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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

Annual backflow testing and prevention device installation for residential and commercial properties. Our certified testers verify your backflow preventer and handle compliance paperwork with your water authority.

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.

Frequently Asked Questions

Have questions about plumbing in Southold? We have answers.

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

Your main water shutoff valve in Southold 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.

What should I do if I smell gas in my Southold home?

If you smell gas in your Southold 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.

How do I prevent frozen pipes in Southold, NY?

To prevent frozen pipes in Southold, 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 much does a plumber cost in Southold, NY?

Plumber rates in Southold 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 is trenchless sewer repair and is it right for my Southold home?

Trenchless sewer repair in Southold 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 often should I have my drains cleaned in Southold?

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

"Installed a new sump pump in our basement before hurricane season and I am so glad I did. The install was clean, the pump runs quietly, and they explained the battery backup option clearly. Great experience."

★★★★★

"Had a new tankless water heater installed and could not be happier. The plumbers were punctual, clean, and walked me through the warranty and maintenance before leaving. Highly recommend for any water heater project."

— Anthony R.
★★★★★

"My hot water was not working so they replaced and adjusted the regulator valve, then repaired the shower diverter and replaced the hot and cold valves. Now I can easily have hot water and it feels like a new shower again. They even picked up the parts I had ordered in Hollywood at Ferguson Plumbing Supply."

— Frederick H.
