Water Heater Repair & Replacement in Garland and Mesquite
Your water heater is one of the hardest-working appliances in your home, running every day without much notice — until it stops. At The Service Genie, we've diagnosed and repaired every type of water heater issue that DFW homeowners encounter: no hot water, not enough hot water, rusty water, water pooling at the base of the unit, and pilot light failures.
We're licensed by the Texas State Board of Plumbing Examiners, which means every water heater installation we complete meets Texas code requirements. Whether you need a repair on your existing unit or a full replacement, we'll walk you through the options and let you make an informed decision.
How Long Does a Water Heater Last?
Traditional tank water heaters typically last 8 to 12 years. Tankless units can last 15 to 20 years with proper maintenance. The hard water found in much of the DFW area — with its high mineral content — can accelerate sediment buildup and reduce the effective lifespan of any water heater. Regular flushing extends the life of your unit and maintains heating efficiency.

Signs Your Water Heater Needs Attention
- No hot water or water that runs cold much faster than it used to
- Rusty, brown, or discolored hot water coming from faucets
- Rumbling, popping, or banging sounds from the tank — a sign of sediment buildup
- Water pooling around the base of the unit
- The unit is more than 10 years old and showing any of the above symptoms
- Pilot light that won't stay lit (gas units)
- Lukewarm water even when the thermostat is set correctly
- Noticeably higher gas or electric bills without a change in usage
If water is actively leaking from the base of your water heater, shut off the cold water supply to the unit immediately and call us. A leaking tank typically cannot be repaired — it needs to be replaced before it causes water damage to your floors and walls.
Common Water Heater Problems We Repair
- Faulty or failed thermostat
- Broken heating element (electric units)
- Pilot light and ignition issues (gas units)
- Sediment buildup causing reduced efficiency and noise
- Corroded anode rod — the sacrificial rod that protects your tank from rust
- Pressure relief valve failure
- Loose or corroded connections
- Undersized unit that can't keep up with household demand
Tank vs. Tankless: Which Is Right for Your Home?
Traditional Tank Water Heaters
Tank units store and continuously heat a set volume of water — typically 40 to 50 gallons for a family home. They are less expensive to purchase and install, and simpler to repair. For most Garland and Mesquite homeowners on a budget or with straightforward hot water needs, a quality tank unit is the right choice.
Tankless Water Heaters
Tankless units heat water on demand, eliminating standby heat loss and providing an endless supply of hot water. They are more expensive upfront but can reduce energy costs and last significantly longer. They're a strong option for larger households or homeowners planning to stay in their home long-term. We install and service all major tankless brands.

Frequently Asked Questions
Should I repair or replace my water heater?
If your unit is under 8 years old and the repair cost is less than half the price of a new unit, repair is usually the better investment. If the unit is older, if the tank itself is leaking, or if repairs are becoming frequent, replacement makes more sense. We'll give you an honest recommendation after inspection.
How long does water heater installation take?
Most standard tank replacements can be completed in two to three hours. Tankless installations take longer — typically half a day — especially if gas line modifications or new venting is required.
Do I need a permit to replace a water heater in Texas?
In most jurisdictions in the DFW area, yes — a permit is required for water heater replacement. As a licensed plumber, The Service Genie handles permit requirements as part of the installation process.
Why does my hot water smell like rotten eggs?
A sulfur or rotten egg odor typically comes from a deteriorating anode rod reacting with bacteria in the water. This is more common with well water or water that sits in the tank for extended periods. We can replace the anode rod or recommend treatment options.
How often should I flush my water heater?
Annually, at minimum — and more frequently if you have hard water. Regular flushing prevents sediment accumulation that reduces efficiency and can eventually damage the tank. We can handle this as part of a routine maintenance visit.
