Damp on outside wall

Have you checked in the loft to see if there's any evidence at all of a leak from the roof?  If it's visible outside then I'd say its getting a soaking somewhere and more than just a ventilation issue.  

I'm in absolute with freebear.  You need to remove that concrete from the side passage.  Someone did it properly initially and laid the paving away from the wall and then someone else has come along and put that concrete in. 

The damp proof course is being breached, it isn't 'failing'.   I don't think that is the only issue though. 

The roofer did and he said it was leaking inside. He showed me pictures of wet timber but when I’ve gone up and I couldn’t find damp timber. Roofer also said the chimney needed re-pointing. 

I got a guy a few months ago to paint some waterproof paint on the stack (yes I was silly) and it helped stop the water ingress, but not 100%. The flashing could have let in the leak?

It's not showing at ground floor because someone has "treated" this long ongoing issue by installing a chemical damp proof course at ground level.  That involves putting a waterproof render on your ground floor walls.  It hasn't solved the problem, it's hiding some of the symptoms from appearing inside on the ground floor.  It will start to reappear above the 1m mark on the ground floor. 

Yet another example of these snake oil salesmen.  

You have got a significant issue with rainwater leakage and painting stuff more recently was never going to be any kind of effective protection against the rain.  

You need a decent roofer up there and to be prepared to spend some proper money.  You are in serious danger of there being rot in your roofing timbers.  This needs sorting out now.  

Replace the entire roof covering if needed.  

I’ve removed the stack, what else can I do?

Are you sure it is brick ?

It is more likely terracotta quarry tiles - Bricks laid as a floor would be, um, agricultural at best, and not what I would expect in the vast majority of houses. If you do have an original quarry tile floor, it would be worth repairing and conserving. A period feature like that has been ripped out of so many houses...

It’s a solid floor

Fix the roof! 

Removing a chimney stack is the most bizarre answer for a considerable roof leak that I've heard. 

Installing a chemical injection at ground floor for a roof leak is the second.  Painting it with 'waterproof paint' is the third.  

Stop surrounding yourself with cowboys and fix the roof.  It is leaking.    

Replace the whole thing if you have to.  That would have done the job the first time.

Hi I think you misunderstood. 

I was obviously unknowledgeable when I got the guy to use the water proof paint on the stack. The stack is now gone. I got rid of the stack because it required work doing (flashing and repointing) and I was hoping that was causing the damp wall (it’s in a first floor bedroom and only around that chimney). 

I’ve been in the loft, it looks fine. I can’t find any daylight or wet areas. So why would I replace the whole loft?

Roof* not loft

You've got water coning from above somewhere.  Someone needs to find it.  If you can't find it then I'd be inclined to recover it because a stitch in time saves nine and you're probably already at four or five.  And surrounded by people who appear to not know what they are doing.  Taking the stack down, to me, shows a lack of integrity in attempting to find shortcuts.  

Taking the stack down involves a certain element of re-roofing in the first place.   Depending on the roof covering, it might not be possible to do that without a bit of a knock-on effect, like with old slate roofs. You fix one bit and there's a ripple that follows out from the disruption.   

Whoever paid for the DPC could have done the chimney and roof properly with the same money.

And why do you think the roof leak isn’t caused by the need for the stack to be repointed and poor flashing?

There don’t appear to be bricks below the concrete?

The area needs repointing?
