What Materials Do I Need to Fit a Fence?

There are several materials required, but if you're not confident in doing the job, you can hire someone who is already experienced in installing fencing and gates. However, if you are going DIY, then below is a list of the items you will need to carry out the work successfully:

  • Fence posts
  • Fencing panels
  • Fence clips
  • Screws
  • Nails
  • Wood to make temporary support
  • Cement and aggregates or post cement
  • Water for mixing cement
  • Sealant
  • Fence post caps
  • Wood preservative

How to Prepare for Fitting a Fence

To prepare for building your fence, you want to begin by removing any small plants that may get flattened in the process. Transfer these small plants into temporary pots and move them away from the work area. These can then be re-planted in place after the fence has been erected.

The best time to erect a new fence is in autumn or in early spring when plants are at their lowest heights or aren't blooming just yet. You should also discuss your fencing plans with your neighbours as a form of good common courtesy.

Ensure the posts are made from wood treated to Use Class 4 (UC4). If you have to cut the post to size, make sure the cut end is at the top and not in the ground, and apply two coats of end-grain preservative onto the cut end.

Fitting a new fence in your garden is ideally a two-person job, so you should find someone to help you with it before you attempt to take on the job yourself.

How to Fit a Fence Yourself — Step-by-Step Guide

Step 1

Lay out a straight line of string to mark out where your fence panels are going to go. Then, use tall bamboo canes to mark out where your posts are going to go.

This is so that you can see exactly what needs to go where and so that you have a guide to work around. Make sure that your post markings are measured to the length of your fencing panels so that you can ensure that you dig at the correct location for each post.

Step 2

Dig out the ground down to 450mm for each post for a fence up to 1.2m tall, or 600mm to 750mm for fences up to 1.8m tall. This is a standard depth for most fence panels, although on softer ground you may need to dig deeper and use a longer post.

Step 3

Aim to insert your posts at both ends first before doing the middle posts. Insert your posts into the holes you dug. You should then run a piece of string tightly along the tops of the posts as a guide for the rest of the posts to make sure that they are level. You should also check that your posts are completely upright using a spirit level on all sides.

Step 4

Once you're happy that the post is at the right level and completely upright, hammer in some pegs at the bottom to temporarily hold it in place.

Step 5

After all the posts are in place, check they are standing upright by using a spirit level and that they are all aligned with your guide string. When you're happy they're all correct, ensure the pegs are secure to help prevent any movement.

Step 6

Attach the fencing clips to each post on both sides, 150mm from the top and bottom of where each panel will sit.

Step 7

Slide your fence panels in using the fencing clips as your guide.

Step 8

Before fixing your fencing panels in place, you want to raise them at least 50mm away from the ground, so they don't rot.

Step 9

You now need to cement your posts in place. We recommend using fast-setting cement so that you don't have to stand holding the posts in place for hours on end. This process can cause a lot of dust so ensure you wear eye protection and a face mask for this part of the job. Begin by double-checking that everything is in line and in the right place before you cement the posts.

Step 10

If you are using a ready-mixed post-setting concrete, then half fill the post hole with water and add post mixture evenly to cover the water. Don't mix, but sprinkle some water on remaining dry powder if needed. It starts to cure within a minute or two, so ensure the post is level as you add the mix.

Traditional cement, sand, and gravel should be mixed together before adding water to create a consistent mixture. Continue to fill the post hole until it reaches the top. Remember that your fence panels should be raised, so the concrete shouldn't reach the fence panels.

Step 11

Allow the concrete to dry slightly and then trowel some of the mixture upwards towards the post to create a slope. This is so that water runs away from the posts and they won't rot.

Step 12

Add post caps to the top of the posts if desired. Do this by adding sealant to the underneath of the cap and then placing it on top of the post where it can then be screwed into place.

FAQs

How Many Fence Panels Will I Need?

The number of fence panels you need will depend on the length of the space you are fencing and the length of your panels. Measure the distance from one end of where the fence needs to go to the other end, and then also measure your fence panels. Also take into consideration the size of the fence posts (typically 75 to 100mm each), and you should then be able to work out the number of fence panels needed.

What Type of Fence Post Is Best?

Most fence posts are made from either concrete or wood. They both have their advantages. However, many people prefer wood fence posts due to their versatility. If you do choose wooden fence posts though, you must make sure they are treated to Use Class 4 before being installed.

How High Can a Fence Be Without Planning Permission?

Planning permission is only usually required in England and Wales if your fence is higher than 2 metres, or 1 metre if your property is next to a public road or its pavement. Fences of any height around listed buildings, bordering neighbouring listed buildings, or on properties subject to an article 4 direction require planning permission regardless of their height. Rules vary in Scotland and Northern Ireland.

What Causes Swelling and Shrinkage?

Timber naturally absorbs and releases moisture depending on the surrounding conditions. It shrinks as it dries, as the outer layers lose moisture faster than the inner core, causing the wood to contract, which can sometimes lead to splitting or warping.

Why Is There a Variation in Colour on My Fence Panels?

Every tree is different, and even after treatment, the wood can appear to look different or may appear to be different shades. Colour differences will become less prominent over time. However, it's not possible to get a consistent colour of fence panels due to their natural differences.
