Who We
Work With
We regularly complete gas line trench and installation work for:
- General contractors on new construction and renovation projects
- Plumbing contractors needing dedicated excavation and trench support
- Property developers on residential and commercial builds
- Municipalities and public works departments upgrading gas infrastructure
- Homeowners replacing deteriorated or undersized gas service lines
Gas line work requires precise excavation, careful coordination with SoCalGas, and strict adherence to safety protocols at every phase. Our crews are trained and experienced handling all of it — from the initial dig through final pressure testing and site restoration.
Safety First on Every Gas Line Project
Gas line trenching carries a higher level of responsibility than most underground utility work. A mistake during excavation near an existing gas line or during installation can have serious consequences for the crew, the property, and the surrounding neighborhood.
We treat every gas line project with the level of care it demands. Before any excavation begins we coordinate with 811 and perform vacuum potholing at all key locations to physically verify the position of existing gas lines and surrounding utilities. We use ground-penetrating radar on complex sites and follow strict OSHA and SoCalGas safety protocols throughout every phase of the project.
Our crews are trained specifically on gas line excavation safety and work alongside your plumbing contractor and SoCalGas inspectors to ensure every installation is completed correctly, inspected thoroughly, and restored to full site condition before we leave.
Our Gas Line Process
Site Assessment
We begin with a full site review covering soil conditions, existing utility locations, required trench depth, gas line routing, and access constraints. We identify potential conflicts early and build a clear excavation plan before any equipment hits the ground.
Utility Marking and Potholing
Before any excavation begins we coordinate with 811 and perform vacuum potholing at all key locations to verify the exact position of existing gas lines and surrounding underground utilities. On gas line projects this step is non-negotiable and we never skip it.
Precision Excavation
Our operators trench to exact depth and width specifications — clean sidewalls, consistent bedding, and proper grade throughout. We work carefully and efficiently on open sites and confined urban job sites alike, with equipment matched to each location's conditions.
Gas Line Installation
Our licensed crews install gas pipe, fittings, and all related underground components to project specifications and all applicable SoCalGas, LA County, and California code requirements. We coordinate directly with your plumbing contractor and SoCalGas throughout installation to ensure proper routing, connections, and inspection sign-off.
Backfill and Restoration
Once installation passes pressure testing and receives inspection approval we backfill, compact to required density, and fully restore the surface — including asphalt and concrete repairs where required.

Frequently Asked Questions — Electrical Conduit Trenching in Los Angeles
How deep does a gas line need to be buried in California?
In California residential gas service lines are typically required to be buried a minimum of 18 inches deep. Commercial gas lines and higher pressure mains may require greater depth depending on location, pressure rating, and local requirements. We trench to whatever depth your project specifications and SoCalGas requirements dictate.
Do you handle both the trenching and the gas line installation?
Yes. We provide complete underground gas line services including trench excavation, pipe installation, fitting and regulator coordination, pressure testing coordination with SoCalGas, and full site restoration — all under one contract.
Do you coordinate with SoCalGas on gas line projects in Los Angeles?
Yes. We coordinate directly with SoCalGas throughout the installation and inspection process on all gas line projects in Los Angeles County, ensuring full compliance with their requirements and a smooth path to final inspection approval.
Do you replace existing gas lines or only install new ones?
Both. We handle new gas service line and main installations as well as full replacements of deteriorated, undersized, or damaged gas lines throughout Los Angeles County.
How long does gas line trenching and installation take?
A typical residential gas service line replacement or upgrade can be completed in one to two days. Larger commercial or municipal gas main projects are scoped individually based on length, depth, routing, and site conditions.
