Old tank leaking from the bottom? Always running out of hot water? We size, install, and permit tank and tankless water heaters across Hempstead, with hot water back the same day.
Tank, tankless & hybridAll major brandsPermit pulled with the TownSame-day install
When a Hempstead water heater hits ten to twelve years old, has a rusty leak at the bottom, or simply cannot keep up with the household, replacement is the right move. Most hot water heater replacement jobs we run finish in a single day, with hot water back before dinner and the old tank hauled out of the basement before the truck leaves.
We help Hempstead homeowners pick the right unit for their actual hot-water demand and venting situation: a 40 gallon water heater install or 50 gallon water heater install for traditional tank service, a Navien tankless water heater for endless hot water and reclaimed closet space, a Rinnai tankless water heater for whole-house performance, or a hybrid heat-pump unit for the lowest operating cost. We are an installer for the major brands, so the longest manufacturer warranty available is the one you get.
Every quote includes the unit, the new water heater expansion tank, code-required gas piping or electrical work, an updated drain pan and condensate line, hauling away the old tank, and a permit pulled with the Town of Hempstead when required. Pricing is flat-rate and quoted on the call before any work starts.
When to Replace
Three Signs the Old Unit Is Done
Replacement is the right move once one of these shows up. We can usually tell from a phone description and a photo, before the trip charge.
Leaking from the Tank
A puddle around the base of the tank, water staining on the jacket, or rust at the bottom seam means the inner liner has rusted through and cannot be repaired. The water has to be shut off before it dumps the whole tank into the basement. Replacement is the only fix.
Over 12 Years Old
Standard tank water heaters last 10 to 12 years. If yours is over that age and starting to need repairs, throwing money at parts almost always costs more than replacing the unit. The new tank also runs more efficiently, so you get the install cost back over its lifespan.
Repair Costs Half of Replacement
Rule of thumb: if the quoted repair is more than half the cost of a new unit, replace. A new gas valve, heat exchanger, or full element-and-thermostat overhaul on an older tank usually crosses that line. We give you both numbers on the spot so you can decide.
If your unit is under eight years old, has plenty of life left, and the repair is under a third of replacement, we will tell you that on the call and quote a repair instead. We do not push replacements for the sake of replacements.
What We Install
Tank or Tankless, Sized to Your House
The biggest decision is tank versus tankless. Both have a place in Hempstead homes; the right answer depends on your hot-water demand, fuel type, and how much closet space you want back.
Tank40 / 50 / 75 Gallon
Lower up-front cost, simple install. Gas, electric, and hybrid heat-pump units. Right answer for most one and two-bath Hempstead homes, especially when the existing utility closet was built around a tank. Hybrid heat-pump units cost more up front but cut the operating cost roughly in half.
TanklessNavien · Rinnai
Endless hot water, reclaimed closet space. Wall-hung condensing units, 18 to 20 year lifespan, and no tank to leak. Higher install cost because of stainless venting and gas-line resizing, but the right move for larger households, second-bathroom additions, and homeowners replacing the tank for the second or third time.
Our tankless water heater installation includes properly sized stainless venting, gas-line resizing where needed, and a flush kit pre-plumbed so future tankless water heater maintenance is easy. The cost of tankless water heater installation in Hempstead runs higher than a tank swap because of the venting and gas work, but the unit lasts roughly twice as long and uses less energy.
If you are unsure, call us with your fuel type, the current tank size, the number of bathrooms, and a photo of the existing closet. We can usually scope a recommendation in five minutes on the phone.
What's Included
A Real Replacement Quote, Not Just a Tank
The unit and the parts around it
The new water heater itself, the expansion tank, code-required gas piping or electrical work, an updated drain pan, a fresh T&P valve, condensate line on condensing units, and new flexible connectors. The price you see is the price for everything that makes the unit run.
Permit with the Town of Hempstead
Water heater replacements in Nassau County require a plumbing permit. We pull it on your behalf, schedule the inspection, and stay on the hook until the inspector signs off. Saves you the hassle and protects the home sale paperwork later.
Manufacturer warranty registered for you
We are factory-installers for the brands we carry. Your manufacturer warranty registration happens the day of install, so you get the longest available warranty (often 6 to 12 years on tank, 12 to 15 on tankless) without having to send in a card.
Old unit hauled away, area left clean
We drain the old tank, walk it out, and dispose of it properly. The closet floor is swept, drop cloths come up, and you do not have a 150 pound steel tank sitting on the curb waiting for sanitation pickup.
