Gas Line Repair & Installation

When to Call — Gas Leak Warning Signs

Natural gas has no smell by itself — the “rotten egg” odor comes from mercaptan, added for  safety.  

If you notice that smell, take it seriously. 

Other red flags: 

• Hissing sound near an appliance or meter 
• Pilot lights that won’t stay lit 
• Bubbling water or dirt outdoors where a line runs 
• Dead vegetation along a buried path 
• Physical symptoms — headache, nausea, dizziness 

What to do: 

1. Turn off the gas at the main shutoff (if safe). 
2. Get everyone outside. 
3. Call 911 or your gas utility.
4. Once cleared, call us — we’ll find and fix it safely.

What Causes Gas Line Problems

Gas systems fail for a handful of reasons — and most have nothing to do with luck:

• Age & corrosion: where black iron meets moisture or soil.
• Vibration: attic fans, HVAC units, and even footsteps can stress lines.
• Rodent damage: chewed CSST or flex connectors.
• Improper support: pipes that move every time a furnace cycles.
• Soil movement: clay expansion cracks slabs and shears buried lines.
• DIY work: mismatched materials, Teflon on flare fittings, or unthreaded joints. Gas doesn’t forgive shortcuts. Every connection has to seal right the first time.

Our Process — Safety First, Always

Every gas job starts and ends with one goal: safety. 

Step 1 — Isolation 

We shut the system down and confirm it’s depressurized before we touch a wrench.

Step 2 — Testing 

We pressure-test the line with air or nitrogen — never gas.  

This finds even the smallest leaks before the line goes back into service.

Step 3 — Locate & Repair 

We use detection equipment to pinpoint the issue — not just chase smells.  That could mean tightening a joint, replacing a section, or rerunning the entire line.

Step 4 — Inspection & Re-Test 

After repair, we retest to code standards.  

If it’s a permitted job, we handle the inspection and paperwork from start to finish.

Step 5 — Safety Verification 

We relight pilots, check combustion air, and verify proper venting.  When we leave, the system isn’t just running — it’s right.

Real Testing — Not the YouTube Version

Most cities around North Texas only require a 2.5 psi pressure test, but we usually go a little  higher — 3.5 psi from the meter in, all the way through the line.  

That’s the only way to prove it’s tight. 

We always test from the meter to the last appliance, because that’s the real system.  On older homes, this can feel like opening a can of worms — and here’s why. 

Those old thread sealants have been sitting for a decade or more, only holding back 4–6 ounces  of pressure.  

When we bring that system up to 3.5 psi to verify it’s safe, some of those joints can give out. 

It’s not us “causing” a leak — it’s the first time that line’s been under real stress since the day it  was built. 

And when homeowners say, “But I never smelled gas before!” 

That’s because at ounces of pressure, a weak joint can hold.  

At pounds of pressure, it tells the truth.  

That’s why we warn every customer — expect a few issues during testing.

Bubble Watching — The Old-School Truth

You can talk all day about electronic sniffers and fancy sensors, but nine times out of ten, it still  comes down to a spray bottle and a pair of tired eyes. 

We hit every joint with soapy water and stare — sometimes for minutes.  If a bubble forms, even slow, it’s a leak. 

No alarms, no gimmicks. Just patience and experience.  

It’s how plumbers have been proving gas joints for over a century.  

And yeah — after a while, your eyes start to cross, but that’s what it takes to keep people safe.

Where the Leaks Hide

In North Texas slab homes, gas lines almost always run through the attic — and that means  chasing leaks in the middle of August feels like working inside an oven lined with fiberglass. 

In pier-and-beam homes, the story flips — the lines run under the floor, and that means  crawling through tight, dusty spaces with critters and damp soil. 

Either way, we go where the line goes.  

Hot attic, cold crawl, doesn’t matter — we find it, prove it, and make it right.

The Last Resort — Walls and Brick

The very last spots we check are the ones that mean opening sheetrock or brick.  We’ll check and double-check every fitting, every run, and every joint before we cut anything  open. 

If we’re opening a wall, it’s because we’ve proven that’s exactly where the problem is — not a  guess, not a gamble.  

That’s what separates a real plumber from a parts changer.

The CSST Story

Then there’s CSST (Corrugated Stainless Steel Tubing) — the flexible yellow gas line you see  in newer builds.  

We bring 2 psi of gas into the home, reduce it in the attic through a central manifold, and vent  the regulator through the eave per code. 

It works, but it’s not my favorite design.  

That much pressure overhead, with flexible tubing and lightweight strapping, can lead to long term issues — especially when the bonding isn’t done right. 

CSST is fast to install, but like everything else in plumbing, speed isn’t the same as quality.
