Renovating and improving
You may want to consider renovating or improving your home before you put it up for sale. Think about how much money you would spend and whether it’s likely to improve your sale price.
Think about your home’s safety devices. By law, your home should already have certain types of safety devices. You may need to replace or repair old devices, or install anything that’s missing.
A safety switch:
detects certain forms of faults in electric devices
shuts off power through those circuits.
Any home built after 1992 must have safety switches.
Older homes may not have them, but you might still consider installing one because the buyer will have to install one within 3 months anyway.
Do not attempt to do electrical work yourself. Always use a licensed electrician.
