OSB dispatches across Tyngsboro, its neighbourhoods and the surrounding Massachusetts towns.
The things we treat as non-negotiable on every Tyngsboro job.
Flat pricing quoted before the work starts. Same-day and next-day slots available across Massachusetts.
“The quote they gave me on the phone was the number on the invoice. That is apparently rare and it shouldn't be.”
“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.”
“They rewired our restaurant kitchen overnight so we never closed a single service. That mattered more than the price, honestly.”
Most Tyngsboro 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.
