What the job involves
Water heater repair starts with finding the cause—like a faulty thermostat, a leaking pressure valve, or a tank that's rusting through. We'll either fix the part or recommend replacing the unit if it's too far gone. For installs, we handle everything from disconnecting the old unit to hauling it away, setting up the new one, and adjusting the temperature. Most Charleston homes have standard 40 or 50-gallon tanks, but we also work with tankless systems if that's what you need. The job includes checking the water pressure and making sure the gas or electric connections are right.
Charleston-specific challenges
Older homes here often have water heaters in tight spaces—cramped closets or under houses with low clearance. That can make swaps tricky, but we're used to it. Salt air also causes faster corrosion, so we check the anode rod and tank condition closely. If your home is on a pier foundation, we make sure the lines are supported right during installs. And with our humid climate, we watch for condensation issues that can lead to leaks or mold around the unit.
When to call & what we check first
Call us if your water heater leaks, makes popping or rumbling sounds, or can't keep up with hot water demand. Rusty water or a metallic smell means it's time for a look. When we arrive, we first check the age of the unit—most last 8-12 years here. We test the pressure relief valve, look for leaks at the base, and listen for sediment buildup. If it's an install, we measure the space and check your home's gas or electric capacity to match the right model.
Questions about water heater repair & install
How do I know if my water heater needs repair or replacement?
If your water heater is under 8 years old and acting up, we can often repair it—like replacing a heating element or fixing a leaky valve. But if it's older, leaking from the tank itself, or constantly needing fixes, replacement usually makes more sense. We'll tell you what we find and let you decide. Charleston's hard water means tanks wear out faster here, so we check for rust or scale buildup that shortens their life.
Should I switch to a tankless water heater?
Tankless systems save space and energy, but they work best if your home's gas line or electrical panel can handle them (older Charleston houses often need upgrades). They're great if you use hot water steadily, but can struggle if multiple showers run at once. We'll check your home's setup and usage to see if it's a good fit. Tankless units cost more upfront but last longer—especially useful here with our corrosive coastal air.
What should I do while waiting for a repair?
If you have a leak, find the shut-off valve on the water heater or turn off your home's main water supply. For electric heaters, flip the breaker to avoid damage if the tank is empty. Don't try to relight a gas heater's pilot light yourself—wait for us. You can drain a few gallons from the tank to clear sediment, but avoid full drains unless it's leaking badly. Call us if the problem gets worse before we arrive.
