Commercial Fit-Outs & New Construction
Finlayson Electric is the electrical contractor that general contractors and property managers trust to show up, communicate clearly, and get the job done right — on schedule and to spec.
Commercial electrical work demands a different level of coordination than residential. You’re working to a schedule, alongside other trades, with a general contractor or project manager watching the timeline. The last thing you need is an electrician who doesn’t communicate, falls behind, or leaves problems for someone else to fix.
Finlayson Electric has built its commercial reputation the same way it built its residential one — through honest communication, clean work, and a consistent willingness to go the extra mile. We work directly with general contractors, builders, and property managers across Southern NH and Northern MA on projects of all sizes, from single-tenant fit-outs to full new construction wiring.
When you bring us onto a job, you get a crew that coordinates well with other trades, keeps you informed throughout, and delivers work that passes inspection the first time.
What's Included
Full Commercial Electrical Services.
Commercial Space Fit-Outs
Retail spaces, offices, restaurants, medical suites, and more — we handle all the electrical work for tenant fit-outs from rough-in through trim, coordinating with your GC to stay on schedule and within scope.
New Construction Wiring
From pre-wire through final inspection, we handle the complete electrical scope on new commercial builds — working closely with the project team to hit milestones and keep the job moving.
Large-Scale Electrical Projects
Multi-unit buildings, warehouse conversions, and large commercial projects where precision, coordination, and a crew that shows up reliably makes all the difference.
Panel & Service Upgrades
Upgrading an existing commercial space to handle higher electrical demands? We assess your current service and handle all panel and service upgrades with minimal disruption to operations.
Commercial EV Charger Installation
Installing EV charging stations for a commercial property, parking lot, or fleet operation? We handle the full electrical scope — from load assessment and panel work through final installation and inspection.
Emergency Generator Wiring
Commercial properties that require backup power — medical offices, data centers, food service operations — we install and wire commercial standby generator systems to keep your business running through any outage.
Permits, Inspections & Code Compliance
We handle all permitting and coordinate inspections for every commercial project. All work is completed to current NEC and local code standards — so you're not chasing certificates of occupancy at the end of a job.
Why Contractors & Property Managers Choose Finlayson.
On a commercial job, your electrician’s performance reflects on you. Here’s what you can count on from our crew:
We Communicate
We respond to calls and messages quickly, keep you updated on progress, and flag issues before they become problems. You'll never be chasing us down for a status update.
We Hit Schedules
We know that on a commercial job, one trade running behind holds everyone else up. We show up when we say we will and coordinate with other trades to keep the project moving.
We Pass Inspection
Every job is done to code from the start — not patched up at the end. We coordinate with inspectors and handle all required documentation so you're not scrambling at certificate of occupancy time.
We're Easy to Work With
Approachable, honest, and straightforward. We work with your team, not against it — and we treat every project as a long-term relationship, not a one-time transaction.
