Why it matters
Why panel upgrades & replacements is worth doing right
If you are adding an EV charger, a heat pump, a hot tub, or a kitchen full of new appliances, your panel is what has to carry it. Many Renton-area homes still run a 60 or 100 amp service with no spare breaker space, and some still have panels that have been recalled for years.
We do not upsell amperage you will never use. We run the numbers, tell you whether 100, 200, or 400 amp service is the honest answer for your home, and land every circuit torqued, labeled, and tested.
Warning signs
Signs you need a panel upgrade
A panel rarely fails all at once. These are the warning signs we get called for most:
- Breakers that trip repeatedly, or won't reset
- Lights that flicker or dim when the AC, dryer, or microwave starts
- A Federal Pacific, Zinsco, or fuse-based panel (known safety risks)
- A warm panel cover, buzzing, or a burning smell at the box
- Scorch marks, rust, or corrosion inside the panel
- No open breaker slots left for a new circuit
- Adding an EV charger, heat pump, hot tub, or shop
- A 60 or 100 amp service in an all-electric home
How it works
What to expect with panel upgrades & replacements
- 01
Load assessment
We measure what your home actually draws and what you're adding, then size the service so it's neither undersized nor wastefully oversized.
- 02
Permit & utility
We pull the electrical permit and coordinate the power shut-off with the utility so the cutover is clean and legal.
- 03
Swap & re-land
We mount the new panel, re-land every circuit, and bring grounding and bonding up to current code.
- 04
Label, test, inspect
Every breaker is labeled and tested, and we schedule the inspection so your upgrade is signed off.

The right service size depends on your home and your plans, not a default. Here's how we frame it:
Fair, upfront pricing
What affects the cost
We quote every panel after we see it. The factors that move the price:
- Service size (100 vs 200 vs 400 amp)
- Whether the meter base and service entrance also need replacing
- Overhead mast vs underground service
- Aluminum vs copper service feeders
- Permit and inspection fees
- Any drywall or siding repair around the panel

Questions
Common questions about panel upgrades & replacements
Do I need a permit to replace my electrical panel?
Yes, and we pull it for you. A panel swap requires a permit and an inspection in Washington, and we handle both as part of the job so the work is signed off and legal.
Is a Federal Pacific or Zinsco panel really dangerous?
These panels have a documented history of breakers that fail to trip under a fault, which is a real fire risk. If you have one, we recommend replacing it, and we'll show you what we find.
How long does a panel upgrade take?
Most residential panel replacements are a one-day job, including the inspection in many cases. We confirm the timeline after we assess your service and coordinate the utility shut-off.
Will my power be off during the upgrade?
Yes, for part of the day while we make the cutover. We plan the shut-off with you and the utility ahead of time so you're not caught off guard.
Do I really need 200 amp service?
Not always. If you're all-electric or adding an EV charger or heat pump, 200 amp is usually the right call. If not, we won't upsell you capacity you'll never use.
