securing deck to house

[EJ999]

Hi I have brought an old house and the rear deck to the second level appears to not be attached well. Nailed plank. I want to fix it add a new ledgerboard but am not sure what size dyno bolts to use? Any help please. Thank you from Emma

Hi @EJ999,

A warm welcome to the Bunnings Workshop community, it is fantastic to have you with us.

If this is the only way the joists are supported, then I would strongly suggest you do not stand under this deck and have it assessed by a licenced builder immediately because this is not a safe, structurally sound method of supporting a deck.

In saying this, I don't think this timber is supporting the joists as it looks like the joists extend past the timber and sit on the block wall behind. 

Can you see the timbers from the other side of this wall? If so, what can you see? Do they sit on the wall?

If they sit on the wall, I am not sure what function this timber is serving, but it is not supporting the joists.

Allow me to tag @Dave-1 and @Nailbag for their thoughts.

Good Evening @EJ999 

I was wondering why you needed a new legerboard at first, Then read @JacobZ 's words and zoomed in.

Is the bessa block a double brick wall?

Are those beams sitting on the bricks or on that timber bolted to the side of the wall?

Your beams kind of look like they are sitting on the timber which is bolted to the side of the bessa blockwork and that timber is also bowed to a large degree? I would be cautious adding anything to the bessa blocks until you have it assesed by a licenced builder. Is the other side the same? And do those beams go through the bessa blocks?

Hi @EJ999 

On the surface of the phot the deck appears to be well built though light on support.Its hard to tell, but f the large beam extend within the brickwork, then structurally the deck should be sound.

But if it's the horizontal timber being the only support, then yes that needs to be supported as per @JacobZ concern. There are a few methods to easily secure the beams, but being a newbie DIY'r My preference would be to get in touch with a local registered builder. I don't think it will be an expensive fix at all, but one that needs to be handled by someone qualified.
