Closeboarding on Slopes: Navigating Challenges and Ensuring Precision

Closeboarding, a favored fencing technique, becomes particularly challenging when installed on sloping terrains. While the posts may have even marks at their tops, relying solely on these can lead to noticeable discrepancies in the fence line's appearance and structure.

The Importance of Using a String Line on Slopes

When fencing on a slope, the traditional markings on posts become insufficient guides. Instead, employing a fencing string line becomes imperative. This line, when set at the desired height, serves as a consistent reference point, ensuring that the boards follow the natural slope of the terrain.

Avoiding Deviations and Achieving Consistency

If closeboarding is installed strictly based on the markings of the posts without considering the slope, several issues can arise:

  • Flat Spots: Boards that are aligned with the post markings might appear flat when viewed from a distance due to the slope, compromising both aesthetics and functionality.

  • Inconsistencies: The fence might have varying gaps between boards, leading to an uneven appearance and potential structural weaknesses.


Closeboarding on sloping terrains demands a nuanced approach. By prioritizing the use of fencing string lines over traditional post markings, one can ensure a fence that not only aligns with the natural contours of the land but also stands the test of time in both form and function.
