House Rewiring Service


Wiring issues in houses can be extremely dangerous; faulty or old wiring can cause blown fuses, tripping of electrical systems, and even has the potential of setting your house on fire. Therefore, rewiring a house by a qualified and expert electrician is recommended to ensure your home’s safety.

Signs Your House Needs Rewiring

If you see the following signs, it’s time to consider home rewiring:

  • When bulbs in your house are constantly dimming and flickering, there is a chance that you may have faulty wiring.
  • If you notice any nasty burning smell, which is commonly emitted by faulty wires, consider getting house rewiring services from a well-reputed company.
  • Keep checking your switches or sockets to see if there are any burnt marks, which are typically caused by tiny fires or electric sparks.
  • In case of constant tripping of the fuse board, you may need to replace it or rewire your house.
  • When you plug in an electrical item and see a spark around the socket, it could mean your electrical system has to be rewired. It is absolutely time to call the experts if the plug gives you a small electric shock.
  • Buzzing or crackling is a sign that an electrical circuit is failing. Contact an electrician if you hear any strange sounds originating from a plug socket so they can investigate.

Benefits of House Rewiring

Protection from Electrical Accidents: Faulty or old wiring can cause burns, shocks, and even deadly injuries, risking your family and property. A house rewiring service can keep you safe from all kinds of electrical mishaps.

Save Your Money on Bills: Faulty wiring could hugely impact your electricity bills, as it causes power leaks, which means more electricity is drawn out of the outlet than you need. A house rewiring can help you save power and reduce bills.

Regulatory Compliance: A home rewire keeps your building compatible with the latest safety regulations, addressing frequent hazards and implementing the necessary safety measures.
