How do I know if my property needs rewiring?
Your home or premises may need rewiring if you regularly experience blown fuses or flickering lights. Other indicators are outdated fuse boxes and discoloured or insufficient sockets. We can carry out a full electrical inspection to assess the condition of your wiring.
How long does a full house rewire take?
The timeframe varies depending on the size and complexity of the property. Typically, a full house rewiring takes between five and ten working days. We always provide a detailed schedule before work begins.
Can I stay at home while the rewiring takes place?
You can sometimes remain in the property during partial rewiring, but it’s usually safer and more practical to vacate temporarily for full rewires. We’ll discuss all options with you in advance.
Are your rewiring services guaranteed?
Yes, Pro-Tech Electrical Bristol offers a one-year workmanship guarantee on all rewiring projects, which provides complete peace of mind.
