New Construction Electrical
in Southern NH
A.J. LeBlanc Heating's licensed New Hampshire electricians wire new homes from the service entrance and panel through rough-in, devices, and final connections. We work with builders and general contractors on new homes, additions, and accessory dwelling units (ADUs), backed by a family-owned company that has served Southern NH since 1928.

New Construction Electrical FAQ
Do you work with builders and general contractors?
Yes. A.J. LeBlanc Heating takes on new construction electrical alongside your general contractor. We coordinate scheduling, phases, and inspections with the general contractor so the electrical work stays on track with the rest of the build.
Do you handle the electrical permit?
Yes. We pull the electrical permit and coordinate the rough and final inspections with the local Southern NH building department and the utility for the service connection.
What is electrical rough-in on a new home?
Rough-in is the first phase. We set the service entrance, meter, and panel, then install electrical boxes and run wiring through the framing before insulation and drywall. After the walls are closed, we install the devices and fixtures, finish the panel connections, and complete the final inspection.
Can you wire a new home to be EV and heat-pump ready?
Yes. We size the service and panel for the home's planned electrical demand. We can also install circuits and provisions for EV chargers, heat pumps, standby generators, and whole-home surge protection during construction, whether the equipment is going in now or later.
