Real answers from the techs who do the work. If your question is not here, just call.
Yes. Most calls placed before noon get a new unit installed the same day. The trucks roll out of the shop with the common tank sizes (40, 50, and 75 gallon) already loaded, so we are not waiting on a supplier when you have no hot water.
Tankless replacements and unusual sizes can sometimes take a day or two if we need to grab a specific unit, but the standard 50-gallon swap is almost always same day.
Phones are answered 24 hours a day, 7 days a week, by a real person. Installs run 7 days a week, including evenings for emergencies. Standard daytime install hours are roughly 8am to 6pm.
All of Nassau and Suffolk Counties. From Manhasset to Montauk and everywhere in between. We do not currently serve Queens, Brooklyn, or the boroughs.
For a full list of towns we cover every week, see our Service Areas page.
Honestly, it depends on where you are and what time of day you call. Average response window for an emergency in central LI is 2 to 4 hours from the call. We will give you a real ETA on the phone, not a vague promise.
No. We focus on residential water heater replacement and repair only. That focus is what lets us be fast and stock the trucks correctly.
Rough ranges for a standard residential install, all-in (unit, labor, code-compliant install, permit, haul-away of the old unit):
See our cost page for the full breakdown.
Phone estimates are free and we are pretty accurate over the phone after a few quick questions. On-site quotes are also free if the situation needs eyes (unusual install location, code corrections suspected, custom venting).
Yes. We offer financing through our partners including 0% APR options for qualified buyers. Application takes a few minutes. See the financing page for current offers.
Often yes. PSEG Long Island offers rebates on heat pump water heaters. National Grid offers rebates on high-efficiency gas units. There is also a federal tax credit on heat pump units (30%, up to $2,000).
We file the utility paperwork on your behalf at no extra charge. Details on the rebates page.
No. Permit, haul-away, and standard fittings are included in the quoted price. The only things that add cost are code corrections (if your existing setup is not to current code) or unusual install conditions (rerouting gas, electrical, or venting). We discuss those with you before doing the work, not after.
A real Domino company member picks up, asks a few quick questions about your existing unit and the issue, and gives you a price range and an ETA. If you say yes, we schedule and a tech is on the way. No call centers, no transfers, no upsell scripts.
A standard tank-for-tank replacement runs about 2 to 3 hours start to finish. Tankless retrofits or installs that need code corrections can run 4 to 6 hours.
Yes, included in the quote. The old tank is recycled. You do not have to deal with it.
Yes. We pull permits in Nassau and Suffolk and meet local plumbing code on every install. Some homeowners ask why we bother. Two reasons: it is the law, and it protects you on your homeowners insurance and at resale.
An adult does need to be on site, but you do not need to babysit us. The tech will check in when arriving, ask where the unit is, and let you know when the work is wrapping up.
Quick test: how old is it? If it is over 10 years old or leaking from the tank itself, replace. If it is under 8 years and the failure is a small part (thermocouple, element, valve), repair is usually the smarter spend.
Full decision guide here: Repair vs Replace Your Water Heater.
Tank units last 10 to 12 years on average, sometimes longer with maintenance. Tankless units last 15 to 20 years. Long Island's hard water tends to shorten those numbers by 1 to 3 years unless the unit is flushed annually.
Not usually. A pilot light that will not stay lit is most often a failing thermocouple, which is a cheap part. If the unit is otherwise healthy and under 10 years old, repair almost always wins.
Rule of thumb for tank units:
See our sizing guide for a closer look.
Maybe. Tankless wins for big families, long-term homeowners, and people who hate running out of hot water. It loses on upfront install cost, and it needs more maintenance in hard-water territory.
Full breakdown: Tank vs Tankless.
If your home has gas, gas is usually the answer for performance and operating cost. Electric is fine for smaller demand or where gas is not available. Hybrid heat pump units are the most efficient option (and the only ones that earn the big PSEG-LI rebate), but they need a basement or garage with enough air volume around them.
Yes. Fully licensed in Nassau and Suffolk Counties, fully insured, and our techs are background checked. We pull permits on every install.
Since 1981. Family-owned the whole time. We are not a national chain pretending to be local.
Every install gets a written labor warranty plus the full manufacturer warranty on the unit itself. If anything is wrong with the installation, we come back and fix it. Details on the warranty page.
Employees. Every tech who pulls up in a Domino van went through our training and is on our payroll. We do not subcontract installs to third parties.
