5 Common Fencing Mistakes Brisbane Homeowners Make

A new fence should last for years without giving you trouble. But when certain steps get skipped or shortcuts get taken during installation, problems show up fast. Here are five of the most common fencing mistakes we see across Brisbane, and how to avoid them.

1. Ignoring the Landscape and Slopes

Brisbane is full of sloping blocks, and a fence that works on flat ground does not automatically work on a hill. If the slope is not accounted for during planning, you end up with awkward gaps at the bottom, uneven panels, or posts that are not plumb.

On sloped sites, the fence needs to either step down in sections or follow the contour of the land. Both approaches work, but the method has to be decided before installation begins, not halfway through. If your yard has any grade to it, make sure whoever quotes the job has walked the site and measured the fall.

2. Shallow Post Holes

This is probably the single biggest cause of fence failure in Greater Brisbane. Posts that are not deep enough will lean, shift, or blow over in the first decent storm.

As a general rule, post holes should be around one-third the total length of the post. For a standard 2.4-metre post, that means roughly 600 to 800 millimetres deep, set in concrete. In softer or sandy soils, you may need to go deeper. Skipping depth to save time is never worth it.

3. Incorrect Post Spacing

Posts spaced too far apart put extra stress on the rails and panels between them. Over time, this leads to sagging, warping, or panels pulling away from fixings. For most residential fencing in Brisbane, post spacing should sit between 2.4 and 2.7 metres, depending on the material and fence height.

Going wider than that to save on materials is a false economy. The fence will not hold up, and repairs will cost more than the extra post would have.

4. Ignoring Wind Load

South-east Queensland gets some serious wind events, especially during storm season. A solid fence acts like a sail, and if it has not been built to handle wind pressure, it will come down.

Wind load matters most on Colorbond and other solid panel fences. The solution is straightforward - proper post depth, correct concrete footings, and appropriate spacing. Exposed or elevated properties may need additional bracing. If your property sits on a ridge or faces open ground, mention that to your fencer before the job starts.

5. Not Planning for Maintenance

Every fence needs some level of care, and failing to plan for that from the start leads to early deterioration. Timber fences need regular painting or staining. Colorbond fences need the occasional wash to remove dirt and salt buildup. Gates need their hinges checked and adjusted.

The material you choose should match the maintenance you are realistically willing to do. If the honest answer is "very little," that should influence your choice of fencing material from day one.

Get It Right from the Start

Most of these mistakes come down to planning. A proper site assessment, the right materials, and correct installation make the difference between a fence that lasts and one that causes headaches. If you are planning a new fence in Brisbane, we are happy to walk through the details with you.
