A pilot that won't stay lit, a tank that's started to weep, or a heater that just can't keep up — we diagnose it on the first visit. When replacement makes more sense, we size the new tank or tankless unit to your household instead of installing whatever happens to be on the van.
Water on the floor near the heater isn't always the tank — a leak detection check can find a failed valve or fitting. In homes where the boiler also makes the hot water, we service both together.
Signs you need water heater repair & installation
- No hot water, or hot water that runs out fast
- Water pooling around the base of the tank
- Rumbling or popping sounds
- Rusty or discolored hot water
- A pilot light that keeps going out
How it works
- Diagnose the burner, thermocouple, thermostat, anode and tank condition.
- Repair on the spot when the unit is worth fixing.
- If it isn't, recommend a correctly sized tank or tankless unit at a flat price.
- Install, test and haul away the old heater.
What affects the cost of water heater repair?
Every job gets a flat, written price after diagnosis. These are the main factors that move that price:
- Repair versus replacement — a thermocouple or valve costs far less than a new tank
- Size and type: standard tank, high-efficiency or tankless
- Venting, gas line or electrical changes for a new unit
- Access — a tight closet or narrow basement stairs add labor
How to prevent problems
- Flush sediment from the tank once a year
- Test the temperature-and-pressure relief valve annually
- Check the anode rod every few years and replace it when worn
- Keep the thermostat near 120°F to limit scale and scald risk
NYC hot water rule: Under NYC HPD rules, building owners must supply hot water 365 days a year at a constant minimum of 120°F.

Frequently asked questions
How long does a water heater last?
A typical tank water heater lasts about 8–12 years. A leak from the tank itself usually means it's time to replace it.
Is tankless worth it?
Tankless units give endless hot water and free up space, but cost more up front. We'll lay out the numbers for your home.
Can you install the same day?
Often, yes — we carry common tank sizes and can usually restore hot water the same or next day.
