Abstract: Various embodiments of the present invention provide tools for assessing damaged floor coverings to determine LKQ replacement values and face weights for carpet. In one embodiment, a method is provided that includes the steps of determining a yarn price constant for a plurality of carpet types, where the yarn price constant represents the price of a single tuft of yarn for a respective carpet type measured at a predetermined pile height and receiving, from a user, data relating to the damaged carpet's construction. The data may further include the damaged carpet's pile height and stitch density. Using a computing device, the yarn type of the damaged carpet is estimated based at least in part on the received data relating to the damaged carpet's construction.
