Smell Gas? Here's What to Do.

If you smell a sulfur or rotten egg odor, hear hissing near a gas line or appliance, or suspect any kind of gas leak:

  • 1. Leave your home immediately. Do not turn on or off any lights, switches, or appliances.
  • 2. Call Xcel Energy at 1-800-895-2999 from a safe location.
  • 3. Then call us at (720) 767-0319 for licensed gas line repair. We offer same-day emergency service.

Your safety comes first. Once Xcel confirms the area is safe, our licensed plumbers will locate the leak, make the repair, pressure test the line, and coordinate any required inspections—so your gas is restored safely and properly.

Gas Line Repair in Denver

When a gas line fails, you need a licensed professional who can respond quickly, diagnose the issue accurately, and complete the repair to code. At Mr. Perfect Plumbing, every gas line repair is performed or directly supervised by a Colorado-licensed Master Plumber with over 20 years of hands-on experience. We don’t send general handymen or unlicensed techs—we send professionals who specialize in this work.

Gas leaks and gas line damage can happen for a number of reasons: aging pipe materials, ground shifting from Colorado’s clay soil, frost heave, corrosion, or improper work by a previous contractor. Whatever the cause, we locate the problem, explain what needs to happen, and provide a clear written estimate before any work begins.

Signs You May Need Gas Line Repair

  • A sulfur or rotten ehh smell inside or outside your home
  • Hissing, whistling, or roaring sounds near gas lines, the meter, or appliances
  • Dead or dying vegetation along the path of an underground gas line
  • An unexplained increase in your gas bill
  • Pilot light that won't stay lit or appliances that aren't firing properly
  • Visible corrosion, rust, or damage on exposed gas piping

If you notice any of these signs, don’t wait. Gas line issues can escalate quickly. Call (720) 743-5178 and we’ll get a licensed plumber to your home as soon as possible.

Gas Pressure Testing in Denver

A gas pressure test verifies that your home’s gas piping system is sealed, leak-free, and safe to operate. It’s a standard requirement in several common situations, and in most cases, it must be performed by a licensed plumber with the proper permits before your gas utility will restore or connect service.

When Is a Gas Pressure Test Required?

  • Xcel Energy service reconnection: If your gas was shut off—whether for nonpayment, a safety concern, or an extended vacancy—Xcel typically requires a licensed gas pressure test and city inspection before restoring service.
  • Real estate transactions: Buyers, sellers, or lenders may require a gas pressure test as part of a home inspection or closing condition.
  • New construction or remodeling: Any new gas piping or modifications to existing gas lines require testing and inspection before use.

How the Process Works

We handle the entire process from start to finish so you don’t have to coordinate between multiple parties:

  • We pull the required permit under our Colorado plumbing license with your local jurisdiction.
  • We pressurize the system using air or nitrogen and monitor the gauge for a minimum of 30 minutes at the required pressure (typically 10 PSI or higher, depending on the system) per Colorado fuel gas code.
  • We inspect all visible gas connections and appliance hookups for code compliance, checking fittings, valves, and connectors.
  • If leaks or code issues are found, we make the repairs on the spot and retest until the system holds.
  • We schedule the city inspection and coordinate with the inspector. Once the inspection passes, your gas utility can restore service.

You don't need to worry about the paperwork, the permits, or the back-and-forth with the city. We handle it all.

Gas Line Inspection in Denver

A gas line inspection is a thorough evaluation of your home’s gas piping, connections, and appliance hookups to identify safety concerns, code violations, or early signs of wear. Unlike a pressure test (which checks for leaks under pressure), an inspection looks at the overall condition of your gas system—materials, routing, support, ventilation, and compliance with current code.

When Should You Get a Gas Inspection?

  • Buying or selling a home:

    A gas inspection can identify hidden safety issues that a general home inspection might miss.

  • Older has systems:

    If your home is 20+ years old and the gas piping has never been evaluated, an inspection can catch aging connectors, outdated materials, or improperly routed lines.

  • After ground movement or settling:

    Denver’s expansive clay soil causes foundation shifting that can stress underground and interior gas piping.

  • Unexplained performance issues:

    Appliances that aren’t heating efficiently, pilot lights that struggle, or inconsistent hot water can sometimes trace back to gas delivery problems.

