Aluminum wiring installed in homes from the 1960s and 1970s is a documented fire hazard. Replacing it with modern copper wiring dramatically reduces your risk and may lower your insurance premiums.
Our electricians diagnose the root cause of the problem, explain the repair before starting, fix the issue with commercial-grade materials, and test the circuit to confirm a lasting solution.
We review your project requirements, pull necessary permits, install wiring and devices using commercial-grade materials, and schedule the final inspection to close out the permit properly.
