Most electrical wires in homes are hidden behind drywall to protect and hide unsightly wire bundles. Sometimes it becomes necessary to pull wires through walls if, for example, you are adding an outlet or switch to a space. Running electrical wire through closed walls is a tedious project that few do-it-yourselfers enjoy. It is inefficient and time-consuming to remove entire sheets of drywall just to access wire. Rather, you want to remove the smallest section of drywall possible, while maintaining a large enough opening to insert tools and hands. However, sometimes you’ll need to cut drywall across an entire room to adequately run wires.
Handling the electrical wiring takes priority over the aesthetics of cutting into drywall, but it helps to know the best ways to minimize the damage you’ll inevitably inflict on the walls to run the wire. Understanding the nature of drywall, studs, and electrical wire and how they interact lets you push through this side project with greater ease. It’s also important to note that most electrical work, including running new wires, requires an electrical permit in most communities. If you are uncomfortable tackling DIY electrical wiring projects, it is always best to hire an electrician.
