Electrician in Renton, WA
Our licensed electricians install EV chargers, upgrade panels and services, add circuits, install generators and fix electrical problems in Renton homes. They are dispatched from our Redmond branch; call (425) 645-0404 or use the form to book.
One detail sets Renton apart from most nearby cities: it is one of the Washington cities that issue their own electrical permits and do their own inspections, instead of Washington L&I (L&I, cities that do their own electrical permits). Renton handles electrical, mechanical and plumbing permits through its online permitting portal (City of Renton, permit services). We apply for the city permit, schedule the city electrical inspection, and meet the inspector.

Older homes, older wiring
Renton has homes from nearly every decade since its coal-town beginnings. The older the house, the more likely we are to find:
- Fuse boxes or early breaker panels with limited capacity.
- Ungrounded two-wire circuits, sometimes with three-prong outlets added without a ground.
- Knob-and-tube wiring in the oldest homes, often partly abandoned and partly still live.
- Kitchens and baths without GFCI protection.
- Additions and garages fed from undersized circuits.
We test and document what we find, separate genuine hazards from items that can wait, and price each, so you can plan upgrades in stages.
Service and panel upgrades
Adding an EV charger, heat pump, induction range or hot tub often pushes an older 60, 100 or 125-amp service past its limit. A load calculation shows whether you truly need a larger service, or whether load management or a subpanel will do. When an upgrade is needed, we coordinate the utility disconnect and reconnect, install the new panel and meter base, label every circuit, and pass the City of Renton inspection.
EV charging for I-405 and SR 167 commuters
Renton sits where I-405, SR 167, SR 169 and SR 900 meet, so many residents commute by car every day. A Level 2 charger on a dedicated 240-volt circuit covers a typical day’s driving overnight. We size the circuit to the charger, choose a location where the cable reaches comfortably, and use load management if the panel is close to capacity. Two-EV households can often share one circuit with a power-sharing charger. Chargers with scheduling let you charge overnight, and detached garages or long runs get a conduit route planned and priced up front.
Backup power
Wind storms bring trees down on lines across the Renton hills. If an outage means no heat, no sump pump or no refrigeration, backup power is worth planning. Options include a standby generator with an automatic transfer switch, a generator inlet and interlock for a portable unit, and battery backup for a sump pump. Never plug a generator into a household outlet; backfeeding can endanger utility crews and damage equipment.
Circuits for heat pumps and rebated equipment
If PSE is your utility, it pays $1,500, plus up to $2,400 through Efficiency Boost, when a heat pump replaces electric resistance heat, and $1,000 (or $1,100 with Efficiency Boost) for a heat pump water heater (PSE electric resistance to heat pump rebate; PSE heat pump water heater rebate). Each needs a dedicated circuit, and a heat pump needs an outdoor disconnect. Our electricians handle that wiring as part of the same install, so the equipment, wiring, permits and rebate paperwork move together.

Why the city permit matters
Because Renton inspects its own electrical work, permits and inspections run through the same city system as building, mechanical and plumbing permits (City of Renton, permit services). For projects that involve several trades, such as a heat pump that needs a new circuit, or a remodel with new plumbing and wiring, keeping everything under one city process makes scheduling simpler. It also means that when you sell, the permit history for the work is in one place. Unpermitted electrical work, on the other hand, can surface during a buyer’s inspection and delay a sale or force rework. We permit the work that needs it and leave the final inspection record with you.
ADUs, remodels and additions
Renton offers a permit-ready ADU program (City of Renton, permit services), and backyard units, basement conversions and additions are common projects. Electrically, they raise the same questions every time: can the existing service carry the new load, should the ADU have its own subpanel or a separate meter, and how will the feeder reach it. We work those out with you and your builder early, run the load calculation, and wire the space to current code with GFCI and AFCI protection where required. For kitchen and bath remodels, we plan dedicated appliance circuits and lighting so walls are opened only once.
Pre-sale and pre-purchase inspections
Renton’s housing turns over steadily, and electrical issues are a common item in buyers’ inspection reports. An electrical inspection before you list lets you fix problems on your own schedule and price, rather than negotiating them later. For buyers, it turns vague report language into a clear, priced list. Our electrician checks the service and panel, breaker and wire sizing, double-tapped breakers, missing covers and knockouts, GFCI and AFCI protection, alarms, and any amateur additions, and writes up the findings with prices. Many common items, such as a missing GFCI or a loose cover, are quick fixes that can often be done during the same visit.
Lighting and smart controls
Lighting updates change how a home feels with little disruption: recessed and under-cabinet lighting, new fixtures and fans, dimmers, and smart switches that can schedule exterior lights. LED retrofits cut lighting load, which can free capacity on a crowded older panel. Smart breakers and panel monitors show which circuits use the most power, a useful step before planning a heat pump, EV charger or generator.
Booking an electrician
Tell us what is happening or what you plan to add when you call, and send a photo of the panel label if you can. The electrician looks at the panel and the circuits involved, explains what is needed and whether a city permit applies, and gives you a written price before starting. After the job, circuits are labeled, the city inspection is scheduled if required, and you get a short note of anything else worth watching.
Repairs, lighting and safety
- Outlets and switches that are dead, loose, warm or sparking.
- Lights that flicker or circuits that trip again and again.
- GFCI and AFCI protection where code calls for it.
- Interconnected smoke and carbon monoxide alarms.
- Fixture, recessed lighting, ceiling fan and exterior lighting installs.
- Whole-home surge protection at the panel, which protects the electronic controls in furnaces, heat pumps and appliances.

National data puts a typical service visit between $163 and $538, about $351 (Angi, 2026). We give a written price before starting.
Is knob-and-tube wiring safe?
It can be, if undamaged and not buried in insulation, but it has no ground and is often modified. An inspection shows what is live and what should be replaced first.
Do I need a bigger panel for an EV charger?
Not always. A load calculation shows whether load management or a subpanel avoids a service upgrade.
Can you install a standby generator in Renton?
Yes, with an automatic transfer switch, or an inlet and interlock for a portable generator.
Is it safe to backfeed a generator through an outlet?
No. Use a transfer switch or interlock.
