Joist screws

[Sam189]

My parents house, loft conversion done in the 1970s by a respected local builder, hangers nailed with 3 x galvanised plasterboard nails (before they invented fancy plasterboard screws) per hanger - still standing and us kids gave it plenty of punishment over the years.

I was quite amazed when I pulled up the floor, but I had bigger fish to fry so just left them alone.

However, it's fairly basic to use those fat twist nails these days so I'd question where else he's cut corners.

I have changed builder now, but it was playing on my mind. I just wasn't sure if i needed to change them all or if they were safe to leave. Ive had some good advice on this forum. Thanks for the advice

Great, wasn't really advice, just general reassurance that they'd probably be ok - you'd get plenty of warning of a problem before catastrophic failure.

This is how I do mine:

I cant believe how stressful building work is

If you follow your builder round with Dr Google and the wisdom of a thousand armchair warriors, I'm not surprised you find it thus

I am a single parent mother to 4 children, 2 have a disability so I just want things to be safe

I understand your concern; I'm the same with mine, but this level of intensity will make life far harder than it needs to be

Yeah I don't think it's 'unsafe' necessarily but because spax screws don't have a rated shear capacity the connection has an unknown load capacity.

If you do want reassurance you could add some skew nails at the joist ends


I should be surprised at Building Controls attitude but unfortunately I am not.
