How horizontal slats are built
Instead of tall vertical boards, a horizontal fence uses long boards laid on their sides, one above the other, between posts. The slats are fixed to the posts or into a frame, and the length of each slat is set by the post spacing. Because the boards run sideways, the fence reads as a series of clean, level lines across the garden. It is a simple point, but it saves a lot of rework once the posts are in the ground.
The gap between the slats is a choice. Close them up and you get a solid screen. Leave a small gap and light and air pass through, with a lighter, more modern look. Either way, the spacing should be even all the way up, since a drifting gap shows immediately on a horizontal fence. Whichever you pick, the top of each section should be level so the lines read cleanly.
Following the slope around Dudley
A hillside boundary is the hard test for horizontal slats. Long level boards do not bend to follow a falling garden, so the fence is usually built in steps. Each section stays level and drops down to the next, which gives a neat staircase of lines instead of boards chasing the slope at an angle. Taller sections on a slope also catch more wind, so firm footings are never optional.
The alternative is to rake the slats along the slope, which can suit a gentle gradient but looks odd on a steep one. We will go through the options with you on site. Where ground levels change along a boundary, post heights and the stepping pattern need planning before anything is ordered. Ask for a quick sketch of the stepping before work starts, so there are no surprises on site.
Post spacing and strength
Slats are long and carry their own weight sideways, so the post spacing needs thought. Posts too far apart let the boards sag or bow over time. Closer posts keep them straight and make the whole fence stiffer in wind, which matters on exposed higher ground. Wide runs between posts look tempting, but the saving is soon lost if the boards bend.
Posts should be set firmly in concrete footings, with the tops cut to a consistent height or stepped on purpose. A good horizontal fence is quite unforgiving of poor setting out, because every line is visible. That is the trade-off for the clean look, and it is worth building carefully. Cut ends should be treated, because bare end grain takes in water faster than anything else.
Quick tips
- Decide early whether you want a solid screen or a gap between slats, as it changes the whole look.
- On a sloping boundary, ask how the fence will step, and where each post will be, before agreeing a design.
- Walk the full boundary and note any places where the ground rises or falls sharply, then tell us.
- Treat or oil the slats as advised, and keep soil clear of the bottom board to prevent early rot.

Frequently asked questions
How does a horizontal slatted fence cope with a slope?
Long level boards do not bend to follow falling ground, so the fence is usually built in steps. Each section stays level and drops to the next. Raking the slats suits gentle gradients only. In Dudley, plan the stepping and post heights before ordering.
Why does post spacing matter so much with slats?
Slats are long and carry their own weight sideways, so posts too far apart let them sag or bow. Closer posts keep them straight and stiffer in wind, which matters on exposed higher ground. Firm concrete footings and treated cut ends help too.
