Frequently Asked Questions

How often should home gas lines be inspected?

There is no universal schedule, but a sensible rhythm is a visual check of accessible piping every few years, plus a professional inspection with pressure testing when buying an older home, after major flooding or a hurricane, or whenever warning signs appear. Homes with aging steel systems in older neighborhoods benefit from closer attention than newer homes with modern materials.

Do underground gas lines last longer than indoor ones?

Often, yes — but material is the deciding factor. Modern polyethylene lines buried underground are protected from the physical knocks and temperature swings of interior spaces and do not corrode, so they tend to age gracefully. Older buried steel can actually fare worse than indoor steel, because soil moisture and chemistry attack it from the outside. It is the material-and-conditions combination that determines the outcome, not the location alone.

Which gas line material holds up best?

For buried exterior use, polyethylene is the modern answer — it simply does not corrode in soil. Indoors, both black steel and CSST are proven performers when properly installed. The honest answer is that the ‘best’ material is the right material for the location, installed correctly for the soil and conditions it will face — which is why material selection should follow an assessment of your specific situation.

Can an old gas line be relined instead of replaced?

Gas lines are generally not relined the way some water or sewer pipes are. The standard practice is to cut out the damaged section and replace it, or to replace the full run when the system’s condition warrants it. Relining technologies that work for drain pipes do not transfer to pressurized fuel-gas piping, so replacement — partial or full — is the accepted path.

Does Texas clay soil really affect how long gas lines last?

Yes, it can. The expansive clay soils common across the Dallas-Fort Worth metro — including Denton County — retain moisture against buried pipe and move through seasonal shrink-and-swell cycles that stress rigid joints. Over time that combination of chemical and mechanical attack shortens the service life of vulnerable installations, which is why proper bedding, depth, and material choice matter so much here.

Who is responsible for the gas line on my property?

Generally, the utility owns and maintains the line up to and including the meter — that is their equipment and their responsibility. Everything past the meter — the piping running into and through your home — belongs to the homeowner, including its maintenance, repair, and replacement. If you are ever unsure where the boundary sits on your property, your gas utility can clarify.
