Carpet bubbles and buckling are typical signs of improper carpet installation if the carpet is cleaned for the first time in 12-18 months after installation. A carpet that is older and shows signs of buckling and bubble effects before or after carpet cleaning, is a sign that the carpet needs to be re-stretched by professional installers. It is not always possible to know ahead of cleaning if the carpet will react in this manner. If bubbles or buckling do occur during the cleaning, it will go down within 24-48 hours and will be virtually unnoticeable. At Wiz Team, Inc. during our in-home consultation, we will point out any possibilities for buckling or bubbling before cleaning. We recommend carpet cleaning to be performed first and then see how much of the buckling will re-stretch itself during drying time, whatever is not back to normal, should be re-stretched by one of our recommended vendors.
