Plumbing, Heating & Cooling In Hicksville

More than half of Hicksville went up in the 1950s, and the water district is currently replacing distribution mains of exactly that age. The supply piping inside a house of the same vintage is at the same point in its life.

Plumbing, Heating & Cooling In Hicksville

Hicksville is a hamlet in the Town of Oyster Bay, and it is one of the purest examples of the post-war boom on Long Island. The population went from around eight thousand in 1950 to nearly fifty thousand by 1959, built straight onto former potato farms. Of the roughly thirteen and a half thousand housing units here, more than fifty-seven per cent went up in the 1950s alone, and the median house was built in 1955 — Capes, ranches and split-levels, eighty-five per cent of them owner-occupied.

That single decade of construction is why so much in Hicksville needs attention at the same time. The water district is currently running a phased replacement of distribution mains that date to the 1950s — one phase alone covered around fourteen thousand feet of main, twenty-five hydrants and three hundred and twenty service connections. The supply piping inside a house of the same vintage is at precisely the same point in its life.

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.

Estimate visitNo charge

You already know what you want done

A boiler replaced, a bathroom rebuilt, a gas line run. We come out, look at the job and give you a number.

No obligation
Diagnostic visitQuoted on the call

Something has failed and nobody knows why

A licensed technician and the time to find what has actually gone wrong. One rate across plumbing, heating, cooling and gas, and one number to reach us on — there is no separate line to find at midnight. You get the figure before anyone is dispatched, and after-hours, weekend and holiday work is quoted the same way.

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.

Where To Start

When Three Things Are All Near The End At Once

A hamlet built in one decade reaches the end of things in one decade. The useful question in a Hicksville house is rarely what is wrong — it is what to do first.

Somebody calls about the boiler, and while we are down there the supply piping is visibly on its last years and the water heater is past its warranty. All three are true at once, and that is not bad luck. It is what happens when a house is seventy years old and everything in it was installed in the same month.

What we will not do is quote you all three and let you work it out. There is an order, and it is mostly decided by what fails badly rather than what fails first. A water heater that goes takes out a floor. A supply line that goes takes out a ceiling. A boiler that dies in January is a bad week but it is a contained one, and a good technician can usually keep an old one running one more season while you plan properly.

So the honest sequence is normally: anything that will cause water damage when it goes, then anything that is costing you real money every month it runs, then the thing that is merely old. Occasionally the answer is to do two together because the labour overlaps and doing them separately means paying twice to open the same wall — and we will say so when it is true, because that is the version that saves you money rather than the version that bills more.

The reason to have that conversation with one company is that in a house like this the trades do not stay in their lanes. A boiler replacement turns into gas work and sometimes venting. A repipe turns into drywall. Kitchens and bathrooms are all four trades at once. When it is one licensed team you get one sequence and one company accountable for it, instead of three quotes that each assume the others go first.

Quick Rules Of Thumb

  • First: anything that floods a room when it fails
  • Then: anything costing you money every month it keeps running
  • Last: the thing that is simply old but behaving
  • Two jobs at once when the labour genuinely overlaps, not to pad the bill
  • One team means one sequence, not three quotes that contradict each other

What We Do Here

Services In Hicksville

Water Services & Repipes

New and replacement service lines to district specification, and whole-house repipes where the original supply has closed up or started weeping at the joints.

Backflow Prevention

Hicksville Water District requires an RPZ or double-check assembly after the meter on new residential services, and annual testing by a state-certified tester. Irrigation systems need their own device.

Water Heaters & Tankless

Replacement, installation and repair, including high-efficiency tankless. Navien NSS certified for the units that need more than a reset.

Boilers & Furnaces

Heating plant in a 1950s Hicksville house is on its second or third generation. We install and service both, and we say plainly when a repair has stopped making sense.

Central Air & Ductless

Full systems and ductless mini-splits — the practical answer in a Cape or a split-level with no duct chase.

Gas Lines & Inspections

TASK 86/87 certified gas work. Oyster Bay requires a permit for heating furnace or burner installation and for fuel storage tanks, as well as for the piping itself.

