This is our second bedroom where we put in Mohawk carpet in the last 6 years. Both carpets had a straight line about 10 to 12 inches from the wall. The company we went with say they have never seen this issue before. Strange that I would have the same issue twice.The first carpet was " Home Run" which they do not make anymore the most recent was the "Creative Factor III " . The line appears to show because of a slight height difference. It has been 26 days since install and a claim has been filed. We are sitting on a empty room as I am not going to put closet and entry doors back on just to remove them again. I am not happy with the Mohawk carpet brand at this time.
