Notes

  • Where the number comes from. The national price for a 100-amp panel upgrade is $1,700 installed — service panel upgrade pricing published for 2026. Labor is about 68% of that. Electricians near Tri-Cities, WA average $94,470 a year against a U.S. mean of $71,490 — a factor of 1.321 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for electricians near Tri-Cities, WA, so this is the Washington state average, SOC 47-2111.
  • This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Tri-Cities, WA, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
  • What is in the price: the panel, breakers, a new meter base, grounding electrodes, the service mast, permit inspection time, and labor.
  • What is not: the utility drop, trenching for an underground service, any rewiring inside the house, and repairs to walls the mast passes through. These are the lines that turn a $2,072 quote into a $2,589 invoice, so ask about each one before signing.
  • Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average for the job.

What the quote should include

The lines that turn a quote into an invoice

Ask about each of them before you sign. On a job this size they are the difference between $2,072 and something a quarter higher.

Use it as a bid check, not a quote

This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.

If a bid lands outside $1,462 – $3,046, that is not automatically wrong — but it is the question worth asking out loud.
