What to Do If You Smell Gas: The Steps, in Order

Why you can smell it at all

Natural gas is odorless; the rotten-egg smell is mercaptan, an additive put there specifically so a leak announces itself to a human nose at concentrations far below danger. That means the smell is the detection system working, not necessarily a catastrophe in progress — but it is also not information to sit with. A faint whiff near the stove after a burner mishap is one thing; a persistent or strong smell is your cue to run the checklist below, top to bottom, without improvising.

If the smell is strong: leave first, everything else second

A strong gas smell means get everyone out now, and on the way, touch nothing electrical — no light switches on or off, no phone calls until outside, no garage door opener, nothing that can spark. Leave the door open behind you. From a neighbor's house or the street, call 911 and your gas utility's emergency line. Do not go back in for pets, wallets, or one more check. The professionals have meters and the authority to make the house safe; your only job is to not be inside.

If the smell is faint and clearly local

A faint, localized smell — say, right at the stove after a pot boiled over the flame — is usually a burner or pilot issue. Confirm burners are fully off, ventilate with a window, and see whether the smell clears completely. If it does not clear quickly, or you cannot find an obvious innocent cause, treat it as the strong-smell case: get out and make the calls from outside. When in doubt, escalate — nobody in this trade has ever criticized a homeowner for taking a gas smell too seriously.

After the utility makes it safe, the repair begins

The utility's emergency crew will find the leak, shut off what needs shutting, and often red-tag the failed appliance or line — making things safe, not fixed. Getting gas service properly restored is licensed repair work: replacing the failed section, re-testing the system under pressure, and getting the appliance back online correctly. That is where we come in. Hanna repairs gas lines across Marion, Cedar Rapids, and the Corridor, licensed and insured, with 24/7 availability because leaks do not schedule themselves.

Preventing the next one

Most residential gas problems trace to aging fittings, corroded pipe, appliance connectors past their prime, or amateur work from a previous owner. If your house is older and its gas piping has never been looked at, a pressure test and visual inspection is cheap reassurance. Carbon monoxide alarms belong on every level of a gas-served home regardless — CO is the leak your nose cannot catch. Ask us to look the system over any time we are already there; hourly techs with no quotas means an inspection is an inspection, not a lead-generation exercise.
