Our Plumbing Services in Alton

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

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.

Gas Leak Detection

Gas leaks are a serious safety hazard. Our licensed plumbers use professional gas detection equipment to find leaks in supply lines, fittings, appliances, and meters — and recommend immediate repairs to protect your family.

Tankless Water Heater Installation

Upgrade to on-demand hot water with professional tankless water heater installation. Our plumbers assess household demand, recommend the right model, and install with all required gas or electrical connections.

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.

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.

Emergency Plumber

Plumbing emergencies happen day and night. Our 24/7 emergency plumbers arrive quickly with the tools and materials to handle any urgent plumbing situation — protecting your property and restoring service fast.

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

Commercial plumbing needs are different from residential. Our plumbers understand backflow requirements, floor drain regulations, grease trap compliance, and the scheduling demands of active business operations.

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.

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.

Backflow Testing

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

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.

Water Heater Repair

Fast water heater repair for tank and tankless units. We diagnose and fix pilot light failures, thermostat issues, heating element problems, pressure relief valve malfunctions, and sediment buildup quickly.

Pipe Repair

Reliable pipe repair throughout your home — from pinhole leaks in copper supply lines to cracked drain pipes and corroded fittings. We diagnose the root cause and fix the problem at the source.

Faucet Repair

Expert faucet repair and installation for dripping, leaking, and hard-to-turn faucets in kitchens, bathrooms, and utility areas. We repair or replace cartridges, O-rings, seats, and stems — or install new fixtures.

Boiler Repair

Boiler repair and installation for residential and commercial hydronic heating systems. We service gas, oil, and electric boilers for reliable winter heating — diagnosing pressure, circulation, and combustion issues.

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.

Sewer Camera Inspection

High-definition sewer camera inspection for residential and commercial properties. Our plumbers document the condition of your sewer line and provide a copy of the footage with our professional assessment.

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.

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.

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.

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.

Sewer Line Repair

Sewer line problems cause backups, odors, and potential health hazards. Our plumbers use video cameras to inspect the line, identify the damage, and repair or reline the pipe — often without full excavation.

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.

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.

Frequently Asked Questions

Answers to the most frequently asked plumbing questions from Alton homeowners.

What plumbing emergencies require immediate service in Alton?

Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in Alton. A burst pipe can release hundreds of gallons per hour, and gas leaks pose fire and explosion risks. Magnet Plumbing provides 24/7 emergency plumbing service throughout Alton and surrounding New Hampshire communities.

How long does a plumbing repair take in Alton, NH?

Simple repairs like faucet replacement, toilet repair, or drain clearing in Alton often take 1 to 2 hours. More complex jobs like slab leak repair, water line replacement, or water heater installation typically take a half to a full day. Whole-home repiping can take 2 to 4 days. Magnet Plumbing provides a clear time estimate before starting any job.

How do I shut off my water in a plumbing emergency in Alton?

Your main water shutoff valve in Alton is typically located near the water meter, near the front foundation, or in the basement or utility room. Turn the valve clockwise to close it. If you cannot find your shutoff or it is stuck, call Magnet Plumbing immediately — our emergency crew can help locate and operate the valve to stop water damage.

How do I prevent frozen pipes in Alton, NH?

To prevent frozen pipes in Alton, 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 can I tell if I have a slab leak in my Alton home?

Signs of a slab leak in Alton 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.

How often should I have my drains cleaned in Alton?

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