Because many properties in Ferntree Gully aren't perfectly level, careful planning before construction is essential. It's common for homeowners to require small retaining walls before new fencing is installed, creating a stable base and helping maintain consistent fence heights across the property. Older fences throughout the area also frequently develop rotting posts, loose palings and leaning sections after years of exposure to Melbourne's changing weather. While some fences can be restored with fence repairs or fence post replacements, others are more cost-effective to replace completely. Timber picket fencing is also becoming a popular choice for homeowners updating the front of their property, while steel gates provide secure side access that complements new boundary fencing. Similar projects are regularly completed throughout nearby Heathmont and Boronia, where properties share many of the same characteristics.
