So, you’re thinking about building a fence. The dog keeps getting out, the neighbours can see in, or you just to give your backyard a bit more privacy, we can help. We know it may sound like a major task, building a fence can be a manageable weekend project with the right attitude and equipment. Our simple and easy-to-follow guide will help you design, prepare, and build yourself a long-lasting, attractive fence.
Step 1: Know Why You’re Building It
Before you start digging holes, understand your why. Are you after privacy? Security? Decoration? Keeping livestock in or kids safe? The purpose will guide your material choice (timber, metal, wire, etc.) and design (paling fence, picket, post-and-rail, etc.).
Step 2: Check the Rules
Before your start digging, check with the local council and talk to your neighbours (especially if it’s a boundary fence), as you may need permits, there may be height limits or other regulations. In New Zealand, the Fencing Act 1978 covers cost-sharing between neighbours, so have that kōrero early if you’re planning to split the bill.
Step 3: Plan & Measure
Mark out your fence line with string and stakes. Use a tape measure to work out how long your fence will be, and don’t forget to factor in gates if you’re adding these. Double-check for underground services before you start digging (a quick call to BeforeUdig is worth it).
Step 4: Gather Tools & Materials
This is when you come and see us at Canterbury Timber & Hardware. Bring your measurements and your vision and let us calculate all the materials you will need for your fence.
We know you are going to need:
- Fence posts (H4 treated if using timber in-ground).
- Rails and palings (H3.2 for above-ground use).
- Nails or screws (galvanised or stainless steel to avoid rust).
- Post hole digger or auger.
- Level, tape measure, and hammer or drill.
- Bagged concrete for securing posts.
Optional but handy: circular saw, string line, builder’s square, gloves and “cold refreshments” 😉.
Step 5: Set Your Posts
This is the strength of your fence. Dig your holes about 600–800mm deep and the distance we have recommended. Drop in the posts, make sure they’re straight (use a level), and pour in the concrete. Let them set overnight so they’re rock-solid before attaching rails. You might find it easier to brace the rails while the concrete sets.
Step 6: Add Rails and Palings
Once the posts are sorted, attach the rails horizontally using two or three per section depending on the height of the fence. Then fix the palings vertically, starting at one end and keeping them evenly spaced. This is butting the palings. For a traditional look overlap the palings slightly. Either way use a spacer block for consistency. For a professional look, keep the tops of the palings level or follow the contour of the land.
Step 7: Finishing Touches
- Trim any uneven tops
- Add post caps or capping for extra style
- Stain or paint the fence to protect it and match your property
Final Tips
- Take your time with the post spacing and alignment.
- Get a mate to help as it’s easier with two sets of hands.
- Do a bit each day if needed, and don’t rush the concrete curing time.
