Damp patches on wall - what to do?

[mamabluestar]

For context I've been in my terraced house for 16 years.

I've noticed 2 damp patches appearing on my front interior wall, between the window and front door. Upon closely looking at the exterior pebble dashed wall I can see that there are 3 holes in the wall (which I presume were for a hanging basket bracket from years ago) - could this be leading to water ingress? Either way please can anyone advise on the course of action I need to take?

It's the sort of thing my Dad would help me with; but he sadly passed away in September and feeling clueless without him 😔

How big are the damp patches? I’m wondering how 3 little screw holes could allow so much damp, we’ve taken basket brackets down from our brickwork and haven’t -touch wood!-had an issue. What is the guttering like above the patches? Is there a down pipe in the vicinity?

maybe if you post some internal and external pictures @PigletJohn could have a look?

I’m sorry for your loss

Just to say I've been in my house for 4yrs and the sudden damp patches that have appeared in the past few weeks are quite something.

I do hope you can find a fix and will shamelessly follow this post!

So very sorry about your loss
