Older Wiring • Modern Circuits • Residential Rewiring
Whole House Rewiring in San Jose & Santa Clara County
If your home still relies on aging or outdated wiring, Dollens Electric can evaluate the existing electrical system and plan a clean, code-compliant rewire around the way your home is built and the electrical demands it needs to support today.

Start With the Wiring That Is Actually in the House
Does Your Home Need a Full Rewire — or Targeted Electrical Work?
Older wiring does not automatically mean every wire in the house has to be replaced. The right scope depends on the wiring type, its condition, how circuits have been modified over the years, grounding, breaker protection, current electrical demand and what you are planning next.
Dollens Electric evaluates the existing system first. If targeted circuit work makes sense, we explain that. If the house has widespread outdated wiring or a remodel makes full replacement practical, we build the rewire around a clear plan.
When an Electrical Evaluation Makes Sense
Signs the Wiring Deserves a Closer Look
These conditions can have several causes. They are reasons to investigate the electrical system, not a diagnosis by themselves.
Older Bay Area Wiring
The Wiring Type Helps Determine the Right Rewire Strategy
Different legacy wiring systems create different inspection, access and replacement considerations.
Knob-and-Tube Wiring
Knob-and-tube systems can still be found in older Bay Area homes. We evaluate where it remains, how it has been altered, circuit condition, grounding needs and how replacement can be routed.
Cloth-Insulated Wiring
Older cloth-covered cable can deteriorate with age and may coexist with decades of additions and repairs. The condition of the insulation, connections and circuit layout matters.
Aluminum Wiring
Aluminum branch wiring requires careful evaluation of the conductors, terminations and devices. Depending on the house and project goals, the recommendation may involve correction or replacement.
Careful Work in Finished Homes
A Rewire Should Not Mean Needlessly Opening Every Wall.
Rewiring a finished home requires planning before anyone starts cutting access holes. Attics, crawlspaces, closets, existing device locations and remodel areas can all affect how new circuits are routed.
Dollens Electric plans the electrical routes around the construction of the home and works to limit unnecessary wall and ceiling damage while still providing the access required for safe, code-compliant work.
Access is planned around the house — not improvised room by room.
Project Scope
What a Whole-House Rewire Can Include
The exact scope is designed around the home's existing system, layout and planned electrical needs.
Branch Circuit Replacement
Replacement of outdated or unsuitable branch wiring with properly sized modern conductors and circuit protection.
Grounded Receptacle Circuits
Modern grounded circuits and receptacle locations planned around how the home is actually used.
Lighting Circuits
New lighting wiring, switch locations and related circuit work, including recessed lighting when part of the project.
Dedicated Circuits
Dedicated circuits for appliances and equipment where the load or current requirements call for them.
Panel Coordination
Review of breaker space, service capacity and whether the existing panel can support the completed rewire.
Required Protection
Appropriate GFCI, AFCI and other protection based on the circuits, locations and permitted scope.
Permits & Inspection
Permit and inspection coordination when required for the rewiring scope and local jurisdiction.
Testing & Labeling
Final testing, verification and circuit labeling so the completed electrical system is understandable and serviceable.
How the Project Moves Forward
Our Whole-House Rewiring Process
A good rewire begins with a plan for the electrical system and the building before installation starts.
Evaluate
We inspect accessible wiring, panels, circuits and devices, then discuss symptoms, remodel plans and future electrical loads.
Design the Scope
We determine what should be replaced, what can remain, where new circuits should go and how access can be handled.
Rewire
New circuits are routed and installed, with outdated wiring removed or taken out of service as appropriate to the approved scope.
Test & Inspect
Circuits are tested and labeled, and required inspection steps are completed before the project is closed out.
Rewiring and the Main Panel
A Whole-House Rewire Does Not Automatically Mean a Larger Electrical Service.
Rewiring changes the branch circuits throughout the home. A panel or service upgrade is a separate decision based on panel condition, breaker space, service capacity and the electrical loads the home needs to support.
We evaluate both together so the new wiring is coordinated with the panel without turning a rewiring project into unnecessary service work.

What Affects the Cost of Rewiring a House?
Whole-house rewiring pricing depends heavily on the building, access and electrical scope.
Home Size & Circuit Count
The number of rooms, devices, lighting locations and dedicated circuits directly affects the amount of wiring and labor required.
Access & Construction
Attic and crawlspace access, finished ceilings, multiple stories, plaster, remodel areas and other construction details affect routing and labor.
Existing Electrical Conditions
Panel condition, legacy wiring, prior alterations, grounding needs and related electrical corrections can change the final scope.
Real Dollens Electric Work
Whole-House Rewire & Recessed Lighting — Campbell
This completed Campbell project combined a whole-house electrical rewire with new recessed lighting and wall fixtures, updating the electrical system throughout the living areas.
It is a good example of why rewiring and remodeling are often best planned together: electrical routes, lighting locations and finished-space access can all be coordinated before walls and ceilings are closed.

Projects That Often Connect to Rewiring
These should only be added when they are relevant to the electrical plan for the home.
Why Dollens Electric
Rewiring Requires Electrical Skill and an Understanding of the Building.
Replacing hidden wiring in an occupied or finished home is as much about planning and access as it is about pulling new cable.
C-10 Electrical
Whole-house rewiring is core electrical infrastructure work, from branch circuits and devices to breaker protection and testing.
B General Building
Understanding how the home is built helps with routing, access planning and coordination when electrical work crosses finished spaces.
Evaluate Before Expanding Scope
We separate the wiring work the home needs from unrelated upgrades so the project stays focused on the actual electrical condition.

Whole-House Rewiring in San Jose & Santa Clara County
Dollens Electric works with homeowners throughout San Jose and nearby South Bay communities, including Campbell, Santa Clara, Cupertino, Sunnyvale, Los Gatos, Saratoga, Milpitas, Mountain View and surrounding areas.
Older homes throughout the South Bay can contain several generations of wiring and alterations. Our job is to understand what is actually there before deciding how much of the system should be replaced.
Common Questions
Whole-House Rewiring FAQs
How do I know whether my entire house needs rewiring?
A full rewire should be based on the wiring type, condition, circuit layout, grounding, prior modifications and the home's current electrical needs. An inspection can determine whether the problem is localized or widespread.
Do you replace knob-and-tube wiring?
Yes. Dollens Electric evaluates existing knob-and-tube systems and can replace or take outdated circuits out of service as part of an approved rewiring scope.
What about cloth-insulated wiring?
Cloth-covered wiring can deteriorate with age and may have been altered many times over the life of the home. We evaluate the condition and circuit layout before determining whether targeted work or broader replacement is appropriate.
Does aluminum wiring always require a full-house rewire?
Not automatically. The recommendation depends on where aluminum branch wiring exists, the condition of the conductors and connections, prior repairs and the goals of the project.
Will rewiring destroy my walls and ceilings?
Rewiring a finished home requires access, but careful routing through attics, crawlspaces, closets and existing device locations can reduce unnecessary openings. The access plan depends on how the house is built.
Should I rewire while remodeling?
A remodel can be an efficient time to address old wiring because walls or ceilings may already be open. It also allows new circuits, receptacles, lighting and future electrical loads to be planned together.
Does a whole-house rewire require a new electrical panel?
Not necessarily. The panel is evaluated separately for condition, breaker space and service capacity. It should only be replaced or enlarged when the existing equipment or load requirements justify it.
Do you handle permits and inspections for rewiring?
Dollens Electric coordinates applicable electrical permit and inspection requirements as part of the approved rewiring project.
