Full & Partial Home Rewiring

Homes with outdated or deteriorating wiring may require a full rewire, while others only need specific areas addressed. We evaluate the existing wiring condition and recommend the appropriate scope, rather than defaulting to a full replacement when it isn't warranted.

 Common reasons for rewiring:

  • Knob-and-tube wiring

  • Aluminum wiring

  • Frequent breaker trips or warm outlets

  • Insufficient circuits for current electrical demand

  • Home additions requiring extended wiring

Knob-and-Tube & Outdated Wiring Replacement

Knob-and-tube and other outdated wiring systems were not designed for modern electrical loads and are frequently flagged during inspections or insurance reviews. We replace these systems with current, code-compliant wiring suited to the home's actual usage.

Kitchen, bathroom, and basement remodels typically require new circuits, relocated outlets, and updated code compliance, including GFCI and AFCI protection where applicable. We coordinate electrical work around the remodel timeline to avoid unnecessary delays.

Home Addition Electrical Work