Commercial Plumbing & HVAC

Hicksville has a substantial commercial base along Broadway and the 106 and 107 corridor, and a downtown being rebuilt around the LIRR station. Retail, offices and food service, with emergency cover for the failures that would close you.

24/7 Emergency Service

Every day of the year, residential and commercial, one number for all four trades.

Common Questions

Frequently Asked Questions

Everything in my house is the same age. What should I do first?

Whatever will cause the most damage when it fails, rather than whatever is oldest. A water heater or a supply line lets go and you are drying out a room. A boiler dies and you are cold for a few days, which is miserable but contained — and an old one can often be nursed through one more season while you plan the replacement properly. We will give you that order honestly, including the parts that say wait, because a house built in 1955 has a queue and pretending otherwise just means you spend the money in the wrong sequence.

Is it cheaper to do two jobs at the same time?

Sometimes genuinely, sometimes not, and it depends entirely on whether the labour overlaps. If two jobs mean opening the same wall or draining the same system, doing them together saves you a second lot of access and making-good. If they are in different parts of the house they cost the same either way and there is no reason to bundle them. We will tell you which one you are looking at rather than assuming bigger is better for you.

Can you do the air conditioning as well as the heating?

Yes, and in a 1950s Hicksville house the cooling question is often the more interesting one. A lot of these houses have no ductwork worth the name, or ducts that were sized for heating and never for cooling, which is why rooms at the end of a run never get comfortable. Ductless mini-splits solve that without tearing up finished space, and one outdoor unit can carry several rooms. We install both and we will tell you which suits the house.

Do you do kitchens and bathrooms here, or only the mechanical work?

Both, and on a house of this age that matters more than it sounds. A 1950s bathroom renovation is plumbing, gas, venting and building work at once, and the usual way these go wrong is the handover between trades rather than any of the work itself. Because the plumbing, heating, cooling and the building are all our own licensed team, there is one schedule and one company accountable rather than three contractors waiting on each other.

Who issues plumbing permits in Hicksville?

The Town of Oyster Bay Building Division, part of the Department of Planning and Development. Hicksville is an unincorporated hamlet, so there is no separate village department. Permits are required for plumbing fixtures, sewer connections, drainage work, fuel storage tanks, heating furnace or burner installation, fire sprinklers and underground irrigation. Straight repairs and like-for-like fixture swaps generally are not.

What does the water district require for a new water service?

The Hicksville Water District ordinances are specific. One-inch and two-inch service lines must be Type K copper from the main to the curb stop, four inches and larger must be ductile iron, and the minimum bury depth is four feet six inches. An inverted-key curb cock in an iron curb box is required between the property line and the curb line. Only District employees may tap the main. New residential services need an RPZ or double-check backflow assembly after the meter, tested annually by a state-certified tester.

Is the tap water in Hicksville safe?

The district reports its water as meeting New York State standards. Groundwater across this part of Nassau County does have documented contamination — 1,4-dioxane and PFAS among them, and there are two federal Superfund sites in the area — and the Hicksville Water District has responded by taking affected wells offline and building advanced oxidation and granular activated carbon treatment, a programme expected to cost more than seventy million dollars. The district publishes an annual water quality report; that is the place to read the current numbers for your own supply, rather than taking anyone selling filtration at their word.

Do you handle commercial work in Hicksville?

Yes. Offices, retail and food service along Broadway and the Route 106 and 107 corridor, and the newer mixed-use development around the LIRR station. Same licensed crew, same 24/7 response, scheduled around trading hours where the job allows.

Do I need a backflow preventer on my sprinkler system?

Yes. The district requires permission before an underground irrigation system is installed, along with a backflow device that is tested annually, a programmable timer and a rain or soil-moisture sensor. There are also watering restrictions — odd and even days, and nothing between ten in the morning and four in the afternoon.

About seventeen miles from 31 Magro Drive in North Babylon. Further than our Babylon-town work, and we cover it — call 631-587-0085 and we will be straight with you about scheduling.
