Deciding whether to repair or replace racecourse fences and hurdles is rarely straightforward. Components age at different rates, budgets are finite, and the cost of something failing on raceday is high. This guide covers the key decision points for each component type so you can approach close season inspections with a clear framework.
Ash frames: repair or replace?
Ash frames can last a long time with proper maintenance and storage. Splits running with the grain in secondary members are often acceptable and should be monitored. Rot or structural splits in the main uprights or base rails are a different matter. If an upright cannot bear load reliably, the frame should be replaced. As a rough guide: if three or more structural members are compromised, the cost of replacing individual components usually approaches the cost of a new frame, making outright replacement the more sensible call.
PVC face boards
Individual PVC boards can be replaced without replacing the whole fence. A cracked board should always be replaced, not repaired. PVC does not respond reliably to adhesive repair under impact loading. If several boards on a single fence are cracked or deformed, replace the full face at once. It is a good opportunity to inspect the fixings behind each board, which are difficult to check while the facing is intact.
Birch fill
Birch fill can be topped up when it is thinning but structurally intact. If it has compressed to the point where it no longer presents a brush face and the frame is being exposed, replace it entirely. Topping up over severely degraded fill does not produce a good result and the new material will not bind well with the compressed base.
Roll-on/roll-off mechanisms
Bent or seized locking pins should be replaced, not straightened. A pin that has been forced is weakened even if it looks straight, and a fence that can move out of position on raceday is a serious safety risk. Worn hinge bearings should be replaced as a precaution. The cost of a bearing is small; the cost of a fence shifting under load is not.
Hurdle flights
Individual hurdle frames can be replaced within a flight set. If a flight has two or more structurally compromised frames, replace the full flight. Mixed-condition flights are harder to inspect reliably and tend to deteriorate faster because wear is uneven.
A general rule
If the repair cost exceeds 60 per cent of the replacement cost, replace it. You get a known condition, a full service life and no residual doubt about what you might have missed. WF Racing stocks spares for most of the products we supply. If you are unsure whether something is worth repairing, give us a call for an honest assessment.
Frequently Asked Questions
How long do steeplechase fences last?
There is no fixed lifespan. With proper maintenance and close season storage, ash frames can remain serviceable for many years. The key factors are how many meetings the fence is used for each season, how well it is stored when not in use, and how promptly worn components are replaced. Frames with ten or more seasons on them warrant close inspection regardless of appearance.
Can a bent locking pin on a roll-on/roll-off fence be straightened and reused?
No. A pin that has been bent or forced should always be replaced. Bending weakens the metal even if the pin appears straight afterwards. A fence that can move out of the locked position on raceday poses a serious safety risk and is likely to fail a pre-race inspection.
Is it worth repairing a fence frame with rotted uprights?
Generally not. Rot in a structural upright compromises the load-bearing capacity of the frame. The cost of replacing the upright typically approaches the cost of a new frame, and a repaired frame carries residual uncertainty about its integrity. In most cases, replacing the frame is the safer and more cost-effective decision.
Can individual PVC boards be replaced without buying a new fence?
Yes. PVC face boards are available individually and can be replaced without replacing the whole fence or frame. This is a straightforward job during the close season. WF Racing supplies replacement PVC boards for the products we manufacture.
How do I know when birch fill needs full replacement rather than a top-up?
Top up when the fill is thinning but still presenting a brush face across the width of the obstacle. Replace entirely when the fill has compressed to the point where the frame or face boards are being exposed. Topping up over severely degraded fill does not produce a good result.
