Electrical Panel Upgrade for Hilo homes and businesses

We handle electrical panel upgrade across Hilo and the wider Hawaii Island area. 100 to 200 amp service upgrades, breaker box replacement and sub panels sized for what you actually run. You get a written scope and a fixed number before anyone starts work.

If you are buying or selling in Hilo, an electrical inspection before the offer closes is far cheaper than a renegotiation after it. We document what we find and give you a written scope you can hand to anyone.

Hawaii Island spreads power across long rural feeders, vog-exposed coastline and homes above 2,000 feet that were often owner-built. Corroded lugs and undersized services are the two things we find most.

Call (888) 633-7804 or request a call back and we will book a window that works.

What Hilo customers say

★★★★★

Level 2 charger in a detached carport, about eighty feet from the panel. Quoted the run honestly up front.

They found aluminium branch wiring during an inspection before we bought. Saved us from a very expensive surprise.

Electrical Panel Upgrade in Hilo: frequently asked questions

How do I know my Hilo panel needs upgrading?
Full breaker slots, double-tapped breakers, a fuse box, frequent tripping, a warm cover, scorch marks, or a plan to add an EV charger, AC or a range. Any one of those is a reason to look.
How long does a panel upgrade take in Hilo?
Most residential upgrades are a one day job, with power off for part of it. Utility coordination and inspection can add scheduling time, and we handle that for you.
What size service should I get in Hilo?
200 amp is standard for most homes now, especially with an EV or a heat pump in the plan. We run a load calculation rather than guessing.
Can you replace just the breaker box in Hilo?
Sometimes, if the service and meter are in good condition. If the service entrance cable is undersized or corroded, replacing only the box leaves the real bottleneck in place.
Do I need a permit for a panel upgrade in Hilo?
Service work is permitted and inspected. We take care of the paperwork and the inspection appointment as part of the job.
Will my power be off all day in Hilo?
Not usually all day. We plan the outage window with you in advance so you can move anything temperature sensitive first.
Do you charge extra for nights, weekends or holidays in Hilo?
After-hours work in Hilo is quoted at a flat price before we start, so you know the number before anyone drives out. There is no meter running while we diagnose.
What areas around Hilo do you serve?
We cover Hilo and the wider Hawaii Island area, plus the rest of Hawaii. If you are just outside Hilo, call (888) 633-7804 and we will confirm coverage in one minute.
