Cornelius' electrician

Cornelius sits in the heart of Washington County's farm country, between Hillsboro's Silicon Forest and Forest Grove's college town. The Tualatin Valley around it grows nursery stock, berries, and hazelnuts — and the town itself is a blend of agricultural roots and suburban growth, with farmhouses from the last century sharing roads with new subdivisions. It's a practical place, and it deserves electrical work done the practical way.

The power comes from Portland General Electric, and the arrangement is the Oregon standard: the utility owns the service to the meter, and everything past it is yours. Pacific Northwest weather keeps that boundary active. Winter windstorms drop limbs on service drops; the occasional ice storm coats everything and takes lines down; and the long rainy season works moisture into every enclosure that isn't sealed properly.

The housing tells two stories at once. The farmhouses and mid-century homes carry the classics: fuse boxes, ungrounded circuits, aluminum branch wiring, and panels sized before the modern household. The new builds go up with 200-amp services, EV-ready garages, and smart panels. And Oregon's ADU-friendly rules mean backyard cottages and converted garages are everywhere — each one needing its own properly wired service.

The agricultural surroundings add their own electrical texture. Nurseries, barns, and outbuildings run wells, pumps, and equipment on long feeders. Moisture is the constant enemy — the valley's rain finds every unsealed box and every compromised connection. We wire farm properties for the wet, not for the brochure.

We do electrical work in Cornelius for the whole valley: farmhouses, subdivisions, ADUs, and barns. Careful assessments, scopes you can actually read, and work built to hold through windstorm season and the long wet winter.

Cornelius sits between two different worlds — Forest Grove's college town to the west, Hillsboro's tech corridor to the east — and the town absorbs both. Professors and engineers live on the same streets as nursery families. The electrical work reflects that mix: ADUs for multigenerational households, home offices needing clean power, and farm properties that still run on well water.

There's a rhythm to the valley's year that shapes our schedule: windstorm season in winter, irrigation season in summer, and the long wet months in between. We plan around it — outdoor work in the drier windows, panel upgrades scheduled at your convenience, and storm response whenever the weather decides.

Why Cornelius calls us

Why the valley chooses us

•We know both eras of housing: Farmhouse knob-and-tube and mid-century aluminum on one street; smart panels and EV chargers on the next. Recognizing the pattern means diagnosing correctly and pricing fairly from the start.
•ADUs wired properly: Backyard cottages and garage conversions need their own load calculations, proper subpanels, and code-compliant everything. We do ADU electrical regularly and know what the inspectors look for.
•Storm damage rebuilt to hold: Windstorms and ice take down entrances here. We rebuild your side of the meter — mast, weatherhead, meter base, panel — and coordinate the PGE reconnect.
•Moisture is our specialty: The valley's rain destroys unsealed electrical. We seal enclosures, use weather-rated gear outdoors, and place equipment with the wet season in mind — because dry electrical is safe electrical.
•Home offices and clean power: Remote work runs on reliable electricity. We add dedicated office circuits, whole-house surge protection, and proper grounding — so the workday never depends on a tired breaker.
•Panel capacity planning: We don't just fix today's problem — we look at where your loads are heading. EV chargers, ADUs, heat pumps, home offices: we size panels and services with the next decade in mind, so you upgrade once.

Electrical trouble we find in Cornelius

Moisture in outdoor equipment

The valley's rain is the number one killer of outdoor electrical — unsealed enclosures, compromised gaskets, and connections that corrode from the inside. We replace the damaged gear with properly sealed, weather-rated equipment and place new installations with the wet season in mind. We also check the grounding electrode system, since wet soil changes grounding behavior and corroded ground rods fail silently.

Windstorm entrance damage

Winter windstorms drop limbs on service drops and tear weatherheads from siding. Post-storm, we check the drop, mast, weatherhead, meter base, and panel — wind damage likes to hide until the following storm. We also inspect the grounding connections afterward — wind movement loosens what the installer tightened.

ADU wiring shortcuts

Backyard cottages and garage conversions get wired informally too often: undersized feeders, no load calculation, subpanels that violate the basics. We wire ADUs properly — load calc, correctly sized feeder, code-compliant subpanel — so the cottage is as safe as the main house. We also verify the ADU's grounding and bonding, since detached cottages are often missing both.

Aluminum branch wiring

Aluminum branch circuits run through the mid-century homes here, and their connections oxidize, work loose with temperature swings, and run hot. We examine each connection and set it right with aluminum-rated connectors or a copper rewire.

Farm outbuilding feeders

Barns, nurseries, and shops run on long feeders that are often undersized, unprotected, and weather-beaten. We size conductors for the actual distance and load, install disconnects at each building, and ground everything properly. We also label every disconnect clearly, since farm properties accumulate buildings and the next owner shouldn't have to guess.

Ice storm damage

The valley's occasional ice storms coat drops and limbs in ice until something gives. We inspect the full entrance path after ice events and harden the installation where the building allows — because the next ice storm is a matter of when, not if.

Fuse boxes in farmhouses

Fuse boxes still serve the oldest farmhouses, layered with generations of improvisations. We replace the box with a modern breaker panel sized for the property's real loads — house, outbuildings, and well equipment together.

Well and irrigation electrical

Wells and irrigation pumps are the lifeblood of valley properties, and their electrical takes punishment from moisture and hard water. We give pumps dedicated circuits, weatherproof disconnects, and generator switchover so a power failure never means no water. We test the pump under load while we're there — a pump struggling electrically is usually a pump about to fail mechanically.

