An electrical service panel is the single most important component of your home's electrical system. It is also the component most homeowners never think about until a breaker stops holding, a Federal Pacific panel becomes uninsurable, or an EV charger or heat pump install reveals that the existing service simply cannot carry the load. Panel upgrades sit at the intersection of safety, capacity, code compliance, and resale value — and they are the most over-priced and over-upsold service in the residential electrical trade.
We do this work flat-rate. Every quote is provided in writing before any drywall is touched. The price you accept is the price you pay. The work is performed by Washington-licensed electricians, permitted with the appropriate authority, and inspected by the local jurisdiction. No commission salespeople. No "while we're here" upsells. Just the upgrade your service needs, sized to your actual current and future load.
When You Actually Need a Panel Upgrade
Most panel upgrades fall into one of five honest categories. If you are being told you need a panel upgrade and your situation does not fit one of these patterns, get a second opinion before signing anything.
1. Your service capacity is insufficient for current or planned load
A typical 1960s or 1970s Eastside home was built with a 60-amp or 100-amp service. That was reasonable when a home ran a furnace, a refrigerator, an electric range, and a handful of incandescent fixtures. It is no longer reasonable when the same home is asked to support a heat pump (40–50 amps continuous), a Level 2 EV charger (40–60 amps dedicated), an induction range (40 amps), a heat pump water heater (30 amps), and a home office of always-on electronics. Adding any one of these to a 100-amp service triggers a load calculation; adding two or three pushes most pre-2000 panels past their design capacity.
A 200-amp upgrade is the modern Eastside baseline. It supports the full electrification path most homes are now on (heat pump heating and cooling, EV charging, electric cooking, electric water heating, future battery storage) without forcing a second upgrade in five years. 400-amp services are appropriate for larger custom homes, properties with detached ADUs or shops, or commercial spaces with significant equipment loads.
2. Your panel is a Federal Pacific Stab-Lok or Zinsco
Federal Pacific Electric Stab-Lok panels and Zinsco panels are documented fire hazards. Both have failure modes where breakers fail to trip under fault conditions, allowing wiring and connected equipment to overheat. Independent testing has demonstrated this conclusively, and most home insurers in Washington will not write or renew policies on homes with either brand still in service.
If you have one of these panels, replacement is not optional. It is also not an emergency in the literal sense — these panels have been in service for decades and the failure rate per day is low — but it is a known liability that any homeowner should resolve on a planned, permitted, and inspected basis rather than an emergency basis after a fire.
3. Your panel is full and you need additional circuits
"Full panel" is the most commonly fabricated panel-upgrade pitch. The actual question is not whether your panel is physically full of breakers — that condition is easily addressed with tandem breakers, sub-panels, or breaker consolidation — but whether your panel can mathematically accept the additional load you need to add under a load calculation. The two are different problems with different solutions, and a 200-amp upgrade is only the right answer when the underlying service capacity is genuinely the bottleneck.
4. Your panel is damaged, corroded, or showing signs of failure
Burn marks around breaker connections, melted plastic, rust on the bus bars from water intrusion, breakers that trip under no apparent load, and panels that hum or buzz are all signs that components are failing or have failed. These are real safety issues and warrant immediate inspection and, frequently, replacement.
5. The service entrance, meter base, or mast is failing
Sometimes the panel itself is serviceable but the wiring between the utility and the panel — the service entrance cable, meter base, or weatherhead and mast — has deteriorated to the point of needing replacement. In many cases the same project that addresses the service entrance also justifies a full panel upgrade, since the cost overlap is significant.
What's Included in a Standard Panel Upgrade
Our flat-rate panel upgrade quotes include the work described below as standard. Anything outside this scope is documented and quoted separately before work begins; nothing is added without your written approval.
- Site visit, load calculation, and written flat-rate quote
- Electrical permit pulled with the appropriate jurisdiction (WA L&I, City of Bellevue, City of Redmond, City of Kirkland, etc.)
- Utility coordination for power disconnect and reconnect
- Removal of the existing panel and connected components
- Installation of new panel (200A or 400A as specified), with the correct main breaker, bus, and grounding/bonding configuration
- Re-termination of every existing branch circuit to the new panel, with each circuit clearly labeled
- Installation of whole-home surge protection at the new panel as standard
- New grounding electrode conductor and ground rod where the existing grounding does not meet current code
- Replacement of any service entrance cable, meter base, or mast where deteriorated
- Final inspection scheduling and any corrections required by the inspector
- Cleanup and removal of all old equipment and packaging
- One-year workmanship warranty
The standard you should expect
Every panel we install is labeled with a typed or professionally hand-printed circuit directory accurate to the room and fixture. Breakers are arranged in functional groups. Conductors are dressed inside the panel — not crammed in like a bird's nest. The cover sits flush. The work passes inspection on the first attempt. This is the minimum standard for a panel that you will live with for the next thirty years.
