If your carpet has ripples or waves in it then it needs to be stretched. I am an expert at this. I even do it for other carpet cleaning companies that dont do repairs. Sometimes the homeowner does'nt even know it can be fixed. Proper carpet installation is critical to getting the full life out of your carpet. If it was not stretched tight enough originally, develops bubbling along the walls, or ripples and waves anywhere in the room it can be fixed.
