How to repair a rotting fence post?

Hi Team

I have a 1 fence post leaning towards back intially due to strong wind and rotten. Now I check, it is leaning towards front.

Just wondering if reinforcement will help straighten the post as it is too costly to change the whole fence. At least it can last for another few more years.

1. Can someone please advise what reinforcement , and other tools should I purchase?

2. Also should I install 1 or 2 reinforcement ?

3. Should the reinforcement be installed at the front or 1 side or both side.

Im hoping to get it repaired before the next storm.

See attached some photos

Also, note that there is another post which is still in tact , having an existing enforcement as per photo.

Looking forward to hearing from an expert.

Many thanks

Thierry

It looks like it's time for a new post there @Thierry. The cost for the post is likely not a whole heap more than what it would cost for the two post supports you'll need to fix the situation temporarily.

A couple of Whites 165cm Premium Black Ultraposts should be enough on the property side of the fence. Drive them nice and deep into the ground right next to where the fence post should be. Create a bit of a pulley system with some rope and host the fence back into position. Drive some coach bolts through the holes in the steel posts and into the timber post. That should hold the fence in place, albeit temporarily.

Please let me know if you have any questions.

Hi Mitchell

So 1 " Whites 165cm Premium Black Ultraposts" is enough to be installed at only 1 side of the post fence?

Also i notice the "Whites 165cm Premium Black Ultraposts" is not wide, so no need to remove any fence to set it up

Thanks

I'd suggest using two of those Ultraposts on the property side just to be safe @Thierry. No need to remove any fence, just drive them nice and close to the fence posts base and perpendicular to the ground.

How deep should the post be underground?

I saw this "FPBM44E 90mm Fence Post Repair and Reinforcement E-Z Mender"

How would you compare it to your suggestion?

Can u suggest a hammer?

Thanks

You could do a combo, one of each @Thierry. I like the look of the E-Z Mender, but a long post that can attach higher up your timber post has the benefit of leverage when trying to hold the weight of the fence. If you can get the fence back in line and then drive in the E-Z Menders in on either side, they could have a good chance of working.

You'll want to drive the Ultrapost in as deep as possible, and I'd suggest a 1.8kg or, better still, a 3.6kg sledge hammer. Try for at least 600mm in the ground.

Hi Mitchell

The leaning post is quite loose, i can straighten it up with one hand...

My plan, get someone to straighten the fence for me, while i dig in the ultrapost in - as this is your preferred option -: the ultrapost willl give a better result

Hi Mitchell

I just bought the "Whites 165cm Premium Black Ultraposts"

I notice my post fence height is 155cm.

1. The 165cm ultrapost when digged down will appear to be lower than the fence height, will it still be ok?

2. Do i need to predrill the fence post before screwing the bolts?

3. What size bolts do you recommend given the width of fence is 7cm?

I tried to do a test with the roofing screws i already have but they have got a stopper which prevent the screw from going any further inside

Also, what

Having the post less than the height of the fence is fine @Thierry. I'd suggest using Zenith M6 x 65mm Hot Dipped Galvanised Hex Head Coach Screws, and you'll need to pre-drill first with a Sutton Tools 4mm Viper Jobber Drill Bit.

Please let me know if you have further questions.

I'd suggest four screws @Thierry. You can use an adjustable spanner to tighten them or a socket set.

Hi Mitchell

As suggested, I was tightening the screw with an adjustable spanner and screw broke.

Now when I try to drill another hole, that drill bit also broke.

I think the drill bit and screw not strong enough. Will I get a refund for the broken ones?

Please advise how how to screw them now.

Thanks

Hi @Thierry,

It appears as if you have some really solid hardwood posts there. I'm not sure why the drill bit would have broken, though, as it's designed to drill into steel.

Did you pre-drill the holes to a depth suitable to accept the entire length of the coach screw? If the holes were not as deep as the screw, the screw likely bottomed out before being fully screwed in. It then snapped the head off as there was no more hole to screw into.

You can certainly speak with the team in-store about a refund, as it looks like this method hasn't worked out for you. If the holes were drilled to the correct depth to accept the screw, then the only thing else I could advise would be to try a 4.5mm or 5mm drill bit. The 4mm bit you were using should have been adequate for a 6mm screw. If the post is really tough hardwood, the larger drillbit could be required. Remember that we can't go too large, or the coach screw won't screw in.

If the coach screw doesn't relatively easily screw in, you need to stop and re-assess. If you forcibly screw it in, it'll snap the head off.

Please let me know if you have any difficulties exchanging your items.

Hi Mitchell

As advised, i bought the 4.5mm drill bit.. holes drilled successfully.

One head got snapped off again..

2 others cannot screwed further... Im hoping to keep these 2 screws only.. just scared if i screw further the head might break... I removed the screws and re drilled a bit further..

Still not in completely

see photos..

@Thierry,

Can you confirm that the depth of the hole you are drilling is the same length or greater than the length of the screw? Two partially installed screws should do a reasonable job of securing the post.
