Peeling paint- damp? What to do?

[JuniorMint]

Please no judgement. I have these two patches of peeling paint. In my kitchen. The one that is low down near the skirting board has a radiator through the other side of the wall. The other patch has a downstairs loo the other side of the wall, but none of the pipes etc are on that wall. What do I need to do? Scrape the peeling paint off? Do something to treat the wall? Do I need to repaint the whole room or will I be able to scrape and repaint just that section?
Will I need an expert to come out an sort it and of so who? A plumber? Handyman etc?
I have absolutely no clue what I’m doing so please explain like I’m 5. I really want to get it sorted.

You need @PigletJohn

Ooh is PigletJohn the expert?

1. do not allow anyone who sells silicone injections into your house

2. it's quite likely a water leak. stand back and take a picture of the whole wall, including all the damp as well as the dry. if not obvious, mark the borders of the wet. for small pics, include something to show scale. if you use chalk or pencil you will see if it gets bigger and smaller, useful if it is relates to rain or bathroom use (probably not, in your case). what is above? how near is the sink, bath, washer, boiler etc? how old is the house? does your boiler have a pressure gauge?

3. is it a concrete floor? pull back the carpet and see how wet the floor is.

House is around 60 years old, ex-council house. These two patches are in two separate walls. Not near the boiler, which is upstairs in a bedroom. In the kitchen but at the opposite side to kitchen sink etc. One patch has a radiator on the other side from it, I have that radiator switched off. The other patch has downstairs loo on the other side, but not the same wall that the loo or sink are on. The floor is covered with sort of fake wood floorboards (laminate?).

This is likely to be condensation. Both rooms are susceptible to it. I use an electrical dehumidifier on a regular basis. Problem solved.😉

Thank you, so to fix the unsightly peeling- scrape it off and repaint the patches? Repaint whole room? Then use dehumidifier regularly to prevent it returning?

Oops sorry didn’t notice my name had change 😊

I don't think it is condensation. please show photos of the whole wall.

under the ornamental laminate will be a floor that is either wood or concrete. I suspect concrete. what are the other ground floors made of? Do you have airbricks just above ground level on the external walls?

with practice you can tell the difference by hitting the floor, or jumping on it.