Ungrounded farmhouse outlets

Two-wire circuits with three-prong outlets are standard in the old farmhouses — they look grounded without being grounded. We test each outlet, run true grounds where the wiring allows, and fit GFCI protection where it doesn't. Home offices full of expensive equipment make this more than a technicality — ungrounded outlets can damage what they power.

Panels with no room to grow

Between EV chargers, ADUs, and home offices, the 100-amp panels in older homes are maxed out. We evaluate the panel's remaining capacity honestly: sometimes a managed charger fits, sometimes the house needs the full upgrade to 200 amps.

How your Cornelius project gets done

1

Reach out

Phone (833) 606-5080 or send a message through our site. Tell us what's happening in plain language — and whether it's a house, an ADU, or a farm property, since each gets its own assessment. We'll ask the questions that matter and give you a straight picture of what comes next.

2

On-site assessment

We come out with professional instruments: load metering, thermal imaging of the panel, and a full look at the service entrance from drop to meter base. On farm properties we walk the outbuilding feeders too. What we find shapes the plan. We document conditions with photos, so the scope we write later matches what we actually found.

3

Scope and price in writing

You get a written scope separating urgent safety work from later phases, each priced separately. Nothing starts until you've approved the scope — every phase gets its own go-ahead from you.

4

Permits and PGE

Service work requires permits and a power cut coordinated with PGE. We run the coordination and keep your power-off time short. Filing, scheduling, and inspection follow-through are all ours to manage.

5

Tested and walked through

Every circuit we touched gets load-tested, every protective device verified, and the panel labeled clearly. Then we walk through the finished work with you — findings, fixes, and what's next if anything is.

Client Experience

What to Expect Working With Us

"Windstorm tore our service drop down. They rebuilt the entrance, sealed everything against the rain, and coordinated the PGE reconnect. Knew exactly what valley storms do to electrical."

- Janet

"Our ADU was wired by the previous owner's handyman and it showed. They redid it properly — load calc, new subpanel, everything to code. The inspector passed it without a single correction."

- Paul

"The barn feeder was undersized and the disconnect was rusted through. They ran a proper new feeder, set a real disconnect, and grounded everything. The nursery equipment runs better now."

- Maria

"Fuse box in our 1940s farmhouse and aluminum wiring besides. They replaced the panel, fixed every connection, and phased the work so we could budget it. Straight shooters."

- Dan

"Our 1960s house needed a panel upgrade and the ADU needed its own service. They handled both, coordinated the PGE disconnect once, and everything passed inspection cleanly."

- Rosa

Frequently Asked Questions

Yes — ADU electrical is regular work for us. It starts with a load calculation for the cottage, then a correctly sized feeder and a code-compliant subpanel. We know what Washington County inspectors look for, and we wire it right the first time so the inspection passes clean. For garage conversions we also check the structure's existing wiring first — many were wired as storage, not as living space.
Stay away from anything downed or hanging — storm-damaged entrances can still be live. Leave the mast and meter alone. Reach out; we evaluate your side of the entrance, make hazards safe, record everything for your insurer, then repair and work with PGE on the reconnect. If the damage is widespread, we prioritize hazards first, then work through repairs in the order that restores the most customers fastest. For farm properties we also check the outbuilding feeders, since windstorms rarely damage just one building.
The valley's long wet season finds every weakness — unsealed enclosures, cracked gaskets, connections that were never weather-rated. Moisture corrodes from the inside, and the damage hides until something fails. We use sealed, weather-rated gear outdoors and place it with the rain in mind. Attic and crawlspace penetrations deserve attention too — that's where wind-driven rain enters and travels along cables. Junction boxes in crawlspaces are a common failure point — we replace compromised boxes with sealed ones rated for wet locations.
It's the connections that pose the risk, not the wire itself. Aluminum oxidizes at terminations, loosens as it heats and cools, and overheats. Every connection gets a look and a fix — aluminum-rated connectors where the wire is sound, a copper rewire where it isn't.
It can be fed from the house, but it needs proper infrastructure: a feeder sized for the distance and load, a disconnect at the building, and full grounding. We do this work regularly — the outbuildings get the same standard as the house. For properties with livestock or temperature-sensitive crops, we also discuss backup power — an outage during a freeze can be costly.
They do — permits and inspection are required for panel upgrades and service work, and PGE handles the utility-side coordination. We manage the whole process: filing, disconnect scheduling, and inspection follow-through. The paperwork protects your resale value and keeps your insurer satisfied. ADU electrical work needs its own permits too, separate from the main house — we file both together when the project calls for it.
A generator matched to the pump's starting surge, with transfer switching for a safe handoff. We meter the pump's actual draw, size the generator to match, and prove the switchover under load. On a farm property, no power should never mean no water. We also check the pressure switch and tank settings during the visit, since electrical and plumbing troubles often travel together.
Yes — and size the new service for the whole property, not just the house. The fuse box's improvisations are the real hazard, and the service is undersized for modern loads plus outbuildings and well equipment. We replace it with a modern panel and document everything.
It depends on the whole property: house loads, outbuildings, well pumps, irrigation, EV chargers, and the ADU if you have one. We run a full load calculation across everything, then size the service with room to grow. Guessing is how properties end up with maxed-out panels. Future-proofing matters here: we often recommend sizing up one step, since the next decade tends to add loads nobody planned for.
Usually, yes — it comes down to remaining panel capacity. Our first step is evaluating the panel: a full one might need a smaller managed charger or an upgrade, while 200-amp service usually has space. Your charger is wired to a circuit designed around its demand, and we take care of permits and inspection. For households planning a second EV down the road, we can rough in capacity for it now — cheaper than opening the panel twice.