  • Peace of mind:

    If you’ve never had your gas lines professionally evaluated, a routine inspection is a smart preventive step.

Our inspection includes a visual evaluation of all accessible gas piping, connections, shutoff valves, appliance hookups, and venting. We’ll document what we find, explain any concerns, and provide recommendations—with no pressure to commit to anything on the spot.

Gas Line Installation for Appliance & Outdoor Features

Whether you’re adding a gas stove, converting from electric to gas, running a line to an outdoor grill or fire pit, or connecting a new water heater or furnace, gas line installation requires proper sizing, code-compliant materials, pressure testing, and coordination with local inspectors.

We evaluate your existing gas system to ensure it can support the additional load, size the new line correctly, and handle all permit coordination and inspections. Every installation is pressure tested and inspected before we consider the job complete.

Common Gas Line Installation Projects

  • Gas stove and range hookups
  • Gas dryer connections
  • Outdoor BBQ grills and gas fire pits
  • Gas fireplace installation and hookup
  • Gas water heater and tankless water heater connections
  • Whole-home electric-to-gas conversions
  • Gas line upgrades for higher-capacity appliances

Gas Line Service FAQs

  • Q: Can any plumber work on gas lines?

    No. Gas line work in Colorado requires specific licensing and training. Always verify that your plumber holds a valid Colorado plumbing license that authorizes gas work. At Mr. Perfect Plumbing, all gas line work is performed or supervised by our licensed Master Plumber.

  • Q: What should I do if I smell gas in my home?

    Leave your home immediately without turning on or off any switches or appliances. Once you’re safely outside, call Xcel Energy at 1-800-895-2999 to report the leak. After the situation is stabilized, call us at (720) 743-5178 for licensed gas line repair.

  • Q: Does Xcel Energy require a pressure test before turning on gas?

    In most cases, yes. If your gas was disconnected—whether due to nonpayment, a vacancy, safety concerns, or previous work—Xcel typically requires a gas pressure test performed by a licensed plumber, along with a city inspection, before restoring service. We handle the permit, the test, and the inspection coordination for you.

  • Q: How much does a gas pressure test cost in Denver?

    Cost depends on the size of the system, the jurisdiction’s permit fees, and whether any repairs are needed during the test. We provide exact pricing over the phone when you call, and there are never hidden fees. The test itself typically takes a few hours including inspection coordination.

  • Q: How long does a gas line repair take?

    Most residential gas line repairs can be completed in a single visit—often within a few hours. More complex issues, like underground line replacement or whole-system re-piping, may take longer. We’ll give you a clear timeline during your estimate so you know what to expect.

  • Q: Do gas line installations require permits?

    In most Denver-area jurisdictions, yes. New gas line installations, modifications to existing lines, and pressure tests typically require a permit and inspection. We pull all required permits under our license and coordinate the inspection process—you don’t have to deal with any of it.

  • Q: How often should gas lines be inspected?

    There’s no single rule, but we recommend a professional gas line inspection if your home is over 20 years old, if you’re buying or selling a property, or if you’ve noticed any signs of gas line issues. Routine inspections are a smart preventive measure—especially in Denver, where clay soil movement can stress underground piping over time.

  • Q: Can you run a gas line to my outdoor grill or fire pit?

    Absolutely. We install gas lines for outdoor grills, fire pits, outdoor kitchens, and patio heaters. Every outdoor gas line is installed with proper burial depth, code-compliant materials, a dedicated shutoff valve, and a final pressure test. We handle the permit and inspection so you’re ready to fire it up.

  • Q: Do you handle gas line work for water heaters and boilers?

    Yes. Gas line connections are a standard part of our water heater and boiler installation services. If you’re replacing a gas water heater, upgrading to a tankless unit, or servicing a boiler, we ensure the gas supply is properly sized, connected, and tested as part of the job.

  • Q: What areas do you serve for gas line work?

    We provide gas line repair, inspection, pressure testing, and installation throughout the Denver metro area, including Denver, Aurora, Lakewood, Littleton, Centennial, Englewood, Arvada, Westminster, Thornton, and surrounding communities.
