Gas Line Installation and Repair in Middle Tennessee
- Licensed and insured plumbing, HVAC and electrical techs
- Tennessee Limited Licensed Plumber 5279
Adding a gas range, a tankless water heater, a standby generator or an outdoor kitchen? Each one needs a gas line sized for the appliance and run safely from the meter to where the appliance sits.
We'll look at what's there now, work out what the new line needs, and give you a firm price before any work starts. New and repaired lines are pressure tested before they go into service. If you ever smell gas, the steps on this page come first: get out, then call.
Signs you need gas lines help
- A rotten egg smell near an appliance, the meter or a line (leave the house first)
- A hissing sound near a gas line or an appliance connection
- You're adding a gas appliance, generator, fireplace or grill
- You're switching from an electric range, dryer or water heater to gas
- A new tankless water heater needs more gas than the old tank did
- Old, corroded gas pipe, or an old flexible connector behind an appliance
- Dead or dying plants over a buried gas line
- A remodel or addition that moves or adds gas appliances
What we do
New lines for appliances
Gas lines for ranges, cooktops, dryers, water heaters and fireplaces, sized for the appliance and the rest of the gas load in the house.
Tankless water heaters
A tankless unit often needs more gas than a tank heater did, so the line from the meter may need to be larger. We size it for the new unit.
Generators and outdoor kitchens
Gas lines to standby generators, grills, outdoor kitchens and fire pits, run and protected to code outside the house. A generator's electrical connection is done by licensed and insured techs.
Gas line repair
Finding and repairing leaking fittings, corroded pipe and damaged lines, and replacing old appliance connectors.
Pressure testing
Testing new and repaired lines under pressure before they go into service, as the code requires, and checking each connection for leaks.
New construction and renovations
Gas piping rough-in and trim-out for new homes, additions and remodels, coordinated with the HVAC and electrical so appliances, venting and power line up.
Repair or replace?
A leak at one fitting or a worn appliance connector is a repair. We fix it, test it and put the line back into service.
Replacing a run of pipe makes more sense when it's corroded along its length, when old pipe runs somewhere it can be damaged, or when it's too small for what you want to add. We'll explain what we found and give you the price of each option before any work starts.
What it costs, and how we price it
What drives the price
- How far the line runs from the meter, and the route it takes
- The pipe size the appliance needs, based on its gas demand and the rest of the house
- Whether the line runs inside, through a crawl space or attic, or underground outside
- Whether the meter or regulator needs changes, which involves the gas company
- How many appliances are being added or moved
- Permits and inspections the local jurisdiction requires

Urgent
Smell gas?
- Leave the house now, and take everyone with you.
- Don't flip light switches, unplug anything or use a flame on the way out.
- Once you are outside and away from the house, call your gas company or 911. For propane, call your propane supplier or 911.
- Then call us at (615) 426-9344.
We work Monday to Friday, 8 a.m. to 5 p.m.. Outside those hours, shut off what you can, stay safe, and call or text first thing.
What should I do if I smell gas?
Leave the house first, and take everyone with you. Don't flip light switches, unplug anything or use a flame on the way out. Once you're outside and away from the house, call your gas company or 911. For propane, call your propane supplier or 911.
Don't go looking for the leak yourself. After the gas company or the fire department says it's safe, call us to find the problem and fix it.
Why does a tankless water heater need a bigger gas line?
Because it burns much more gas at once. A tank heater warms water slowly over time, so it needs a modest amount of gas. A tankless unit heats water as it flows, which takes far more gas the moment you open the tap.
A line sized for the old tank often can't deliver that. The line, and sometimes the meter, has to be upsized. We check that before we price the job.
Can I switch from an electric range or dryer to gas?
Usually, if the house has natural gas service. It takes a new gas line to where the appliance sits. We also check whether the gas piping and the meter can carry the added load along with everything else already on the line, like the furnace and water heater.
What is the yellow flexible gas tubing in my house?
It's likely corrugated stainless steel tubing (CSST), used in many newer homes. Manufacturers and the fuel gas code require it to be bonded to the home's electrical grounding system, which lowers the risk of damage from a nearby lightning strike. If you're not sure yours is bonded, ask us to look when we're out.
Common questions
I smell gas. Should I call you first?
No. Leave the house first, then call your gas company, propane supplier or 911 from outside. Once they have made it safe, call us at (615) 426-9344 to find and repair the problem. We work Monday to Friday, 8 a.m. to 5 p.m.
Is the diagnostic visit really free?
Yes. We'll come look at what you have and what you want to add for free, and give you a firm price before any work starts. You decide from there.
Do you run gas lines for generators?
Yes. We run gas lines to standby generators, sized for the generator and the other gas appliances in the house. The electrical connection is done by licensed and insured techs, so one call covers it.
Do I need a permit for a new gas line?
Usually. New gas piping generally needs a permit and an inspection, and the line has to pass a pressure test. Requirements depend on the city or county. We'll tell you what your job needs when we give you the price.
Can you move a gas line for a kitchen remodel?
Yes. Moving or extending gas lines for a new range location, an island cooktop or an added appliance is common in renovations, and renovations are work Root House specializes in.
Are old flexible gas connectors a problem?
Some are. Older uncoated brass connectors, used behind appliances years ago, can crack at the fittings. If yours is old or you are not sure, we can check it and replace it with a new coated connector.
How do you check a gas line for leaks?
New and repaired lines are pressure tested: the line is sealed, pressurized and watched on a gauge to confirm it holds. Individual fittings are checked with a leak detection solution.

Plumbing
Tank or tankless: which water heater fits your home?
A tank water heater costs less to install but can run out of hot water. A tankless unit heats water as it flows, so it won't run out. It costs more, though, and can only heat so much at once. If your tank keeps up, another tank usually fits. If you keep running out, tankless is worth pricing.
Electrical
What size generator does a house need?
Size a generator to what has to run at the same time. Add up the running watts, then allow for the extra surge the biggest motor pulls to start. Covering the fridge, lights and a well or sump pump takes a much smaller generator than adding central air or electric heat.
Work that holds.
