When it comes to a sturdy fence that lasts, the choice of fence post is crucial. Durable fence posts are a foundational element that is the mainstay of your fence’s longevity and durability. However, one of the common issues with fence posts is the need to prevent fence post rot.
This silent destroyer will compromise the integrity of even the most robust fence. Understanding fence post rot and how to select resilient materials is not just a matter of maintenance – it is a matter of safeguarding your investment and ensuring your boundary stands the test of time.
A background to fence post rot
This is a common issue that shortens the life span of your fence posts and in turn your fence. To prevent fence post rot, you must prevent contact with a wood fungus that thrives in moist soil. Several types of fungus attack fence posts, they are called outdoor fungus (Lentinus Lepidus) or bracket fungus, also known as wet rot.
Environmental factors such as rain, humidity and poor drainage make fence post rot more likely. The material of the fence post also plays a part, while metal and concrete posts can suffer from corrosion and cracking, wooden posts mainly fail due to wood rot.
Prevention is better than cure
To prevent posts from rotting, it is essential to use rot-resistant fence posts, most likely to be pressure treated wood, which undergoes a process that makes it virtually impervious to the rot fungus. We will discuss other factors such as proper installation, the use of gravel boards and regular maintenance to safeguard your fence post against wood rot.
Prevention is always better than cure, so by buying lost-lasting fence posts and looking after them, you can prevent fence post rot.
Choose long lasting fence posts
We have already talked about selecting long-lasting fence posts, but it is worth repeating ourselves as it is a crucial part of how we prevent fence post rot. Here is a list of choices for garden fence post installation:
Treated wooden fence posts
These are a popular choice; they undergo pressure treatment with wood preservative to prevent fence post rot, decay, and insect infestation.
Vinyl fence posts
While more expensive, vinyl or plastic fence posts offer excellent longevity and require minimal maintenance.
Metal posts
Often made from recycled galvanised steel or aluminium, metal fence posts are durable and are often treated against corrosion and rust.
Concrete posts
Concrete fence posts are made to last but may not be a planet-friendly choice. The manufacturing of cement is a key component of concrete and is highly intensive to produce requiring a lot of carbon dioxide. Other materials used to manufacture concrete include limestone and clay, these are both resources associated with habitat destruction.
Each material has its own set of benefits, and the best choice will depend on your needs, budget and the climate in your area. Proper installation and regular maintenance can further enhance the life expectancy of your fence posts and prevent fence post rot.
What type of fencing is the most durable?
When considering what type of fencing is the most durable you should evaluate a variety of materials and systems:
- Wooden fencing - while traditional, classic, popular and aesthetically pleasing, wooden fencing requires the most maintenance to prevent posts from rotting and insect damage
- Metal fencing - wrought iron and aluminium are highly desirable and are much more rot-resistant than wood, they are very expensive to install and are not maintenance-free
- Composite fencing - made from a mixture of recycled wood fibres and plastic; composite is designed to look like wood while being more durable and time-consuming
- Vinyl fencing - much like composite, vinyl is a hard-wearing alternative to wood and metal. It is low-maintenance and does not rot. However, the upfront costs are higher compared to other materials
Each fence type has its own set of pros and cons regarding durability, maintenance, and cost. The choice ultimately depends on your needs and preferences and the overall aesthetic effect required.
Cost vs. longevity in fence post selection
Choosing high-quality durable fence posts causes higher upfront costs, but the long-term savings are worthwhile. Investing in pressure treated wood posts or vinyl or metal posts that resist rot, decay and corrosion means fewer replacements and repairs over time.
Depending on your material choice the initial expenses seem greater, these materials offer longevity and dependability, reducing the frequency and cost associated with maintenance.
It is a fine balance between paying more now and saving time and money later. Ultimately, selecting durable rot-resistant fence posts is a wise investment that can lead to cost savings and, way less hassle in the long run.
Special considerations for wooden fence posts and fencing
The most common form of fence post and fencing is the wooden variety. It’s typically one of the cheapest and most versatile materials to work with but also the most susceptible to rot, so let’s look at how to minimise rot and help ensure you install long lasting fence posts.
Use pressure treated wood
Pressure treated fence posts provide the simplest way to ensure durability. Just to hammer home on this point, pressure treated fence posts have been impregnated with wood preservatives that make them resistant to rot, decay, and insect infestation, however preventing decay does not stop there!
Consider climate, soil conditions, and drainage
Make sure you consider the climate and soil conditions in your area when selecting fence posts as these factors affect their lifespan. You need the soil to have adequate drainage, so your fence posts are not sitting in pools of water and decaying faster than they would with proper drainage.
Design considerations and accessories
Choose the correct size post as the size and shape can determine how well the post withstands the weather. Using accessories such as fence post caps, post brackets and gravel boards are some other ways to protect fence posts from rot.
Regular inspections and cleaning wooden posts regularly
Clean your wooden fence post lines regularly, this can help prevent rot and cleaning will reveal any signs of a problem with your fence posts. Treat a wooden post regularly with a protective coating, this applies also to metal fence posts. Catch problems early and applying wood preservative or metal sealant provides an extra layer of weather protection. Remember, prevention is always cheaper than cure, so keeping an eye on your fence posts and acting accordingly is a must.
By following these considerations and maintenance practices, you can prolong the life of your fence posts and fence panels.
Installation tips for enhanced durability
For enhanced long lasting fence posts pre and post-installation, here are some proper installation techniques that help:
- Post depth – the post depth must be adequate. At least a quarter of the fence post should be buried in the ground, e.g. an 8’ fence post is required for a 6’ fence panel
- Use gravel or hardcore – gravel or hardcore is a must when securing fence posts. Placed in the base of the fence post hole gravel or hardcore promotes drainage
- Concrete - use a concrete mix in the hole to secure the post firmly in place
- Check and double check – regularly check your aliment, if your posts are not level neither will your fence be. This seems obvious but it is a common fail
Significantly extend the life of your fence posts and prevent fence post rot by considering these tips when installing your fence posts.
Final thoughts
Think about fence panels as an investment in your fence’s foundation and do not skimp on the initial outlay if you want long lasting fence posts. As any carpenter will say, it is like making sure you measure twice and cut once. Being a little spendy at the beginning is a money saver in the end. Make preventing fence post rot and ground line rot a priority before you put a post in the ground.
