Who does gas fitting in NH and MA?

It takes a separate gas license in each state, which is why most plumbers stop at the border. JP Karos holds gas-fitting licensure in NH plus plumbing licenses in MA and ME, so one contractor covers the whole corridor.

Can you run a gas line for my range or generator?

Yes. That's a routine permitted job, usually a single visit after the meter check. You'll get a firm price before work starts.

Do you do restaurant and commercial kitchen gas work?

Yes. Restaurants are one of our named markets, and our food-plant process piping is photographed in the gallery.
