Full house rewiring is one of the most important investments you can make for an older Petaling Jaya property. With many terrace houses in SS2, Section 14, and Damansara Jaya dating back to the 1970s and 1980s, outdated wiring is a genuine safety concern — and a barrier to installing modern appliances like aircon units, EV chargers, and smart home systems.
This guide covers what rewiring actually costs in 2026, what factors affect the price, and how to get the best value from a certified electrician.
Average Rewiring Costs in Petaling Jaya (2026)
| Property Type | Typical Cost Range (RM) | Timeframe |
|---|---|---|
| 2-bedroom apartment | RM2,000 - RM4,500 | 2-3 days |
| 3-bedroom terrace house | RM3,000 - RM8,000 | 3-5 days |
| 4-bedroom semi-detached | RM5,000 - RM12,000 | 5-7 days |
| Bungalow | RM8,000 - RM20,000 | 7-14 days |
These ranges reflect 2026 pricing for the Petaling Jaya area. Actual costs depend on several factors specific to your property.
Factors That Affect Rewiring Cost
Property Size and Layout
Larger homes require more cable, more outlets, and more labour hours. Multi-storey properties in PJ’s residential sections add complexity due to vertical cable runs.
Wiring Method
Concealed wiring vs surface wiring significantly affects cost. Concealed wiring (inside walls) costs more due to hacking and plastering work, but delivers a cleaner finish. Surface wiring is cheaper and faster but visible.
Existing Wiring Condition
Properties with asbestos-containing materials, corroded conduits, or non-standard wiring layouts require additional labour. Some older PJ homes have aluminium wiring that must be completely replaced with copper.
DB Box Upgrade
Most rewiring projects include a DB box upgrade with modern MCBs, RCCBs, and surge protection. This adds RM800-3,000 depending on the panel size and number of circuits.
Number of Power Points
More outlets, switches, and light points means more cable and more labour. Modern homes typically need 2-3 times more power points than the original wiring provided.
When Should You Rewire?
Consider rewiring if your Petaling Jaya home shows any of these warning signs:
- Frequent DB box tripping
- Burning smell from outlets or switches
- Warm or discoloured outlet covers
- Flickering lights across multiple rooms
- Two-pin sockets without earthing
- Wiring over 30 years old
How to Get the Best Quote
- Get multiple quotes — We recommend getting 2-3 quotes from Suruhanjaya Tenaga certified electricians. Avoid quotes that seem unusually low — they often mean shortcuts on materials or safety.
- Ask about materials — Insist on SIRIM-approved cables and components. Cheaper, uncertified materials save money upfront but create safety risks.
- Check credentials — Your electrician should hold valid Suruhanjaya Tenaga certification. Ask to see their credentials before work begins.
- Request a detailed breakdown — A professional quote should itemise materials, labour, and any additional work like DB box upgrades or TNB coordination.
