Whole Home Rewire
A whole-home rewire replaces or updates electrical wiring throughout the property when existing systems no longer support your electrical needs. Deciding to rewire a house depends on the condition of current wiring, safety concerns, and the extent of any planned renovations.
- Widespread outdated or damaged wiring limits your electrical use.
- Major home renovations leave walls open and accessible.
- Multiple rooms require new branch circuits and outlets.
- The existing circuit layout no longer supports the home safely.
- Electrical modifications have accumulated unsafely over time.
- A targeted repair is not sufficient for the identified scope.
What a Whole-Home Rewire Can Include
Depending on the project, house rewiring involves replacing branch circuits, updating device layouts, and coordinating with existing infrastructure to modernize the system safely.
System Assessment & Planning
Evaluating existing circuits, determining load requirements, and planning new routes to ensure the updated layout safely meets the home's power demands.
Removal of Old Wiring
Safely disconnecting and removing or properly abandoning outdated or damaged wiring according to the specific project scope and code requirements.
Rough-In Installation
Running new branch-circuit wiring, setting electrical boxes, and establishing the foundational pathways while walls are open or accessible.
Upgrading Outlets & Switches
Installing new receptacles, switches, and lighting circuits to support modern appliances, improve convenience, and ensure proper grounding.
Panel Coordination
Integrating new circuits into the existing electrical panel or preparing the system for a capacity upgrade if the current setup is insufficient.
Trim-Out & Testing
Connecting all final devices, verifying proper operation, and coordinating required inspections to ensure the new system is fully functional.
Whole-House Rewiring vs Partial Rewiring
Choosing between full and partial rewiring depends on whether electrical problems or remodeling plans are limited to specific rooms or affect the entire property.
Whole-Home Rewire
Typical project use case
Broad replacement or redesign
Electrical system impact
Updates the entire house
Renovation context
Major remodels with open walls
Partial Rewiring
Typical project use case
Limited to selected rooms
Electrical system impact
Updates targeted circuits only
Renovation context
Kitchen or basement updates
A targeted repair may also be an option when a specific defect can be corrected without broader circuit replacement.
The right approach is determined by an on-site assessment of your existing wiring.
How a Whole Home Rewire Project Works
We approach extensive rewiring methodically, ensuring clear communication, safety, and minimal unnecessary disruption from assessment to final inspection.
- Assess the Existing Electrical SystemA rewiring electrician evaluates current wiring, panel capacity, and overall home condition to determine the project scope.
- Define the New Circuit and Device PlanWe map out new outlets, switches, and lighting circuits based on your load requirements to ensure a functional, code-compliant layout.
- Confirm Access and Project PhasingWe establish how walls will be accessed and determine if work can be safely staged while the home remains partially occupied.
- Install New Wiring and ComponentsThe team routes new branch-circuit wiring, sets electrical boxes, and coordinates any necessary panel or grounding updates.
- Complete Trim-Out and Final TestingWe install all final electrical devices, verify system safety through rigorous testing, and coordinate required inspections.
When Might a House Need Extensive Rewiring?
A complete home rewiring project is typically considered when isolated repairs can no longer address systemic issues or major structural changes are planned.
Widespread Outdated Wiring
Older homes often feature legacy systems that lack proper grounding or cannot safely support modern electrical loads across multiple rooms.

How Much Does It Cost to Rewire a House?

Home Size and Accessibility
The total square footage, number of stories, and access to attics or crawlspaces directly impact how wiring is routed throughout the home.
Occupied vs. Open Renovation
Working in a finished, occupied home requires careful phasing and targeted wall access, while an open-wall remodel streamlines installation.
Circuit and Device Count
The total number of new receptacles, switches, lighting fixtures, and dedicated appliance circuits dictates the overall material and labor scope.
Panel and Service Requirements
Adding modern electrical loads may require updating the main electrical panel or coordinating a service upgrade with the local utility provider.

Whole Home Rewire FAQ
Common questions about planning, execution, and what to expect when updating your home's electrical infrastructure.
To rewire a house means replacing outdated or damaged electrical wiring, boxes, and devices throughout the property.
This process modernizes the electrical system to improve safety, grounding, and overall capacity for modern appliances.
An on-site assessment is required to determine the condition of your wiring.
Broad indicators often include ungrounded outlets, frequently tripping breakers, scorched receptacles, or discovering legacy systems that require knob-and-tube wiring replacement during a renovation.
Whole house rewiring typically involves routing new branch circuits, installing modern outlets and switches, updating lighting, and ensuring proper grounding.
Depending on the existing equipment, it may also require panel coordination.
Yes, partial rewiring is possible when the electrical problems or renovation plans are limited to specific areas.
If the scope can be safely isolated, such as during a kitchen remodel, a complete rewire may not be necessary.
Yes, home rewiring requires access to wall cavities to run new circuits and install electrical boxes.
The extent of drywall removal depends on the home's construction, attic or crawlspace access, and whether the project is part of an open-wall remodel.
It may be possible, but it depends on the project's phasing, safety requirements, and wall access.
Working in an occupied home requires careful staging to ensure critical power remains active and living spaces stay safe.
Not automatically. The panel and electrical service are evaluated separately from the wiring.
If your current panel is in good condition and has sufficient capacity for the new circuit plan, a panel replacement may not be needed.
The timeline depends on the size of the home, the complexity of the circuit layout, and how accessible the walls are.
An open-wall renovation moves faster than phasing work room-by-room in a finished, occupied house.
The cost for house rewiring depends on the home's square footage, the total number of new circuits and devices, and wall accessibility.
Factors like drywall patching responsibilities and required permit fees also influence the final project scope.
