Panel and Service Upgrades in Southern NH and the Merrimack Valley

More capacity from the meter to the panel, and a straight answer on whether you actually need it.

What you get

What a panel upgrade actually involves

A panel upgrade replaces an older or overloaded electrical panel with a modern one that safely carries your home's real load, and a service upgrade brings more power into the house to feed it. If your breakers trip often, you still have a fuse box, or you are adding a generator, EV charger, or hot tub, we will tell you straight whether you need an upgrade and size it right the first time.

Most older homes in southern New Hampshire and the Merrimack Valley were wired for a fraction of what a modern household runs. A right-sized panel gives you clean capacity for today and headroom for the next project, without nuisance trips or hot spots. We check what you actually run before we quote, so you pay for the service your home needs, not a number pulled from a catalog.

  1. Load check and honest estimate

    We look at your current panel, your real usage, and any upgrades you are planning, then give you a clear written number before any work starts.

  2. Permit, upgrade, and inspection

    We pull the permit, coordinate the utility disconnect and reconnect, install the new service, and label every circuit so the panel makes sense at a glance.

  3. Walk-through and clean finish

    You get a walk-through of the finished work, the inspection signed off, and the space left clean, the way we would want it in our own homes.

Service upgrades

Service upgrades, from the meter to the panel

A service upgrade replaces the equipment that brings power into your home: the service mast or underground feed, the meter socket, and the main disconnect, usually to 200 amps. It gives the panel behind it the power to carry what you run today and what you add next.

  • You are adding a big load

    An EV charger, heat pump, hot tub, standby generator, or an addition that your current service cannot carry.

  • The outside equipment is worn

    A rusted or leaning mast, a meter socket pulling away from the siding, or cracked, weathered service cable.

  • Your service is 100 amps or less

    Common in older homes here, and often the real limit behind a crowded panel and nuisance trips.

We pull the permit, coordinate the disconnect and reconnect with your utility, and schedule the inspection, so the power is off for a short, planned window and the day goes the way we told you it would.

How do I know if I need a panel upgrade?

You likely need one if breakers trip often, you still have a fuse box, your panel is a known problem brand, or you are adding a large load like a generator, EV charger, or hot tub. We confirm it with a real load check, and we will tell you honestly if your existing panel is fine.

How long does a panel upgrade take?

A standard residential service upgrade is usually a one-day job, with a short planned power interruption while the new panel is set and the utility reconnects. We give you the expected timing in your estimate so you can plan around it.

Do you handle the permit and inspection?

Yes. We pull the electrical permit, coordinate with the utility, and schedule the inspection, so the upgrade is done to code and signed off. That paperwork also matters if you sell the home later.

Will an upgrade let me add an EV charger or generator later?

That is one of the most common reasons homeowners upgrade. We size the new panel with your planned additions in mind, so adding an EV charger or standby generator down the road is a clean addition rather than a second big project.

What is the difference between a panel upgrade and a service upgrade?

A panel upgrade replaces the breaker panel inside your home. A service upgrade replaces what feeds it: the service mast or underground feed, the meter socket, and the main disconnect, usually along with the panel, so your home can draw more power from the utility, typically 200 amps. We look at both and tell you which one your home actually needs.

Do I have to call the utility for a service upgrade?

No, we handle it. We coordinate the disconnect and reconnect with your utility and the inspection with your town, so all you plan for is a short, scheduled power outage on the day of the work.
