Hi you would need to get a plasterer to apply storm dry damp proofing to the bricks on the external wall hack off down to original block or stonework internal apply sika internal waterproof cream let dry do new scrach coat then skim over it.... also if you got a window near the damp are check lintle and check if there's a dpm tray above it with weep vents coming out so it let's the water out of the cavity

First, a bit more info required !!  
Is it an external wall ? And is it a solid 9'' wall?  If so, it seems like the damp proof has failed. A specialist firm can inject a new silicon damp along the water line or if you're adapt there are kits available on Amazon! Drill holes and inject with the liquid silicon. The cause must be dealt with before sorting the cosmetic bits, which would need exposing all damp areas and allowing to dry. wire brush all flaky areas and seal with a waterproof sealer, replaster and paint. Feel free to repost question if more info available.
I hope this helps.

A general builder will be able to do this, they should have the skills to resolve and to a finish you require

Floyd · Answer

Those sodden bricks would need to be replaced. Examining if the exterior brickwork and/or mortar has been compromised and repair where necessary.
Waterproof the exterior brickwork once secured. Then plaster the interior and treat with anti mould primmer before painting or wallpapering.

Hi the solution to the black marks and damp is caused by the failure in the pointing work on the exterior bricks which causes rising and internal damp the only way to fix the problem is to have the old pointing grinded out to a minimum  depth and repoint the area then applying a liquid waterproof solution to the outside brickwork to prevent further water damage that will last years minimum if done correctly my company specialises in this kind of repairs daily Regards Jason

You would need to hire a bricklayer or a plasterer to address the issue of the black damp bricks on your interior living room wall. They can assess the situation, recommend the appropriate treatment, and carry out the necessary repairs to resolve the problem effectively. It's essential to have a professional handle this to ensure the work is done correctly and to prevent any further issues with dampness.
