Venting and Draft Repair in Charleston, SC
Atmospheric gas water heaters depend on a properly sloped metal flue to carry exhaust out of the home. Disconnected sections, rusted draft hoods and poor slope can let combustion gases spill back. We repair or replace vent sections and verify draft with a test. Proper venting is critical for your family's safety.
Burner Cleaning and Repair in Charleston, SC
A yellow, lazy or noisy flame points to a dirty burner or poor combustion air. We remove and clean the burner, check the orifice size for natural gas or propane and adjust as needed. A clean blue flame heats faster and produces less carbon monoxide. We also check for rust flakes falling from the flue.
Water Heater Tank Leaks and Pressure Issues in Charleston, SC
While gas water heaters are robust, tank leaks or pressure problems can occur. We can often fix small fitting leaks or replace relief valves if pressure is too high. If the tank itself is compromised due to rust or old age, a replacement might be the more sensible long-term solution. We will provide an honest assessment of the repair options for your Charleston, SC home.

Frequently Asked Questions About Gas Water Heater Repair in Charleston
Most gas water heater repairs cost $150 to $700. Thermocouple and pilot work is at the low end, while gas control valves and power vent components are at the high end. We quote before starting.
Yes, if venting is blocked, disconnected or drafting poorly. We check draft on every repair, and we suggest carbon monoxide alarms in every home with gas appliances.
Yes. Labor is warrantied and parts carry manufacturer coverage. We list the terms on your invoice.
Regular maintenance, such as annual flushing of the tank to remove sediment, inspecting the anode rod and checking the pressure relief valve, can significantly extend the life of your gas water heater and prevent common issues. Consider a maintenance plan with KBN Plumbing.
Most common gas water heater repairs, such as replacing a thermocouple or thermostat, can be completed within 1 to 3 hours. More complex issues or those requiring special parts might take longer, but we always aim for same-day resolution whenever possible.
Replacing a part like a thermocouple or gas valve usually does not. Replacing the water heater or altering gas piping or venting often requires a permit, which we handle.
If you smell gas, immediately evacuate your home right away, do not turn any lights or appliances on or off, and call your gas company's emergency line and then KBN Plumbing from a safe location. This points to a potentially dangerous gas leak that requires immediate professional attention.
Yes. Sediment buildup, which is common where water is hard, can insulate the bottom of the tank and make it harder for the burner to heat the water efficiently. This leads to reduced hot water and higher energy bills, and it can even cause premature failure of the unit.
