gas line to house

$15 – $25 Per Foot

It will generally cost the homeowner between $15-$25 a linear foot to install a gas line from the street to the gas meter at your home. The work includes trenching the ground, installing the line to the meter and gas main, then backfilling the trenched or excavated area.

Average Cost of Gas Line Service from Street

Homeowner’s cost to run a gas line from the street to the house averages between $700 and $1,250, or $15 to $25 per foot. However, there are a few variables.

For example, some natural gas companies will run the line from the street to the home for free, as long as the line is 100 feet or less. The utility wants you to become their customer when, for example, converting to propane after their natural gas line is run past your home. In such cases, the $15 to $25 per foot kicks in after the first 100 feet – or it could be 50 or 75 feet. Gas companies have various standards.

These costs might include meter installation, but again, it varies by locality. It doesn’t include running gas line within the home to gas appliances or hooking up gas appliances. Those are separate projects often done by a plumber rather than the utility company.

Overview of Gas Line Installation

In most areas, natural gas (NG) is significantly cheaper than propane (LP). When building a new home, it might be attractive to take the cheaper route of having a propane company set a tank in your yard and run a gas line to the house. However, your short-term gains would be lost in as short as 3-5 years depending on the relative prices of the two gases and how much you use.

When converting your home from using propane to natural gas, the cost is usually recouped in less than 10 years through the lower price of NG. And once you complete this project, you can get on with other common indoor home improvements that make your dwelling more livable. Several of them, with price information, are listed below.

This page of Business Finance News is heavy on pricing and includes cost factors to help narrow your estimate – Gas line length, size of the pipe, local ground conditions and more. We’ve added a few estimates from other trustworthy estimating sites for you to compare.

And there is an option below for you to share a few details about your gas line installation project and your cost for the benefit of other readers. If interested, please bookmark this page of Business Finance News and return to share the information once your project is complete.

Gas Line Installation Cost Factors

These factors are designed to give you a better idea of where on the gas line installation cost spectrum your estimate might fall.

  • Length of Gas Line – The first 50 to 100 feet from the street to the house might be free – or it might not be – and the local gas company will install it.  Any distance over the “free” portion will be charged. Again, this depends on the actual gas company, site conditions, and where the home is located.
  • Difficulty of Installation – As you can imagine, trenching through stone, rocky soil, dry clay or a heavily treed lot takes more time and is harder on equipment, so costs more, than working in softer soils. If you need to remove trees or dig up stumps, you’ll need to address that first.
  • Type of Line Used – There can be a big cost factor if you have an option for pipe material used from the street to the home. See Retail Costs below for an overview of the type of gas lines used and their costs.
  • First Line or Additional Line – While rare, adding a second line  occasionally happens when the existing line doesn’t have enough gas carrying capacity to meet the home’s demand. This occurs mainly in older homes and in very large homes, perhaps when an addition like a gourmet kitchen or bedroom suite is added with 2+ gas appliances. We heard from one reader who bought an older home, saying, “When the gas water heater is running, there is noticeably less gas available at the gas range.” They need to replace the existing line with a larger one – or add a second line.
  • Permit Cost – The cost of a permit and inspection is paid upfront by the utility, but you’ll pay for it in the end. Permits start at about $100 per line. We break down permit and inspection costs below.
  • Gas Pipe Removal – If an old or damaged gas pipe is being replaced, the gas company will charge $5 to $8 per foot for the removal and disposal of the old gas pipe. You might be able to save some of that cost by having the gas company leave the old line in your yard if you have the means to cut it into lengths and take it to recycling.
  • Where You Live – Labor costs vary by the general cost of living in your area. Other “local” factors include how far off the road homes are set in your neighborhood, soil conditions and how badly your local government needs cash from permits and inspection fees.

Retail Gas Line Cost – Pipe and Supplies

Since the local natural gas company will most likely install the new gas line from the street to the home, there are not many supplies that are needed. The main and most obvious supplies needed are the gas pipe, tools, and pipe tape.

If you have pipe material options, your gas company will offer them when providing you an estimate of the cost to run gas line to your home. Consider durability and the possible need to replace the line “down the road” for you or a new owner.

