Gas Leak Safety — Read This First
If you suspect a gas leak, do not operate any switches, do not open windows, and do not try to locate the source yourself. Evacuate your home immediately and call your gas provider from outside. Once the utility company has cleared the property, call us — we’ll inspect your HVAC equipment before it’s returned to service.
Licensed Gas Line Work for Knoxville & Knox County Homes
Natural gas and propane power some of the most important appliances in your home — your furnace, water heater, range, dryer, and fireplace among them. When those lines are properly installed and maintained, they’re safe and reliable for decades. When they’re not, the consequences can be serious. Our licensed technicians handle every aspect of residential gas line work, from new installations and extensions to leak detection, repair, and full system inspections.
All gas work we perform is done to code, permitted where required, pressure tested before any appliance is connected, and inspected by the appropriate authority. There are no shortcuts on gas.
Whether you’re adding a gas appliance for the first time or building a new home, new gas line installation starts with a plan. We design the piping system to deliver adequate pressure and volume to every appliance it serves, accounting for the total BTU demand of all connected equipment and the distance from the meter.
We install gas lines for the following applications:
In all cases, we pull the required permits, coordinate with KUB for meter upgrades if needed, and schedule inspections with the city or county.
Sometimes an existing gas line is close to where you need it but not quite there — or a renovation, addition, or appliance relocation requires moving or extending the current piping. This is some of the most common gas work we do.
Typical extension and rerouting projects include:
Before any extension work, we assess the existing system — meter capacity, main line sizing, and current total BTU load — to confirm the existing infrastructure can support the addition. If the existing meter or service line is undersized, we coordinate with the gas utility to have it upgraded before proceeding.
Black Iron Pipe — Our #1 preferred method. The traditional standard for residential and commercial gas lines. Threaded black iron is durable, widely available, and accepted by all codes for interior and exterior applications. It is the preferred material for high-BTU applications like generators and commercial cooking equipment.
CSST — Corrugated Stainless Steel Tubing — A flexible, modern alternative to rigid black iron that routes through walls, floors, and tight spaces without the number of fittings that rigid pipe requires. CSST significantly reduces installation time and the number of potential leak points. It must be properly bonded and grounded per current code requirements, which we always include in our installations.
Flexible Appliance Connectors — The final short connection between the gas shutoff valve and the appliance itself. These are not permanent piping — they are listed for specific appliances, have a limited service life, and must never be concealed inside walls. We inspect these during every service visit and replace them when they show age or corrosion.

A gas leak can be gradual and go unnoticed for an extended period, or it can be a sudden failure that requires immediate action. Either way, detecting and locating the leak accurately is the first step.
Signs you may have a gas leak include the smell of rotten eggs or sulfur anywhere in or around your home, a hissing or whistling sound near a gas line or appliance, dead or discolored vegetation in a line path in your yard, higher-than-expected gas bills with no change in usage, and the gas company detecting an issue at your meter.
What we do during a leak detection service:
Pressure Testing — We isolate sections of your gas system and apply a measured test pressure to identify where pressure is dropping. This tells us definitively whether a leak exists and helps us localize it.
Electronic Gas Detection — We use calibrated combustible gas detectors to trace leaks to their exact location along pipe runs, at fittings, at valve bodies, and at appliance connections. These instruments detect gas concentrations well below what the human nose can smell.
Soap Solution Testing — For visible connections and fittings, we apply an approved leak detection solution to confirm and visually identify leak points. This is done in addition to electronic detection, not instead of it.
Meter and Regulator Inspection — We inspect the gas meter, service regulator, and main shutoff area for signs of corrosion, damage, or leakage. If the meter or regulator itself is the issue, we coordinate with KUB — those components are the utility’s responsibility, but we facilitate the process.
Appliance Connection Inspection — Flexible appliance connectors, shutoff valves, and appliance gas train components are all inspected as part of a thorough leak search.
Once a leak is located, we explain exactly what we found and what the repair involves before beginning any work. Depending on the location and severity, leak repairs may include the following.
Fitting and connection retightening or replacement — Many leaks occur at threaded fittings that have loosened over time or were not made up with proper thread sealant. We remove the fitting, clean the threads, apply the correct sealant for gas service, and reinstall.
Section replacement — Corroded, damaged, or improperly installed sections of pipe or CSST are cut out and replaced entirely. We never attempt to repair corroded pipe in place.
Valve replacement — Shutoff valves that are leaking through the stem or body are replaced with new valves of the appropriate size and pressure rating.
Flexible connector replacement — Aged, kinked, or corroded appliance connectors are replaced with new listed connectors. This is never a repair situation — a damaged flexible connector is always replaced.
Full system replacement — In cases where the existing gas piping is significantly corroded, incorrectly sized, non-code-compliant, or too old to repair reliably, we provide an assessment and proposal for full repiping.
After every repair, the system is pressure tested to confirm the leak has been fully resolved before gas is restored and appliances are reconnected.
If you’ve purchased an older home, if it’s been years since anyone looked at your gas system, or if you’ve had repeated service issues with gas appliances, a full gas system inspection is a smart investment. Many homeowners have never had their gas lines looked at since the house was built.
A gas system inspection covers the condition and age of all visible and accessible gas piping throughout the home, correct material usage and compliance with current code requirements, proper bonding and grounding of CSST where present, condition and operation of all shutoff valves, condition of all flexible appliance connectors, verification that all appliances are properly connected and venting correctly, and a pressure test of the system.
We provide a written report of findings following every inspection, including photographs of any areas of concern. If no issues are found, you have documented peace of mind. If issues are found, you have a clear, prioritized list of what needs to be addressed and what it will cost.
