Drywall normally has a lifespan of 30 to 70 years when cared for properly. It’s vulnerable to moisture, so it may have a slightly shorter lifespan in damp climates. Having a well-sealed and insulated home and removing any insects or termites can help prolong the life of your interior drywall.
Drywall is made of two layers of paper with a layer of gypsum in the middle, usually used for interior wall construction. Plaster is not used for construction itself; instead, it’s a paste-like material that’s applied on top of sturdier construction pieces. Plaster is often used to add decorative touches to older or historic homes.
Depending on the size of your home, it can take anywhere from three days to two weeks to install drywall in an entire home. A four-person team can install between 45 to 80 drywall sheets per day, although additional time will be required for sanding, finishing, or painting.
