Comprehensive Water Heater Repairs

From quick fixes to full maintenance programs, our certified plumbers handle every repair your tank water heater needs — backed by our flat diagnostic fee ($89 residential / $150 commercial) and 12-month workmanship guarantee.

Heating Element Replacement

Most Common Repair

Electric water heaters rely on upper and lower heating elements. When one fails, you get lukewarm or cold water. We diagnose which element is faulty and replace it the same visit.

Signs you need this:

  • Only lukewarm water
  • No hot water at all
  • Top half cold, bottom warm

Anode Rod Replacement

Lifespan Extender

The sacrificial anode rod protects your tank from corrosion. Replacing it every 3–5 years is the single most impactful thing you can do to double or triple your tank's lifespan.

Signs you need this:

  • Rotten egg smell
  • Rusty water
  • Tank older than 4 years

Annual Tank Flush & Descale

Annual Service

Sediment from hard water accumulates at the bottom of your tank, reducing efficiency, increasing energy costs, and shortening tank life. Our annual flush removes buildup completely.

Signs you need this:

  • Popping or rumbling sounds
  • Higher energy bills
  • Slower recovery time

Thermostat Repair & Calibration

Precision Calibration

Faulty thermostats cause water that's too hot, too cold, or inconsistent. We test, repair, or replace both upper and lower thermostats and calibrate to your preferred temperature.

Signs you need this:

  • Water too hot/cold
  • Inconsistent temperatures
  • Thermostat not clicking

Pressure Relief Valve Service

Safety Critical

The T&P (temperature & pressure) relief valve is a critical safety component. We inspect, test, and replace faulty valves to prevent dangerous over-pressure conditions.

Signs you need this:

  • Valve dripping constantly
  • Valve hasn't been tested in 3+ years
  • Rumbling or hissing from valve

Dip Tube Replacement

Quick Fix

The dip tube directs cold inlet water to the bottom of the tank for heating. A cracked or broken dip tube mixes cold water at the top, giving you consistently lukewarm showers.

Signs you need this:

  • Always lukewarm showers
  • Plastic bits in water
  • Short hot water supply

Expansion Tank Installation

Code Compliance

Closed plumbing systems require a thermal expansion tank to prevent pressure buildup from heated water. We install and size expansion tanks to code for your home's system.

Signs you need this:

  • Pressure relief valve dripping
  • Closed plumbing system
  • Water pressure fluctuations

Igniter & Burner Repair

Gas Specialist

Gas water heater ignition failures leave you without hot water. We repair faulty pilot lights, thermocouples, igniters, and burner assemblies on all major gas water heater brands.

Signs you need this:

  • Pilot won't stay lit
  • No ignition click
  • Burner flame is yellow/orange

Maximize Your Investment

Extend Your Water Heater's Life by Years

A properly maintained tank water heater can last 12–15 years instead of the average 8–10. Here's how proactive maintenance pays off.

Annual Tank Flush

Every Year

Flushing sediment once a year prevents efficiency loss and reduces corrosion on the tank lining.

Impact: +3–5 years

Anode Rod Check

Every 3–5 Years

Inspect and replace the sacrificial anode rod every 3–5 years to protect the tank from internal rust.

Impact: +5–8 years

T&P Valve Test

Every Year

Manually test the temperature & pressure relief valve annually to ensure it operates safely and hasn't seized.

Impact: Safety-critical

Thermostat Calibration

Check Annually

Keep temperature set to 120°F — hot enough to kill bacteria, low enough to prevent mineral buildup and scalding.

Impact: 15–20% energy savings

Insulation Blanket

One-Time Install

An insulation wrap on older tanks reduces standby heat loss by up to 45%, lowering your monthly energy bill.

Impact: Up to 45% standby savings

Expansion Tank Service

Every Year

Check your expansion tank's pre-charge pressure annually to protect your tank from thermal expansion stress.

Impact: Prevents pressure damage

When Repair Makes Sense

  • Tank is under 8 years old
  • Issue is limited to one component
  • No rust on the tank body or in water
  • Repair cost is less than 40% of replacement
  • Unit was well-maintained previously

When It's Time to Replace

  • Tank age 10+ years (electric) or 8+ years (gas)
  • Visible rust or corrosion on the tank body
  • Persistent rust-colored water despite flushing
  • Leak at the base of the tank (not fittings)
  • Repair costs exceed 50% of replacement cost
  • Multiple component failures within 12 months
