Rewiring Old or Outdated Electrical Systems
Replacing or Repairing Knob-and-Tube and Aluminum Wiring
Why Rewiring Is Necessary
Electrical demands have grown dramatically over the years, and older wiring simply wasn’t designed to handle today’s appliances, electronics, and HVAC systems. Knob-and-tube and aluminum wiring—common in homes built before the 1970s—often lack proper grounding and insulation. As a result, they can overheat or degrade, putting the house at risk.
Rewiring not only improves performance but also ensures every connection meets current Washington safety codes. It’s one of the most effective ways to enhance your home’s long-term safety and value.
Knob-and-Tube Wiring – Needs Rewiring
Knob-and-tube wiring was once standard in early 20th-century homes, but it no longer meets today’s safety requirements. The system uses ceramic insulators and open-air routing, leaving conductors exposed to physical wear and heat damage over time.
Because it lacks grounding and insulation suitable for modern use, full replacement is the safest solution. MAD Energy NW rewires these systems with durable, code-approved materials designed for higher electrical loads and enhanced fire protection.
Aluminum Wiring Upgrades
Aluminum wiring was widely used in mid-century construction, but it expands and contracts more than copper, leading to loose connections and potential arcing. Over time, this can cause outlets or switches to overheat.
Our electricians inspect every junction and replace aluminum runs with copper wiring or approved connectors that ensure stable, long-term performance. Each repair is tested for continuity and grounding to confirm proper operation across the circuit.
The Rewiring Process
Rewiring a home involves careful planning and precision. MAD Energy NW begins each project with a full electrical assessment, mapping existing circuits and identifying areas that require replacement or upgrade. We use modern tools to minimize wall openings, complete work safely, and ensure every connection passes inspection.
Our process includes the following:
- Inspecting all wiring types and connection points
- Removing obsolete or hazardous materials
- Installing new, grounded copper wiring
- Verifying circuit protection and breaker compatibility
- Testing all circuits for stability and compliance
Once the rewiring is complete, we confirm that the entire system operates safely under load and adheres to Washington State electrical regulations.
Benefits of a Full Rewire
A professionally completed rewire offers significant advantages, including the following:
- Improved safety and reduced fire risk
- Enhanced capacity for modern appliances and systems
- Stable voltage and reduced flickering
- Increased property value and code compliance
- Peace of mind knowing your wiring is built to current standards
