Reliable Power Solutions for Seattle Properties

Serving neighborhoods from Capitol Hill to Ballard and across the broader Seattle metro, Konsker Electric has been the city's trusted licensed electrician for over 20 years of residential and commercial work.

Seattle's 150+ days of measurable rain annually make moisture management in electrical systems a critical concern — proper sealing and GFCI protection are non-negotiable.

Our crews work daily near Capitol Hill, Ballard, and the broader Seattle metro and throughout the Seattle neighborhood, so we know the local permit office, the common service-drop layouts, and the building stock — Seattle features everything from historic brick rowhouses to modern ADUs and high-rise condos. Every installation is tailored to the property's specific age, wiring type, and electrical load requirements — backed by full warranty and code-compliant permits.

Your Trusted Seattle Electrician

Seattle's electrical needs are as varied as its neighborhoods. A 1908 Craftsman in Wallingford with knob-and-tube in the attic, a 1920s brick four-square in Mount Baker on a 60-amp Federal Pacific service, a 1970s split-level on Beacon Hill, a brand-new ADU in Greenwood, a high-rise condo in Belltown — each has a completely different starting point, code path, and inspection workflow. Konsker Electric has been the licensed electrical contractor for Seattle homeowners across all of these for more than 20 years, and we hold an active Washington State L&I master electrician license, full bonding and insurance, and Seattle Department of Construction & Inspections (SDCI) electrical permitting accounts for every job we file.

Seattle is unique in the region because the city runs its own electrical inspection program through SDCI rather than deferring to L&I. That means every service change, panel swap, ADU, and rewire in the city limits is permitted through SDCI's electrical division, inspected by a city electrical inspector, and metered by Seattle City Light rather than PSE. We file the permits, schedule the inspection, walk the inspector through the install, and handle the SCL service-disconnect coordination — homeowners never have to call the city or the utility themselves.

The city's 150+ measurable rain days and persistent winter humidity mean every exterior penetration, weatherhead, meter base, and outdoor receptacle has to be sealed and flashed correctly the first time. Salt-laden air on the Puget Sound side and Lake Washington side accelerates corrosion on aluminum service entrance components, so we spec copper SE cable and stainless or hot-dipped galvanized hardware on coastal-facing installs in Magnolia, Alki, Madrona, and Seward Park.

Knob-and-Tube Removal & Whole-Home Rewires

Seattle's pre-1950 housing stock — Wallingford, Phinney Ridge, Mount Baker, Madrona, Capitol Hill, Queen Anne, Ballard, the CD — is heavily knob-and-tube. Insurance carriers have effectively stopped writing or renewing policies on K&T-active homes, and the SDCI permit record is what underwriters want to see. We pull the SDCI electrical permit, replace cloth and K&T runs with NM-B 14/2 and 12/2 with ground, install AFCI/CAFCI breakers per current NEC, and provide the inspector-stamped final card that gets the policy reinstated.

ADU & DADU Electrical Wiring

Seattle's ADU/DADU ordinance has produced thousands of new attached and detached accessory dwellings across Greenwood, Beacon Hill, Wallingford, Columbia City, and Rainier Valley. Each one needs either a separate 100-amp service from SCL with its own meter, or a feeder-tapped 100-amp subpanel from the main residence with proper service-disconnect labeling and SDCI-approved load calculations. We design the service to fit the lot — overhead, underground, or trenched from the main house — handle the SCL service application, and complete the rough-in and trim to pass SDCI ADU inspection.

Panel Upgrades, EV Chargers & Surge Protection

Most Seattle 200-amp panel upgrades involve Square D QO or Eaton CH gear with copper bus, AFCI/CAFCI on all bedroom and living-area circuits, and a Type 2 SPD at the service. EV charger installs follow Seattle's permitting workflow — load calc, dedicated 40- or 60-amp circuit, NEMA 14-50 or hardwired Tesla/ChargePoint/Wallbox install, GFCI protection where required by NEC 625, and SDCI inspection. For older homes we frequently use load management devices (DCC-9, Wallbox Power Boost) so a panel upgrade isn't required to add EV charging.
