Electrical Work In An Old House

When renovating an old house it is always advisable and often legally required to rewire the house to modern standards. Depending upon the age of the house this work can be either fairly straightforward or very difficult and expensive.

If the house is very old then the original wiring could have been installed inside copper conduit, and the wall cladding will probably need to be removed in order to replace the wiring. Sometimes the wiring can be pulled through the conduit, but this is rare.

In older houses it is common for the wiring to have deteriorated, and the insulation could have hardened and cracked or could even have been damaged by Rodents. In any case wiring will need to be replaced with modern wiring and this may involve removing the wall cladding and tidy or removing sections of the wall cladding by cutting it out with a sharp knife. This is much easier to do if the builder is going to be replacing any wall cladding with modern gib lining, and the work for the electrician becomes very much like the work involved in a new home build.

At the very least for an old house it will be necessary to replace all of the lighting and power switches, as these very definitely deteriorate and become unsafe over time. New lighting and power switches can modernise the look substantially, and give a feeling of comfort to the homeowner that their electrical system is safe, but this also needs to be backed up with new wiring in most cases.

The difficulty for electricians Wellington in most renovations of old houses is that modern wiring practices  demand that new wiring the installed from the metre box to individual rooms, and this can mean having to run wiring through the ceilings of an old house and cabling down to the new switches. Conditions can be hot and cramped for the electrician, also was required to do fine delicate work when making safe connections to switches in the metre box.


The electrician can’t really avoid this work, because in the end he or she will need to get it approved by the electrical inspector. This is always or at least should always be a key requirement from any homeowner getting electrical work done.
