Description
Ball and Acorn Fence Post Finials are the kind of finishing touch that lifts fencing from functional to well-made. They’re small details, but they make a real difference—adding height, visual interest, and that sense of care and attention that marks out a garden that’s been thoughtfully put together.
The turned timber construction gives them a smooth, refined profile. The ball finial is classic and versatile—it suits just about any garden style, from traditional to contemporary, and adds a clean, geometric top to fence posts. The acorn finial has a more country, cottage garden feel—softer and more organic, it sits beautifully in traditional settings or anywhere you want a gentler, less formal look.
Beyond aesthetics, finials serve a practical purpose: they protect the top of fence posts from water ingress. A bare post top (especially a square-cut end) is vulnerable—water sits on the end grain, soaks in, and accelerates rot. A finial sheds water away from the post, extending its life and reducing maintenance.
The pressure-treated timber weathers to a soft silver-grey if left natural, or takes paint and stain beautifully. Painted finials can become a feature in their own right—crisp white for a classic look, dark charcoal for drama, or a contrasting colour to make them stand out against the fence line.
Whether you’re finishing a new fence, upgrading existing posts, or adding decorative detail to gate posts, these finials bring that combination of function and finish that makes a garden feel complete.

Installation
Choosing the Right Finial:
-
Ball Top Finial: Suits formal, traditional, contemporary, and cottage gardens. Works well on gate posts, corner posts, or evenly spaced along fence lines. The geometric shape creates a strong, clean visual line.
-
Acorn Top Finial: Best for traditional, country, and cottage gardens. Softer and more organic than ball finials, they suit rustic or informal settings beautifully. Ideal for gate posts or feature posts.
Post Preparation:
- Ensure the top of the post is clean, dry, and level
- If the post top is uneven or damaged, sand or plane it flat for a secure fit
- Remove any debris, moss, or algae from the post top
Fixing Finials:
- Position the finial centrally on the post top
- Pre-drill holes in the finial base and mark screw positions through the hole
- Pre-drill pilot holes in the post top to prevent splitting
- Apply a small amount of exterior wood glue to the finial base for added security (optional but recommended)
- Fix the finial to the post using galvanised or stainless steel double ended screws (typically 50–75mm long, depending on finial base thickness)
- Ensure the finial is secure and sits flush on the post top
- Wipe away any excess glue immediately
Spacing & Placement:
- Gate posts: Fit finials to both gate posts for symmetry and visual balance
- Corner posts: Add finials to corner posts to mark boundaries and add height
- Evenly spaced: For a formal look, fit finials to every post along a fence line
- Alternating: For a less formal approach, fit finials to alternate posts or only to feature posts
Maintenance
Initial Treatment:
- Finials arrive pressure-treated and ready to install
- For enhanced protection and appearance, allow timber to weather for 6–12 months before painting or staining
- Clean with a stiff brush; apply exterior-grade timber preservative, decking oil, or wood stain
- Pay particular attention to the top of the finial where water can collect
Annual Maintenance:
- Spring: Inspect finials for stability; check fixings and tighten if needed
- Treatment: Apply a fresh coat of preservative, oil, or stain annually to maintain colour and protection
- Cleaning: Remove debris, moss, or algae from finial surfaces, especially around the base where it meets the post
- Water shedding: Ensure finials are still shedding water effectively; replace if cracked or damaged
Longevity:
With proper installation and annual treatment, finials can last as long as the posts they’re protecting—15–20 years or more. Regular treatment is key to preventing splits and cracks.