What a Panel Upgrade Actually Costs in the Greater Eastside
Honest pricing requires honest disclosure. The variables below determine where in the range a given upgrade lands. Final flat-rate pricing is provided in writing only after a site visit, never quoted blind over the phone.
| Configuration | Typical range |
|---|---|
| 100A to 200A upgrade, existing service entrance reusable | $2,400 – $3,800 |
| 200A upgrade with new meter base or mast | $3,800 – $5,800 |
| 200A upgrade requiring new service drop coordination with PSE | $4,500 – $6,500 |
| Federal Pacific or Zinsco replacement, 200A new panel | $3,200 – $5,200 |
| 400A residential service upgrade | $6,500 – $8,500 |
Ranges reflect typical Eastside residential conditions. Commercial panel upgrades, panels in difficult-access locations, panels requiring extensive sub-panel reconfiguration, and panels with significant code corrections to existing branch circuits fall outside these ranges and are priced individually.

The Permit and Inspection Process
Panel upgrades are permitted work in every Washington jurisdiction. Cities that operate their own electrical inspection program — Bellevue, Seattle, and a few others — require a permit and inspection through the city. Cities that defer to the state — most of the smaller Eastside municipalities — use the Washington Department of Labor & Industries electrical permitting and inspection program. Either way, we pull the permit on your behalf, schedule the inspection, and address any corrections noted by the inspector at no additional charge if they arise from our work.
Unpermitted panel work creates two long-term problems. First, the work is not inspected by a qualified third party, which removes the safety net that catches errors before they become hazards. Second, unpermitted work must be disclosed at the time of resale in Washington and is a frequent source of failed escrow conditions. The savings from skipping a permit are almost always negative when this comes due.
What Happens During Installation Day
A typical residential panel upgrade follows a predictable schedule. Knowing the timeline up front makes the day far less disruptive.
- Pre-arrival. The permit is filed, the inspection is scheduled, and the utility disconnect is coordinated (when required). You receive a confirmation the day before with the arrival window.
- Arrival and setup. The crew arrives, walks the existing panel with you, confirms scope, and stages materials. Total: 30–45 minutes.
- Power down. The utility-side disconnect is verified, the main is opened, and power is off to the house. Total power-off time is typically 4–6 hours for a straightforward upgrade.
- Removal. Old panel is photographed for circuit reference, then each branch circuit is disconnected and labeled. Old panel and components are removed and set aside.
- New panel installation. Panel is mounted, main breaker installed, bus and grounding bonded per code, and the panel directory is started.
- Re-termination. Each branch circuit is dressed, terminated to the appropriate new breaker, and labeled. This is the most time-intensive part of the work and the part that most distinguishes a good install from a sloppy one.
- Service entrance and grounding. Service entrance cable, meter base, or mast replaced if in scope. New ground rod driven and bonded if the existing grounding does not meet current code.
- Power up and testing. Utility power is restored. Each circuit is energized in turn, voltage and continuity tested, GFCI/AFCI breakers function-tested. Any anomalies investigated before the crew leaves.
- Cleanup and walkthrough. All old equipment removed. Panel directory finalized and printed. Walkthrough with you covering breaker locations and surge-protection function.
- Inspection. Inspector visits at the scheduled time. Most panels pass first inspection; corrections, if required, are made within a few business days at no additional charge.
Common Questions Before You Schedule
The five most common questions homeowners ask us about panel upgrades, with honest answers.
How long will my power be off?
Most of the workday for a standard 200-amp upgrade. Plan for 4–6 hours of no power during the active replacement phase, with intermittent shutoffs at the start and end of the day for safety testing. For homes with home offices or critical medical equipment, we can arrange temporary generator power for a portion of the day at additional cost — discuss this with us during the site visit.
Will my appliances and electronics be affected?
Modern appliances handle clean power-off and power-on cycles without issue. Older equipment with mechanical timers or memory components occasionally need to be reset (microwaves, ovens, alarm clocks). We do not unplug or move your equipment as part of the panel work — that responsibility stays with you.
Do I need to be home during the work?
Someone over 18 should be present at arrival to confirm scope and at completion for the walkthrough. The middle of the day does not require your presence. The inspector, however, must be granted access at the scheduled inspection appointment, which is usually a separate day.
What if the inspector fails the work?
It is uncommon, but inspectors occasionally cite items that require correction. Corrections to our workmanship are made at no additional cost. Corrections to pre-existing conditions outside our original scope (existing branch-circuit code violations behind walls, for example) are quoted as a change order before the related correction proceeds, and you choose whether to authorize it.
How quickly can you schedule a panel upgrade?
Permitted panel upgrades typically schedule 7–14 days out depending on jurisdiction permit-turnaround times and our crew calendar. Emergency replacement of failed or fire-damaged panels is dispatched within 24 hours.
