A friend of mine, who’s in the real estate business, recently came across an old house which needed renovations before putting it up for sale. One of the repairs needed was rewiring the whole house. The biggest challenge was that the house had plastered walls which triggered the question, how do you rewire a house with plaster walls without ruining the walls? Here is what I found out.
Have a Plan
Take an inventory of the number of connections you need as compared to what is currently in place. You may need to interconnect some sockets, for example, if they are on the same wall.
At the back of your mind, do not forget which appliances you have in your home, for example, a microwave, toaster, heater, television etc. Another thing you should have in mind is where you would like these appliances placed in your home. This is crucial as you need to figure out where you will place outlets and sockets.
Having the right tools is critical. When it comes to drilling holes, having the right drill is crucial since you need to drill just the right sized hole, not too big or too small, to ensure you cut back on damages made on the walls and in turn reducing your cost of fixing it. You will definitely need the right tools to patch up the damaged walls. Also, remember that plastering walls and leaving them looking as good as new is not that easy, so have the right person for the job.
Be creative and innovative.
Depending on your budget, distinguish between what needs to be replaced and what doesn’t. In case your house has the knob and tube wiring and it is functional, you need to replace it, but at the same time remember that it’s very difficult to track down a shot in this kind of wiring. If you choose to take this path, I would suggest you add new wiring that’s up to standard and can handle more power just to be safe.
Reading books and subscribing to informative sites is also instrumental in building your skill-set. I recently read about a new technique, which is similar to Cove Mould wiring. The site explained that one should run the wiring underneath the finish plaster in the gap that is behind the baseboard. In the corners, you should put a bend in the wire to allow for a change in direction. Its advantage is it’s not visible outside the walls and the wiring is protected by a metal covering.
Consider the kind of home you are working on
If it is more than a one story house, consider running the wires vertically. You could drop the wiring from the attic or from the basement. This is only possible if you have circuits in the attic or the basement. By adopting this technique, you save time and resources because you end up drilling fewer holes into the walls.
With these tips, I don’t see how you could possibly go wrong.
