Estimated time With drywall, it takes a fraction of the time. Usually, two professionals can cover a 12 by 16 foot room in about an hour. Working so quickly requires practice and some specialized tools. On average, for drywall, a new house takes 6 days to 4 weeks.
However, it depends on several factors. Such as the size of the house, the type of drywall finish, the climate and humidity, the complexity of the frame, the height of the ceiling and wall, etc. The time may vary depending on these factors. Drywall installation takes as little as one day and up to four weeks, including the time it takes to prepare and clean up waste.
The amount of time depends on the size of the project, the framing needs and the level of finish.
