....1st pics follow....

Here is pic 1 of the covered area under zone 4

Here is pic 2 of the covered area under zone 4.
Water does pool in zone 4 (flows from zone 5)

Here is pic 3 of the covered area in zone 4

This is in zone 5/6.
Zone 5/6 has had open bags of compost leaning against it for about 10 years

This man-hole type thing is in zone 6

Oh dear, I rarely go as far as zone 7. In it I found this blocked gutter (to be fair it is hidden under a stone)

And this worm which I hope is just due to the compost bags...

The lowest brick is green the whole way along the bottom of the wall -like the very first pic on the thread.

hopefull bump.

I have noticed water dripping from upper stories and gutters on the stone-work. presumably that's a first step - to protect the brickwork.

It's from 1860 so no damp-proof layer.... although someone appears to have attempted to drill holes later on...

Picture 1 of zone 4 has a white deposit on the pipes. This is often seen where there is a leak allowing soapy water from a washing machine to escape. Is that possible?

Thank you!

Yes, more than possible.

I have spent the weekend watching youtube videos and learning about damp. What do any damp-lurkers think about this chap?
He's certainly entertaining!

grrrrr.

As I often say, chemical injections and tanking do not repair leaking pipes, drains or gutters. Damp is water and the water is always coming from somewhere. In his other vid he shows obstructed airbricks. Chemical injections don't repair them, either.

good, glad the two of you agree!

guided by old piglet john posts and these videos I spent a fair bit of the rainy weeked watching the rain fall on this part of the property. I'm fairly horrified. The walls in zone 3 in particular seem to be used in large part as a sponge.... The damp in zone 3 is worst at the top, then it's quite dry, then it's bad at the very bottom.

I'm beginning to wonder if I need a damp company that specialises in NOT installing tanking/new plaster? but instead does stuff about ventilation, ground level, getting rid of drips, maintaining the walls, etc. unfortunately that may be quite hard to find.

my next door neighbour has his bedroom in the equivalent part of his house so it must be possible to deal with this.

"does stuff about ventilation, ground level, getting rid of drips, maintaining the walls"

A local builder does all that.

With luck you will find a wrinkled one who sneers at damp-proofing ripoffs

An experienced local person (by recommendation) will have seen any number of houses like yours, built the same way in the same conditions.

Have another look at the concrete and look for cracks and patches, especially near drains. I couldn't see well in the pics where it's wet.

had the first damp company round today and they recommended a builder for the outside maintenance work and agreed that that's thing one.

They said there's no penetrating damp (the mould inside is condensation) but that all the failure to maintain the outside is creating a temperate that's lower than it needs to be and so it's creating/exacerbating the conditions in which the damp is causing trouble.

They said a lot of the trouble is lifestyle (the property is tenanted and the radiators had sheets on them).

They said the main thing we can do to improve it is a PIV ventilation systems and that's doable even whilst tenanted.

A quick thank you. Retrofitted trickle vents (more air in) and a better extractor fan with a duct to the outside have done the trick
