Which trade seals the head and butt joints for the drywall in commercial projects?

The answer is B, as the taper is responsible for sealing the head and butt joints in drywall installations, particularly in commercial projects. Tapers apply joint compound and tape to the joints where two pieces of drywall meet, ensuring a smooth, even finish that is both aesthetically pleasing and structurally sound. This process involves blending the seams so they are nearly invisible after finishing.

The taper's specialty lies in the precise application of compound and tape to these joints, which are often the most visible areas in a drywall installation. The skill needed to finish these joints correctly is essential for achieving a professional-grade wall that meets building codes and quality standards.

In contrast, the drywaller is primarily focused on hanging the sheets of drywall and preparing the structure, while the finisher typically handles the final texture and paint finish after the taping is completed. The framer's role is to build the framework that supports the drywall, which occurs before any drywall installation begins. Therefore, while all these roles contribute to the overall drywall installation process, the taper specifically oversees the critical step of sealing the joints.
