Situations we see in Portola Valley
Aluminum branch wiring
Aluminum expands and creeps at terminations and runs hot. Depending on scope we either replace the runs or pigtail every connection with approved connectors.
Fabric insulation crumbling
Once the cloth and rubber goes brittle, conductors sit bare inside boxes. There is no repair for that other than new wire.
Two-prong outlets everywhere
No equipment ground means no fault path. Rewiring the branch circuits is the real fix, though GFCI protection is a legitimate interim step in some cases.
Insurance flagged knob and tube
Carriers in San Mateo County increasingly require removal. We document what was replaced so you have something to send the underwriter.

Reviews from San Mateo County
Flickering through the whole house turned out to be a loose neutral at the service. They found it in under an hour when two other companies had shrugged.
Bill T.Troubleshooting · Portola ValleyWarehouse high bay retrofit to LED. Did it over a weekend so we never stopped shipping, and the place is twice as bright.
Greg L.Warehouse lighting · Portola ValleyWe needed a 200 amp panel before our EV charger install. They did the load calculation, pulled the permit, and had the whole thing done and inspected in a week.

Can I stay in the house during a rewire?
In most Portola Valley projects, yes. We work in phases and leave you with power in the rooms we are not touching that day.
Do I need a new panel if I rewire?
Usually. New circuits need somewhere to land, and a rewire is the natural moment to move to a 200 amp panel with AFCI protection.
How much does whole house rewiring cost in Portola Valley?
It scales with square footage, number of circuits, attic and crawlspace access, and whether the walls are plaster or drywall. A 1,200 square foot single story with attic access is a very different number than a two-story plaster home. Call (833) 652-8933 for a walkthrough and a firm scope.
Is knob and tube wiring illegal in Portola Valley?
Existing installations are generally allowed to remain, but you cannot extend them, most insurers dislike them, and the insulation is long past its service life. That combination is why owners replace it.
Will you cut up my walls?
Some openings are unavoidable, but we fish through existing cavities wherever we can and keep openings small, straight and in patchable locations. We tell you where they will go before we cut.
