Prepare to cut and screw drywall, leave the proper gap distance for any seams, never leave the end of a piece of drywall hanging off of a stud, and cut out around electrical boxes and switches. Plus, getting the drywall to look good is challenging, especially when taping and spackling. That’s why it’s usually a better idea to hire a professional drywall installer to ensure high-quality results.
