Certified Gas Line Repair
Licensed, certified, and available for emergency response in Roseland.
⚠️ IF YOU SMELL GAS - LEAVE YOUR HOME IMMEDIATELY. Do not touch switches. Call from outside.
Every gas line repair we perform is documented for permit inspection. We do not cut corners on pressure testing, bonding, or code compliance.
Gas line issues cannot wait. We offer priority scheduling for suspected leaks, failed pressure tests, and appliance stub-out emergencies throughout Roseland.
Our technicians hold the certifications required by FL for gas line work, including CSST bonding and arc-flash grounding compliance.
Every job includes a documented manometer pressure test. This protects you at permit inspection, with your insurer, and at the point of home sale.
Understanding Gas Line Materials
Not all gas lines are the same, and the repair approach changes completely based on what material is in your walls. There are three gas line materials in common residential use, and each requires a different approach when it comes to installation, repair, and inspection.
The traditional material for residential gas lines in the US. Sections are joined with threaded couplings and pipe dope or PTFE tape rated for gas service. Requires proper torque on all connections and correct pipe dope application to prevent seepage. All connections require pressure testing before gas service is restored.
Flexible yellow tubing that replaced much of the black iron in homes built after the early 1990s. Faster to install but requires proper bonding and grounding to prevent arc-flash perforation during lightning events. Most jurisdictions require that CSST be bonded to the electrical grounding system - many older CSST installations are not properly bonded.
Acceptable for propane service in many jurisdictions but not for natural gas (natural gas can contain hydrogen sulfide which reacts with copper). If you have copper gas lines, your system was installed for propane. Converting to natural gas requires full replacement of the copper runs with black iron or CSST.
CSST bonding and grounding is one of the most frequently missed code requirements in residential gas systems. The corrugated stainless steel wall of CSST is thin enough that a lightning-induced voltage surge traveling through the gas line system can arc through the tubing wall, creating a perforation that leaks gas. Bonding the CSST to the home's electrical grounding system equalizes voltage and prevents this arc. The National Fuel Gas Code and most state plumbing codes require CSST bonding, but millions of older installations were made before this requirement was widely enforced - and many DIY additions have never been bonded at all.
The pressure test methodology for gas lines is more stringent than most homeowners expect. A visual inspection of connections with bubble solution (soap and water) catches only large active leaks - it misses micro-leaks and leaks at joints that seal under visual inspection but open under pressure changes. A proper pressure test uses a manometer: the gas line section is pressurized to a test pressure above operating pressure, and the manometer measures whether that pressure holds steady over a prescribed time period. In most residential systems, the test section must hold pressure for a minimum of 10 to 15 minutes with no measurable drop. This is the only test accepted by building inspectors for permit sign-off - bubble solution testing alone does not satisfy the code requirement.
Natural gas line sizing is an aspect of gas work that often goes unexamined until an appliance problem appears. Each appliance on a gas system has a BTU load requirement, and the supply line to that appliance must be sized to deliver adequate gas volume at the required pressure. An undersized line creates a pressure drop during operation that causes the appliance to run inefficiently or fail to maintain temperature - a furnace that short-cycles, a range burner that will not hold a simmer, or a water heater that cannot recover fast enough are all symptoms that get misdiagnosed as appliance failures. When the real cause is gas supply line undersizing, appliance replacement does not solve the problem. A properly sized gas line calculation accounts for the total BTU load of all connected appliances, the pipe length, and the number of fittings in the run.
Propane line sizing adds another variable: propane is a liquid in the tank and a gas at the appliance, and conversion occurs at the regulator. Propane systems operate at a different supply pressure than natural gas, and the line sizing calculations are different. A plumber who works exclusively on natural gas systems may not be familiar with the BTU delivery differences in propane systems. We work on both and understand the distinctions.
What We Do
Every service below is performed by licensed gas line technicians and includes documented pressure testing and permit-ready documentation.
We pressure-test gas line sections using a calibrated manometer at the required test pressure for the prescribed time period. Every test produces a written record of starting pressure, ending pressure, test duration, and pass/fail result - ready for permit inspection.
We inspect existing CSST installations for bonding compliance and install proper bonding conductors and clamps per the applicable code requirements. This is a life-safety repair for any home with unbonded CSST, and it is required for permit sign-off on any CSST-involved work.
We repair and replace black iron gas line sections including threaded couplings, tees, elbows, and unions. All connections are made with gas-rated pipe dope and pressure-tested before service is restored. We also correct improperly supported sections that are creating stress on joints.
We convert propane systems to natural gas service, replacing copper tubing with code-compliant materials, resizing line runs for natural gas BTU delivery requirements, and coordinating with the utility for final pressure and connection at the meter.
We install gas stub-outs for new appliances including ranges, dryers, fireplaces, generators, and outdoor grills. Each stub-out is properly sized for the appliance BTU load, includes a code-required shutoff valve at the connection point, and is pressure-tested before appliance connection.
Seismic shutoff valves (also called excess-flow valves or earthquake shutoffs) automatically cut gas flow during a seismic event or a sudden pressure drop. We inspect, test, replace, and reset seismic shutoff valves - some jurisdictions in FL require them on all new installations and at point of sale.
Our Service Process
For suspected active leaks, call us after you are outside and safe. For non-emergency gas line work, we schedule promptly. We ask about your gas system type to arrive prepared.
We identify your pipe material, inspect all accessible connections and supports, check CSST bonding status, and assess the scope of repair or installation needed before any work begins.
We perform the repair or installation in compliance with the applicable gas code for FL, using the correct materials and techniques for your specific pipe type.
Every job concludes with a documented manometer pressure test. You receive a written report suitable for permit inspection, your records, or your insurance file.
Client Experiences
“Called after smelling gas near my dryer connection. They found a weeping fitting at the stub-out, repaired it the same day, and gave me a signed pressure test report for my records. Could not ask for more.”
“My furnace kept short-cycling and two HVAC companies couldn't diagnose it. Turned out to be an undersized gas line run from a previous addition. They resized it and the furnace has run perfectly since.”
“Added a gas fireplace and they installed the stub-out and shutoff valve with full documentation for the permit. Inspector cleared it first visit. Excellent workmanship and clear communication throughout.”
