Your installers will arrive with the knowledge, tools and supplies to lay your new carpet. However, they will need an area to store their electrical tools and access to electrical power outlets for their tools.
Also, vacuum the subfloor after the old flooring and cushion has been pulled up and before the new floor is installed to minimize dirt and dust.
Bear in mind that your new floor coverings need to be installed over a structurally sound subfloor. Any damage that has been done by insects, water, or other problems should be repaired prior to carpet installation.
In the months following installation, you may notice some shedding or sprouting. This is normal and will not affect the carpet’s life or beauty in any way. Shedding is when loose fibers become undone from carpets made with staple yarn. This is normal and subsides within a short time with vacuuming. Sprouting is when a single tuft extends beyond the carpet surface, usually along walls or at seams. Simply clip it off; do not pull.
