Questions Before You Book
Is a repair visit the same as an installation estimate?
Diagnosing an existing electrical problem is a service appointment. Planned installation work can be discussed through an estimate. Ask our office about the appropriate visit and any applicable charges.
Does an EV charger require a new electrical panel?
Not always. Existing capacity, panel condition, equipment compatibility and available load-management options determine the plan.
What affects electrical project cost?
Equipment, circuit requirements, wiring access, permits and the extent of the work affect the scope and price. Ask which materials and any finish repairs are included.
