How Wind Affects Your Fence

Many people don’t realise that wind is one of the biggest forces acting on a fence.

Every gust places pressure on the fence panels, rails and posts. Over thousands of windy days, that pressure can eventually cause poorly built fences to lean, loosen or fail.

At Crawfords Fencing, we design every fence with Melbourne’s weather conditions in mind.

Why Does Wind Damage Fences?

A solid fence acts much like a sail.

When strong winds hit a privacy fence, the force is transferred into:

• The palings or sheets.

• The rails.

• The fence posts.

• The concrete footings.

• The surrounding soil.

If any part of that system is inadequate, movement can occur.

The Posts Do the Hard Work

Many people think the palings are the important part of a fence.

In reality, the posts carry almost all of the structural load.

That’s why correct post sizing, footing depth and quality concrete are so important.

A fence is only as strong as the posts holding it up.

Why Some Fences Survive Storms

After major storms, you’ll often see one fence standing perfectly straight while the neighbour’s fence has collapsed.

The difference usually comes down to:

• Correct footing depth.

• Quality concrete.

• Proper post spacing.

• Suitable materials.

• Good workmanship.

• Site conditions.

Strong fences are designed long before the first paling is installed.

Why Chainmesh and Tubular Fences Last So Long

One advantage of chainmesh and tubular steel fencing is their open design.

Unlike solid timber or Colorbond fences, they allow wind to pass through rather than acting as a large sail.

This greatly reduces the load placed on the fence posts and is one reason quality chainmesh and tubular fences can often remain standing for 40–50 years or more.

Wind and Colorbond Fencing

Colorbond fencing performs extremely well when installed correctly.

However, because it forms a continuous solid panel, it’s important that the fence is built to suit the conditions.

Post spacing, footing depth and correct installation all play an important role in long-term performance.

Wind and Timber Fencing

Timber paling fences also experience significant wind loading.

The stronger the wind, the greater the force transferred into the posts below ground.

At Crawfords Fencing, we take these loads into consideration when selecting post sizes, footing depths and installation methods.

How Crawfords Fencing Builds for Wind

Every property is different.

Before construction begins, we consider:

• Fence height.

• Wind exposure.

• Soil conditions.

• Fence length.

• Ground levels.

• Existing retaining walls.

• Surrounding structures.

There is no one-size-fits-all approach.

Our goal is to build a fence that will continue performing for decades, not just look good on the day it’s installed.

Why Quality Matters

Most fence failures don’t happen because of one strong gust of wind.

They happen because years of wind gradually expose weaknesses in poor foundations and workmanship.

That’s why we focus on what lies below ground just as much as what you see above it.

As Director Tyrone Crawford often says:

“Wind will always test a fence. The question is whether the fence was built properly in the first place.”
