Electrical Panel Upgrade for Koloa homes and businesses

We handle electrical panel upgrade across Koloa and the wider Kauai 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.

Rentals and vacation properties in Koloa need work scheduled around guests. We book early morning, evening and between-stay windows, and we clean up so a unit turns over the same day.

Kauai's older north and west shore homes often still run original cloth-sheathed or aluminium branch wiring, and heavy rain means outdoor circuits need real weather-rated covers, not the flat snap-shut kind.

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

What Koloa customers say

★★★★★

Had three other companies look at a flickering light problem. These guys found an open neutral in a junction box behind a closet in about twenty minutes.

Landscape lighting along the driveway. They buried everything properly instead of stapling it to a fence.

Electrical Panel Upgrade in Koloa: frequently asked questions

How do I know my Koloa 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 Koloa?
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 Koloa?
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 Koloa?
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 Koloa?
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 Koloa?
Not usually all day. We plan the outage window with you in advance so you can move anything temperature sensitive first.
Do you handle both homes and businesses in Koloa?
Yes. Residential work in Koloa runs from single repairs to full rewires. Commercial work covers offices, restaurants, retail and warehouses, usually scheduled after hours so you do not lose trading time.
Can you upgrade my panel and add an EV charger at the same time in Koloa?
That is usually the cheapest way to do it. One mobilisation, one load calculation, one inspection. We size the service for the charger plus anything else you are planning, such as a mini split or induction range.
