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

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.

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 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 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.

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.

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.
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.
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.
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.

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 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 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 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.

Have questions about plumbing in Cornwall? We have answers.
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.
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.
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.
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.
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.
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.
Honest feedback from homeowners who trusted Magnet Plumbing with their plumbing projects.
"Replaced a corroded outdoor hose bib and a leaky kitchen faucet. In and out in under an hour. Professional work, fair price."
"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!"
"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."
