Signs Your Home Needs Rewiring

Licensed electrician completing whole-house rewiring with new copper wiring in San Antonio TX home by C.S.W. Power Solutions
  • ⚠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.

Frequently Asked Questions

Whole-house rewiring in San Antonio typically costs $8,000 to $20,000 for a standard 3-bedroom home, depending on the home's size, number of circuits, accessibility, and whether walls need to be opened. A 200-amp panel upgrade is usually included. C.S.W. Power Solutions provides a detailed, room-by-room estimate before any work begins.
A complete whole-house rewire typically takes 5 to 10 days for a standard home. The timeline depends on the home's size, accessibility of wiring paths, and whether drywall needs to be opened and repaired. We coordinate all inspections and minimize disruption to your daily routine.
Signs your home needs rewiring include: aluminum wiring (common in 1960s-70s homes), knob-and-tube wiring, frequently tripping breakers, flickering lights, discolored or warm outlets, burning smell near outlets, two-prong (ungrounded) outlets throughout the home, or a Federal Pacific or Zinsco panel. Homes built before 1980 that have never been rewired should be inspected.
In most cases, you do not need to move out. We work room by room and maintain power to as much of the home as possible throughout the project. There will be brief periods when power to specific circuits is shut off. We discuss the schedule in advance so you can plan accordingly.
Some drywall access is typically required, but our electricians minimize wall openings by using existing pathways, attic and crawl space access, and fish tape techniques. Any drywall that needs to be opened is patched and repaired as part of the project. As a licensed general contractor, C.S.W. Power Solutions handles all finish work in-house.
Yes. A whole-house rewire almost always includes a 200-amp electrical panel upgrade to support the new wiring and modern electrical loads. The panel upgrade includes a new main breaker, individual circuit breakers for each circuit, AFCI/GFCI protection where required by code, and CPS Energy coordination for the meter reconnection.
