It is possible to install laminate flooring over carpet. For a successful installation, the carpet must be fully adhered, and ideally it should be no more than one-quarter-inch thick.
Laminate flooring is a versatile and easy-to-maintain floor covering, making it a popular option for many homes. While many outlets discourage the act of laying laminate flooring over carpeting, it can be done. Low-pile carpet, such as Berber, is the easiest option since it allows for a more secure base. Laminate on high-pile carpets makes the floor feel as if it's moving and may cause problems underfoot, so this configuration is not recommended.
