Licensed Gas Line Professionals
Safe, reliable gas line services with all permits & inspections: (630) 346-1389
Gas line work requires precision, expertise, and strict adherence to safety codes. At Principle Plumbing, our licensed professionals have the experience and specialized tools to handle all your gas line needs safely and efficiently, from new installations to emergency repairs.
Every installation and repair concludes with a rigorous pressure test. We attach a precision gauge (manometer) to your system and pressurize it with air to levels exceeding normal operating pressure. The gauge must remain perfectly steady, proving your system is 100% sealed and safe. We also coordinate all permits and inspections with local authorities to ensure full compliance.

Whether you're adding a gas fireplace, upgrading to a gas range, or extending service to a detached garage, we design and install gas piping systems that meet all code requirements. We properly size pipes for BTU load, install required shutoff valves, and coordinate with your utility company for meter and service line installation.
We work with both traditional black iron pipe and modern CSST (Corrugated Stainless Steel Tubing) depending on your application. Black iron is ideal for exposed runs and high-capacity needs. CSST offers flexibility for concealed installations and easier routing through walls. We recommend the best material for your specific project.
From leaking fittings and corroded pipes to damaged lines from renovation work, we repair all types of gas line failures. We locate the problem, isolate the damaged section, replace or repair using code-compliant methods, and pressure test the entire system to ensure it's completely sealed before restoring your gas service.
All gas line work requires permits and inspections for your safety and legal compliance. We pull all necessary permits, ensure work meets current code, and coordinate inspections with the city. We know exactly what inspectors require and get your system approved on the first try, avoiding costly callbacks and delays.
