What This Service Includes
Our water heater repair service covers complete diagnostics and repair of traditional tank and tankless water heating systems. Whether you have a gas water heater or an electric model, our licensed plumbers arrive with fully stocked trucks to handle common repairs on the spot. We test thermostats, heating elements, thermocouples, gas valves, and pressure relief valves to pinpoint exactly why your unit is failing.
In addition to component replacement, we perform system flushes to remove hard water sediment, fix leaking supply lines, repair venting issues, and provide complete unit replacements when a tank is structurally compromised or beyond economical repair.
Signs You Need Water Heater Repair
- •No Hot Water: Complete loss of hot water or water that only gets lukewarm.
- •Leaking Tank: Water pooling around the base of the heater or dripping from valves.
- •Rumbling Noises: Loud popping, cracking, or rumbling sounds coming from the tank.
- •Rusty Water: Hot water that appears discolored, brown, or has a metallic taste/smell.
- •Pilot Light Issues: A gas water heater pilot light that won't stay lit.
- •Low Pressure: Hot water pressure that is noticeably lower than the cold water pressure.
Common Causes in Houston Homes
Hard Water Sediment: Houston has notoriously hard water, packed with calcium and magnesium. When water is heated, these minerals separate and settle at the bottom of the tank. Over time, this sediment layer thickens, forcing the burner or heating element to work harder to heat the water through the sludge, leading to overheating, rumbling noises, and premature tank failure.
Failed Thermocouples: In gas water heaters, the thermocouple is a safety device that detects if the pilot light is on. If it becomes coated in dust or fails entirely, it will shut off the gas valve, leaving you with no hot water.
Burnt Out Heating Elements: Electric water heaters typically have two heating elements. If sediment buries the lower element, it can short out. If one element fails, you'll run out of hot water much faster than normal; if both fail, the water will run entirely cold.
What Happens If You Ignore It
Ignoring water heater problems almost always leads to more expensive damage. A small leak from a pressure relief valve or a rusty fitting can suddenly burst, releasing 40 to 50 gallons of water into your home. This causes extensive water damage to drywall, flooring, and structural framing.
Ignoring rumbling noises allows sediment to harden, eventually causing the steel tank to overheat, crack, and rupture. Once the actual tank begins leaking, it cannot be repaired—it must be completely replaced. Addressing issues early saves you from the cost of a full replacement and catastrophic water damage.
How We Fix the Problem
We start by inspecting the unit to determine its age, overall condition, and the source of the failure. For gas units, we check gas flow, pilot assembly, and venting. For electric units, we test the voltage to the thermostats and heating elements.
If it's a component failure (like a bad gas valve, broken dip tube, or burnt element), we drain the unit, replace the faulty part, and restore function. If the tank itself is leaking from the inside out, we will present you with options for a code-safe replacement. We focus on transparent communication—explaining the repair vs. replacement cost so you can make the best decision for your home.
Emergency Situations
A heavily leaking water heater is an emergency. If water is actively flooding your floor, shut off the cold water supply valve located above the heater and call us immediately.
Gas Smell Safety Warning: If you smell gas (a rotten egg odor) near your water heater, leave the property immediately and contact the gas utility or emergency services first. Do not use switches, flames, or phones inside the property. After the immediate safety concern is handled by the utility company, call our qualified plumbing professionals to repair the gas leak or replace the faulty appliance.

Frequently Asked Questions
Why do I have no hot water?
No hot water can be caused by a failed heating element in an electric heater, a extinguished pilot light or faulty thermocouple in a gas heater, a broken thermostat, or severe sediment buildup in the tank. We can diagnose the exact cause and perform targeted repairs.
Is a leaking water heater an emergency?
Yes, a leaking water heater is a plumbing emergency. Even a small drip can quickly turn into a major tank rupture, flooding your garage, attic, or home interior. Shut off the water supply to the heater immediately and call for emergency service.
Why is my water heater making a rumbling noise?
Rumbling, popping, or knocking noises indicate a heavy layer of sediment has built up at the bottom of the tank. In Houston, our hard water causes rapid mineral scaling. The noise happens when water trapped under the sediment boils and forces its way up. This reduces efficiency and can cause tank failure.
How long does a water heater last in Houston?
Due to Houston's hard water conditions, traditional tank water heaters typically last 8 to 12 years, while tankless units can last 15 to 20 years with proper maintenance. Regular flushing extends the lifespan significantly.
Should I repair or replace my water heater?
If your water heater is over 10 years old, has a leaking tank, or requires repairs that cost more than 50% of a new unit, replacement is usually the better investment. We offer honest assessments and will never push a replacement if a simple repair will safely extend the unit's life.

Water Heater Questions Houston Homeowners Ask
How much does water heater repair cost in Houston?
Water heater repairs in Houston typically range from $150-$500 depending on the problem. Simple fixes like thermostat replacement cost $150-$300, while heating element replacement runs $200-$400. Complete water heater replacement costs $1,200-$2,500 installed.
Should I repair or replace my water heater?
Replace your water heater if it's over 10 years old, leaking from the tank (not connections), requires multiple repairs, or repair costs exceed 50% of replacement cost. Repair if it's under 8 years old, the problem is a single component (thermostat, element, valve), and the tank isn't leaking.
How long do water heaters last in Houston?
Water heaters in Houston typically last 8-10 years, shorter than the national average of 12-15 years. Houston's hard water (120-180 ppm minerals) accelerates sediment buildup and internal corrosion. Regular maintenance (annual flushing, anode rod replacement every 3-5 years) can extend lifespan to 12+ years.
