Quick answer
It depends on whether the problem is a part or the panel. One worn breaker, a loose lug, or a failed connection is a repair — a parts-and-labor visit that ends with a torque check and a clean bill of health. Widespread heat damage, corrosion, a fuse box, or a recalled brand (Federal Pacific, Zinsco) is a replacement conversation: $4,000–$9,000 installed for a 200-amp panel in the Puget Sound. A licensed diagnosis, not the symptom, tells you which side you're on.
- A single tripping breaker is often a $-hundreds repair — the breaker itself, a loose connection, or a circuit problem masquerading as a panel problem.
- Heat discoloration, buzzing from multiple positions, corrosion, or repeated nuisance trips across circuits point at the panel as a system — that's replacement territory.
- Federal Pacific Stab-Lok and Zinsco panels have documented failure-to-trip histories; component repairs inside them don't fix the underlying design.
- A like-for-like 200-amp panel replacement typically runs $4,000–$9,000 installed here; it's the moment grounding, bonding, and surge protection get brought to current code.
- Replacement is also the natural time to plan capacity: if a heat pump or EV charger is coming, size the decision once.
What does each option cost installed in the Seattle area?
Repair pricing is diagnosis-driven — what failed and how accessible it is — while replacement is a defined project. What you should never pay for is repeated repairs to a panel that has already declared itself done.
| Option | Typical installed range | What that covers |
|---|---|---|
| Component repair (breaker, lug, connection) | Diagnosis-priced — commonly a few hundred dollars | A failed breaker swap, a re-torqued or repaired connection, or a corrected double-tap. Quoted upfront after diagnosis; done same-visit in most cases. |
| Panel replacement (200A, same service) | $4,000–$9,000 | New panel and breakers, grounding and bonding to current code, labeling, permit, and inspection — service size unchanged. |
| Service upgrade (100A → 200A), if capacity is also the problem | $8,000–$16,000 | When the diagnosis shows both a failing panel and a load calculation that exceeds the existing service — one project instead of two. |
What changes the price
- What the diagnosis finds: one bad component versus systemic heat damage or corrosion.
- Panel brand and era: recalled designs shift the answer to replacement regardless of the immediate symptom.
- Aluminum branch wiring or double-taps discovered during the visit — correcting them is part of doing the job safely.
- Panel location and wall finish: flush panels in finished walls add patch scope.
- Permit authority (city program vs state L&I vs Tacoma Power) sets the inspection path and timeline.
Ranges are representative Seattle / Puget Sound installed prices, not a quote — your home's specifics set the real number. Eco gives you an upfront price before any work begins.
How do they work differently?
What a panel repair actually is
Breakers are replaceable components: they wear out, and a failed one is swapped in minutes once diagnosed. The same goes for a loose neutral, a heat-damaged lug, or an improperly doubled-up circuit. The essential part is the diagnosis around the fix — verifying the failure was the component, not a symptom of the bus or the connections behind it.
What replacement fixes that repair can't
The bus bars, the enclosure, and the design itself. Once heat or corrosion has damaged the bus, every new breaker inherits a bad connection point. And recalled designs fail at the one job that matters — tripping under fault — which no component swap changes. Replacement resets the whole system to current code, including grounding, bonding, and AFCI/GFCI protection.
Pros and cons, honestly
Component-level repair
Pros
- Fast and inexpensive when the diagnosis supports it
- Restores full function of a fundamentally sound panel
- No permit-scale project for a part-scale problem
Cons
- Cannot fix bus damage, corrosion, or recalled designs
- Repeated repairs on an aging panel add up to replacement money without the result
- A repair on a failing panel can mask a hazard instead of removing it
Full panel replacement
Pros
- Retires the hazard class entirely — new bus, breakers, and code-current protection
- Insurance and resale friction from fuse boxes and recalled brands goes away
- The natural moment to add whole-home surge protection and plan capacity
Cons
- Real project cost ($4,000–$9,000) and a scheduled power-off day
- Overkill when the honest diagnosis is one worn component
- Finished-wall locations add patching to the scope
Which one should you choose?
When repair wins
The panel is a sound, modern design and the diagnosis isolates a single failed component — one breaker, one connection, one corrected double-tap. You pay for the fix and the verification, and the panel goes back to being boring.
When replacement wins
The panel is a fuse box or a recalled brand; there's heat damage, corrosion, or buzzing beyond one position; trips are spreading across circuits; or this is the second or third repair visit to the same box. At that point each repair is a payment on a panel you've already decided to replace.
Also consider: capacity while you're there
If the same visit's load calculation shows electrification plans exceeding your service, compare the 100A→200A service upgrade before replacing like-for-like — the 200-amp-vs-100-amp comparison covers that decision.

Common questions
My breaker trips every time two appliances run — repair or replace?
That pattern is usually an overloaded circuit, not a broken panel — the breaker is doing its job. The fix may be as simple as a dedicated circuit, or it may reveal a panel with no room for one, which is where the replacement conversation starts. Either way it begins with a diagnosis, not a teardown.
How do I know if my panel is one of the recalled brands?
Open the door and read the label: Federal Pacific (often marked Stab-Lok) and Zinsco are the two with documented failure-to-trip histories. If you see either, or a fuse box, it's worth a licensed assessment even with no symptoms — the risk is exactly that they fail silently.
Where do these price ranges come from?
They're Eco's current installed ranges for Puget Sound homes — the same client-verified figures published on our electrical panel cost guide — including permits and inspection. Repairs are priced upfront after diagnosis, before any work starts.
Can I just replace the breakers instead of the panel?
If the bus and enclosure are sound, yes — breakers are serviceable parts. But new breakers snapped onto a damaged or recalled bus inherit its problems. That's the line between a repair that fixes and a repair that postpones.
