Why Whole-Home Rewiring is Essential for Safety and Efficiency
Outdated wiring isn’t just inconvenient — it can be dangerous. According to the National Fire Protection Association (NFPA), electrical failures or malfunctions are the second leading cause of U.S. home fires (2022). Homes built more than 30 years ago may not meet modern electrical demands, leading to:
- Frequent breaker trips or blown fuses
- Flickering or dimming lights
- Burning odors from outlets or switches
- Ungrounded or knob-and-tube wiring
- Insufficient capacity for new appliances and technologies
At McCarthy Electric, we provide comprehensive assessments to determine if your home is due for a rewiring project. Our licensed electricians near you will design a safe and efficient electrical system that supports today’s high-demand devices while ensuring compliance with current codes.

Benefits of Whole-Home Rewiring
- Improved Safety: Reduce risks of electrical fires and shocks.
- Enhanced Energy Efficiency: Modern wiring supports energy-saving appliances and systems.
- Increased Property Value: Updated electrical systems are a major selling point.
- Reliability: Avoid interruptions and enjoy consistent power.
- Smart Home Integration: Support for smart devices and EV charging solutions.
Why Not Wait?
Delaying necessary rewiring can lead to significant issues, including potential insurance denial after an electrical fire. Having an up-to-date electrical system is often a requirement for property resale and refinancing.

Rewiring for Remodels and Additions
Whole-home rewiring is especially common during remodeling projects, when walls are already opened up and electrical systems are being upgraded to meet new demands.
Kitchen and Bathroom Remodels
Kitchens and bathrooms place a high demand on your electrical system. From GFCI outlets to dedicated appliance circuits, rewiring during a remodel ensures:
- Properly sized circuits for ovens, refrigerators, and microwaves
- Safe, moisture-resistant outlets and switches
- Stylish and functional lighting, including under-cabinet and vanity lighting
Home Additions and Expansions
If you’re adding square footage, rewiring ensures your new space integrates seamlessly with the rest of your home. This includes:
- Dedicated circuits for HVAC and other appliances
- Smart home features and networking capabilities
- Seamless power distribution to new rooms
By addressing your wiring needs during a remodel, you reduce costs and prevent future headaches.
