Electrical Work for Seattle's Electrified Future

Seattle's electrical moment is electrification. Across the city, oil furnaces are giving way to heat pumps, gas ranges to induction, and garages to EV chargers. Seattle City Light serves much of the city, and the policy wind is at the back of every conversion. But there is a catch hiding in the basement: most of Seattle's craftsman, bungalow, and mid-century homes run on 100-amp panels designed for a fraction of today's electrical life. Electrical Service Precision Pros is the electrical half of that transition.

The math is straightforward and unforgiving. A whole-home heat pump needs a dedicated circuit sized to the equipment. An EV charger needs a 240-volt circuit of its own. Add induction cooking, a home office, and the ADU in the backyard, and a 100-amp service is simply out of room. We run real load calculations against your HVAC contractor's equipment specs. Where the numbers demand it, we upgrade to 200 amps — with SDCI permits pulled and Seattle City Light coordination handled by us.

The old wiring is the other half of the Seattle story. A century of craftsman and bungalow construction left knob-and-tube and early cloth cable buried under decades of remodels, and the damp never stops working on it. We trace every live run and replace what is dangerous, fishing new grounded cable through plaster walls with the restraint these houses deserve. The woodwork never knows we were there.

Rain shapes every detail. Nine months of damp attacks exterior equipment: meter sockets corrode, ground clamps rust, outdoor receptacles fail. Our baseline for exterior work is sealed and corrosion-proof — every fitting, not just the visible ones. Exterior outlets get wet-location GFCI devices. Work that ignores Seattle rain gets done twice — we build it once, for the damp.

The ADU boom adds a distinctly Seattle chapter. Basement apartments, backyard cottages, and garage conversions each need their own panel or subpanel, proper metering, and dwelling-unit code compliance — GFCI, AFCI, and interconnected smoke and CO protection. We design ADU electrical from the service entrance outward, permit it through SDCI, and deliver a second dwelling whose power is as safe and legal as the main house.

The city's electrification push keeps accelerating: heat pumps replacing gas furnaces, induction ranges, EVs in every driveway. Each conversion adds load to panels designed when a 60-amp service was generous. The heavy-up is becoming Seattle's most common electrical project, and we do them daily.

Seattle's Most Common Electrical Problems

Panels too small for the electrified home

Seattle is electrifying fast. Heat pumps are replacing oil and gas heat across the city, induction ranges are landing in renovated kitchens, and EV chargers are going into Ballard and Wallingford garages. The pinch point is the panel: craftsman and mid-century homes typically carry 100-amp services, and a heat pump plus a charger plus modern life will not fit. We are the electrical half of the electrification equation. That means load calculations, service upgrades to 200 amps, and dedicated circuits for heat pumps — coordinated with your HVAC contractor so the equipment and the panel agree.

Rain corroding exterior equipment year-round

Seattle rain is gentle and relentless, and it is brutal on exterior electrical equipment. Moisture seeps into meter sockets, outdoor panels, and receptacles; ground clamps corrode in the constant damp; and junction boxes in crawl spaces turn green with oxidation. The symptoms are seasonal: GFCIs that trip on wet days, flickering exterior lights, and corrosion discovered during panel upgrades. We rebuild with weather-rated, sealed enclosures, corrosion-resistant grounding hardware, and exterior devices rated for wet locations. Seals, ground clamps, and receptacle covers wear out on a schedule here. We recommend a look at exterior equipment every few years — catching it early is cheap insurance against the seasonal trip-and-flicker cycle.

Aging wiring in craftsman neighborhoods

Ballard, Wallingford, Queen Anne, West Seattle — the craftsman and bungalow neighborhoods are full of knob-and-tube and early cloth wiring, often buried under decades of remodels. Year-round moisture breaks down the old cloth insulation. Every live circuit gets mapped, the dangerous sections come out, and new grounded cable fishes through plaster with minimal patching. The fir floors and moldings survive. The wiring becomes something a home inspector praises instead of flags.

