Why might a builder be advised against using a certain level of finishing in flood-prone areas?

A builder may be advised against using a certain level of finishing in flood-prone areas primarily due to the consideration of flooding risk and the integrity of materials used. In areas susceptible to flooding, the risks associated with damage to structures from water intrusion are significantly higher. Certain finishes, especially those made from absorbent or less durable materials, can become compromised when exposed to moisture, leading to issues such as mold growth, decay, or structural weakening.

Using materials that are not suitable for flood-prone environments can result in costly repairs and renovations following a flood event. Therefore, opting for finishes that are water-resistant or can withstand occasional flooding is crucial for maintaining the integrity and longevity of the building. This approach not only protects the investment but also ensures the safety and habitability of the structure over time.
