Gas Line Installation Services
Adding a new gas appliance to your home, such as a professional-grade gas range, a high-efficiency tankless water heater, or an outdoor fire pit, requires more than just hooking up a hose. The gas plumbing system must be carefully engineered. If a new pipe is run without properly calculating the BTU (British Thermal Unit) demand of all the appliances on that line, you will suffer from "gas starvation." This causes appliances to underperform, pilot lights to go out, and creates severe safety hazards.
Professional gas line installation ensures the correct pipe diameter is chosen and routed safely. We work with rigid black iron pipe for exposed areas and flexible CSST (corrugated stainless steel tubing) for complex routing through walls and joists. Every installation includes the necessary shutoff valves, sediment traps, and rigorous pressure testing to guarantee the system easily passes municipal inspections and provides decades of safe, reliable fuel delivery.
Signs You Need Gas Line Installation
- You are converting your kitchen from an electric stove to a gas range.
- You are upgrading to a tankless water heater, which requires a much larger gas supply line.
- You want to run a permanent gas line to your patio for a grill, eliminating the need for propane tanks.
- You are installing a whole-home backup generator that runs on natural gas.
- You are finishing a basement and adding a new gas fireplace.
Our Process
BTU Load Calculation
We calculate the total gas demand of the new appliance and your existing ones to ensure the main line can handle the load.
Permitting
We secure the necessary municipal permits required for running new gas lines.
Pipe Routing and Installation
The new pipe is cut, threaded, and routed safely through the home, installing shutoff valves and sediment traps at the appliance.
Pressure Testing and Sign-Off
The new line is capped and pumped with air to test for pressure drops, followed by a final city inspection.
What Affects the Cost
- The length of the new pipe run (distance from the main trunk line to the new appliance).
- The required pipe diameter (larger pipes needed for high-demand appliances like tankless heaters cost more).
- The routing complexity (trenching for an outdoor fire pit or navigating finished basement ceilings).
- Cost of municipal permits and inspections.
✓ Safe to DIY
- Researching the BTU requirements of the new appliance you wish to purchase.
- Clearing the path in the basement or yard where the new pipe will need to be run.
✕ Stop & Call Us
- Using unapproved materials like PVC, standard water copper, or cheap flex-lines to run permanent gas lines.
- Connecting a new appliance yourself without installing a dedicated shutoff valve and drip leg (sediment trap).
Frequently Asked Questions
Can you run a gas line outside for a grill?
Yes. We run specialized underground-rated gas piping from your house to your patio or outdoor kitchen, so you never have to swap out a heavy propane tank again.
What is a sediment trap (drip leg)?
A sediment trap is a small T-fitting installed just before the appliance. It forces the gas to change direction, causing any moisture or debris in the gas line to drop into the trap rather than entering and destroying the appliance's delicate gas valve.
Do I need a permit to install a new gas line?
In almost all municipalities, yes. Gas work is heavily regulated due to the severe fire and explosion risks. A permit and final inspection ensure the work was done to code.
