Gas Line Installation & Repair services
Gas line installation and repair cover approved residential fuel-gas piping changes, connections, and correction of identified piping defects. Work begins only after the area is safe and the route, load, pipe material, pressure, shutoffs, appliances, access, and project requirements are evaluated.
Gas leak inspection and repair
If a gas leak is suspected, leave the area and contact the gas utility or emergency services first; after the site is declared safe, we can locate and repair eligible customer-owned piping.
Gas line installation
When an approved appliance or new connection needs gas service, we can install eligible piping after reviewing the route, connected load, and existing system capacity.
Gas line replacement or rerouting
If a gas line is damaged, unsuitable, or inaccessible for a practical repair, we can replace or reroute the approved section.
Gas shutoff valve service
When an eligible customer-owned shutoff valve is leaking, damaged, or difficult to operate, we can repair or replace it within the approved scope.
Pressure testing and restoration checks
After approved gas piping work is completed, we test the system and follow the applicable inspection or utility steps before service is restored.
Our same day service promise
Our fully stocked trucks help us complete eligible, approved work during the same visit. Specialty parts, permits, or added work may require a follow-up.
100% Satisfaction Guarantee
If you are not satisfied with our completed work, we will return and redo work within the approved scope at no additional charge.
Signs you may need gas line installation & repair
If gas is suspected, evacuate immediately and call SoCalGas at 1-800-427-2200 from a safe location; call 911 when the leak may endanger people or property.
You smell gas or hear hissing
Leave the area immediately and call the gas utility from a safe location. Do not operate switches, appliances, vehicles, flames, or devices that could create a spark, and do not attempt a repair.
A gas appliance is being added or relocated
The appliance input, existing piping capacity, route, shutoff, venting or combustion requirements, and utility conditions must be evaluated.
A connection or pipe has been damaged
Do not test it yourself. Even apparently small damage should be reported and the system made safe before repair planning.
What determines gas-line scope?
Connected load and pressure
Existing and proposed appliances, pipe length, sizing, and supply conditions shape the design.
Route, material, and access
Approved materials, supports, protection, shutoffs, transitions, and accessible routing affect installation.
Testing and restoration
The completed approved scope requires appropriate testing before service is restored; only the utility restores service at its meter when utility shutdown applies.
Emergency utility response, repair, or installation?
Suspected active leak
Evacuate and contact the gas utility from a safe location before plumbing work is considered.
Repair
For an identified defect after the area and supply are controlled.
Installation
For a planned appliance, branch, relocation, or replacement project with a defined load and route.
