Condensation

[mikeey84]

Just removed some boxing around pipes, expecting to find a leak (creeping yellow stain on wall and ceiling nearby).

Instead I think I have a condensation issue. Cold water pipe, very wet to touch (in same room as tumble dryer)

It's very awkward to get too, so lagging effectively is not possible.

Could I fill the box with expanding foam to insulate the pipes from the warm, wet air?

Obviously once I'm 100% sure it isn't a leak!

yes. bear in mind the foam may destroy the box.

Thanks. Turns out it was a leak....

lucky you didn’t fill the box then

That escalated quickly

Wasn't feeling very lucky!

Laths and plaster were so soft they just fell down when I poked them.

Just wish I'd checked before I boarded the ceiling...

As my wife often tells me, be careful what you go around poking, you can never be sure of the consequences

Haha, sounds like our wives are very similar.

She did ask whether I could have just left it.

I explained that rotten joists under baths were probably not a great idea...