ADU and backyard cottage electrical

Seattle's ADU and DADU boom — basement apartments, backyard cottages, garage conversions — creates a specific electrical challenge: a second dwelling on the same service. Each unit needs its own panel or subpanel, proper metering, and circuits that meet code for dwelling units. We design ADU electrical systems from the service entrance outward. That covers load calculations for the combined load, subpanels with correct feeder sizing, and all the GFCI, AFCI, and smoke and CO protection the code requires. Done right, the cottage is as safe and legal as the main house.

SDCI permits and inspections done right

Seattle Department of Construction and Inspections takes electrical permits seriously, and service upgrades, new circuits, and panel replacements all require them. The process rewards contractors who file correctly and punishes those who do not — failed inspections delay projects and complicate sales. We pull SDCI permits routinely, schedule inspections, and build every job to pass the first time. Seattle City Light handles the disconnect and reconnect; we schedule our work around their window. The paperwork is invisible to you and airtight for the record.

Seattle City Light Service Upgrades and Meter Approvals

Seattle City Light approves every service upgrade, including the meter location itself. Their inspectors want the meter spot confirmed before we start, and the disconnect runs on their schedule. We submit the application, rebuild the mast, socket, and grounding to their spec, and sequence the city inspection for same-day reconnection. Older homes with 60-amp services and original sockets get the full rebuild. The paperwork never touches your desk.

Windstorm Outages and Generator-Ready Panels

Pacific Northwest windstorms knock out power for days, and Seattle's tree canopy makes it worse. A standby generator with an automatic transfer switch keeps the essentials running: fridge, furnace, sump pump, lights. For smaller budgets, we install generator-ready panels with interlock kits that accept a portable safely. Either route ends the extension-cord gamble. When the next windstorm hits, you choose comfort instead of coping.

How Your Seattle Project Moves Forward

1

Tell us what you are electrifying

Start with (833) 606-5080 or info@electricalserviceprecision.com: tell us the plan — heat pump conversion, EV charger, ADU, or a straightforward repair. We ask about the home's age and the panel, plus equipment specs if you have them, then book the visit. Heat pump projects get timed with your HVAC contractor from the start.

2

Inspect, measure, and run the numbers

The panel gets opened and tested under load, exterior equipment gets checked for moisture damage, and old wiring gets traced where relevant. For heat pumps, EV chargers, and ADUs we run a load calculation against the actual equipment specs. We also assess grounding and the service entrance condition, since both limit what the upgrade can carry. You get written findings with photos and a clear answer on capacity.

3

Fixed quote with electrification phases

The number is fixed and itemized — labor, materials, and SDCI permit fees each on their own line. Electrification projects often phase: panel upgrade now, ADU wiring later, with each phase carrying its own quote. What you approve is what you pay.

4

Permitted, inspected, and future-ready

Permits go through SDCI, the work goes to code, and we meet the inspector ourselves. Service upgrades get Seattle City Light's disconnect and reconnect coordinated into the schedule. After passing, every circuit is tested, heat pump and charger circuits are verified under load, and the panel is labeled. The permit record stays with you, along with a panel ready for whatever electrification comes next.

Client Experience

What to Expect Working With Us

"We were converting from oil to a heat pump and the HVAC contractor flagged our 100-amp panel immediately. They ran the load calculation, upgraded us to 200 amps, pulled the SDCI permit, and coordinated with Seattle City Light. The heat pump went in on schedule and the inspector passed everything first try."

- Craftsman owner in Ballard

"Our backyard cottage needed its own electrical setup and I had no idea where to start. They designed the whole thing — subpanel, metering, all the code requirements for a dwelling unit — and permitted it through the city. The cottage feels like a real home now, not an afterthought."

- Homeowner in West Seattle

"Our 1920s bungalow had live knob-and-tube that two home inspectors had flagged. They traced every run, rewired in phases, and the plaster damage was minimal. The fir trim is untouched. For the first time, I am not nervous about what is behind the walls."

