Our Plumbing Services in Cornwall

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

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.

Gas Leak Detection

Professional gas leak detection using calibrated detectors and pressure testing to find leaks in gas lines, connections, appliances, and meters. We locate the leak source precisely and recommend repairs immediately.

Drain Cleaning

Clogged drains slow your life down. Our licensed plumbers clear kitchen drains, bathroom drains, main sewer lines, and floor drains using professional hydro-jetting equipment that cleans the entire pipe interior.

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.

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.

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.

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.

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.

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.

Water Heater Replacement

When your water heater reaches the end of its life, we make replacement easy. Our plumbers handle everything — disconnection, removal, installation, and final testing — so you have reliable hot water again fast.

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.

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.

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.

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.

Grease Trap Cleaning

Professional grease trap cleaning for commercial kitchens of all sizes. Reliable schedules, full compliance paperwork, and a clean trap every time — keeping your operation running and inspection-ready.

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

Protect your basement before the next storm. Our plumbers install sump pumps with float switches, check valves, and battery backup systems — ready to keep groundwater out of your home reliably.

Pipe Repair

Expert pipe repair for residential and commercial properties. We locate leaks and damage accurately, perform durable repairs, and pressure test the system to confirm everything holds before leaving.

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.

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.

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.

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.

Gas Line Repair

Gas line leaks demand immediate professional attention. Our licensed plumbers diagnose and repair gas line failures safely, using proper materials and testing to ensure your gas system is secure and code-compliant.

Sewer Camera Inspection

Professional sewer camera inspection to diagnose blockages, root intrusion, cracks, offsets, and collapse. We show you the video so you can see the problem and make informed decisions about repairs.

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.

Frequently Asked Questions

Have questions about plumbing in Cornwall? We have answers.

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

Trenchless sewer repair in Cornwall 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 Cornwall home?

Signs of a slab leak in Cornwall 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 do I shut off my water in a plumbing emergency in Cornwall?

Your main water shutoff valve in Cornwall 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.

Does homeowners insurance cover plumbing repairs in Cornwall, NY?

In Cornwall, homeowners insurance typically covers sudden and accidental plumbing damage such as a burst pipe flooding your home. The cost of repairing the pipe itself may not be covered, but the resulting water damage often is. Gradual leaks and corrosion from neglected maintenance are usually excluded. Call (844) 618-0753 if you need documentation for a claim.

How much does a plumber cost in Cornwall, NY?

Plumber rates in Cornwall 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 Cornwall homes?

Low water pressure in Cornwall 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 Cornwall properties can also restrict flow significantly. A licensed plumber can diagnose the specific cause and recommend the right fix.

"They are the best. They come when they say they will, fair pricing, are attentive to detail, protect the floors, are friendly and professional. Very different from plumbers we have used in the past. Thank you Saul!"

— Baxter B.
★★★★★

"We noticed our water bill doubling month over month and could not find anything visible. These guys came out with the leak detection equipment and located a slab leak under the living room in about thirty minutes. The repair was minimally invasive — small access cut, patched afterward, and the bill is back to normal. Really impressed with the professionalism."

— Derek M.
