How can I get the right advice and solution re damp and mould?

[Sidebeforeself]

I need your collective advice please on which “tradesperson” I should engage with to resolve my problem.

I have mould occurring in my flat . In my bedroom and en-suite, on the walls and around the windows. I have invested in dehumidifiers and keep on top of cleaning. The room is well heated too.

I am convinced the source of the problem is that the exterior need re pointing.However, my concern is that if I say that to a builder ,they’ll just agree because its a big job and probably £££. I dont mind paying as long as its a solution.

I dont know any builders so I’d have to shop around.

What I really feel I need is someone to give me an honest assessment ,one that they wouldnt necessarily profit from.But if I go to a damp//mould specialist they all seem to want to sell damp proofing etc.

Can anyone suggest which sort of service I should be looking for. Just to be clear, I expect to pay for their service and advice..what Im saying is Im not sure a builder is the right expert.

If the damp if low down then it could be because the concrete around the building is breaching the original slate damp proof course? How close is the concrete to the bottom of your external doorframes? It should be 2 or 3 rows of bringlcks lower at least.

The damp seems to be in various places.

So the en-suite its at the bottom of the wall near the toilet pipe and on the side of the window.
In our bedroom, it’s in the corner of the exterior wall and is both coming down from the top of the ceiling and up from the skirting board. It’s also around the windows.
I can also see staining about 6 inches on the back wall of our bedroom although thats not black mould, just looks like a brown mark.

So it seems to be the two exterior walls our our bedroom and en-suite.

Yes

The pointing isn't bad. Nice quality bricks and unless the house is very old they will be bedded in cement mortar anyway.

I also don't like the look of the injection.

Something strange has happened to the brickwork just below the roofline. I don't like the look of it. Borrow some binoculars for a closer look.

There is a green mark on the paving concrete. Please stand back and take some wider pics showing the extent of the green and damp, and what is above it, for example a gutter or overflow pipe.

Take some pics of the gutters, downpipes and gullies.

The verge of the gable wall needs renewing, depending on wind direction, water might come off the side of the roof. There are some bricks near the top of that wall looking wet damaged.

Brown mark staining is often associated with damp in an old chimney, as the water dissolves soot and tar as it passes through.

It can also be from old wood, but that's more common with a leak on a ceiling.

"So the en-suite its at the bottom of the wall near the toilet pipe and on the side of the window."

Those could both be due to leaks. Please post pics.

"it’s in the corner of the exterior wall and is both coming down from the top of the ceiling and up from the skirting board"

That might be a gutter leaking. Pics again please.

Thanks so much . I will post again on Friday as Im away now until then.

The brown mark staining is on the back wall of our bedroom ( thats the same wall as the one in the pic with the roofline). So no chimney there .

I should add we’ve had the gutters cleared too.

I do appreciate your help @PigletJohn

At the corner of a house, each gutter has either a corner joiner, or a stop end. They have a joint that can come loose or leak. Sometimes they hang off. Sometimes the gutter sags or does not slope correctly.

Not sure how long they last. 30 or 40 years perhaps?

I made gallows brackets to support the ends of my gutters where they projected beyond the last bracket.
