Londonderry homes

Londonderry is mostly a town of single-family homes: lots of colonials, capes, and split-levels from the town’s growth decades, newer subdivisions, and homes on larger lots in the more rural parts of town. That shapes the electrical work we do here:

• Service and panel upgrades. Homes from the growth decades often still have their original panels and services, sized long before central air, heat pumps, EV chargers, and finished basements. We upgrade panels and services from 100A through 400A, and retire Federal Pacific, Zinsco, and Pushmatic panels.
• Standby generators. On larger lots and wooded roads, storm outages can last a while, and many homes rely on well pumps. A Generac or Kohler whole-home standby generator (14kW–26kW) with an automatic transfer switch keeps everything running.
• Finished basements and additions. New circuits, lighting, smoke detectors, and panel relocations as part of a basement project.
• Exterior and landscape lighting. Driveway, walkway, and yard lighting for homes on bigger lots.
• EV chargers and heat pumps. Dedicated circuits, done right after a load check.
• New construction. Full electrical scope for new homes, from service entrance through rough-in and trim-out, as the electrical sub for local GCs.

Frequently asked questions

How quickly can you get to Londonderry?

We’re based in neighboring Hudson, so Londonderry is close by. Call and we’ll set a time.

Should I get a generator or an interlock?

A standby generator is automatic and covers the whole house. An interlock is a lower-cost way to use a portable generator. We’ll go over both.

Do you wire new homes?

Yes. We handle the full electrical scope on new construction, often as the sub for local general contractors.

Can you wire my basement after the framing?

Yes. That’s a common job, sometimes together with a panel relocation.
