The things we treat as non-negotiable on every South Harwich job.
Flat pricing quoted before the work starts. Same-day and next-day slots available across Massachusetts.
“Two-prong outlets all through a 1920s house. They grounded what could be grounded and GFCI-protected the rest, then labelled everything.”
“Bought an EV and had no idea what my panel could handle. They did the load calculation, told me straight that I had room, and installed the charger two days later.”
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
Most South Harwich service calls are scheduled same-day or next-day, and emergency calls are dispatched around the clock. Call (833) 652-8933 and we'll give you a real arrival window before we hang up.
Yes. The same South Harwich crew that swaps a dead outlet also rewires whole houses, upgrades service panels, and wires new commercial fit-outs. Nothing is too small to book.
