Gas Line Repair in Dover, NH
About 41% of homes in Dover are on mains gas and 8% on propane. The split matters because a meter is a legal boundary and a propane tank is not.
Read this first
Mains gas heats 41% of homes in Dover and tank gas another 8%. The difference matters more than the fault does at first, because only one of the two has a meter outlet where the utility's responsibility stops.
Source: US Census Bureau, American Community Survey table B25040; the service line boundary is 49 CFR § 192.3.
If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How Dover is supplied
Mains and tank gas differ in ownership, in who to call, and in how the gas behaves if it escapes — propane is heavier than air and collects low rather than rising.
What they do not differ in is the emergency response, which is the same for both and is the first thing on every page of this site.

Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 15,021 occupied housing units. Read it as fuel rather than as plumbing. The share on utility gas is how many houses burn it, which is the nearest thing published to how many have a service line. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across New Hampshire as a whole, 25% of households are on mains gas and 17% on tank propane. Dover sits 15 points above the state on mains and 9 points below it on propane. That is the gap a statewide number papers over, and the reason the figures above are this town’s rather than the state’s.
Before anyone digs on the property
One free call before any excavation. PHMSA is blunt about why: excavation damage is the leading cause of pipeline incidents, and 8-1-1 raises the odds of avoiding one to 99 in 100. It applies to a fence post as much as a foundation.

What to ask whoever quotes it
Ask whether the job needs a permit and who is pulling it. Gas work is separately permitted in most jurisdictions and the answer should not be you.

Checking a plumber in New Hampshire
The authority is the New Hampshire Office of Professional Licensure and Certification, Mechanical Safety and Licensing Board. New Hampshire licenses plumbers but publishes no online licensee search, so verification means contacting the office directly.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. Other Dover requests are covered by the same line.
