In most cases, no, you won’t need a permit to replace drywall. If you’re changing the floorplan of your home by adding or removing walls during the drywall project, then you might need a permit, but replacement or repairs usually doesn’t require a permit. Your drywall professional should be able to confirm whether or not a permit is required for your project. If it is, it’s likely to add between $50 and $150 to your total cost. Keep in mind that you will need permits if you plan to install new electrical wiring or plumbing lines behind your new drywall.

In most cases, walls don’t have to be removed to rewire a house. Much of the new wiring can be run through attics and crawlspaces, and then electricians often use a tool called fish tape to pull the cables through the walls via cut access points that can be easily patched up without requiring any major demo work.

You should start looking for a drywall installer by choosing a local company with positive online reviews and ratings with the Better Business Bureau (BBB). Next, confirm that the professional is properly licensed using Angi’s contractor licensing tool, and ask the installer if they are fully insured. It’s a good idea to ask for recent customer references and call them to get their honest opinion about the contractor and their work. You can also ask the installer if they guarantee their work or provide a workmanship warranty.

Whether you can reuse a drywall anchor or not depends on the type. Plastic expansion anchors and plastic self-drilling anchors, which expand once screwed into the wall, are single-use only. You can't straighten and reuse them after removing them from the wall.

Metal toggle bolts can be reused, provided you can successfully remove the toggle from behind the wall. Once you remove the bolt, the toggle often falls down and can be difficult to retrieve without removing the drywall.