  • $5 – $8 per Foot | Black Iron Pipe. The most common pipe used to install a natural gas line is black iron pipe. It stands the test of time much better than the other types listed above. However, in areas prone to earthquake, it might be ruled out due to its lack of flexibility. Where used, it lasts 100+ years.
  • $4 – $10 per Foot | Galvanized Steel Pipe. This durable material resists corrosion and has a lifespan of 75-100 years.
  • $2 – $4 per Foot | CSST (corrugated stainless steel tubing). Used most commonly in earthquake zones due to its flexibility, CSST is good for 50+ years depending on soil conditions.
  • $2 – $4 per Foot | HDPE or High-density Polyethylene. This pipe won’t corrode and is resistant to cracking. Sem-flexible – it lasts up to 50 years.
  • $3 – $6 per Foot | Copper Pipe – Price is quite variable due to the fluctuating cost of copper. Copper is mainly used for propane and lasts less than 50 years.
  • $25 – $100 | Large Adjustable Wrench

Permits, Inspection, Related Costs and Installation Time

Permits and Inspection Cost

  • $100 – $200+ |  Many cities require a permit to install a gas line from the street to the home.  The average cost for a permit is $100, but they can vary from city to city.  After the gas line is installed, the city will then have to inspect the new gas line, which can cost between $50 and $100.  The purpose of this is to ensure that the line is correctly installed and there are no leaks.

Related Costs

As noted, the cost of installing street service, i.e. gas line from the street to your home, is $15 to $25 per foot with an average of about $20. HomeGuide puts average cost at $12 per foot, but our statistics show that’s possible for some jobs, but not for most. Fixr says total possible cost is $60 per foot, and that’s probably possible in extreme conditions like mountainous terrain, but your job won’t likely get close to that number.

Once your new gas line is run from the street to your home, you’ll be able to tackle additional projects that will give your home the warmth, utility and comfort you desire. With these, there will be extra costs. Some of which might be:

  • The Cost to Run a Gas Line Within the House – $20 – $26 per linear foot. The gas company does the work outside. The gas line inside the house from the meter to various appliances brings with it plumber costs. Total cost is typically between $650 and $900. Home Advisor suggests a maximum cost of about $815, which is in the ballpark.
  • The Cost to Hook Up a Gas Appliance – $150 – $300 for most common appliances. If your appliances are in place, then a plumbing contractor can hook them up and include the cost in the total estimate for a gas line and appliance hookup. You’ll save a little on total plumber costs when multiple jobs are done in the same visit.
  • The Cost to Install a Gas Shut Off Valve – $350 – $550 per valve. This is another job a plumbing contractor can do at the time of running a gas line and handling gas appliance installation. If so, cost will be lower than if this is a stand-alone job.
  • The Cost of a New or Replacement Gas Furnace – $3,000 – $4,500. Once the gas infrastructure is in place, you can complete the installation of a furnace, gas boiler, free standing gas fireplace ($950 – $3,500 based on the fireplace cost) or gas log fireplace (about $1,350) and other equipment to keep your home comfortably warm. Furnace cost varies by size, efficiency, performance level and installation factors.
  • Tree Removal – $50 – $1,500 per Tree. If you have to have trees and stumps removed, plan on an extra few days in front of the gas line installation to have it done as well as up to $1,500 per tree.

Other Costs and Installation Time

Running a new gas line from the street to the home is a relatively fast job.  Your local natural gas company has all the equipment and expertise.

  • 2-4 Hours | Time depends on length, the site conditions and where the new natural gas has to run.  Often there will be extra time and cost if the line has to go under or around existing barriers, such as driveways, garages, swimming pools, etc.

DIY or Hire a Pro?

This is a job that could save you a lot of money in the long run if you’re currently on propane, since natural gas is generally cheaper. In short, it is worth doing.

That being said, this is a project for your local natural gas company. First, a homeowner probably couldn’t get the permit to do it. And that’s pretty much the end of that.

Even if you could, there are safety issues when working with gas, the need for expertise in trenching and laying the pipe so that it is well supported.

Finally, your local gas company might run 50-100 feet of it free, so there would only be costs, no savings, by DIY.
