Smell Gas in Your Home? What Massachusetts Homeowners Should Do Right Now

As the weather cools down, gas appliances across Newton, Brookline and Boston start working harder. Boilers kick on, gas fireplaces get their first use of the season, and the stove gets a workout for fall cooking. It’s also the time of year when we hear from homeowners who notice a faint “rotten egg” smell and aren’t sure whether it’s serious.

Here’s the short answer: any gas smell should be taken seriously. Natural gas has no smell of its own. Utility companies add a sulfur-like odorant specifically so you’ll notice a leak. If you smell it, that warning is doing its job.

This guide covers what to do the moment you smell gas, what not to do, and what happens after the utility makes your home safe.

If You Smell Gas: Do These Things Immediately

  1. Get everyone out of the house, including pets. Don’t stop to search for the source of the leak.
  2. Leave doors open behind you if it’s quick and easy to do so on your way out.
  3. Once you’re outside and a safe distance away, call 911 or your gas utility’s emergency line. In most of Greater Boston, that’s National Grid or Eversource. The number is on your gas bill, and it’s worth saving in your phone today.
  4. Stay outside until emergency responders or the utility tell you it’s safe to go back in.
Good to know: Gas utilities respond to odor calls as emergencies. Don’t worry about “bothering” them over something that might turn out to be nothing.

What NOT to Do When You Smell Gas

A gas leak can ignite from even a tiny spark. While you’re inside, do not:

  • Turn light switches, lamps or appliances on or off
  • Use your phone, a flashlight, or a doorbell
  • Light a match, lighter or candle
  • Start a car in an attached garage
  • Unplug anything from the wall
  • Try to find or fix the leak yourself
Why it matters: Flipping a light switch or unplugging an appliance can create a small spark, which is all it takes to ignite gas that has built up indoors.

Other Signs of a Gas Leak

Smell is the most common sign, but not the only one. Watch for:

  • A hissing or whistling sound near a gas line, meter or appliance
  • A gas stove flame that’s yellow or orange instead of crisp blue
  • Dead or browning grass or plants in a strip over an outdoor gas line
  • Bubbles in standing water near where a gas line runs outside
  • Unexplained headaches, dizziness or nausea that improve when you leave the house

That last one can also point to carbon monoxide, which has no smell at all. Make sure you have working CO alarms on every level of your home, as Massachusetts law requires in homes with gas appliances.

After the Utility Leaves: What Happens Next?

When the gas company responds, their job is to make the situation safe. Depending on what they find, they may:

  • Shut off gas to your entire home at the meter
  • Shut off and “red tag” a specific appliance, meaning it can’t be used until it’s repaired
  • Find a leak on their side of the meter, which the utility handles

If the problem is on your side of the meter, such as your gas piping, appliance connections, boiler, water heater, stove or dryer, the repair is your responsibility. That’s where a licensed gas fitter comes in.

At Mr Fix It Plumbing, we locate the leak, make the repair, pressure-test the line to confirm it’s tight, and coordinate with the utility and local inspector as needed so your gas service can be safely restored.

Why Gas Work in Massachusetts Needs a Licensed Gas Fitter

In Massachusetts, gas fitting is regulated by the state, and installing or repairing gas piping and gas appliances must be done by a licensed gas fitter. Most gas work also requires a permit and an inspection by your town or city’s gas inspector.

That applies to more jobs than many homeowners expect, including:

  • Installing a new gas stove or range, including switching from electric to gas
  • Hooking up a gas dryer
  • Installing a gas fireplace or insert
  • Running a new gas line to a grill, kitchen, or addition
  • Replacing a gas water heater or boiler

It can be tempting to hook up a new gas stove yourself, or let the delivery crew do it. But a gas connection done wrong can leak slowly for weeks before anyone notices. A licensed gas fitter makes sure the right connector, shut-off valve and fittings are used, tests for leaks, and pulls the permit so your work is properly inspected. That protects your family, and it can matter to your homeowner’s insurance, too.

Pro Tip: If you’re planning a kitchen remodel that includes a gas range, bring us in early. It’s much easier to plan the gas line before cabinets and flooring go in.

Simple Gas Safety Habits for Fall and Winter

  • Keep the area around your boiler and water heater clear of boxes, laundry and anything flammable.
  • Watch your stove flames. They should be steady and mostly blue.
  • Don’t use your gas oven or stove to heat your home.
  • Keep outdoor vents clear of leaves now and snow later in the season. Blocked vents can push exhaust back into the house.
  • Have your gas appliances inspected if they’re older or haven’t been serviced in years.
  • Know where your gas meter is and save your utility’s emergency number in your phone.
