How to Install Timber Fencing on a Slope: Stepped or Raked?

A sloping garden does not rule out a timber fence, but it affects how the fence line can be laid out. Two common approaches are to step level panels between posts or to rake a suitable fence system so it follows the ground. The right choice depends on the slope, the panel type and the finish you want.

Stepped fencing: level bays along the slope

With a stepped layout, each panel stays level and the fence rises or falls at the posts from one bay to the next. This can work well with compatible ready-made panels and slotted posts. The repeated changes in height create a clear stepped appearance, and gaps may appear below panels where the ground falls away.

Before choosing this approach, walk the boundary and identify where each step would fall. Consider how the gaps will look, whether they affect privacy or pets, and how the lower edge will sit above the ground. Gravel boards may form part of a compatible system, but check the installation details for the actual products.

Raked fencing: following the ground

A raked fence follows the slope rather than staying level in each bay. This can create a continuous line along a gradual incline, but the fence construction needs to suit the angle. Site-built closeboard or other systems designed to follow a slope may offer more flexibility than standard rigid panels.

Do not force or cut a ready-made panel to make it rake unless its manufacturer says that method is suitable. The rails, boards, posts and fixings all need to work together at the chosen angle.

How to decide

Measure the ground levels along the proposed fence run before ordering. Note where the slope changes, where the boundary turns and whether there are existing posts or walls. Then compare:

• Panel type: check whether the product is intended for stepping, raking or level ground only.
• Appearance: decide whether you prefer distinct steps or a line that follows the garden.
• Ground clearance: plan how the bottom edge will sit above changing ground levels.
• Privacy and boundaries: consider gaps, views and the relationship with adjoining gardens.
• Posts and accessories: confirm that lengths, slots, gravel boards and fixings suit the layout.

Measure first and check the full system

Record the total fall and the length of each section, then ask the fencing supplier to confirm a suitable layout before buying. A small level change across several bays may be handled differently from a sharper change in one short section. Posts may need different lengths or positions to accommodate the chosen method, so confirm the details for your system.

If the fence line borders a retaining wall or a raised area of soil, get advice before treating the fence as support for that ground. Ordinary fence panels are not automatically designed to retain soil.

Before ordering

• Survey the slope and mark every change in direction or level.
• Choose stepping or raking based on the product system, not appearance alone.
• Check whether any gaps need a planned solution.
• Confirm compatible panel, post, gravel board and fixing details with the supplier.
• Follow the product installation instructions and use a competent installer if unsure.
