Modernize your home's power.
Electrical panel upgrade in Seattle: 100A to 200A or 400A service, breaker box replacement, sub-panels for additions and ADUs, and full rewires for homes still running cloth or knob-and-tube. Permitted and inspected.
If your house was built before the 1990s, there's a real chance your electrical panel is doing more work than it was ever designed for. A 100-amp panel was plenty when "electrical demand" meant a fridge, a dryer, and a window AC. Now you're trying to add a heat pump, an EV charger, an induction range, and a finished basement — and the panel is full, the bus is rated for half what you're pulling, and the breakers trip every time someone runs the microwave and the toaster at the same time.
That's when you need an electrical panel upgrade in Seattle, and that's the kind of work Mad Dog Electric does most weeks. We handle the full panel job: upgrades from 100A to 200A or 400A service, breaker box replacement, sub-panels for additions and ADUs, GFCI/AFCI retrofit, and full rewires for homes still running cloth or knob-and-tube.
We're licensed and bonded in Washington, every job is permitted, and we coordinate with Seattle City Light, PSE, or your utility for the meter pull and re-energize.
Why Mad Dog
EV charger, heat pump, induction range, hot tub — modern homes pull more amps than 1970s panels were designed to handle. We bring it up to today's demands.
All work meets or exceeds current NEC and Seattle DCI requirements. AFCI/GFCI breakers where required. Ground rods, water-pipe bond, and rebar bond brought up to code.
Many WA insurers won't write or renew on Federal Pacific, Zinsco, Pushmatic panels or active knob-and-tube. We give you documentation to send your insurer.
We handle the meter pull and re-energize with Seattle City Light, PSE, or Snohomish PUD. Power off in one block, not all day.
Do You Need This?
Some of these are obvious; some sneak up on people. If any sound familiar, get a panel evaluation:
The Mad Dog Guarantee
How It Works
We inspect the panel, service entrance, and grounding. Line-by-line quote so you can see what's driving the number.
We pull the L&I permit and schedule the meter pull with your utility. Power off in one daytime block, not spread across the day.
Old panel out, new 200A (or 400A) panel in, breakers populated, grounding brought to current code, service entrance updated where needed.
We meet the L&I inspector. Then walk you through the new panel, label every breaker, and hand over the paperwork.

Permits & Code
Yes, panel work requires an L&I electrical permit and inspection in Washington. Anyone offering to do this without a permit is a red flag — it'll fail at sale, the insurance won't cover a fire, and you'll pay twice. Our prices include the permit. Seattle properties under Seattle DCI also follow local amendments — we handle those too.
From the Field
Straight from the truck — actual panels & remodelswork we've done around the greater Seattle area.
On one job, a standard panel replacement would have come with about $3,000 in added fees. We performed a live panel swap instead — safely replacing the panel while it stayed energized — and saved the homeowner that $3,000.
One of our toughest early jobs had the existing service panel on the wrong side of the house for the remodel. We relocated the entire service to the opposite side — re-routing the service entrance and circuits — and brought everything up to current code.
“I had a wonderful experience with Mad Dog Electric. They were recommended to me by friends who were very happy with their service, so I decided to call. David answered right away and was very friendly, professional, and easy to talk to. He took the time to understand what I needed and explained everything in a clear, simple way. We scheduled a consultation, and he arrived on time, inspected everything efficiently, and gave me very helpful advice. He explained the best options for my situation, the possible price range, the steps of the work, and what would be involved both on his side and with the city. I really appreciated how patient, honest, and knowledgeable he was. David was a pleasure to work with, and I would gladly recommend him to anyone looking for a reliable electrician. Thank you very much, David!”
