Thinking about adding a gas stove, outdoor grill, or fireplace? A new gas line can make your home more efficient and more enjoyable, but most homeowners want to know one thing first, what’s it going to cost?
The short answer, it depends. Gas line installation costs can vary quite a bit based on your home, the distance, and what you’re connecting.
Below, we’ll break it down so you know what to expect before getting started.

Gas Line Installation Cost in Denver
For most homes, gas line installation typically falls between:
Project Cost:
- $800 to $3,000 for most gas line installations
- Smaller jobs: $300 to $800
- Larger or complex projects: $2,000 to $5,000+
Per Foot:
- $20 to $40 per linear foot on average
- More complex installs can reach $40+ per foot
Smaller jobs, like hooking up a gas stove, will be on the lower end. Larger projects, like running a new line across the house or yard, will cost more.
Residential Gas Line Installation Cost Per Foot
One of the biggest cost drivers is distance.
Most homeowners in Denver can expect:
- $20 to $30 per foot for simpler installs
- $30 to $40+ per foot for more complex jobs
Why the range?
- Easier access = lower cost
- Tight spaces, walls, or trenching = higher cost
- Material choice also plays a role
This is why two homes can have very different estimates, even for similar projects.
Cost to Replace a Gas Line
If you’re replacing an old or damaged gas line, costs are usually higher than a new install. That’s because removal, upgrades, and code compliance all add time and complexity.
Typical range:
- $1,000 to $5,000+
Factors that impact replacement cost:
- Age and condition of existing pipes
- Whether walls or floors need to be opened
- Code upgrades required to meet current standards
In many Denver homes, older gas lines may need full or partial replacement to stay safe and up to code.
Cost to Extend or Move a Gas Line
Need to relocate a gas line or run one to a new appliance? The cost to extend or move a gas line depends on distance, access, and how complex the routing is.
Here’s what to expect:
- Extending a gas line: $300 to $1,500
- Moving a gas line: $500 to $2,000+
This depends on:
- Distance from the existing gas line
- Whether the line runs through walls, floors, or outdoors
- Accessibility and labor required
- Permits and inspections
Simple extensions, like adding a line for a grill or stove, are usually on the lower end. Moving a gas line inside finished spaces or across longer distances will increase the cost.
Cost to Install Gas Lines for Appliances
Some of the most common installs include:
- Gas stove: $400 to $1,200
- Outdoor grill: $300 to $900
- Fireplace: $1,000 to $2,500
These are typically smaller jobs, but they still require proper sizing and pressure testing to be done safely.
What Impacts the Cost Most?
A few key things will influence your final price:
- Length of the gas line
- Type of piping used
- Labor and installation complexity
- Permits and inspections
- Accessibility inside your home
Gas line work isn’t something to cut corners on. Proper installation keeps your home safe and ensures everything runs efficiently.
Why Professional Installation Matters
Gas lines are not a DIY project. Even a small mistake can lead to serious safety risks, including leaks or carbon monoxide exposure.
Working with a licensed professional means:
- Proper permits and inspections
- Safe connections and pressure testing
- Code-compliant installation
It’s the kind of job you want done right the first time.
