MAIN 200AWhole House Rewiring in San Ramon, CA
Insurers across Contra Costa County have grown strict about knob and tube and aluminum branch wiring, and some will not write a policy at all. Rewiring a San Ramon home resolves that, and it is the only fix that actually addresses insulation that has gone brittle.

Situations we see in San Ramon
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 Contra Costa County increasingly require removal. We document what was replaced so you have something to send the underwriter.

Reviews from Contra Costa County
Six recessed lights in the living room and a dimmer that finally doesn't buzz. They laid the whole layout out on the ceiling with tape first, which I appreciated.

How much does whole house rewiring cost in San Ramon?
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 San Ramon?
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.
Can I stay in the house during a rewire?
In most San Ramon projects, yes. We work in phases and leave you with power in the rooms we are not touching that day.
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.
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.
