Problems with Drywall Joints
At times, homeowners make the mistake of fitting drywall joints too tightly. It may sound like not much of a problem, but fitting two adjoining drywall sheets closely side-by-side increases the risk of the drywall breaking off. Changes in temperature contribute to the expansion and contraction of the drywall’s underlying wood, and allowing space for it to expand and contract is a must when fitting drywall joints.
On the other hand, some people end up having drywall edges that need to be connected, but don’t have any means to do so. To remedy this, they mud these two edges over and simply hope for the best, something that can result in a cracked drywall in a matter of months.
