This story shows how to install carpet on steps.
A carpeted stairway quiets your home by softening footsteps and absorbing sound waves. Carpeted stairs are safer than hard-surface stairs, as they lessen your chances of slipping and pad your fall if you lose your balance.
Building codes control the dimensions of treads and risers. Treads are typically 10 to 11-1/2 inches deep; the deeper the tread, the more comfortable the climb. Risers are generally no more than 7-3/4 inches tall. If your stairs dimensions are not within these guidelines, for safety's sake you'll need to rebuild them.
Stairways get heavy wear, especially along the tread nosing, so choose a carpet that is durable and easy to clean. A carpet with an attached padded backing is easier to put down, but these carpets are not usually recommended for stairways as they have a tendency to wear quickly.
