Fireplace Gas Line Installation & Repair
Whether you’re adding a gas fireplace, gas log set, or gas starter to a room that’s never had one, or fixing a leak or failed valve on an existing line, gas work at the fireplace isn’t a DIY job. We run, connect, and repair gas lines for fireplaces across DFW — installed to code, pressure-tested, and signed off before we leave.
The Chimney Sweep has installed and repaired fireplace gas lines across Dallas–Fort Worth since 1980, working on everything from new gas log installs to line repairs on existing gas fireplaces.
What Fireplace Gas Line Work Involves
A fireplace gas line runs from your home’s gas supply to the appliance — a gas fireplace insert, a gas log set, a gas starter, or an outdoor fire feature — and includes the shutoff valve, fittings, and any regulator the appliance needs. New installs mean running a line where none exists, sizing it correctly for the appliance’s BTU demand, and connecting it to code.
Repairs cover everything from a slow leak at a fitting to a failed shutoff valve or a line that needs to be relocated during a remodel. Because gas work carries real safety stakes — leaks, carbon monoxide risk, fire hazard — every job is pressure-tested before we consider it done.
Why Dallas–Fort Worth Homeowners Call Us for Gas Line Work
Get gas to a fireplace that's never had it
We run new lines for gas inserts, log sets, and gas starters, sized correctly for the appliance.
Fix leaks before they become dangerous
A gas smell near the fireplace is never something to wait on — we find and repair the leak, then pressure-test the line.
Replace worn shutoff valves and fittings
Old or corroded valves are one of the more common points of failure on an aging gas fireplace line.
Every job installed and tested to code
From line sizing to shutoff placement, gas work is inspected and documented, not just eyeballed.

Handled by licensed technicians, from initial diagnosis to final pressure test.
Gas System Evaluation

Line Sizing & Routing
For new installs, we size the line for your appliance's BTU rating and route it to meet code.
Connection & Fittings
We connect the appliance using properly rated fittings, shutoff valves, and regulators.
Leak & Pressure Test

Signs Your Fireplace Gas Line Needs Attention
- You smell gas near the fireplace, even faintly
- The fireplace or gas logs won't light or stay lit
- The shutoff valve is stiff, corroded, or won't fully close
- You're adding a gas fireplace, insert, or log set for the first time
- You're remodeling and need the line relocated
A gas smell in particular is never a wait-and-see situation — shut off the gas at the valve if you can safely reach it, and call us right away.
Gas Line Safety Notes
- Never attempt to repair or extend a gas line yourself
- Keep a working carbon monoxide detector near any gas appliance
- Have gas fireplace lines inspected as part of your annual chimney inspection
- Know the location of your main gas shutoff valve
- If you smell gas, leave the area and call from outside before calling us
