Commercial Electrical Work Built for Brooklyn Businesses
Commercial work in Brooklyn means a three-phase 208-volt service shared with the apartments upstairs, a Con Edison vault under the sidewalk and a landlord who wants a certificate of insurance before anyone touches a wire. Our electricians have done it on Fulton Street, on Atlantic Avenue and in the loft buildings off Morgan Avenue.
Restaurant kitchens get dedicated circuits for every piece of equipment, hood and make-up air interlocks, and walk-in coolers on their own feed. Offices get clean power for the server closet, lighting on occupancy sensors and enough receptacles that nobody daisy-chains a power strip. Salons, gyms and medical offices get the same treatment, with the equipment list driving the circuit count.
Every job is filed with the DOB, inspected and signed off, so the certificate of occupancy and the liquor license have what they need.

What Affects the Cost of Commercial Electrical Work in Brooklyn
Service size.
A new three-phase service with Con Ed involvement is the biggest line on most build-outs.
Equipment load.
Fryers, ovens and walk-ins each want a circuit, and the count adds up fast.
Square footage and fixture count.
Lighting and receptacles scale with the floor plate.
Hours.
Occupied spaces get after-hours work, which costs more per hour and less in lost business.
Engineering and permits.
Drawings, filings and inspections are listed on every estimate.
