What Our Customers Say
quality
“Did a great job installing our new water heater. They were really knowledgeable and so professional and kind.”
professionalism
“Replaced our water heater’s expansion tank and installed a pressure relief valve. Patient, thorough, and professional.”
speed
“Very knowledgeable and came out the next day to work on our tankless water heater.”
Resetting the button often won’t bring back hot water if a part has failed. Likely causes include a tripped high‑limit switch, a bad heating element, a failed thermostat, gas control issues, or heavy sediment. Our licensed plumbers service tank and tankless units, using a $179 diagnostic (waived with repair) to pinpoint the problem. We offer same-day and 24/7 emergency water heater service across Nassau County.
- Check the breaker.
- For gas, confirm the valve is on and the pilot is lit.
- Look for leaks around the tank.

Quick steps:

It is usually worth repairing a hot water heater when the problem is a single, fixable part and the tank is structurally sound, but replacement makes more sense when the tank leaks or breakdowns keep returning. The most common fork in the road is a failed pilot light/heating element (repair) versus a leaking tank (replace). Our replacements typically range: tank $3,800–$6,500+ and tankless $7,500–$11,000+, confirmed after a $179 diagnostic that’s waived with any approved repair or replacement. In Long Island homes we service, a pinhole seam or rust-through on the tank is the practical stop sign for repairs.
Look for these decision signals:
- Repair: solid tank, first-time issue, fix involves pilot, thermostat, or heating element.
- Replace: active tank leak/corrosion, frequent failures, or repair cost nearing install pricing.
- Urgent: no hot water plus water pooling near the heater.
If you see water around the heater, shut the cold-water valve and power/gas, then schedule a diagnostic.

Water heater repair pricing is set after our $179 diagnostic visit, and that fee is waived when you approve the repair. We use flat-rate, upfront pricing, so the quoted price is the price. Costs vary by issue and parts, from pilot lights and heating elements to leaks or tankless descaling. If your system is not repairable, replacements typically run $3,800–$6,500+ for tank or $7,500–$11,000+ for tankless. We offer 24/7 emergency service and a Fix or Free pledge.
