One thing I’m realizing as I get older…. Staircases are getting longer and carpeted areas in homes are getting way larger :-).
One of the heaviest trafficked areas of most homes and businesses are the stairs! Add to this the extra pressure (grinding in) that foot traffic adds, the frequency of use, etc. and you have all the needed components to really damage (a braid) carpet fiber.
We not only spend a lot of extra time focused on all heavily trafficked areas including the stairs, but also always use cleaning products that will help guard against future damage from abrasion.
