Some people find a house rewire messier than others, but it can depend on how much of a neat freak you are and how neat and tidy the electrician is! In all seriousness though, you can expect to encounter a fair amount of mess depending on how much needs to be done.
In many cases the electrician will need to gain access through the floorboards to run wiring underneath the floors. This will mean taking up carpets and other flooring materials. It’s not an easy, clean or tidy task in the majority of cases.
One of the messiest jobs involves chasing out the walls to provide room to accommodate the new cabling. Imagine chasing out a channel along the middle of just one wall in your home. Imagine the amount of dust and dirt this would create. Now imagine the same thing happening in virtually every room in your home. This is what could happen when you require a full property rewire.
There is also the process of replastering after the work is done. Once you factor everything in you’re going to end up with a dusty and messy house until the dust settles (literally) and the work is completed. Even then it will take time for you to get your home fully back to normal, so this isn’t a job to be casually fitted in.
Some people decide to move out while the work is being done. If you have recently bought a house that needs rewiring, it’s certainly better to get the work done before you think about moving in. This will also get the messy job done out of the way before you start thinking about decorating. You don’t need to worry about old carpets or old wallpaper or decoration. Compare that to having a rewiring job done in a newly decorated house with fine furnishings wherever you look.
Another point to consider is the loss of electricity. If you can move out or go away while the work is being done, it might be finished faster than if you stay at the property. If the electrician knows you won’t be there he won’t need to get the electrics back on every evening so you can use them. Similarly he won’t have to tidy up after himself every day to make things halfway decent for you overnight. Instead he can work right up to the end of the day and leave everything as is to return to the next day. You can see how much easier it is to let the electrician get on with things if you possibly can.
The best course of action is to expect a messy job. That way you’ll only be pleasantly surprised if it turns out to be a lot better than you thought. Sometimes an electrician may be able to run new wiring through an existing channel or cable in the wall. This would negate the need for chasing out – which can be one of the messiest jobs of all.
