Which of the following is NOT typically included in installation charges for new carpet?

The option indicating that adding decorative trims is typically not included in installation charges for new carpet is accurate because decorative trims are often considered an additional service or enhancement rather than a standard part of the carpet installation process. When charging for carpet installation, companies typically cover the fundamental aspects necessary for laying down the new carpet, such as preparing the site, removing any existing flooring, and installing the required underlay or cushion. These tasks are essential for ensuring the carpet is installed correctly and functions well.

In contrast, decorative trims often involve a more personalized touch, which can vary in choice and style based on the homeowner's preferences. As such, these are best seen as optional and may incur additional charges to cover the extra labor or materials involved. Recognizing this distinction helps consumers understand what standard installation includes and what could involve additional costs.
