Smell gas? Leave the house first. National Grid, the gas utility on Long Island, says to go outside and call 1-800-490-0045 or 911, and not to touch light switches, phones or anything that could make a spark. Call us after National Grid says it's safe.
What we do
- Gas piping from the meter to ranges, dryers, water heaters and other gas appliances
- New gas piping for oil-to-gas conversions
- Gas lines for new or moved appliances during kitchen and laundry remodels
- Repair of leaking or damaged gas piping on your side of the meter, once the utility has made it safe
What we don't do
- The gas service and meter outside the house, which belong to National Grid. National Grid lists a separate line for new service, gas pipe installations and natural gas conversions: 1-877-696-4743.
- Oil delivery or selling oil, and oil boiler repair
- Vent cleaning or duct cleaning
How it works
- Size the piping. Every appliance needs a pipe big enough for its gas demand at the same time as the others. Adding a gas dryer or water heater to an old line can starve the rest.
- Run and support it properly, with a shutoff at each appliance.
- Pressure-test it before anything is connected and lit.
Oil to gas on Long Island
A lot of our area still heats with oil, and every switch to gas needs new piping. The Census Bureau's latest five-year survey shows 73% of Levittown homes heating with fuel oil, 53% in East Meadow, 45% in West Babylon and 40% in Hicksville, against 14% in the Village of Hempstead. When a house switches, the gas line to the new heating equipment is usually only part of the job: if the old boiler made the hot water, the house needs a water heater and a gas line to it too, and many people add a gas range or dryer at the same time.
