Electrical work
Very few DIY home improvement jobs have a smaller margin for error. A momentary concentration lapse or a single wrong move can be fatal.
Most cities require a licensed professional with training, knowledge, and insurance if you want to do any profound wiring and electrical work. Permits are a must, and the work needs to be done to code in order to pass inspection.
According to the National Fire Protection Association, the US has approximately 45,000 electrical fires annually, and amateurs will risk injury.
Removing walls
Removing walls is often a doable option for creating a bigger space or an open floor plan. But before you begin swinging your sledgehammer, get a contractor to confirm that the wall isn’t load-bearing.
Damaging a load-bearing wall can have grave consequences, such as a ceiling caving in. And if that isn’t bad enough, it can also be risky for the homeowner and result in many injuries.
On the other hand, clearing wallpaper only takes a few steps. So that IS a DIY home improvement job you can take on.
