What is the function of a carpet stretcher?

The function of a carpet stretcher is primarily to stretch the carpet tight during installation, which is essential for achieving a smooth and professional finish. When a carpet stretcher is utilized, it helps to eliminate any potential wrinkles or buckling that may occur if the carpet is laid down too loosely. Proper stretching ensures that the carpet lies flat against the subfloor, which can enhance the longevity of the flooring and improve its overall appearance. A well-stretched carpet also reduces the likelihood of tripping hazards and makes the surface easier to clean, as it prevents debris from collecting in creases or folds.

The other options do not accurately reflect the purpose of a carpet stretcher. Making the carpet waterproof is not a function of this tool; rather, that would relate to the application of specific treatments or materials. Measuring the carpet for cutting is typically done with a measuring tape or similar tool, rather than a stretcher. Lastly, lifting the carpet for cleaning is also not a role of a carpet stretcher; rather, it may require specific tools like a vacuum or brush for effective maintenance.
