General Contracting On Long Island

Because renovation projects mostly fail at the joins rather than at the tasks. There are two: the rough-in, where plumbing, gas and heating have to be in the wall and inspected before it closes, and the making-good afterward, where somebody has to finish what was opened. Split across three companies, both of those sit between schedules and between invoices, and the job stops while nobody is doing anything wrong. We are not claiming to frame faster than a specialist framer. We are saying the handovers disappear when it is one licensed team.

We are, and it is worth asking any contractor that question before you sign. When the mechanical work and the building work are separate contracts, the making-good tends to belong to whoever is cheapest to blame, and the room stays unfinished while that gets argued. Because the plumbing, gas, HVAC and the building are all our own team, closing and finishing is part of the same job rather than a separate negotiation.

We handle the application and see the inspections through as part of the job. The useful thing to understand up front is that a renovation is not one approval — it is a sequence, and the mechanical work is generally inspected before the surfaces that hide it. That order is what decides whether a hold-up costs a day or a fortnight, which is why it is worth talking through before scope is fixed rather than halfway in.

Yes, on both counts, and it is better established at the quote. An incorporated village such as Babylon Village runs its own building department and the Town has no jurisdiction inside its lines, so the filing goes somewhere different. A property in a mapped flood zone brings the flood damage prevention rules into play, and those apply to replacement mechanical equipment rather than only to new — which can turn a straightforward relocation into a design question. Our Babylon Village and Massapequa pages go into the specifics. Tell us the address and we will factor it in.

Yes. We take on the plumbing, gas and HVAC on somebody else's project regularly, and there is no requirement to use us for everything. If you are already committed to a builder you trust, the thing worth agreeing early is which of us owns the rough-in schedule and who closes the wall afterward, because those are the two seams where the delays live.

Because that is where renovations fall apart. When the plumber, the HVAC company and the contractor work for three different firms, nobody owns the sequence, and the delays land on you. NJM holds all of it — Master Plumber, TASK 86/87 gas certification and general contracting — so there is one schedule and one company accountable.

It is handled as part of the job rather than handed to you as a form. The useful thing to understand up front is that a renovation is not one approval — it is a sequence, and the mechanical work is generally inspected before the surfaces that hide it. That order is what decides whether a hold-up costs a day or a fortnight. Jurisdiction matters too: an incorporated village such as Babylon Village or Lindenhurst runs its own building department and the Town has no say inside its lines, so tell us the address and we will tell you which department the job answers to.

For a lot of Long Island Capes and ranches, a dormer is the most cost-effective way to add real living space, because it uses the footprint and the foundation you already have. Whether it is right for your house depends on the roof structure, the layout below and what the local code allows — we will look and tell you straight.

It depends on the scope, the condition of what is behind the walls and lead times on materials. We will give you a realistic schedule after seeing the space rather than a number designed to win the job. What we can say is that having the plumbing and gas in-house removes the delays that usually come from waiting on another trade.

Yes — that is the whole point of NJM. Plumbing, heating, cooling and gas are all handled by our own licensed team, not subcontracted. It is why a renovation with us runs on one schedule.

Yes. We handle contracting work for Long Island businesses alongside our commercial plumbing and HVAC, scheduled around trading hours where possible.

Yes. This is the kind of job most people are not expecting to pay for all at once, particularly when the old one has just failed. Financing lets the work happen when it needs to rather than when the savings catch up. We finance through Synchrony, subject to credit approval. Ask when you call and we will go through the options for your job.

All of Nassau County and all of Suffolk County, from our base in North Babylon. That covers Babylon, West Babylon, Lindenhurst and Deer Park on our doorstep, west to Massapequa, Farmingdale and Hicksville, north to Commack and Dix Hills — and the towns in between we have not named here. Call 631-587-0085 if you are not sure whether you are in range.

Yes, free and with no obligation. For contracting work we will want to see the space before quoting, because a renovation estimate given without looking is a guess. Send the form and we will be in touch within 24 hours to arrange it.
