Wilmington
The Wilmington angle on gas work
In Wilmington, gas line work often arrives with renovations and appliance upgrades. Converted rowhouses often contain basement-level apartments with minimal flood protection and shared party-wall plumbing. Historic districts hold brick rowhouses and early-1900s twins with aging galvanized and cast-iron plumbing. Older homes may still run on undersized or aging gas piping that a new range or generator will expose.
Around New Castle County, the pattern is familiar: converted rowhouses often contain basement-level apartments with minimal flood protection and shared party-wall plumbing.. High water table: coastal-plain groundwater keeps basements and crawl spaces chronically damp, stressing sump systems. Gas pros here size and route lines for the house as it is, not as the blueprint imagined.

When to call about a gas line
The safety rules come first because they matter most. For non-emergency gas line needs, here is when to call.
- A rotten-egg or sulfur smell near gas appliances or lines.
- A hissing sound near a gas connection or meter.
- Dead vegetation in a line above a buried gas pipe outdoors.
- A gas appliance that will not stay lit or burns with a yellow flame.
- Higher-than-normal gas bills with no change in usage.
What gas line service includes
Expect methodical work with documentation — pressure tests do not lie, and pros who do gas work know it.
- Assessment of the existing gas piping: material, sizing, and condition.
- New gas line runs for appliances, outdoor kitchens, generators, and fire features.
- Repair or replacement of corroded, undersized, or damaged sections.
- Proper sizing calculations so every appliance gets the gas it needs.
- Pressure testing of all work before anything is put into service.
- Coordination on permits and inspections where the locality requires them.
Safety first: what to do
Memorize the smell-of-gas drill before you ever need it. Then handle the non-emergency steps.
Safe to do now
- Know where your gas meter shutoff is and how to turn it with a wrench.
- Keep the area around the gas meter clear and accessible.
- Install a carbon monoxide detector near gas appliances.
- Note the location of buried gas lines before any digging — call 811 first.
Stop — call a pro
- Never attempt gas line work yourself — no fittings, no extensions, no exceptions.
- Do not use open flame to check for leaks.
- Do not ignore a gas smell hoping it dissipates — leave and call for help.
- Do not bury or conceal gas connections where they cannot be inspected.
From plan to pressure test
Gas jobs follow a strict sequence — plan, permit, install, test. Here is the order.
Safety first: if you smell gas, leave the house and call the gas utility or 911 — do not operate switches or phones inside.
Leak detection: the pro isolates sections and pressure-tests to pinpoint the leak.
Repair or new run: damaged sections get replaced; new appliance runs get sized, routed, and permitted.
Test and verify: every joint is pressure-tested and inspected before gas service is restored.
The decision factors
Material, distance, trenching versus interior runs, and permit requirements shape the number. Know them.
- New installation versus leak repair.
- Line length and routing — through walls, attic, or underground.
- Pipe material — black iron, CSST, or copper depending on code and application.
- Permits and inspections required by the city.
- Number of appliances on the run and total BTU load sizing.
