Joist hangers not great.

[John2000]

Hello, the builder here has gone a bit well… I don’t know without being rude. 

He’s done a really good job throughout but let us down on these bits which are the joist hangers. One is a car crash which he said he let his labourer loose and is going to change. The other 3 are partially nailed. (One folded down at top but on a double for stair opening. The others on a single but just down one side or holes omitted. My BCO suggested extra nailing from joist direct to ledger but really should I be getting him to cut off bolts and re fit where I can? (The car crash one he will) the one with hanger bent down at top could be enhanced nailed direct into ledger? - although it’s on a double for stairs. The one that is only down one side is also not great but only on a single, as his the partially, they’re both nailed in top though so I thought the one jumping the patted plate is ok. The half side only - I don’t know. Any practical suggestions to get these fixed please?

Pictures?

 

Doesn't building regs say to nail in every hole?

Theirs a nailing schedule on the hanger. I.e 20 for face fix only. 8 for face and 4 top. The schedule doesn’t give a mix though although their are others ways around apparently without hangers but needed to know the best alternatives

The car crash one is an important one as it’s a double joist. 
get him to install a bolt in the wall in the right bloody location 🤦🏻‍♂️

then sink the nuts in on the wonky ones so they are flush, then re fit the joist hangers correctly 

Fark me it’s not that hard. 
 

why are the bolts at a stupid angle. 

[John2000]

I assume he let the labourer loose. I wasn’t impressed. He’s back next week to sort them out. I didn’t think about recessing the nuts in. Theirs another that’s nailed one side that’s again (near the pipework) some wierd F’ing situation that could’ve been avoided but it is partially nailed on top though. It’s just annoying and lucky I’m on top of the checks before I dragged BCO out only to fail it. Rest of the work is spot on or even overkill. Doesn’t add up. 3/4 money held back though until sorted.

Count yourself lucky. I found this beauty on the entrance to my new upstairs bedroom.

There's nothing in that last picture to indicate how the ledger board is bolted to the wall at that point. The last fixing could be some distance away on the right leaving that corner poorly supported. Do you have a design showing how this is supposed to be installed? I wonder if the ledger has been cut around the pipework.

I guess this is because they knocked a hole in the wall to install a padstone and the wall next to it wasn't intact enough to fix into.

 

The washers used on those wall bolts don't look that large or substantial to me. If you tighten a bolt with a socket does the bolt and washer pull through into the timber? If so then I don't think it's doing it's job

I think that will be a struggle now the joists are fitted.  You would need to unbolt and remove the ledger which may not be practical.

Just drill new bolts a couple of inches away, and grind off the ones in the way. 

 

No need to remove the ledger if it’s level and other fixings are kosher?

 

Plus one on the washers being too small. They have just been wound into the treated wood which is soft and won’t give much purchase. Should be big square washers afaik.

[Roger440]

The big square washers was my understanding (and what i used).

 

Obviously to prevent the nut being pulled into the wood, either by overtightening, or to stop it becoming detached.

Was that really new work done recently?

 

It's a LONG time since I have seen joists fitted without joist hangers.  Not since I was a boy playing on building sites at weekends (as you did then before elf and safety) and I remember thinking even then, gosh is 3 nails banged into the end grain all that is supporting that joist.  And back then, it was.

builders "finished" in 2023. Then i spent a good 6 months working through the snags they left behind. Most joists are in pockets but there were a few like in the photo.
