Signs Your Home Needs Rewiring

- ⚠Aluminum wiring — Common in 1960s-70s homes. Aluminum expands and contracts, loosening connections and creating fire hazards at outlets and switches.
- ⚠Knob-and-tube wiring — Found in pre-1950s homes. No ground wire, deteriorating insulation, and incompatible with modern loads.
- ⚠Frequently tripping breakers — Indicates circuits are overloaded beyond their safe capacity.
- ⚠Two-prong (ungrounded) outlets — No ground wire means no protection against electrical faults.
- ⚠Warm or discolored outlets — Indicates loose connections or arcing behind the wall.
- ⚠Federal Pacific or Zinsco panel — Known fire hazards that should be replaced immediately.
Rewiring as Part of a Larger Project
Whole-house rewiring is often done during a major remodel when walls are already open. This is the most cost-effective time to rewire because drywall access is already available. A rewire always includes a 200-amp panel upgrade and is the ideal time to add whole-home surge protection, hardwired smoke detectors, and dedicated circuits for a generator or EV charger. As a licensed general contractor, C.S.W. Power Solutions handles all drywall repair, painting, and finish work in-house — no need to hire a separate contractor.
