How to add a timber fence extension?

Hi,

I have a post and rail timber fence and just purchased the 2400mm treated pine extensions. I did watch the installation video on your web site but did not pay attention to the fact that the fence shown in the video did not have the top rail installed. My top is to wide to slip the fence extension over and I do have the rails on my side of the fence and cannot access it from the more flatter other side.

How can I fasten the extension on my side so that it is nice and sturdy and does not wobble?

Thank you for looking into this.

Hi @Evie21

Are these the extensions you're referring to?

Hello @Evie21

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thank you for sharing your question about your timber fence extension.

Before I make any recommendations, I just wanted to confirm that it is the Lattice Makers 2400 x 500mm Paling Fence Extension that you purchased for your fence extension? If it is, you can still mount it onto your fence, but you'll need to add additional bracing timber or post extension such as the 70 x 35mm L/M Outdoor Framing MGP10 H3 Treated Pine.

Unfortunately, this fence extension kit is built to slide into single panel fencing with no timber fence cap. The extended legs will have to be cut off so that you can mount them directly onto the post extensions. I've placed an example of how the extension can be installed, please let me know what you think.

Let me call on our experienced members @Adam_W @TedBear and @diy_hausdesigns for their recommendations.

Please keep us updated with your progress, we look forward to seeing your fence extensions installed.

These are the extenders https://www.bunnings.com.au/lattice-makers-2400-x-500mm-paling-fence-extension_p0189433

I thought of sawing the legs of one side and just fastening the other side to the horizontal rail.

If I need more strengthening I could pack up behind the legs and fasten to the actual fence slats a bit more. Also the lady I. Bunnings recommended to join each panel to each other on the top. That hopefully should be strong enough?

Hi @Evie21

Thanks for letting us know how you plan to proceed. Please just keep in mind that should you need to reinforce the fence extension to use treated timber H3 so that they will be protected from the elements and insect attacks.

If you have any other questions we can help with, please let us know.

Hi EricL

I'm pleased to advise that the panels are staying up nice and strong with 2 screws in each of the legs and then joining the panels at the top to each other.

The only problem was the poor finish on the panels and we put more screws in where they were just nailed together.

So far 3 out of 6 panels are up. We will trim the legs to the height of the top rail.

Thanks everybody for your advise and help.

Hi @Evie21

Thank you very much for that update. Those fence extensions look very good, I'm glad you found a method of screwing them into place. I'm sure our members who are in the same situation will find your project very useful.

We look forward to seeing your next project.

@EricL thanks for the nice demonstration.

however I need to add the similar extender I'm standing on the paling side. It's a lap & cap timber boundary fence. Attaching the legs to the poster seems hard in my yard. Can you please give an example for my case? thanks!

Hello @fishwh08

Welcome to the Bunnings Workshop community. It's sensational to have you join us.

Would it be possible for you to post a photo of the fence on your side? I don't want to make any assumptions regarding how your fence is constructed. But once I see what the fence looks like, I'll be able to offer you recommendations on how you can mount the fence extension.

If you need a hand posting the photos, please let me know.

Hello @fishwh08

Thank you for posting the pictures of your fence. I can suggest two possible ways that you can attach the extension. First is to pad the uneven part of the fence so that the timber post of the extension fence can be anchored to a flat surface. The second method is to cut a small channel in the timber cap of the fence to allow the post to be mounted again on a flat surface.

Please give me some time to draw up the fence example and as soon as I finish, I'll post it here.

If you have any other questions we can help with, please let us know.

Hello @fishwh08

I've placed the fence extension mounting images below. You'll see the extra panel I've placed in front of the paling so that the extension mounting post is mounted on a flat surface. The fence extension will need to be cut a little bit to make way for the post and will allow the extension to sit flat on the top of the fence. The fence extension will need to be modified when the final panel is placed at the end of the fence. It needs to be cut down and re-assembled so that it sits in line with the fence.

The fence extension is 460mm in height and you'll need to decide if this is enough to make your fence tall enough. If it needs to be taller, I suggest engaging the services of a professional fence installer. Please note that the images below are for reference only and are not to scale.

If you have any other questions we can help with, please let us know.
