Gas Line Repair and Installation in Meridian, Idaho
Gas work is the one area of plumbing where there is no acceptable margin for error. Every line we install or repair is pressure tested before it goes into service.
What gas line work covers
What should I do if I smell gas?
Leave the building immediately. Do not switch anything on or off, including light switches, and do not use your phone inside. Electrical switching creates the exact spark an ignitable gas mixture is waiting for.
Once you are outside and away from the building, call your gas utility’s emergency line or 911 from there. Do not go back in for any reason until the utility says it is safe. Utilities respond to reported gas odours as an emergency and there is no charge for being cautious.
Once the utility has made the situation safe, that is the point at which a licensed plumber repairs the line and pressure tests it before it goes back into service.
Gas piping is licensed work in Idaho for a straightforward reason: the consequences of getting it wrong are fire, explosion and carbon monoxide. It is regulated under the same framework as the rest of plumbing, administered through the Idaho Division of Occupational and Professional Licenses.
Repairs cover corroded sections, failed fittings, damaged buried lines and connections that have loosened. Corrosion is the common one on older steel pipe, particularly where a line passes through a slab or runs underground.
New installation is the larger share of what we do, and most of it is driven by adding something. A gas range in a kitchen that has only ever had electric. A gas dryer. A firepit or outdoor kitchen on the patio. A standby generator. A pool or spa heater. Each of these adds load to a system that was sized for what the house had when it was built.
Sizing is where most of the engineering sits. Every appliance has a BTU demand, and the pipe has to be large enough to deliver the total simultaneous demand at adequate pressure, accounting for the length of the run and every fitting along the way. Adding a high-demand appliance to an undersized line does not usually produce a dramatic failure. It produces appliances that underperform, which is why the problem often goes unnoticed for years.

Request serviceSigns of a gas problem you should act on
The first item on this list is an emergency. Leave the building first and call from outside.
- A sulphur or rotten egg smellNatural gas is odourless, so an odorant is added specifically so you can detect leaks. Leave the building, then call the utility from outside.
- A hissing sound near a gas line or applianceTreat exactly as above. Leave first, call from outside.
- Dead or discoloured vegetation in a line over a buried gas runA classic indicator of an underground leak, often the only visible sign.
- Bubbling in standing water above a buried lineGas escaping and rising through the water.
- Higher gas bills with no change in usageCan indicate a small leak somewhere in the system.
- Yellow or lazy burner flames instead of crisp blueIncomplete combustion, which produces carbon monoxide. Worth immediate attention.
- Appliances that underperform, especially several at onceOften an undersized gas line rather than faulty appliances.
- Visible rust or scaling on exposed gas pipeCorrosion at the surface usually means more of it where you cannot see.

Request serviceHow gas line work is done properly
Four things happen on every gas job, without exception.
Load calculation first. Before any pipe is run, we total the BTU demand of every appliance the line will serve, then size the pipe for the full run length and fitting count. This is the step that gets skipped on cheap work, and it is the reason people end up with a range that will not hold a high flame while the water heater is running.
Correct materials. Black steel, corrugated stainless tubing and polyethylene for buried runs each have their place and their restrictions. Corrugated stainless in particular has specific bonding requirements under the electrical code, which is a detail that gets missed surprisingly often and matters for lightning-induced damage.
Pressure testing. Every new or repaired line is isolated and held under test pressure, and the pressure has to hold. Not a soap bubble check on the visible joints, an actual documented pressure test of the section.
Permits and inspection. Gas work is permitted work in the jurisdictions we serve. We pull the permit and schedule the inspection.
- Whole-system load calculationEvery appliance counted so the line is sized for real simultaneous demand.
- Appliance connectionsRanges, dryers, water heaters, furnaces, fireplaces, pool and spa heaters.
- Outdoor gasFirepits, outdoor kitchens, patio heaters and barbecue stub-outs.
- Generator supplySizing and running gas for a standby generator, coordinated with the electrical side.
- Leak location and repairTracing and repairing leaks on existing systems, including buried lines.
- Documented pressure testEvery line held under test before it is put into service.

Request serviceGas piping materials and where each is used
Material choice is dictated by where the pipe runs and what the code allows, not by preference.
| Material | Typical use | Key considerations |
|---|---|---|
| Black steel pipe | The traditional standard for interior gas distribution | Durable and widely accepted. Threaded joints, heavier to work with, and it can corrode where it passes through masonry or soil |
| Corrugated stainless steel tubing | Flexible interior runs, especially in retrofit work through finished spaces | Fast to install through existing framing. Has specific electrical bonding requirements that must be followed |
| Polyethylene | Buried exterior runs to detached structures, generators and outdoor kitchens | Made for direct burial and will not corrode. Must transition to an approved material above ground |
| Copper | Restricted, and dependent on local amendments | Permitted only in some jurisdictions and only in certain conditions. We check local requirements rather than assume |
Idaho enforces the Uniform Plumbing Code, and individual cities publish their own amendments on top of state code. We work to whichever applies to your address.

