Know what is in the walls
Knob-and-tube wiring should be assessed before it is covered, altered or relied on for new loads.
Older wiring may be part of a larger electrical system that has changed over time. An assessment helps identify where knob-and-tube wiring remains, what has been modified and which upgrade path makes sense for the home.
Electrical assessment
Review of visible wiring, accessible areas, devices, panels and the home's current electrical condition.
Partial rewiring
Targeted replacement of knob-and-tube wiring in renovated rooms, problem areas or locations where new circuits are needed.
Full-home rewiring
Replacement planning for a complete electrical system, including grounded branch circuits, devices and panel coordination.
Renovation coordination
Electrical rewiring planned alongside walls being opened, insulation work, kitchens, bathrooms, additions and other renovations.

Questions & answers
Common questions about knob-and-tube rewiring
An on-site assessment is the best way to confirm what wiring remains and what work the home actually needs.
Does every older home need a full rewire?
Not necessarily. The right scope depends on where knob-and-tube wiring remains, its condition, later modifications and the home's planned use. An assessment comes first.
Can you rewire only one room?
Often, yes. Partial or staged rewiring can be planned for a renovation, a problem area or a room that needs new grounded circuits.
Will rewiring help with insurance questions?
It can provide a clearer electrical condition and upgrade plan, but insurance requirements vary. Confirm the insurer's specific requirements before work begins.
Can you work while the walls are open?
Yes. Renovations are often a practical time to replace older wiring, add circuits and install new devices before insulation and drywall.
Does rewiring include a panel upgrade?
It may, depending on the condition and capacity of the existing panel and the electrical loads planned for the home. Panel work is reviewed as part of the scope.
What should I send to request a quote?
Send the home's age, photos of the panel and accessible wiring, the reason for the assessment and any renovation or insurance requirements.
