Dependable service, everyday comfort
Water heaters work hard every day, and when they fail, your whole home or business feels it. We service tank and tankless systems, diagnose problems accurately, and complete safe, code-compliant repairs or replacements to get hot water flowing again.
Problems we solve
From no hot water and leaking tanks to aging systems and tankless error codes, we accurately identify the problem and recommend the right solution for your home.
No hot water
When your water suddenly turns cold, it may be due to heating element failure, gas supply issues, ignition problems, or internal component wear.
Leaking water heater
Water around your unit can signal loose fittings, valve failure, or in some cases, tank deterioration that requires prompt attention.
Pilot light issues
If your pilot light won’t stay lit, the cause may be a faulty thermocouple, gas control issue, or ventilation concern.
Tankless error codes
Tankless systems display error codes when they detect combustion, flow, or sensor issues. We diagnose the code and correct the root cause.
Not enough hot water
Running out of hot water quickly may indicate sediment buildup, undersizing, or burner or element problems.
High energy bills
An aging or inefficient water heater can use more gas or electricity than necessary, increasing monthly utility costs.
Old or unsafe systems
Outdated systems that are improperly vented or missing safety components can pose performance and safety concerns.
Upgrades and remodels
We help homeowners upgrade to more efficient systems or relocate water heaters during remodel projects.

Frequently asked questions
Repair costs depend on the type of water heater and what needs to be fixed. We provide a flat-rate diagnosis and quote before any work begins, so you know exactly what to expect.
Standard tank water heater replacements typically range from $2,300 to $5,500, while tankless installations can range from $4,500 to $8,500 depending on the system, location, and any required code upgrades.
Tank water heaters typically last 8 to 12 years, while tankless systems can last 15 to 20 years with proper maintenance. Age, water quality, and usage all affect lifespan.
It depends on the age of the unit, the cost of the repair, and its overall condition. If the system is over 10 years old and requires a major repair, replacement is often the better long-term value.
This can be caused by a failed heating element, a tripped breaker, a pilot light that went out, or a gas supply issue. We can diagnose the cause quickly and explain your options.
A leak can indicate a failing pressure relief valve, loose fittings, or internal tank corrosion. Even small leaks should be inspected promptly to prevent water damage.
Most standard tank replacements are completed in 2 to 3 hours. Tankless installations typically take 4 to 6 hours, depending on whether gas line or venting modifications are needed.
