About this service
Copper is the industry standard for home wiring because it conducts electricity efficiently and resists corrosion. Most homes are built with copper, but older properties might have outdated wiring materials. If you notice persistent flickering lights or burning smells near your outlets, you might have aging or damaged copper wiring. An electrician can evaluate your system to ensure all connections are tight and that your copper wiring is properly sized for your current electrical load.
