When carpeting is installed, the carpet nap is laid in the same direction. Shading is normally found in high traffic areas, such as hallways, and is the result of multidirectional foot traffic, which forces the nap to lie in opposite directions. When viewing the carpet in these areas, it looks either lighter or darker, depending on where you are standing. This condition is not reversible. One way to slow shading is to vacuum your carpet in one direction only. Carpet cleaning often can improve this issue.

Latex is an adhesive material applied by the manufacturer to anchor yarn tufts to the back of the carpet or rug. These adhesives start to break down as soon as the textile is bought by someone and put into a house or office. The rate of deterioration is related to the quality of the adhesives, how they were applied, the conditions under which the textile is being used, and the wear and tear on the carpet or rug. The breakdown may occur in areas that leave the appearance of “bubbles” due to separation of the adhesive. Dragging heavy furniture across the surface, exposure to heat, heavy traffic and wear, and spills can all cause eventual weakening of the latex adhesive. The end result is backing separation that on the topside looks like rippling.
You may notice waves or small ripples appearing in your carpet immediately following cleaning. The reasons for buckling vary:
•If an installer does not power stretch your carpet or fails to do so properly, buckling is assured.
•Improper carpet padding (too thick) can cause buckling. The absorption of moisture/humidity will cause the carpet latex to expand, resulting in buckling. This will resolve itself, however, as humidity in the room returns to normal and the carpet dries.
•Dragging heavy furniture across wall-to-wall carpeting will pull the carpet off the tackless strips, causing waves. Re-stretching would be advised in this case.
Dark edges along walls:
On wall-to-wall carpet this phenomenon can be seen not only on the edges of the carpet near walls, but under doors in the threshold, or even as silhouettes around furnishings or furniture on the floor. This is named “filtration staining” and it is caused by charged particles floating in the air and being driven into carpet by air currents. As they make contact with the yarns, a bonding occurs and makes a dark difficult-to-remove line. This should not be confused with dust build-up, which may follow the same air path just described.
