Yes. Even small jobs like replacing an outlet or switch involve working with live wiring, and mistakes can lead to shock, fire, or code violations. Licensed electricians ensure the work is done safely and up to current electrical code.

GFCI (Ground Fault Circuit Interrupter) outlets shut off power automatically if they detect a ground fault, helping prevent electric shock. They're required by code in areas exposed to moisture, like kitchens, bathrooms, garages, and outdoor spaces.

Common signs include flickering or dimming lights, humming or buzzing noises, bulbs that burn out quickly, or lights that are slow to turn on. If you're noticing any of these, a ballast replacement can usually resolve the issue.

In most areas, yes — tamper-resistant receptacles are required in new construction and renovations, especially in homes with children. They look and function like standard outlets but have built-in shutters that block foreign objects.

Only if they're properly rated and installed. Outdoor outlets need weatherproof, in-use covers and GFCI protection to safely handle rain, humidity, and temperature changes year-round.

Most single-outlet or switch installations and replacements take under an hour. More complex jobs — like adding new circuits, upgrading to smart switches, or installing multiple outdoor outlets — may take longer depending on scope.
