Signs Your Old Wiring Needs Replacing
Most Egyptian homes were built 30–40 years ago to entirely different electrical standards. Old wiring doesn't fail immediately — it degrades slowly. These seven signs warn you before disaster strikes.

Quick Answer
7 warning signs your home's old wiring urgently needs replacing — for safety and to prevent fires and faults.
7 Signs That Demand Immediate Rewiring
- Over 25 years old without rewiring — particularly in Egypt: if your home was built before 2000 and hasn't been rewired, the wiring needs specialist inspection. Egyptian buildings from 1970–1995 suffer severe ageing because that period saw rapid construction with below-standard materials and methods.
- Aluminium wiring present — how to identify it: open any outlet or switch cover: copper wire is bright orange-gold; aluminium is dull silver or grey. Aluminium expands and contracts more than copper with temperature changes, causing loose connections, electrical arcing, and high fire risk. Replacing it with copper is a necessity, not an option.
- Lights flickering in multiple rooms simultaneously — a main-circuit sign: if bulbs flicker in several rooms at once, the problem isn't the bulbs — it's a weak connection in the main wiring or the main busbar at the breaker panel. Ignoring this means electrical arcing that can start a fire.
- Warm or hot outlets and switches to the touch: heat at connection points means high resistance = deteriorating connection. In Egypt this is most common in outlets carrying a fridge or washing machine — replace the outlet immediately and check the cable for corrosion.
- Breakers tripping repeatedly, especially in summer: the breaker detects overload on cables that can't carry it. Old wiring uses 1.5mm² or 2.5mm² on circuits that originally only carried lighting — now carrying ACs, washing machines, and inverter appliances. The fix isn't raising the breaker rating — it's replacing the cables and adding dedicated circuits.
- Outlets with only two pins (no earth): old wiring typically uses just two conductors (phase + neutral). A three-pin outlet in your apartment may not be connected to a real earth at all — verify this as a top priority.
- Burning plastic or wiring smell, even faint: the PVC insulation on old cables becomes brittle and cracked with age and Egypt's high temperatures — then begins burning under high current. Any electrical burning smell demands immediate inspection, not waiting.
Frequently Asked Questions
Can wiring be replaced while the family is inside?
Not recommended — rewiring typically requires vacating for several days, or working in phases that minimize disruption. Experts plan timing to allow partial use during the work.
Does rewiring require demolishing walls?
Sometimes partially. Usually small slits are cut in walls to pull new cables through, then filled and refinished. In some cases cables can be routed under tiles or through plasterboard ceilings to minimise demolition.
Can electricity still be used during rewiring?
Yes, the electrician works on one circuit at a time. The circuit being worked on is temporarily off while others remain live. Complete apartment rewiring takes 2–5 working days.
What's the difference between rewiring and just adding circuits?
Adding circuits = connecting new runs from the panel to cover a specific need. Full rewiring = replacing all cables from scratch. The former is cheaper but doesn't fix underlying old wiring problems.
How do I know if my apartment's wiring is aluminium or copper?
Easiest method: open any outlet cover (after cutting power or without touching the wires). Copper wire is bright orange-gold. Aluminium wire is dull silver or grey. If unsure, ask an electrician to check the main panel — the wires there are exposed and easy to identify. Most Egyptian apartments built before 1985 use aluminium in their main circuits.
What does labor cost to rewire a 120 m² Cairo apartment in 2026?
Labor only for a 120 m² apartment (3 bedrooms): Bronze 10,800 EGP | Silver 13,200 EGP | Platinum 16,800 EGP.
