Wet Drywall Replacement
Understanding the nature of drywall is crucial to understanding whether or not it needs a replacement. Drywall is made from layers of compressed gypsum plaster that is sandwiched between cardboard or paper. The paper and cardboard start to disintegrate when they come into contact with water, and moisture can penetrate the gypsum plaster layers, causing warping, swelling, and mold growth. When it gets wet, it loses its strength and becomes soft, making it difficult to support weight or load-bearing features. When the wet drywall is in an essential part of the house such as the ceiling or wall, it can weaken the structure leading to sagging or even collapse. Even if the damage seems minor, it can be difficult to accurately assess the extent of the damage from the outside. It is advised to employ the services of a professional to evaluate the extent of the damage.
In most cases, wet drywall needs to be replaced, especially if the damage is extensive. Small amounts of drywalls that have been contaminated with clean water from a sink leak, for example, can be dried if caught early.
