It’s best to set extra time aside in case there are any issues or something happens which is out of your control. A variety of factors can lengthen the time it takes to fit a carpet. These include: Shape of a room: A squared or rectangular shaped room will take the least amount of time. Removal of any furniture: You can save time on carpet fitting costs by removing the furniture and other items affecting the ability to fit the carpet. Removal of any pre-existing flooring: Ranging from 15 minutes to several hours.
