Drywall questions, answered by experts

It’s a pretty good idea to have drywall corners, also called drywall beading. Drywall is a pretty brittle material and corners tend to be rubbed up against it often. Rather quickly, the edges will start crumbling and you’ll need to replace the entire panel, or add beads on top and repaint the wall. Drywall beads—which are inexpensive—provide long-term support for the drywall and protect your investment.

Cracks, holes, water damage, and dents from heavy equipment often require repair.

You should leave a gap between drywall sheets because they naturally expand and contract along with the building framing as temperature and humidity change. Most pro drywall installers leave a gap of about ⅛ inch between drywall sheets, allowing the sheets to expand, contract, and shift without cracking or becoming damaged. If you don’t leave enough gaps between slabs, the edges will press against each other when they expand, and the pressure can cause visible cracks.

If you're comfortable hanging drywall yourself, you may be comfortable finishing it. But it's worth noting that finishing drywall adds several steps to the process and a lot of waiting time. Hiring a drywall installer may be the way to go if you'd rather spend your time doing other things or are nervous about leaving a rough surface.

You’ll get better results if you soundproof the whole wall. A hole through which light can pass can also let sound waves in. Acoustical or silicone sealant applied to holes and cracks can block enough sound to make a difference. However, the more layers absorb vibrations and slow or stop sound waves, the less noise you’ll have.
