Yes, fences should be maintained regularly. This will help keep up their appearance and give them a higher chance of living out their full lifespan. The type of maintenance required will vary from fence to fence. For example, a rust-resistant coating should be applied to chain link fences so they don’t develop rust spots. No matter what type of fence you have, you should clean it when it gets dirty. This will prevent grime and dirt from building up on the surface and adversely affecting its appearance.
