Watch the video and follow the steps below for instructions on how to construct a picket fence.
First, remember to check your boundaries. You should also contact your local council to find out about building regulations in your area you may require a permit.
Before you begin, work out where your end, corner and line posts need to be situated and mark them with stakes. Tie a length of string between each post to get an idea of your space.
Next, dig a hole for each post that's about half a metre (50cm) deep. It's a good idea to make your holes about double the width of your posts to allow for adjustments. To avoid your post rotting prematurely, cut the top of your posts at a slight angle to allow water to flow off. Or, you could choose to cap your posts.
It's easiest to install your end post first, followed by your line posts, which should be spaced evenly at approximately two metre intervals. Before you concrete your posts into position, add around 50mm of gravel to the bottom of each hole. Make sure each post is plumb, then pour in your concrete. Line posts can be set the same way as your end posts.
The next step is to measure and cut the rails to size to fit between the posts. Remember measure twice, cut once. You'll also need to work out how many pickets you need. To save time, paint or stain your posts, rails and pickets before you assemble your fence.
Fasten your rails to your posts using galvanised nails. The bottom rail should be around 150mm from the bottom of your posts, while the top rail should be about 50mm from the top of your posts. For extra strength, you may choose to check the rails into the posts using a housing joint. Simply measure the height and the width of your rails, cut into your posts with a handsaw or power saw and chisel out the middle.
Next, measure where each of the pickets should go along the length of your rails at even intervals, and mark with a pencil line.
Top tip: use a small block of wood as a spacer to ensure all your pickets are spaced evenly. Nail each picket to the rails, and there you have it a perfect picket fence.
