Plumbing costs depend on your project and location. Check with a local pro for your specific job.
Moving a gas line costs $375 to $750 for your project, depending on distance and complexity.
Interior kitchen and utility room moves cost more because your plumber must work around tight spaces and structure.
Budget for permits at $150 to $200 so your gas line move meets local code.
Hiring a local plumbing professional keeps your household safe from gas leaks, fires, and carbon monoxide exposure during relocation.
In 2026, the national average cost to move a gas line is $500, with most homeowners paying $375 to $750. This breaks down to $15 to $25 per linear foot. Key cost drivers include how far the line needs to be moved, the reason for relocation—such as appliance installation or code compliance—and permit fees ranging from $150 to $200.
Rerouting a gas line costs $15 to $25 per linear foot, covering both materials and labor. Larger projects—such as converting your stove from electric to gas or upgrading an older home—push costs toward the higher end due to the increased scope of work. Smaller jobs, like extending a line for a new appliance, land at the lower end of that range.
Let's take a look at the main factors that affect the cost to move a gas line, including materials, labor, and permits.
| Cost Factor | Average Cost in 2026 |
|---|---|
| Materials | $1–$10 per linear foot |
| Labor | $75–$200 per hour |
| Permits | $50–$200 |
Gas line pipe materials cost $1 to $10 per linear foot, and the right type depends largely on your local code requirements. The table below breaks down the average cost of common gas line pipe materials, as well as a description of each:
| Gas Line Pipe Material | Average Cost (per Linear Foot) | Description |
|---|---|---|
| Black iron | $5–$10 | Standard for indoor gas lines |
| Flexible corrugated stainless steel tubing (CSST) | $2–$5 | Flexible piping, easy to install, popular for indoor installations |
| Galvanized steel | $3–$10 | Not often recommended because the zinc coating can flake off and clog appliances |
| PVC | $1–$3 | Only used for underground outdoor gas lines, often not permitted |
| HDPE | $1–$5 | Only used for underground outdoor gas lines |
Moving a gas line requires hiring a local plumber, and labor typically runs $75 to $100 per hour. Master plumbers with advanced credentials can charge as much as $200 per hour, making their expertise the higher-cost option for complex or high-stakes jobs.
Where your gas line is located directly impacts the total project cost. Kitchens and utility rooms are the most expensive areas to work in because their dense mix of appliances, plumbing, electrical, and structural components requires careful navigation. Interior lines add cost through wall and floor cuts, drywall removal, and structural access work. Exterior lines can involve trench digging, but they're generally less invasive and less costly to move than interior ones.
When estimating gas line moving costs by distance, plan on $15 to $25 per linear foot. The farther a gas line needs to move, the more you'll pay—longer runs require more materials, more labor hours, and potentially additional permits. Complex routes with many turns add further cost on top of the base distance.
Longer gas line runs require more pipe, which drives up both material and labor costs. Pipe diameter also plays a role—larger pipes cost more to purchase and are more labor-intensive to install than smaller ones.
Difficult site conditions—like cramped crawl spaces or lines running behind finished walls—make gas line work more time-consuming and expensive. Outdoor obstructions such as trees, rocks, or concrete slabs add similar challenges, requiring extra effort and driving up the overall project cost.
Permit costs for gas line relocation run $50 to $200, depending on your municipality. Moving a gas line almost always requires a permit, and skipping this step can lead to project delays and fines.
Underground gas line work requires hiring an additional pro to excavate, and excavating land to dig a trench costs $50 to $200 per cubic yard. Once the line is in place, you may also need a local landscaper to restore any yard or patio areas disturbed by digging, at an additional cost of $1,500 to $5,000.
Hiring a local plumber to move a gas line costs $75 to $100 per hour for labor. This is not a DIY project—working with natural gas is dangerous, and licensed pros have the training and certification required to do it safely.
Plumber: $75–$100/hour
Master plumber: $200/hour
When moving a gas line, you should always work with a certified local plumber for these reasons:
Natural gas is highly flammable, and leaks can be difficult to detect without specialized tools and training.
Improper gas line installation poses serious risks to you and your family, including gas leaks, carbon monoxide exposure, fires, and explosions.
Professional plumbers are familiar with local building codes, permitting requirements, and safety regulations.
Gas line relocation may involve challenging conditions; for example, the line could be buried underground or located behind drywall or under floors, requiring specialized equipment.
DIY gas work can void your home insurance, warranties, and local compliance requirements.
Professionals can identify related issues, such as outdated piping, before it becomes a hazard.
Moving a gas line is a complex project that always requires a professional. Even so, there are ways to minimize costs, including the following:
Get quotes from at least three pros to compare prices. Don't automatically choose the lowest bid, which could indicate a lack of experience or subpar materials.
Schedule during a plumber’s off-season (like late winter or early spring) for better rates.
Consider bundling other plumbing work at the same time.
Ensure your contractor is planning the most straightforward route, avoiding unnecessary bends and turns, which may become costly.
You should never move a gas line yourself, but you may be able to tackle some prep work, such as ensuring the installation area is clear.
You also might handle cosmetic repairs yourself after the gas line is moved, such as repairing drywall and painting it.
Discuss which gas line material is safest and most cost-effective for your home.
Request a breakdown of the estimated project costs, including labor, materials, permit fees, and additional charges for accessing hard-to-reach lines.
Confirm the contractor will obtain the necessary permits.
See if your current gas appliances or connections need upgrades.
