Gas Piping Services - Safe, Licensed Gas Line Installation & Repair

Need a gas line for a new stove, dryer, or water heater? Express Plumbing handles gas piping installation and repair across Lake Saint Louis, Wentzville, O'Fallon, and St Charles County. We test every connection and pull permits when required. Licensed master plumber with 26 years experience. Call (314) 807-8460 — gas work done right.

Gas piping isn't something to DIY or trust to someone without a license. If a gas line isn't installed correctly, you're dealing with gas leaks that can cause explosions or carbon monoxide poisoning. This is serious work that requires proper licensing, the right materials, and testing to make sure every connection is tight. Jim's a licensed master plumber in St Charles County, St Louis County, and the City of St Louis. We're bonded and insured specifically for gas work. We pull permits when they're required and our installations pass inspection the first time.

Most of our gas piping work is for new appliances — running a gas line to a new stove, dryer, tankless water heater, or gas fireplace. We also do repairs on existing gas lines, replace old corroded pipe, and install gas lines for outdoor grills or fire pits. Every gas line we install gets tested for leaks before we're done. We use proper black iron pipe or CSST (corrugated stainless steel tubing) depending on the application and code requirements. We size the pipe correctly so your appliance gets the gas flow it needs. And we make sure everything's to code so it passes inspection. Gas work isn't something to cut corners on. Call us at (314) 807-8460 and we'll do it right.

WHY HOMEOWNERS CHOOSE Express Plumbing for Gas Line Installation

Licensed and Insured for Gas Work

Jim holds a master plumber license in St Charles County, St Louis County, and the City of St Louis. We're licensed specifically for gas work, which means we're allowed to install and repair gas lines in your home. We carry full liability insurance and workers' comp that covers gas piping work. That matters because if something goes wrong, you're protected. A lot of handymen or unlicensed contractors will offer to run a gas line cheap. Don't do it. If they mess it up and your house explodes, your insurance won't cover it because the work wasn't done by a licensed professional.

We Pull Permits and Pass Inspection

Gas line work requires permits in most jurisdictions. We pull the permits, we do the work to code, and we schedule the inspection. Our gas piping installations pass inspection the first time because we follow code and we don't cut corners. That means proper pipe sizing, right materials, correct fittings, proper support, and tested connections. Inspectors check all of this. If it's not done right, you fail inspection and you're paying someone else to fix it. We've been pulling permits for gas work since 1999 and we know what passes.

We Test Every Connection for Leaks

After we install a gas line, we test it before we're done. We pressurize the line and check every connection with leak detection solution. If there's a leak, bubbles form and we fix it immediately. We don't leave until every connection is tight and there are no leaks. That's how you know the work is safe. Some contractors will run a gas line and not test it. You won't know there's a leak until you smell gas or your gas bill goes up. We test everything because that's the right way to do gas work.

26 Years of Gas Piping Experience

We've been running gas lines and doing gas piping work across Lake Saint Louis, Wentzville, O'Fallon, St Peters, and surrounding areas since 1999. That's over two decades of gas line installations, repairs, and replacements. We've worked in old homes with outdated gas systems and new homes with modern setups. We know how to deal with tight spaces, tricky runs, code requirements, and all the challenges that come up during gas work. Experience matters when you're working with something that can be dangerous if it's not done right.

Our Simple 3-STEP Gas Line Installation PROCESS

1

We Assess Your Setup and Plan the Run

When you call (314) 807-8460, we'll ask what you need — gas line to a new stove, dryer, water heater, outdoor grill? We come out, look at your existing gas system, and figure out the best route to run the new line. We make sure your gas meter and existing lines can handle the additional load. We'll tell you what needs done, how long it'll take, and what it'll cost before we start.

2

We Install the Gas Line to Code

We run the gas line from your existing supply to where your appliance goes. We use the right pipe type and size for the application — black iron pipe for most indoor runs, CSST for flexible installations where code allows. We install shutoff valves where required, support the pipe properly, and make all connections tight. If permits are required, we pull them before we start. Most gas line runs take a few hours to half a day depending on the distance and complexity.

3

We Test for Leaks and Pass Inspection

Once the line is installed, we pressurize it and test every connection with leak detection solution. If there's a leak, we fix it. Once we're confident there are no leaks, we call for inspection if required. Our work passes inspection because we follow code. Once the inspection passes, you can connect your appliance and you're good to go.

Frequently Asked Questions

Got Questions? We’ve Got Answers!

How much does it cost to run a gas line?

It depends on how far we're running it and what's involved. A simple 10–20 foot run to a new appliance in the same room as your existing gas supply might cost $300–$600. A longer run across the house or to a second floor might cost $600–$1,200. Outdoor gas lines cost more because we're running pipe through walls and underground. We give free estimates so you'll know the price before we start.

Do I need a permit for gas line work?

Usually, yes. Most jurisdictions require permits for gas line installations. We pull the permits, we do the work, and we schedule the inspection. You don't have to deal with any of that — we handle it. The permit and inspection exist to make sure gas work is done safely and to code.

Can you run a gas line to my outdoor grill?

Yes. We run gas lines to outdoor grills, fire pits, and patio heaters all the time. We'll run a line from your house to your patio or deck, install a shutoff valve, and cap it so you can connect your grill. Most outdoor gas lines take half a day to a day depending on the distance and what's involved. No more dealing with propane tanks.

What's the difference between black iron pipe and CSST?

Black iron pipe is rigid steel pipe that's been used for gas lines for decades. It's durable and code-approved everywhere. CSST (corrugated stainless steel tubing) is flexible tubing that's easier to run through tight spaces and around obstacles. It's approved by code in most areas but not all. We'll use whichever one makes sense for your installation and is allowed by local code.

Can you replace old galvanized gas pipe?

Yes. Galvanized pipe corrodes over time and eventually starts leaking. If your home has old galvanized gas pipe, replacement is a good idea before you have a problem. We replace it with black iron pipe or CSST, test everything for leaks, and you've got a safe gas system. Most galvanized pipe replacements take a day or two depending on how much pipe we're replacing.
