When homeowners in Clayton need gas line work, the question is almost always the same: "Who do I even call for that?" The answer is Pro Maxx One. Gas is what we know best — not a side service we picked up, not something we quote over the phone with a guess. Our owner Eric spent nearly three decades working inside the gas utility before founding this company, and that background changes everything about how we approach a job.


We handle the full scope of residential and commercial gas work: new gas line installation, repairs, leak detection, appliance hookups, outdoor kitchen and fire pit lines, pool heater connections, propane services, and propane-to-natural-gas conversions. Every job includes permit pulling and code-required inspection coordination. You don't chase paperwork. We do.


We serve Clayton, Raleigh, Cary, Apex, and surrounding communities in Johnston County and beyond.

Gas Line Installation and Repair

We install and repair gas lines indoors, outdoors, and underground. Whether you're adding a gas range, extending a line to a new appliance, or dealing with an aging line that needs replacement, we assess the actual job before quoting — not from a price sheet over the phone.

Outdoor Kitchen, Fire Pit, and Grill Lines

Running gas to an outdoor kitchen, fire pit, or built-in grill is a different job than indoor work. Longer runs, different pressure calculations, weatherproof connections. We've done enough of these to know the details that matter.

Pool Heater Gas Lines

A pool heater demands a properly sized gas supply line. Undersized lines cause heaters to underperform or fail early. We size the line to the heater's BTU requirement and handle the full installation.

Gas Logs

Gas log sets need a properly installed dedicated line and the right valve configuration. We install new gas log systems and service existing ones — including pilot issues, valve replacements, and conversions.

Propane Services & Propane-to-Natural-Gas Conversion

We work with propane systems and handle full conversions from propane to natural gas when a home or property gains access to the natural gas main. Appliances, regulators, line sizing — we manage the whole transition.

Gas Leak Detection

If you suspect a gas leak, your first move is to leave the building and call 911 or your gas utility. Once the area is cleared and the utility has shut off supply, call us. We locate the source, make the repair, and coordinate the inspection before gas is restored.

⚠️If You Smell Gas Right Now⚠️

Leave the building immediately. Do not flip light switches, use your phone inside, or try to find the source yourself. Call 911 or your gas utility's emergency line from outside or a neighboring property. Once the area is cleared and supply is shut off, we're ready to help with the repair and inspection.

How We Quote Gas Work (and Why It's Different Here)

A lot of plumbers will quote gas line work over the phone. We don't, because a phone quote on gas work is a guess — and guesses lead to change orders or corners cut.


Before we quote, we walk the route. We look at where the line needs to go, what's in the way, how far it's running, and what the BTU load requirement is for the appliance or system being served. Then we give you a real number.


It takes a little more time upfront. It means no surprises on the back end.

Frequently Asked Questions About Gas Line Work

Straight answers that reflect our approach

  • Who installs gas lines in Clayton, NC?

    Pro Maxx One is a licensed gas plumber serving Clayton and surrounding Johnston County communities. Our owner Eric is widely known as the Gas Guru — he spent nearly 30 years working inside the gas utility before starting this company. We handle gas line installation, repair, leak detection, appliance hookups, and more.

  • Do I need a permit for gas line work in Johnston County?

    Yes. Any new gas line installation or significant repair in Johnston County requires a permit and a code-required inspection. Pro Maxx One pulls the permit and coordinates the inspection as part of every gas job — it's included, not an add-on.

  • How long does a typical gas line installation take?

    Most residential gas line installations are completed in a single day. More complex jobs — underground runs, outdoor kitchens, or whole-home propane conversions — may take two days depending on scope. We'll give you a realistic timeline when we quote the job.

  • What's the difference between indoor and outdoor gas line installation?

    Indoor lines run through conditioned space and typically use black iron or CSST (corrugated stainless steel tubing) per code. Outdoor and underground lines require materials rated for burial or exterior exposure, proper depth, and weatherproof connections. The permit and inspection requirements apply to both.

  • Can I convert my home from propane to natural gas?

    Yes, if your street has access to the natural gas main. The conversion involves replacing or reconfiguring the supply line, swapping out regulators, and converting each appliance's burner orifices for natural gas. We handle the full conversion — not just the line.

  • What are the signs of a gas leak at home?

    The most common signs are the smell of rotten eggs or sulfur (the odorant added to natural gas and propane), a hissing sound near a gas line or appliance, dead vegetation over an underground line, or unexplained increases in your gas bill. If you notice any of these, treat it as an emergency — leave the building and call 911 or your gas utility before calling us.
