in Watertown, 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 Watertown?

Most Watertown 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 Watertown. Magnet Plumbing uses hydro-jetting and snaking to thoroughly clear all drain types.

What is trenchless sewer repair and is it right for my Watertown home?

Trenchless sewer repair in Watertown replaces damaged sewer lines using pipe lining or pipe bursting methods — without digging up your yard, driveway, or landscaping. It works for most sewer line problems including cracks, root intrusion, and offset joints. Magnet Plumbing uses camera inspection to confirm trenchless repair is the right approach for your specific line condition.

How can I tell if I have a slab leak in my Watertown home?

Signs of a slab leak in Watertown homes include unexplained increases in your water bill, warm or wet spots on the floor, the sound of running water when all fixtures are off, cracks in the foundation or walls, and low water pressure. If you notice these symptoms, call a plumber for professional slab leak detection before the damage worsens.