Request serviceHow a gas line job runs
If you have a suspected leak, stop reading and call from outside the building first.
Tell us the scope
A leak, a new appliance, an outdoor kitchen or a generator. Emergencies are handled differently from planned installations.
Assessment and load calculation
We look at your meter, existing line sizes and total appliance demand, then determine what the new work needs.
Permit and written quote
You see the price before work starts. We pull the permit where your jurisdiction requires one.
Installation or repair
Correct material for the location, properly supported, with shutoffs where the code requires them.
Pressure test and inspection
The line is held under test pressure, the inspection is scheduled, and the system is only put into service once it passes.
Same day and next day appointments are available across the valley.
Request serviceGas in the Treasure Valley
Natural gas service across southern Idaho is supplied by Intermountain Gas, which serves several hundred thousand customers across the region. If your home is inside the service territory and already has a meter, adding appliances is usually a matter of confirming your existing line and meter can carry the additional load.
Meridian has grown more than 260 percent from its year-2000 population and is now Idaho’s second largest city, with about 60 percent of its housing units built after 2000. That has a direct consequence for gas work. Homes built during the valley’s growth years were piped for the appliances they were sold with, typically a furnace, a water heater and often a range. Everything added since, and outdoor living in particular, is load the original design never accounted for.
Outdoor gas is the single most common request we get here. The valley’s long dry summers and cool evenings make patios genuinely usable most of the year, and firepits, outdoor kitchens and patio heaters have gone from luxury to standard in newer neighbourhoods around Eagle, Star and north Meridian.
Idaho enforces the Uniform Plumbing Code rather than the International Plumbing Code, and the electrical side runs on the National Electrical Code, both administered through the Idaho Division of Occupational and Professional Licenses.

Request serviceWhat gas line work costs
Quoted after assessment, agreed before work starts. Gas jobs vary enormously depending on the run.
- Length and route of the runThe dominant factor. A stub-out near the meter is a small job; a run to the far corner of a property is not.
- Whether it can be run through open spaceAccessible attics and crawl spaces are straightforward. Routing through finished walls and ceilings takes far longer.
- Buried or above groundBuried runs to detached structures need excavation, approved materials and proper transitions.
- Whether the existing line needs upsizingAdding a high-demand appliance sometimes means the supply from the meter has to grow too.
- Permit feesSet by your city or county and passed through at cost.

Request serviceFrequently asked questions
What should I do if I smell gas in my house?
Leave immediately and take everyone with you. Do not operate any electrical switch on the way out, including light switches, and do not use your phone inside the building. Once you are outside and clear of the property, call your gas utility’s emergency number or 911. Do not go back inside until the utility tells you it is safe. There is no charge for reporting a suspected leak, and utilities treat these calls as emergencies.
Do I need a permit to run a gas line in Meridian?
In the jurisdictions we serve, gas piping work requires a permit and an inspection. Idaho enforces the Uniform Plumbing Code through the Division of Occupational and Professional Licenses, and cities in the valley add their own requirements on top. We pull the permit and schedule the inspection as part of the job. Permit fees are set by the city or county and passed through at cost.
Can I run a gas line myself?
Gas piping is licensed work in Idaho, and for good reason. Beyond the legal position, an unpermitted gas line that has not been pressure tested is a genuine hazard to everyone in the building, and it will almost certainly cause problems with insurance and at the point of sale. This is one area where doing it yourself is not a reasonable risk to take.
How much does it cost to add a gas line for a firepit or outdoor kitchen?
The main variable is the distance from the existing supply and whether the run can go through accessible space or has to be buried or routed through finished areas. A stub-out close to the meter is a modest job. A run to the far side of a property, buried, with a new tee off an upsized supply, is a much larger one. We quote after looking at the route.
How do I know if my gas line is big enough for a new appliance?
It is calculated rather than guessed. Every gas appliance has a BTU rating, and the pipe has to deliver the total simultaneous demand at adequate pressure over the actual length of the run, accounting for every fitting. Adding a high-demand appliance such as a tankless water heater to a line sized for a conventional tank is the classic error, and the symptom is not a dramatic failure but appliances that quietly underperform.
How often should gas lines be inspected?
There is no universal schedule for residential gas piping, but there are sensible trigger points: whenever you add or replace a gas appliance, if you notice any of the warning signs on this page, before buying a home, and after any significant excavation on the property. Appliance-level combustion checks are a different matter and should happen annually as part of heating maintenance.
Do you install gas lines for standby generators?
Yes. A standby generator needs both a properly sized gas supply and the electrical work to connect it through a transfer switch. The gas side is usually a substantial load that has to be accounted for in the whole-house calculation, and the run is often buried out to where the generator sits. We handle both sides of that job.