- Bungalow owner in Wallingford

Serving Seattle and the Puget Sound

Our Seattle base covers Ballard and Fremont's craftsman blocks, Wallingford and Green Lake's bungalows, and Queen Anne's historic homes. West Seattle's mixed housing, Capitol Hill's older buildings, and the south end's ranch neighborhoods round out the city proper. The work follows the city's electrification wave: heat pump panel upgrades, EV charger circuits, ADU wiring, and careful rewiring of the old stock.

Frequently Asked Questions

Start with what the panel actually has left. A lone mini-split head often squeezes onto a modern panel with open slots — no upgrade needed. What breaks the math is the double: a whole-home heat pump and an EV charger together on a 100-amp craftsman service. We take your HVAC contractor's equipment specs, run a real load calculation, and tell you straight. Oil-to-heat-pump conversions are when most Seattle homeowners land on 200 amps.
Just about every time. Under SDCI rules, panel replacements, service upgrades, new circuits, and ADU electrical all need permits and inspections — licensed-electrician work, full stop. We file the permits and stand by for the inspector on every job. Permitted work protects resale and keeps insurers comfortable; in this market, unpermitted electrical turns into a sale-time liability.
Yes — ADU electrical is a specialty of ours. For the cottage or basement unit, we start at the service entrance and work outward. One load calculation covers the whole property, then the right panel arrangement, separate metering, and full dwelling-unit compliance. We permit it through SDCI and coordinate the inspection. The result is a second dwelling with properly metered, fully code-compliant power.
Usually in stages, and Seattle's damp makes it worth scheduling sooner than later. The rule is simple: knob-and-tube cannot extend anywhere new or hide under insulation, and cloth insulation rots fast in year-round moisture. We start with a full map — every live run located — then pull the dangerous circuits first and stage the rest around your budget and renovation plans. Almost everything goes through small openings we patch ourselves, so plaster stays plaster and the fir trim survives.
It scales with the job: service size, the state of the existing wiring, how much old cable gets replaced, and the SDCI permit fees. A straight panel swap is one price; an upgrade that also powers a heat pump and an ADU is another. The visit sets it: after we see the house, you get the number in writing, fixed. (833) 606-5080 is the way in.
Yes — rain-city grids surge more than people expect. Storms and restoration swings send spikes through Seattle homes every year. A protector mounted at the panel covers all the circuits together: heat pump controls, electronics, appliances. We add one during most panel upgrades and check the grounding it relies on.
Seattle City Light and other regional utilities run rebate programs for heat pump conversions. Federal tax credits have applied to qualifying equipment and panel upgrades too — but programs and amounts change regularly. We help you understand the electrical side: what the panel must carry and what the upgrade involves. Check your utility's current program details before planning, and we will make sure the electrical work qualifies where it can.
Diagnosis comes before devices. We assess the wiring condition and the grounding first, then usually guard the circuits with GFCI breakers at the panel — the quickest win in a city this damp. Real grounded receptacles are a different project: they need new cable, ideally pulled while walls are open during a renovation. Outside, we mount weather-rated GFCI outlets in sealed, in-use enclosures that shrug off sideways rain. To get started, email info@electricalserviceprecision.com with your address and we will book the assessment.
Heavy-up is the local term for a service upgrade, going from 60 or 100 amps to 200. Your home needs one if the panel is full, breakers trip regularly, or you are adding a heat pump, EV charger, or ADU. We do a load calculation and tell you straight. Many Seattle homes built before 1970 are overdue.
Yes, and it is a smart electrification move. Heat-pump water heaters need a dedicated 240-volt circuit, and we verify your panel has the capacity first. They sip electricity compared to old resistance tanks. We run the circuit, set the disconnect, and coordinate with your plumber's install. Your water heats on Seattle's clean power.