How It Works
Four Steps to a New Water Heater
Most replacements are scheduled, finished, and inspected within a few days of the first call. Here is what that actually looks like.
1
Phone consultation and quote
Call with your current tank size, fuel type, brand, and a photo of the closet. We size the right replacement and give you a flat-rate quote on the call. No trip charge for a quote you are still deciding on.
2
Permit pulled, install scheduled
Once you approve the quote, we pull the Town of Hempstead permit and schedule the install for the next available day. Most replacements happen within 24 to 72 hours of the call.
3
Same-day install
The truck arrives with the new unit, expansion tank, fittings, and tools. We shut off water and gas, drain and remove the old tank, set the new one, run new connections, fire it up, and verify temperature and pressure. You have hot water again before we leave.
4
Inspection and sign-off
The town inspector comes out within a week or two to verify the install. We meet them on site, walk through the work, and get the permit signed off. You get a copy of the closed permit for your records.
Units We Install
Every Common Replacement in Hempstead
From a straight 50 gallon swap to a full tankless conversion, here are the replacements we run most often.
40 Gallon Tank
The standard for one and two-bedroom Hempstead homes and apartments. Available in gas and electric. Most 40 gallon water heater installs are same-day, in and out before dinner.
50 Gallon Tank
The most common Hempstead replacement. Right size for three-bedroom homes with two and a half baths. Gas, electric, and high-recovery models available. Standard 6 to 12 year manufacturer warranty.
75 Gallon Tank
For larger homes, big families, or houses with multiple bath additions. Higher BTU input means faster recovery between showers. Worth it when the existing 50 has been running short for years.
Navien Tankless
Wall-hung condensing tankless water heater. Endless hot water, 95% efficiency, and a 15 year heat-exchanger warranty. Right answer for whole-house performance and reclaiming closet space.
Rinnai Tankless
Compact wall-hung tankless. Strong dealer network and parts availability on Long Island. Indoor and outdoor venting options for tight closets and exterior installs.
Hybrid Heat Pump
Tank-style unit with a heat pump on top. Cuts hot-water operating cost roughly in half versus straight electric. Higher up-front cost, but the cheapest unit to run over a 12 year life.
Expansion Tank
Required by Nassau County code on most newer water heater installs. Absorbs the pressure spike when water heats and expands. We install one with every replacement.
Tankless Conversion
Replacing an old tank with a tankless unit. Includes new stainless venting, gas-line resizing, mounting bracket, and isolation valves for future descaling. Bigger project, longer life.
Old Unit Removal
Drain, disconnect, walk out, and dispose of the old tank. Included in every replacement quote. We do not leave it on the curb for sanitation; we take it with the truck.
Tank Already Leaking?
Call. We diagnose on the phone, dispatch a same-day truck, and have hot water back before the basement floods.
Common questions we get on the phone before scheduling a replacement.
A standard 40 or 50 gallon gas tank replacement in Hempstead typically runs $1,800 to $2,800 installed, including the unit, expansion tank, permit, and old-unit removal. Electric tanks run a bit less. Tankless installations run $4,200 to $6,500 depending on venting and gas-line work. Hybrid heat-pump units are in the middle. Every quote is flat-rate and locked in before we start.
A straight tank-for-tank swap is usually 3 to 4 hours including drain, removal, and the new install. Tankless conversions take a full day because of the venting and gas-line work. You will have hot water back the same day for both. Larger jobs (jurisdiction inspections, complex venting, or panel upgrades for hybrid units) sometimes stretch to two days.
If you are happy with the hot-water capacity you have now and want the cheapest install, a tank is the right answer. If you have ever run out during back-to-back showers, want to reclaim the closet space, or you are replacing for the second or third time, tankless is usually worth it. The unit lasts roughly twice as long and uses less energy, so the higher install pays back over years.
Yes. Water heater replacements in Nassau County require a plumbing permit, and we pull it on your behalf as part of the install. We schedule the inspection, meet the inspector on site, and walk through the work. You get a copy of the closed permit for your records, which protects you when you eventually sell the home.
For tank units the rule of thumb is 30 gallons for one bath, 40 for one and a half, 50 for two and a half, and 75 for three or more. If you have ever run out during back-to-back showers, size up one tier. For tankless, sizing is by gallons per minute (GPM) of simultaneous hot-water demand. We do the math on the call so you do not buy more or less than you need.
Included. We drain the old tank, disconnect the water and fuel/electric, walk it out of the closet, and take it with the truck for proper disposal. You do not have a 150 pound steel tank sitting on the curb waiting for sanitation pickup, and you do not pay extra for haul-away.
