Electrical Expertise for Projects of Every Scope

Casco Bay Electric has grown into one of Southern Maine's most trusted electrical contractors by doing what many regional shops can't: showing up for every type of job without compromising on quality or speed. From the historic Victorian-era homes in Portland's West End — where knob-and-tube wiring and undersized panels are still common — to new construction projects alongside the region's top general contractors, the company operates as a full-service electrical partner rather than a narrowly focused trade shop.

That commitment means clients never need to find a second electrician when a project changes scope. Whether the work is a service upgrade, a tenant build-out, or an emergency call in the middle of the night, Casco Bay Electric's team is equipped and ready.

Types of Electrical Services We Provide

Residential Electrical Services

Portland's older housing stock creates a specific set of electrical demands. Homes throughout the West End, Deering Center, and Munjoy Hill frequently require panel upgrades from 100-amp to 200-amp service to support modern appliances, EV chargers, and updated HVAC systems. Casco Bay Electric handles the full scope of residential work — from rewiring projects in century-old Victorians and multi-family conversions to new construction for high-end custom homes. Every residential job is managed by licensed electricians who understand Maine's permitting requirements and the realities of working in older structures.

Commercial Electrical Services

Hotels, schools, medical facilities, and retail developments throughout Greater Portland rely on electrical contractors who can handle both the planning phase and the execution without handoffs or delays. Casco Bay Electric works directly with general contractors and project owners on commercial build-outs, tenant improvements, and complex infrastructure upgrades. The company owns its specialized equipment — including bucket trucks and thermal imaging cameras — so commercial jobs move on schedule without waiting on outside subcontractors.

Industrial and Contract Electrical Work

Manufacturing plants, marinas, and institutional campuses have electrical needs that go beyond what a typical residential-focused shop is built to handle. Casco Bay Electric's industrial division manages high-demand environments where downtime is costly and precision matters. The team brings in-house underground fault-locating equipment and excavation capability, which means underground infrastructure work stays within a single, accountable crew rather than getting split across multiple vendors.

Why Portland Chooses Casco Bay Electric

Licensed at Every Level

All work is performed by or under the direct supervision of master electricians, fully licensed in Maine. Journeyman electricians operate within that oversight structure on every job — residential, commercial, or industrial.

A Real Person Answers the Phone

Fully staffed local offices with a dedicated estimator mean callers reach someone who can actually move on a project — not a voicemail box or a scheduling queue that stretches into next week.

Volume That Proves Capacity

Handling 100–130 jobs per week across Southern Maine isn't a boast — it's proof that the company's logistics, staffing, and systems are built to scale without dropping the ball on any individual client.

Deep Residential Expertise

Decades of work in Portland's older housing stock — knob-and-tube replacements, service upgrades, and rewires in tight Victorian-era layouts — means fewer surprises and faster completions on homes that require real diagnostic skill.

Commercial Capability, In-House

Bucket trucks, excavators, lifts, and thermal imaging cameras are owned and operated by Casco Bay Electric's own crew. No subcontractors, no scheduling gaps, no accountability gaps when something needs to change mid-project.

24/7 Emergency Response

A rotating on-call electrician covers nights, weekends, and holidays. When a power issue threatens a hotel's operations or a manufacturer's production line, response isn't contingent on someone deciding to pick up a call.
