The things we treat as non-negotiable on every Petersham job.
Flat pricing quoted before the work starts. Same-day and next-day slots available across Massachusetts.
“Storm took out our power for four days last winter. This year we have a standby generator that started itself while we were asleep.”
“Whole-house LED retrofit across our warehouse. Our lighting bill dropped and you can finally read labels on the top rack.”
“Every smart switch I bought failed because there was no neutral. They pulled neutrals in the rooms that needed it and set up the rest properly.”
Most Petersham 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 Petersham 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.
