When PG&E can't use your existing service conduit, we trench and set a new one from their splice point to your meter main. PG&E pulls the new cable.
Underground service has no mast and no weatherhead — there is nothing overhead to corrode, lean, or get taken out by a falling limb. What you have instead is a conduit in the ground, usually running from a PG&E splice box near the street or a riser on a nearby pole to the combination meter main on the side of your house, with PG&E's service cable inside it. This page is about that conduit and the trench it lives in, and what happens when PG&E can't use the one you have.
Conduit fails quietly, which is why it usually gets found during other work. Roots and driveway settling crush or offset it. Water sits in a run that was never properly sealed and shows up as rust inside the meter enclosure. A panel relocation moves where the run has to land. Some services have no approved conduit at all: the cable is buried directly in the ground or came as cable-in-conduit, and PG&E requires new cable in approved conduit when that panel is upgraded past 125 amps. And the one to plan for: the existing conduit is too small for the larger cable an upsize needs, which turns a cable pull into a trench.
Who owns what. Under PG&E's Electric Rule 16, PG&E furnishes, installs and owns the underground service cable, from its distribution line to the connection in your meter main. We don't pull that cable or land it. The trench, the backfill and the conduit on your property are the homeowner's side, and that is the part we build. Before PG&E pulls larger cable through an existing conduit, the conduit has to be proved clear and big enough to take it. Whether it can be reused or a new one gets trenched is the single biggest cost variable on the job. Plan and budget for the trench. An existing conduit can be reused only if it is at least 2 inches (PG&E's minimum for an upgrade to 200 amps; larger services need more) and in usable condition. PG&E confirms that after a signed contract, because signing is what lets us file the application, and when it can be reused, you save the cost of the trench. If it is smaller or not usable, the trench goes ahead and the job continues.
As with overhead service, if the panel is being replaced then this is not a separate purchase. A main panel job in our area is a full service rebuild, quoted as one scope, with the trench included when it needs one, and the 200A panel upgrade page covers it. This page is the other case: the panel is sound and staying, and the conduit feeding it is what needs replacing. Same amperage or an upsize, the paragraph above applies: plan for the trench.
A tech checks the meter main, measures the visible conduit, and walks the likely trench route with you. The sealed compartment where PG&E's cable lands stays closed unless PG&E is on site. You get a written report and a quote planned around the full trenched job.
We pull the building permit and file the service application with PG&E. This is the step where PG&E verifies whether your existing conduit can take its cable and approves the design for a new one — which happens after contract rather than before, because the application is what triggers their review.
We open the route and set the conduit and sweeps. PG&E's inspector has to see the conduit in the open trench before it is covered. Then we backfill, compact, and prove the conduit clear with a mandrel with the inspector on site.
Once the building department has signed off, PG&E pulls its new cable through the conduit, connects it in your meter main, and restores power. We walk the finished work with you, hand over the permit number and the inspection sign-off, and register the 20-year warranty.
Plan and budget for the full trenched run. Replacing an underground run means a new conduit from PG&E's splice point to your combination meter main, and whether PG&E can reuse your existing one is not known until after you sign, because PG&E confirms it once a signed contract lets us file the application. So the quote assumes a new conduit in a new trench. An existing conduit can be reused only if it is at least 2 inches and in usable condition, and when it can, the trench drops out and you save its cost. If it is smaller or not usable, the trench goes ahead and the job continues. After that, the number moves on trench length, what sits on top of the route, and how far the splice point is from the panel. PG&E pulls its own cable and may bill for it on an upgrade; that cost comes from PG&E's estimate.

“Thank you to the Sunrise Electrical Contracting team for updating the new main electrical system on my mom's home after the storm damaged the power lines and home equipment this winter… They replaced Main Service Upgrade Overhead, and added a Sub-Panel Install/Replacement Outdoors… the team of Branden, Jimmy, Ian, and Tylor worked long hours during the storm for a few days to get us up and running again before the next storm arrived.”
“I can't begin to describe how much Branden and Sunrise helped us out of a pinch. We had a serious electrical issue in our panel, and his team were on it. Worked quickly with the city and with PG&E to address the issue, and came in thousands of dollars under competitors' quotes. Hands-down, the best electrical company in Santa Cruz County!”
Pulled from what we actually hear on quotes and on-site. If yours isn't here, ask us — we'll answer in plain English.
We'd rather you get the right outcome than the Sunrise outcome. Some of this points away from us on purpose.
Look for a CSLB-licensed C-10 contractor near you and verify the licence at cslb.ca.gov. On underground work specifically, ask how they handle the utility application and what happens to your price if the existing conduit is rejected — a contractor who has not thought about that has not done many of these. Ask for liability and workers-comp proof.
