Like-for-like fan and light swaps on existing wiring

SnapWork swaps old electrical fixtures for new ones on the wiring that is already there: a ceiling light or fan, a wall light, a switch or dimmer, an outlet, a smoke or carbon monoxide alarm, or an outdoor light. You buy the new fixture; a pro licensed for the work installs it in the same box. New circuits, new fixture locations and panel work are not part of it. We work across Napa County and Solano County.

Swap, don't add

Every job on this page replaces something that is already wired in. If there's a light in the ceiling today, a new fan or light can go in its place. If there's nothing there, it's new wiring, and that's a job for an electrician.

Buy the fixture first

Pick the fan or light you want and have it at home. For fans, check the ceiling height and blade size on the box. For dimmers, check that the dimmer works with your bulbs; mismatched bulbs flicker.

Safety first

The pro turns off the breaker before touching any wires. If the wiring behind the old fixture is burned, brittle or aluminum, the pro stops and tells you; that's a repair for an electrician.

What to photograph

  • The fixture you're replacing, and the ceiling or wall around it

Questions people ask

How much does it cost to install a ceiling fan with existing wiring?

A swap on existing wiring is priced from your photo, because the ceiling height and the box decide the work. You see the price before you book.

Can you add a fan where there's no light now?

No. A new fixture location needs new wiring, which is an electrician's job and not a swap.

Will my ceiling box hold a fan?

Fans need a fan-rated box. The pro checks the box before hanging the fan, and if it isn't fan-rated, tells you before going further.

Who does the electrical work?

Electrical swaps go only to a pro who is licensed for the work. The power is turned off at the breaker before anything is disconnected.
