A gas leak is the most dangerous emergency a homeowner can face. It poses immediate risks of fire, explosion, and serious health hazards. At Principle Plumbing, we provide emergency gas leak detection and repair services using advanced equipment and proven safety protocols to protect your home and family.
Whether the leak is behind a wall, underground, or at a specific appliance valve, we isolate the section and repair or replace the damaged piping using code-compliant materials such as Black Iron or CSST (Corrugated Stainless Steel Tubing). Before we leave, we perform a rigorous pressure test by attaching a pressure gauge (manometer) to your system and pumping it with air to a pressure higher than normal operating levels. The gauge must hold steady, proving the system is 100% tight and safe for use.

We don't rely on guesswork or just your nose. Our digital combustible gas leak detectors (sniffers) can detect leaks at parts-per-million levels that humans cannot smell. We use professional-grade manometers for pressure testing and non-corrosive leak detection fluid (bubble test) to pinpoint the exact fitting or pipe thread that has failed.
Gas emergencies are life-threatening. We prioritize gas leak calls and respond quickly when you need us most. Our licensed, bonded, and insured professionals understand the urgency and treat every gas leak with the seriousness it deserves, working safely and efficiently to restore your gas service.
When the gas company red-tags your meter, we perform the necessary repairs using code-compliant materials (Black Iron or CSST). Before we leave, we conduct rigorous pressure testing that exceeds code requirements, proving your system is 100% tight and safe for the utility company to restore service.
We handle all permitting and inspection requirements for the City and coordinate with your utility provider (Nicor/Peoples Gas) to get your meter unlocked. We know exactly what inspectors look for and get your pressure test approved on the first try, minimizing your downtime without gas service.
