Panel Changes & Upgrades

An undersized or aging panel limits what your property can do and can be a real safety hazard. We upgrade panels and service capacity to handle today's loads — EV chargers, HVAC, shop equipment, and more.

We manage the utility coordination, permits, and inspection, and leave you with a clearly labeled, code-compliant panel built for the future.

Who this is for

Your panel is a Federal Pacific Stab-Lok or a Zinsco

You're adding a heat pump, EV charger, or hot tub and need capacity

Breakers trip repeatedly, or the panel is warm to the touch

Your insurer or home inspector has flagged the panel

What's included

  • Service & panel upgrades
  • Increased capacity
  • Utility coordination
  • Clear labeling & inspection
  • Federal Pacific & Zinsco panel replacement
  • 100A to 200A+ service upgrades
  • Meter base replacement
  • Sub-panel installation
  • Breaker & circuit relabeling

How long it takes

Recent Panel Changes & Upgrades jobs have taken 1–3 days, depending on scope. Permit and inspection scheduling is handled as part of the job and doesn't add to your timeline beyond what the utility or inspector requires.

What a panel upgrade costs

$2,500 – $3,500 What our own customers paid for a 100A → 200A service upgrade, Portland metro and Clark County

  • Like-for-like panel replacement $2,300 – $3,000

    Same amperage — the usual Federal Pacific or Zinsco swap.

  • 100A → 200A service upgrade $2,500 – $3,500

    New 200A panel and main, new meter socket, utility coordination. Median job: $3,000.

  • Full service upgrade — new mast, weatherhead and grounding From $6,000

    Overhead service rebuilt end to end, grounding brought to code. Priced after a site visit.

  • Panel relocation + $2,000 – $4,000

    Added to the above — every circuit re-routes to the new spot.

  • Subpanel for a garage, shop or ADU $800 – $1,800+

    Priced by feeder length and whether it has to be trenched.

  • 400A service $7,000 – $12,000+

    Large homes, shops, multiple EVs; utility transformer coordination.

Permit and inspection are part of the job — we bill $350 – $750 depending on jurisdiction and scope. (The City of Portland fee alone is $239; Clark County is $121.50 for 0–200A.)

These ranges are a starting point, not a quote. The exact price for your job can only be set after we talk it through — call or send the form and you’ll have it as a free written estimate before any work starts.

The panel replacement and 100A → 200A rows come from our own paid invoices, August 2024 – August 2026. The rows below them are planning estimates — those jobs are priced individually after a site visit.

Answers

Panel Changes & Upgrades FAQ

01How do I know if my panel needs replacing?
Frequent tripped breakers, a warm panel, visible rust or scorching, or an insurer/inspector flag are all signs it's time.
02Are Federal Pacific and Zinsco panels really unsafe?
Both brands have a well-documented history of breakers failing to trip properly, and most insurers and inspectors flag them.
03Will I lose power during the upgrade?
Yes, briefly — we coordinate with the utility to minimize the outage window during the swap.
04Do you handle the utility disconnect and reconnect?
Yes, that coordination is part of the job.
05Can you upgrade my service size (e.g. 100A to 200A)?
Yes, we size the new service and panel to match your current and future load needs.
06Do I need a permit for a panel upgrade?
Yes, and we pull it and coordinate the inspection as part of the job.
