Whole-House Rewiring in Berkeley
New wiring behind the walls of an older home.
Rewiring older East Bay homes
Many Berkeley and Oakland homes still have their original wiring: knob-and-tube, ungrounded circuits or too few circuits for how a family lives today. Rewiring replaces it with new, grounded circuits run back to your panel.
We rewire whole houses or one room at a time. Where we can, we fish new wire through the crawlspace and attic, so a finished room, even one with custom paint, can be rewired with no damage to the walls. During a remodel, with the walls open, we rewire everything at once.

Rewiring questions
Do you have to open up my walls?
Not always. In many homes we can run new wire through the crawlspace and attic. One of our recent bedroom rewires, in a room with custom paint, was done with no wall damage.
How do I know if my home needs rewiring?
Knob-and-tube or ungrounded two-prong outlets, frequent tripped breakers, flickering lights or a home that hasn't been rewired in decades are all reasons to have it checked.
Can you rewire during a remodel?
Yes. With the walls open it's the best time to replace old wiring and add the circuits you'll need.
