24/7 Emergency Service
Someone answers, every hour of every day. Ten minutes from the village. If a storm has put water where the boiler is, that is the call we are set up to take.
Babylon Village is an incorporated village with its own building department, and older waterfront housing that brings its own plumbing problems. We work here constantly — the shop is ten minutes north.

631-587-0085WE ANSWER EVERY CALLBabylon Village is incorporated, and that single fact governs most of what follows. The Village runs its own Building Department at 153 West Main Street, and the Town of Babylon has no jurisdiction inside village lines — so a contractor who works mostly in the surrounding hamlets is filing with the wrong department. We are ten minutes north in North Babylon and work on both sides of that line.
The second fact is the water. The Village sits on the Great South Bay, its waterfront is densely built and largely residential, and the Village describes itself as having many areas of high groundwater with roadways close to sea level. That is why the flood code below is not a formality here. It is frequently the thing that decides where your new boiler is allowed to go.

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.
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.
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.
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.
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.
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.
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.
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.
If your property sits in a mapped flood zone, Village Code Chapter 171 is not advisory. It states that new and replacement electrical equipment, heating, ventilating, air conditioning, plumbing connections and other service equipment must be located at or above the base flood elevation, or else be designed to prevent water entering and accumulating within the components during a flood and to resist hydrostatic and hydrodynamic loads. The word that catches people is replacement. Swapping a failed boiler for an identical one in the same spot is not automatically permitted work.
The Village also goes beyond the federal minimum on the structure itself. In the mapped AE and AH zones, new construction and substantial improvements must have the lowest floor — and Chapter 171 defines lowest floor to include the basement or cellar — elevated to two feet above base flood elevation. In an unnumbered A zone with no published elevation data, the requirement is three feet above the highest adjacent grade instead.
And there is the substantial improvement test. Once the cost of the work reaches fifty per cent of the market value of the structure before the work starts, the whole building is brought up to current standards, not just the part you were replacing. That is what turns a large renovation into a much larger one, and it is far better understood at the quoting stage than discovered halfway through.
In practice this means a boiler, water heater, furnace, air handler or condenser going back into a basement that has flooded before is often not a legal replacement, and a job that looked like a straight swap becomes a relocation. Tell us the address when you call and we will factor it in before anyone orders equipment.

Someone answers, every hour of every day. Ten minutes from the village. If a storm has put water where the boiler is, that is the call we are set up to take.
Moving a boiler, water heater or air handler up out of harm and into compliance, including the plumbing, gas and venting changes that come with the move. This is the most common flood-zone job in the village and the one most often quoted wrong by someone who has not read Chapter 171.
Replacement and repair across a village that was substantially built out by the mid-1970s, which means most original equipment has already been changed at least once. Tankless included — we are Navien NSS certified.
Worth knowing before you start: Village Code requires a permit for the initial installation of an oil burner and its tank, and separately requires one for the replacement of a fuel oil tank connected to an existing burner. A tank swap is permitted work here even when the burner stays.
TASK 86/87 certified gas work. One village-specific rule catches people out: Village Code requires the grounding of CSST gas piping to be performed by a licensed electrician and acknowledged on the electrical underwriter certificate. We coordinate that rather than leaving you to discover it at inspection.
Full systems where the house supports ductwork, and ductless mini-splits where running ducts would mean opening up finished space — which in older village housing is usually the better answer anyway. Condenser siting gets the flood elevation treatment along with everything else.
Village housing has generally been renovated in layers over decades, so what is behind the wall is rarely what the last owner described. We trace leaks properly before opening finishes, and price from what is actually there.
The entire village is served by Suffolk County Sewer District No. 3, so this is sewer work rather than cesspool work. In the flood zone, Chapter 171 requires automatic backflow valves on sanitary sewage systems — the thing that stops the bay arriving through the fixtures.
Kitchens, bathrooms and additions with the plumbing and HVAC handled by the same licensed team that does the building. On any substantial project in a flood zone the fifty per cent test needs answering before scope is fixed.
What it says on the coupon is what comes off the bill. Mention it when you call.
The Village, not the Town. Babylon Village is incorporated and runs its own Building Department at 153 West Main Street, which enforces the New York State Building and Fire Codes plus Village zoning inside village lines. The Town of Babylon has no jurisdiction there. Work in a mapped flood zone additionally needs a floodplain development permit, which is a separate application from the building permit.
Because Village Code Chapter 171 applies to replacement equipment, not just new. It requires new and replacement heating, ventilating, air conditioning, electrical and plumbing service equipment in a mapped flood zone to be at or above base flood elevation, or designed to keep water out entirely and resist flood loads. A basement that has flooded before is usually below that line. It turns a swap into a relocation, which is much cheaper to plan for at the quote than to discover on installation day.
For the structure, Chapter 171 requires the lowest floor — explicitly including the basement or cellar — to be two feet above base flood elevation in the mapped AE and AH zones. In an unnumbered A zone where no base flood elevation has been published, it is three feet above the highest adjacent grade. For service equipment specifically, the requirement is at or above base flood elevation. You may see a reference elsewhere to three feet of freeboard; the codified text says two, and the Building Department on 631-669-1300 is the place to settle it for your address.
Chapter 171 defines it as any reconstruction, rehabilitation, addition or other improvement whose cost equals or exceeds fifty per cent of the market value of the structure before the work starts. Past that threshold the flood damage prevention standards apply to the whole building rather than only the part you were changing. It catches people out on larger renovations, and it is worth knowing before you commit to scope rather than after.
The Village adopted the FEMA Flood Insurance Rate Map panels effective 25 September 2009, and copies are on file at the Village Clerk office. For your specific address, the FEMA Map Service Center is the authoritative lookup — we will not guess a zone for you, because the answer changes what the job is. Tell us what it says when you call and we will quote against it.
Public sewer. The entire village is served by Suffolk County Sewer District No. 3, the Southwest district, which is a real difference from most of the surrounding hamlets in the Town of Babylon — several of those are still on cesspools and septic systems and are only now being studied for connection. It means a drain problem in the village is a drain problem, not a cesspool problem.
Yes. Village Code requires a permit for the initial installation of an oil burner and the fuel oil tank connected to it, and separately requires a permit for the replacement of a fuel oil tank connected to an existing burner. People are often surprised by the second one, because the burner is not being touched.
Regularly, and they are the reason this page is written the way it is. Most of the village was densely developed by the mid-1970s and the housing has been renovated in layers since, so what is behind the finishes is rarely what anyone expects. On the waterfront, add the flood code, high groundwater and salt air on outdoor equipment. We price from what we find rather than from an assumption.
Usually, yes. Ductless mini-splits heat and cool individual rooms with no ductwork at all, which is why they suit older village homes where running ducts would mean opening up finished space. One outdoor unit can serve several indoor heads. In a flood zone the outdoor unit still has to meet the elevation rule, so siting gets designed rather than assumed.
Both. Homes, and the shops and restaurants along the village commercial strip. Commercial work gets the same licensed crew. Note that the flood code has its own nonresidential standards — in the coastal high hazard zones, floodproofing is explicitly not an allowable alternative to elevating.
