Gas Piping Cost Estimator

The installation and/or repair of gas piping is a standard home improvement and maintenance project connected to a variety of common appliances such as gas stoves, clothes dryers and heaters. Though conceptually it’s a pretty simple process, the volatile nature of the gas carried in the pipes and the inherent danger of working with it makes this a job that’s often best left to the pros. As a homeowner, however, understanding the hows and whys of gas pipe installation and repair, including the factors that contribute to the total cost of the project, is still important.

Gas Pipe Costs

Depending on the type of gas piping you need and the current state of the pipe systems in your home, installation and repair costs for a gas line can vary from as little as nothing (when a gas company includes the line setup as part of its service) to several hundred dollars (when running a new line or if repairs are complex, lengthy and/or dangerous). On average, homeowners report spending between $250 and $700 for gas piping services.

Gas Piping Cost Factors

Gas Piping Cost Factors

The cost of your gas piping job is directly related to the complexity and size of that job in terms of both the materials needed and the time it takes to complete the work. Materials mostly include the piping itself as well as fittings, mounts and any associated hardware. In many areas of the country, only licensed professionals are allowed to purchase these products, which makes them hard to price in general.

The second most important cost factor to note when calculating gas pipe services is the average labor cost. Across the country, the hourly labor rates for plumbers vary considerably, ranging from $45 to $150 per hour. Check out local costs in your area, or get a quote from a professional plumber/gasfitter today to get a closer idea of the costs.

Why Install or Repair Gas Pipes?

Gas pipes are commonly used for a number of household appliances and systems, including, but not limited to:

  • Clothes Dryers
  • Ranges & Ovens
  • Home Heating Systems
  • Water Heaters 

When adding any of these appliances or upgrading systems from another energy source to gas, it’s necessary to add in new gas lines or to add a branch off existing HVAC lines to the new appliance/system. This is usually the most expensive type of gas piping work, particularly if no lines currently exist in your home.

Repairs, on the other hand, take place when there’s a leak or malfunction in the existing gas line. Signs that you require gas pipe repair include a rotten egg or sulfur smell, a blowing or hissing sound near one of the pipes or a fire or explosion near a pipeline. Age and natural disasters can also lead to the need for gas pipe repair, particularly if the pipeline is underground. Exposed pipeline or dead grass and vegetation around an underground line are signs that something might be wrong.

Finally, regular maintenance of your gas line is also important, so file this under the “repair” category. Whether or not there’s a problem, it’s a good practice to have a technician from your gas company or a licensed plumber/pipefitter check the entire line for leaks and overall integrity at least once per year.

DIY or Hire A Pro?

When some homeowners read about the steps needed to repair or even install gas piping — a process that primarily boils down to screwing together component parts — they figure that it’s an easy DIY job. However, the actual processes to repair and install gas pipes are much more exact, and, more importantly, have very little room for error. In fact, failure to properly seal and maintain a gas line isn’t only equivalent to inviting damage and further problems; it can literally destroy your home.

Liquid propane and natural gas are incredibly volatile and flammable. A leaking pipe can quickly become an explosion, causing damage and injury that aren’t at all worth the cost savings of a DIY repair or installation job.

Gas Pipe Installation Considerations

For safety reasons alone, it’s critical to have a professional install and repair your gas piping. However, if you’re questioning the need for a pro, consider that, to complete this job without risk, all of the following considerations must be met:


You must be able to purchase piping materials and fittings specifically designed to carry gas. These are not the same as, say, plumbing pipes. In order to reduce liability and promote safe installation, many states and municipalities refuse to sell these component parts to anyone other than licensed plumbers.

Even if you’re able to purchase the right type of materials, there’s no such thing as a one-size-fits-all gas pipe installation or repair kit. Each home and system is different and must have pipes and fittings tailored to it, down to cutting the pipes to the correct lengths. Different appliances, for example, require pipes that provide precise levels of BTUs per hour. If the pipes provide too much, you risk explosion. If they provide too little, your appliance or system may not work.

System Testing

Finally, once everything is installed in your new gas pipe system or all components are replaced via a repair, precise assessment of that system through an air pressure test is necessary to ensure that the seals are adequate to prevent a gas leak. Completing these tests is entirely up to you. The equipment can be difficult to obtain, and many companies won’t test systems or provide the equipment to do so if they haven’t installed or repaired the lines themselves. They simply inspect and provide a passing or failing grade.
