Knob & Tube and Aluminum Wiring Replacement in Mariposa, CA
Knob and tube wiring was state of the art a century ago, and aluminum branch wiring was a cost-saving shortcut in the 1960s and 70s. Both are common in older Mariposa neighborhoods, and both create real fire risk as connections loosen and insulation crumbles. Unique Electrical Services replaces knob and tube and aluminum wiring in Mariposa, CA with grounded copper.
Knob & Tube and Aluminum Wiring Replacement services we provide in Mariposa

Every project in Mariposa starts with a thorough inspection of accessible attic, crawlspace and wall wiring. We document what is active, what is abandoned, and where connections show heat damage. From there we build a phased plan that replaces the risky wiring first and keeps your family's routine intact.
Aluminum wiring does not always require full replacement. In many Mariposa homes, correctly installed connectors at every device and junction bring the system to a safe condition at lower cost. We explain both routes honestly. Homeowners in Midpines, Catheys Valley and Ahwahnee and across Mariposa County have relied on that straight advice.
