Which of the following is an example of a visible defect?

A visible defect refers to any flaw or issue that can be easily seen or identified without requiring extensive investigation. Improper installation is a prime example of this because it results in visible symptoms, such as misaligned components, gaps, or areas that do not fit together properly. These issues can be readily observed during a walkthrough or inspection of the property, allowing for immediate recognition of the problem.

On the other hand, defects of omission, improper materials, and improper maintenance may not be as readily visible. Defects of omission often involve things that were never installed or done at all, making them less obvious to someone simply observing a property. Improper materials might not present itself visually but could manifest through performance issues over time. Improper maintenance can sometimes be subtle and might require a closer examination to identify the underlying cause, rather than being outright visible at first glance.
