Your Local Plumber, Heating & Cooling Company In North Babylon
NJM Mechanical & Contracting has been based at 31 Magro Drive in North Babylon since 2004. That is not a service-area claim on a map — it is where the trucks are parked overnight, which is why a call from a North Babylon street gets answered faster than one from the far end of the county.
North Babylon is a hamlet of roughly seventeen and a half thousand people inside the Town of Babylon, and most of it was built in the post-war boom. Houses of that vintage share a set of problems: original galvanized supply lines narrowing with corrosion, cast iron waste stacks reaching the end of their service life, boilers and furnaces well past the age where a replacement pays for itself in fuel. We work on these houses every week.

Before you call
Two kinds of visit. You’ll know which before we come.
We don’t charge to quote a job. We do charge to find a problem nobody has identified yet. Which one you need — and what it costs — gets agreed on the phone, so nothing about the cost is a surprise on the doorstep.
The rate you are told is the rate
You get the number on the phone, before anyone is dispatched, and it is what you are charged when the technician arrives. One rate across all four trades — plumbing, heating, cooling and gas.
What it pays for
A licensed, insured technician carrying the certifications the work needs, and the time to find what has actually failed — not a quick look and a guess.
Watch for the bait and switch
A call-out advertised at almost nothing gets recovered once someone is standing in your basement. Get the number before anyone travels — from us, or from anyone else you call — and hold them to it when they arrive.
Financing on larger jobs
A boiler that fails in January is not a purchase anyone planned. Financing is available on the big-ticket work, so a system replacement does not have to come out of savings in one go.
What it is normally used for
Boiler, furnace and water heater replacement, a full air conditioning system, a whole-house repipe, sewer and water main work, and larger contracting jobs — kitchens, bathrooms, dormers and extensions.
When to bring it up
At the estimate, before anything is scheduled. It is worth asking even if you think you will not need it, because knowing it is there changes what you are willing to consider fixing properly.
What it does not change
The price of the job. The quote is the quote whether you finance it or not — and on a straightforward repair it is usually not worth the paperwork. We will tell you which one you are looking at.

What We Do Here
Every Trade, One Local Team
Repipes & Supply Line Replacement
Original galvanized lines in post-war houses eventually restrict to the point where pressure drops and water discolors. Replacing them is one of the most common jobs we do in this hamlet.
Boiler & Furnace Replacement
Heating systems in houses of this age are frequently the original equipment or its first replacement. Gas, oil and high-efficiency, installed with permits pulled through the Town of Babylon.
Air Conditioning
Central air installation and repair, plus ductless mini-splits for the converted attics and additions that Capes and ranches around here tend to acquire.
Gas Lines & Inspections
TASK 86/87 certified gas work — new lines for ranges, dryers, generators and heating equipment, plus inspections and code compliance.
Dormers & Additions
The standard way to get real space out of a North Babylon Cape. We design, permit and build, with the plumbing and heating for the new space handled in-house.
Kitchen & Bathroom Renovations
Full renovations where the gas, water and waste are handled by our own Master Plumber-led crew rather than a subcontractor.
Commercial Service
Plumbing and HVAC for North Babylon businesses, scheduled around your trading hours where we can.

Common Questions
Frequently Asked Questions
Where exactly are you based?
31 Magro Drive, North Babylon, NY 11703. We have operated from here since 2004, which makes North Babylon the shortest drive we make and usually the fastest response we give.
Who issues building permits in North Babylon?
North Babylon is a hamlet rather than an incorporated village, so permits go through the Town of Babylon. We pull them as part of the job and see the inspection through — no separate application for you to chase.
What plumbing problems are common in North Babylon houses?
Most of the housing stock here went up after the war, so we see a lot of the same things: galvanized supply lines corroding closed, which shows up as low pressure and discolored water; cast iron waste stacks failing; and heating equipment at or past the end of its service life. None of it is unusual for houses of this age.
Do you handle emergencies overnight?
Yes, 24 hours a day, every day of the year. Call 631-587-0085. Regular office hours are Monday through Friday 7:00 AM to 6:00 PM and Saturday 7:00 AM to 5:00 PM.
Do you do all four trades, or just plumbing?
All four. Plumbing, heating, cooling, gas and general contracting, all with our own licensed team. That matters most on renovation work, where hiring three separate companies is where projects normally fall apart.
Are estimates free?
Yes, free and with no obligation. Call 631-587-0085, or use the form on this page and we will be in touch within 24 hours.
