Why Call a Licensed Plumber for Gas Lines
Gas lines require precise installation and regular maintenance to ensure safety and compliance with code. Here are key reasons to hire a licensed plumber:
- Correct sizing, bonding, supports, and clearances: Properly sized lines with secure supports and correct clearances prevent leaks and ensure your system meets code requirements.
- Safe, documented pressure tests: Professional plumbers perform thorough pressure tests and provide documentation that passes inspections.
- Proper materials and connections: Using approved materials and expert connections reduces the risk of future leaks or hazards.
- Clean, labeled installations: Clearly labeled and well-organized gas lines make future maintenance easier and safer.
Ignoring gas line issues can lead to leaks, inefficient appliances, or dangerous situations, so professional installation and inspection are essential for your home’s safety.
Understanding the Cost
Pricing is transparent and itemized before work begins. The final cost depends on a number of factors such as:
- Length of run, pipe size, material, and access
- Number of appliances, valves, and regulators
- Localized repair vs. full replacement or reroute
- Permit, testing, and inspection requirements
You receive a written, line-item estimate on site with no surprise fees, and options to match your budget and timeline.

Do I Need to Repair or Replace My Gas Line?
Gas lines are mostly hidden underground, which makes it hard to know when a problem exists. Recognizing warning signs early is crucial for safety.
- Repair – Needed for localized problems: hissing sounds from pipes, visible cracks on exposed sections, unusually high gas bills, dying plants near lines, or poorly performing gas appliances. Addressing these issues promptly can prevent leaks and further damage.
- Replacement – Recommended for more serious or widespread issues: old pipes nearing 20–30 years, rust or corrosion, visible kinks or severe damage, lines that fail to meet current plumbing codes, or when installing new appliances during remodeling. Replacing compromised lines ensures long-term safety and reliable gas delivery.
By monitoring these warning signs and contacting a licensed plumber promptly, you can avoid leaks, property damage, and potential hazards in your home.

FAQs
1) Should I call the gas company or a plumber first?
If you suspect an active leak, evacuate and call 911 or your gas utility from outside. After the area is safe, call us for leaking gas line repair and testing.
2) How do you confirm the leak is fixed?
We isolate the line, repair or replace components, then perform pressure and soap tests. You receive documentation for inspections and utility relight.
3) Can you move or add a gas appliance?
Yes. We size the line for total BTU load, add shutoffs and regulators, and connect the appliance to code as part of our gas line installation service.
4) How long does a typical gas line repair take?
Small repairs can be same day. Larger reroutes or replacements depend on access, permits, and inspection timing.
5) Do you work on both CSST and black iron?
Yes. We repair and install both, including proper bonding for CSST and correct supports for black iron.
