DIY electrical
There is nothing worse than seeing when people who are not experienced handymen try doing their own electrical wiring work. Sure, they may be able to get something going and working properly, but they probably skipped all the safety precautions to get there. This could result in a fire somewhere later down the road.
That’s never a good thing that you want to happen in your new home, so make sure you call someone who knows what they are doing to fix that. The last thing you want to come home to is everything up in flames because of the previous owner’s mistakes and poor workmanship.
