Does my Derry home need an electrical permit for repairs or upgrades?

In Derry, virtually any electrical work requires a permit pulled by a licensed New Hampshire master electrician before work begins. The Town of Derry Code Enforcement/Building Department handles permit applications online, and inspections are typically scheduled the next business day. Skipping a permit puts your homeowner's insurance at risk and flags the work during a home sale inspection. Mr. Electric of Southeast NH handles the permit process start to finish, so you don't have to chase paperwork or coordinate with the building department yourself.

My Derry home was built in the 1960s or 1970s — should I be concerned about aluminum wiring?

Aluminum branch circuit wiring was common in homes built between the mid-1960s and late 1970s, and many Derry properties from that era still have it. The most common issue is loose connections: aluminum expands when heated and contracts when cooled, and that repeated movement weakens contact points at outlets, switches, fixtures, and the panel over time. Loose connections create hot spots that damage insulation before you notice any visible signs. A licensed electrician uses a thermal imaging camera and a physical inspection of connection points to find problem areas. If your home has aluminum wiring, schedule an electrical safety inspection before any renovation work — adding circuits to an existing aluminum system without the correct connectors creates additional hazards.

How many amps does my Derry home need?

Most homes built before 1980 have 100-amp panels that are undersized for modern use. A single Level 2 EV charger draws 40 to 50 amps on its own. Add a heat pump, central air, and modern kitchen appliances, and a 100-amp panel runs out of capacity fast. Most electricians recommend 200-amp service as a baseline for modern Derry homes. A service upgrade requires coordinating with Eversource for a temporary disconnect, pulling a permit with the town, and passing a final inspection before power is restored.
