A factory-built fireplace is _____ expensive to install than a masonry fireplace.

A factory-built fireplace is typically less expensive to install than a masonry fireplace due to several factors. Factory-built fireplaces are prefabricated units designed for easier and quicker installation, often requiring fewer labor hours. This streamlined installation process often means reduced costs in terms of both materials and the time required for installation. In contrast, masonry fireplaces involve complex construction techniques that require skilled labor and additional materials, resulting in significantly higher costs. Furthermore, factory-built options are generally lighter and may not require the same structural considerations as masonry fireplaces, leading to lower overall installation expenses.
