Gas Line Installation Costs

Professionals & Services Cost Guides      Natural Gas      Gas Line Installation Costs

The first thing to know about installing a gas line is that it is not a project that anyone can do. This is a dangerous task and needs to be done by a licensed, trained professional. Whenever you install a new appliance, it is a good idea to also replace the gas line if it is more then five years old. Whether you need to fix a small section or run lines throughout the house will also affect what you pay for gas line installation.

Many people inquire about simply extending their gas lines because it seems like the easier and more affordable options. However, it is usually in your best interest to fully replace the lines just to make sure that you are able to use your home safely. Not only will a professional ensure that things are done correctly, but they may be the only one who can get the installation materials or certain dangerous pipes and products.

Typically, gas line installation costs will vary depending on the type of material chosen.

Item Unit Cost
Copper gas line- not for natural gas use $1-2 per linear foot
Black iron- no national quality standards $5-$8 per linear foot
Flexible CCST pipes $2-$4 per linear foot

Gas line installation 50 ft., labor, and mid-range materials.

Item Unit Cost Total Cost
New gas line $1-$8 per linear foot $50-$400
Other materials: connections, sealants, gas testing kits, etc. $1-2 per linear foot $50-$100
Labor (Plumber) $55 $110-$220
Total Cost   $210-$620

Other considerations and costs

  • Permits are almost always required for installing a new gas line. If you are digging for a line, you may also need to call the 811 line to have them check the ground for dangerous wires or other lines.
  • To protect your gas lines, you can install a PVC conduit, which covers the line like a sleeve. These are ideal for areas prone to natural disasters or lines running through high-traffic areas. These conduits cost $1-$3 per linear foot.
  • For better leak protection, a steel casing pipe can be installed around any gas pipes in your home. This is ideal for anything but PVC and will cost between $3 and $5 per linear foot.
  • If you have existing lines in place, you may be able to extend them at a cheaper cost than replacing the whole line or installing a new one.

DIY considerations

  • Unless you are a licensed plumber or other professional, you should never attempt to install your own gas lines. This work requires specialized tools and materials. Gas is flammable and explosive, after all, and you want to make sure that your home is safe.
  • Some home warranty and insurance companies may void your coverage if you do the work yourself on something like a gas line installation. Be sure to check all the details to ensure that this doesn’t happen to you.
