What Causes Gas Leak Smell in House
Natural gas is odorless — the rotten egg/sulfur smell is mercaptan, an additive for leak detection. Gas leaks occur at pipe connections, appliance fittings, gas valve seals, corroded gas pipes, or damaged flexible gas lines. Even small leaks are dangerous due to explosion and asphyxiation risk.
Boise-specific factor: Intermountain Gas Company serves most Boise natural gas customers. Many Boise homes have gas water heaters, furnaces, ranges, and dryers — multiple potential leak points. Older homes with black iron gas pipes may have corroding threaded connections. Earthquake risk in Idaho (Boise is in Seismic Zone 2) adds stress to gas line fittings.
Signs You Have Gas Leak Smell in House
Watch for these warning signs in your home:
- ✓ Rotten egg or sulfur smell near gas appliances or in the house
- ✓ Hissing sound near a gas line or appliance
- ✓ Dead vegetation in a line over buried gas pipes
- ✓ Higher than normal gas bills
- ✓ Pilot lights that keep going out
Can You Fix This Yourself?
If you smell gas strongly: leave the house immediately. Do not flip light switches, use phones, or create any spark. Once outside, call 911 and Intermountain Gas (800-548-3679). Do not re-enter until cleared by the gas company. For faint, intermittent smells near an appliance, ventilate the area and call a plumber.
If the problem persists or you're unsure, call a licensed plumber. Attempting complex repairs without proper tools can cause further damage and void warranties.
