Comprehensive Water Heater Services in Salem, NH
From first installation to emergency repair, we cover every phase of water heater ownership. Our technicians help you select the right system for your household or business: the right type, tank size, and fuel source, so you’re not paying for more capacity than you need or living with less hot water than you use.
Installation & Replacement
We install traditional tank water heaters (gas and electric, 30 to 50 gallons), tankless water heaters, and heat pump water heaters. Tankless units heat water on demand rather than storing it, which eliminates standby heat loss from a tank. Heat pump water heaters transfer heat from surrounding air into the water rather than generating heat directly, which can reduce operating costs compared to standard electric resistance water heaters. If your current system is past its useful life, we also handle tank-to-tankless conversions, including any gas line or electrical upgrades the new system requires.
Repair Services
Our technicians diagnose and repair leaks, insufficient hot water, strange noises, pilot light problems, and discolored or foul-smelling water. Water heaters showing signs of age, including units 10 years or older, rusty output, inconsistent temperatures, or pooling around the tank base, are common candidates for evaluation. We’ll tell you honestly whether repair or replacement makes more sense given the age and condition of your unit.
Maintenance & Flushing
Regular maintenance extends the life of your water heater and keeps it running efficiently. Our maintenance service includes tank flushing, component inspection, leak checks, and safety feature testing. Sediment buildup is one of the most common causes of reduced output and premature failure in tank units. A straightforward flush addresses it before it shortens the system’s lifespan.
Emergency Water Heater Repair
A failed water heater doesn’t wait for business hours. Our 24/7 emergency response covers Salem and surrounding communities. Call any time, and our on-call team can dispatch a technician. Because we handle both the plumbing and the gas or electrical work, you won’t need a second contractor to finish the job. Trust Cornerstone Services for complete water heater services in Salem, NH.
