Planning electrical work in Chelmsford?

Plan before walls close

For a kitchen or basement renovation, decide where you want outlets, lighting controls and dedicated circuits while wiring access is still open.

Check capacity before adding equipment

For an EV charger, heat pump or kitchen remodel, we can assess the existing load and equipment. A panel replacement and an increase in service capacity are different projects.

Should I request a repair visit or an estimate?

For an outlet, light or circuit that isn’t working, ask for a diagnostic visit. For a planned installation or upgrade, ask about an estimate. We explain any applicable visit charges when booking.

Will I need an electrical permit?

Permit and inspection requirements depend on the scope. We’ll review what applies to your project and discuss scheduling or utility coordination when needed.

Does a tripping breaker mean I need a panel upgrade?

Repeated trips can have several causes. We diagnose the fault and consider panel condition, existing demand and any new equipment before recommending options.
