Portland's Trusted Full-Service Electrical Contractor
Casco Bay Electric is a full-service electrical contractor serving Portland, Maine, and the surrounding Southern Maine region, handling everything from residential panel upgrades and EV charger installations to large-scale commercial and industrial projects. Portland's aging housing stock — Victorians on Munjoy Hill, century-old multi-family buildings in the West End, and Bayside's industrial conversions — creates constant demand for electrical work that requires expertise, not just a licensed handyman with a van.
With offices in Portland, Lewiston, Arundel, and York, and master electricians overseeing every job, Casco Bay Electric is built to handle the full range of what this city needs — from a service call at a historic home on Congress Street to a complete electrical build-out for a hotel or school.
Types of Electrical Services We Provide
Residential Electrical Services
Portland's older neighborhoods present electrical challenges that newer construction rarely does. Knob-and-tube wiring, undersized 100-amp panels, and outdated fuse boxes are common in the West End's Victorian homes and Munjoy Hill's triple-deckers. We handle panel upgrades to 200-amp service, whole-home rewiring, EV charger installations, kitchen and bathroom remodel circuits, and 24/7 emergency electrical repairs. Whether you're a homeowner on Brighton Avenue or a property manager overseeing a multi-family building near the University of Southern Maine, the crew that works high-end custom builds also handles your service call.
Commercial Electrical Services
Portland's commercial corridor — from the Old Port's restaurants and hotels to the healthcare and biotech facilities anchoring the Maine Medical Center campus — demands an electrical contractor who can work around operational schedules, pull proper permits, and deliver without delays. Casco Bay Electric provides commercial wiring, lighting retrofits, panel replacements, generator installations, and full electrical build-outs for new construction. We maintain a 40–50 new-lead weekly volume, staff fully equipped offices with estimators, and mobilize quickly for last-minute contracts — a capability most single-crew shops simply can't match.
Industrial and Institutional Electrical Services
Schools, hotels, marinas, and manufacturing facilities require a different level of coordination than a standard residential job. Casco Bay Electric brings owned equipment — bucket trucks, an excavator, thermal imaging cameras, and underground fault locating tools — so nothing gets subcontracted and no scheduling gaps appear mid-project. Existing institutional relationships include utility work with Unitil and ongoing contracts at industrial facilities. For general contractors managing multi-million-dollar projects in Portland, this is the electrical partner that shows up fully equipped and stays through project completion.
Why Portland Chooses Casco Bay Electric
Maine-Licensed Master Electricians
Every job is overseen by a licensed Maine master electrician, with journeyman work held to that standard throughout — no unlicensed crews cutting corners.
Decades of Regional Experience
Casco Bay Electric has been part of Portland's building community long enough to understand local permitting, coastal construction conditions, and the specific demands of the city's historic housing stock.
24/7 Emergency Response
A rotating on-call electrician is available around the clock, every day — not a voicemail box, but a real person who can dispatch immediately when something fails at 2 a.m.
Owned Specialty Equipment
Bucket trucks, an excavator, thermal imaging cameras, and fault-locating tools are owned outright. Jobs don't stall waiting on a subcontractor's availability.
Trusted by Top-Tier Builders
Portland's leading general contractors and luxury home builders bring Casco Bay Electric onto their largest projects. That same team handles residential and small commercial work.
Local Offices, Real People Answering
Fully staffed offices mean an estimator picks up when you call — no national call center, no callback queue, no delay getting your job moving.
