Water and drain service
Plumbing repair and maintenance in NYC
A leaky faucet, a clogged drain, a toilet that will not stop running. Small problems waste water and turn into bigger ones. Our plumbers fix them in Brooklyn, Queens, Staten Island and Manhattan, usually in a single visit.
Everyday plumbing we fix
Not every call is an emergency. These are the repairs that keep a home or building running properly.
Leaky faucets and showers
Worn washers, O-rings and cartridges replaced, or the fixture replaced if the body is corroded.
Clogged sinks, tubs and showers
Cleared by snake or hydro-jet. Repeat clogs get a camera check of the branch line.
Running or weak-flushing toilets
Flappers, fill valves and flush valves replaced; wax rings reset when a toilet rocks or smells.
Shutoff valves that leak or will not close
Old multi-turn valves swapped for quarter-turn valves so you can stop water fast in an emergency.
Leaking pipes and fittings
Supply lines, drain fittings and traps under sinks repaired or replaced.
Low water pressure
Clogged aerators and cartridges, failing pressure-reducing valves and old galvanized supply lines.
Noisy pipes
Loose pipe straps secured and water hammer arrestors installed.
Fixture installation
New faucets, toilets, garbage disposals and dishwasher connections.
Catch problems before they cost you
A slow drip under a sink can rot a cabinet floor and leak into the apartment below. A running toilet can waste hundreds of gallons a day. A shutoff valve that will not close turns a small leak into a flood.
A plumbing check finds these early. It is especially useful when you buy a home, take over a building, or before renting out a unit.

Plumbing repair questions
Do you provide plumbing and heating maintenance service?
Yes. GW Mechanical Corp offers one-time maintenance visits and annual maintenance plans for homes, apartment buildings and restaurants in Brooklyn, Queens, Staten Island and Manhattan. A visit covers the water heater, boiler, expansion tank, fixtures, drains and shutoff valves, with a written report and photos. Plan members get a scheduled fall visit and priority dispatch in winter.
Does maintenance really extend the life of a boiler, water heater or expansion tank?
Yes, measurably. A boiler that is cleaned and combustion-tested every year commonly reaches 20 to 25 years; one that is never serviced often fails at 12 to 15. A tank water heater that is flushed yearly and has its anode rod checked reaches its 10 to 12 year design life instead of failing at 6 or 7. An expansion tank is checked for correct air charge each visit and replaced when waterlogged, which protects the boiler, the water heater and the relief valve from pressure damage. Clearing scale and sediment also keeps water flow and pressure where they should be.
What can I do before winter to reduce the risk of heating equipment failure?
Have the boiler serviced before October 1: burners cleaned, combustion tested, safety controls tested, expansion tank and system pressure checked, and on steam boilers the low-water cutoff flushed and vents checked. Replace thermostat and carbon monoxide alarm batteries. Flush the water heater and test its relief valve. Bleed radiators, insulate pipes in unheated spaces, shut off and drain outdoor spigots, and clear the vent terminations outside. Our winter heating maintenance checklist walks through every step.
Do you fix small plumbing problems like a leaky faucet?
Yes. Dripping faucets, running toilets, clogged sinks and tubs, leaking shutoff valves and noisy pipes are everyday work for us in Brooklyn, Queens, Staten Island and Manhattan.
How much water does a dripping faucet waste?
A faucet dripping once a second wastes thousands of gallons a year. In a multi-unit building, a few dripping faucets and running toilets add up on the water bill quickly.
Should I use chemical drain cleaner?
We recommend against it, especially on older cast-iron and galvanized pipes common in NYC. It can damage the pipe and makes the job hazardous for the plumber. A plunger or plastic drain snake is safer for a first try.
Can you check the plumbing in my whole house or building?
Yes. A plumbing check covers fixtures, shutoff valves, visible supply and drain piping, the water heater and signs of leaks, with a written list of what needs attention.
Do you work in apartments in co-ops and condos?
Yes. We follow building work hours and provide certificates of insurance when the managing agent requires them.
