If you smell gas in an Alpharetta home, leave first and call 911 and Atlanta Gas Light at 877.427.4321 from outside; AGL's line runs 24 hours. Repairs and new lines on your side of the meter are plumber work, so call the number on this page to be connected with a local plumber in Alpharetta.
Alpharetta is an established north Fulton suburb and tech hub, and most of its homes are from the 1980s through the 2000s. Census survey data put the median build year at 1996, with under 8% built before 1980. Fulton County's development authority states that Atlanta Gas Light maintains the area's gas infrastructure, so AGL owns the pipes and meters while you buy gas from a marketer.
What to do right now
- Smell gas? Get everyone out. Do not flip switches, use the garage door opener or start a car in an attached garage.
- Call from outside. Dial 911, then Atlanta Gas Light at 877.427.4321.
- Stay out until AGL or the fire department says it is safe. AGL may lock the meter if the leak is on your side.
- Book the repair. A plumber finds and fixes the leak on the house side, pressure tests the piping and pulls the city trade permit.
- Planning new work instead? List the gas appliances you have and the one you want to add, so the plumber can size the line.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Sulfur smell near the water heater or furnace | Leaking connector, valve or union |
| Tankless heater shuts down when the furnace runs | Supply line too small for combined load |
| Yellow, lazy burner flames | Air mixture or dirty burner, not always a leak |
| Gas fireplace slow to light | Weak supply, bad thermocouple or valve |
| Bill rising with no change in use | Slow leak somewhere in the piping |
What affects cost
- Distance from the meter or manifold to the appliance
- Upsizing the main line for a tankless heater or big range
- Finished basement ceilings that limit access
- Outdoor lines to a kitchen, fire pit or generator
- The city trade permit and inspection, applied for through Alpharetta's online portal
Calling for help
The number on this page connects you with an independent plumber who works on gas piping in Alpharetta. Many homes here are now old enough that original furnaces and water heaters are due for replacement, and that is the natural moment to check pipe sizing, replace old connectors and add shutoffs where they are missing. If you are finishing a basement, have exposed gas lines checked before the ceiling closes in.
