A damaged or outdated gas line can lead to serious safety issues, including leaks, fire hazards, and carbon monoxide poisoning. When a gas line is beyond repair or unable to meet your home’s needs, a full replacement is necessary.
Gas line replacement ensures that your home remains safe, your appliances function properly, and your gas system meets the latest safety standards. A new gas line will improve the efficiency of your system, potentially lower energy bills, and provide you with reliable, safe service for many years to come.
Tennessee Standard Plumbing’s experienced team works quickly and carefully to replace your gas line, minimizing disruption and ensuring top-quality results.

Sometimes, repairing an old gas line isn’t enough to restore its safety and efficiency. Here are some signs it’s time for a gas line replacement:

If your gas line shows signs of rust, cracks, or leaks, it’s time to replace it.

Repeated gas leaks can indicate that your line is deteriorating and needs replacing.

Older homes may have outdated gas lines that no longer meet safety codes or can handle modern gas appliances.

If you notice an unexplained spike in your gas bill, your old gas line may be leaking or inefficient.

If your appliances (water heater, stove, dryer) are not performing well, it could be due to a failing gas line.
If you notice any of these issues, contact us for a professional evaluation and replacement estimate.


If something goes wrong with our workmanship, we make it right—no excuses, no runaround, even if it means covering the cost ourselves.

You’ll always receive multiple options and a clear price before any work begins. Once you approve, that price won’t change.

We respect your schedule. If we miss our arrival window, we waive the service fee.

If your gas line is old, shows signs of damage, or has frequent leaks, it may be time for a replacement. Increased utility bills or poor appliance performance can also signal that your gas line is no longer functioning properly.
Gas line replacement typically takes a day or two, depending on the complexity of the job. Our team works efficiently to minimize disruption and complete the job safely and professionally.
Homeowner’s insurance may cover gas line replacement if the damage is due to an accident or covered event, but it’s important to review your policy to determine if repairs or replacements for wear and tear are covered.
Modern gas lines are typically made of durable materials like copper, flexible stainless steel, or polyethylene, which provide long-lasting performance and comply with safety standards.
Yes. Older black iron or steel lines can often be replaced with modern, code-approved materials that are better suited for today’s gas demands. We’ll inspect your current system and recommend the right pipe type and size for your appliances and layout.
We can replace gas lines that run indoors (to ranges, fireplaces, dryers, water heaters, etc.) as well as buried or exterior lines that serve grills, outdoor kitchens, fire pits, or standby generators, as long as conditions and access allow.
In some cases, yes. We may need to open small sections of walls, ceilings, or exterior surfaces—or dig limited trenches—to access and replace the lines safely. We plan routes to be as minimally invasive as possible and clean up our work areas when the job is done.
Many gas line replacements require permits and inspections. We follow Tennessee and local Knoxville code requirements and will let you know what’s needed for your specific project. We’ll help coordinate the permitting and inspection process as part of the job.
In many situations, yes. We’ll let you know which areas will be affected and when, and we follow strict safety and testing procedures before turning the gas back on. If we ever believe it’s safer for you to be out of the home during a particular phase, we’ll explain that clearly in advance.
Yes. Our plumbers are properly licensed, follow Tennessee and local Knoxville code requirements, and our work is fully insured to help protect your home or business.
