What this service does
A well-placed outlet or a dependable switch makes a room easier to live in. Device work ranges from replacing worn receptacles to adding new locations and controls. The circuit behind the device matters as much as the finish you can see.

Common options and scope
Outlet installation and replacement
Add or relocate receptacles, replace loose or damaged devices, and select tamper-resistant, weather-resistant, or USB-equipped receptacles suited to the location and circuit.
GFCI protection
Install or troubleshoot ground-fault protection in applicable wet, outdoor, garage, kitchen, bathroom, and other required locations. The correct configuration depends on downstream wiring and current code.
Switches, dimmers and multi-location control
Replace single-pole, three-way, and four-way controls; add dimmers, occupancy sensors, timers, and smart switches. Confirm lamp compatibility, load type, neutral availability, and box space.
Floor, countertop and specialty outlets
Plan floor boxes, furniture-power locations, recessed television receptacles, and task-area outlets with approved equipment and suitable wiring routes.
Ungrounded and problematic receptacles
Assess two-prong outlets, reversed polarity, missing grounds, loose connections, and overloaded boxes. A three-prong device by itself does not create a grounding path.
What happens during the work
New wiring may require wall access and permits. Share the room layout and the devices you intend to plug in so the location and circuit can be selected together.
Helpful to have ready
A short description, your city or ZIP, and photos of the visible area or equipment. Never remove electrical covers or touch exposed wiring for a photo.
Questions
Can a two-prong outlet simply be changed to three-prong?
Not without evaluating the wiring. A compliant approach may involve adding a grounding path or a permitted GFCI-protected and labeled arrangement; the correct solution depends on the installation.
