And yet.... and yet... houses do get built. I think this thread is another data point underscoring the aphorism that; Systems and people show themselves for what they really are when -not if- things go wrong

Now thats both interesting and reassuring.

Ooooofffff, when I tried that, our builders ducked and dived, bobbed and weaved. Took me ages to learn the lesson. And just a little longer to sack them.

Thats how we found out that the guy who set out our plot made a one meter error. So I paid him £1 less than he charged. (But bought him a pint in the pub)

Here Be Dragons. For me, that's a Red Flag.

Air test, leaf blower... erm, how? And how half-arsed ?

Dave .... be kind ... @Lincolnshire Ian wrote ' ... Our council will start charging us council tax ...' Ian: the answer is No.

That's it..... I knew that necking is the precursor to fracture. My mum did warn me.

Is that a 'General Rule' ? Snug fit , plus a quarter turn ?

Ah, thanks. If (like me) you don't know what to search for - or indeed if a topic is searchable - you can't find it. So just in case anyone is researching the same topic - - the seach term I used is bolt tightening torque calculator And here's the result. There are also downloadable apps that do the same thing ( but better?) Well I never. Who knew?

OK, so I've bought my wrench. How tight should I set it ? Where do I get guidance for all those hundreds of times we've all tightened ( over-tightened) bolts?

But its comforting to over-tighten them. In the context of bolts and threads (and without a torque wrench) - how does a self builder (or indeed anyone) know what's too loose and what's too tight ?

What's 'High Specification ’ ? What she says is....

I'd use leftover walk-on glazing....

Could I respectfully ask @zoothorn , have you done a Heat Loss Calculation for your house? Perhaps you have and I've overlooked your reply. If you have, would you mind sharing it with us please.
