There is a damp problem in my house for which I need advice, please.
The building was originally built in 1400s, remodelled, and extended in the 1970s. Some walls are stone and about a foot thick. Others appear to be breeze block.
The damp is appearing at the ceiling/wall join of a bedroom on the inside of a south facing rendered gable end (see photo). The prevaiing wind/rain is south westerly, so the gable end gets a lot of weather. There is a small visible horizontal crack in the render aprox 3 feet below the site of the damp.
The damp on the inside walls corresponds more or less to the darker areas of ?mould? on the gable end render.
I had a builder visit, and his solution was to fill the cracks with silicon, paint the gable end with Sovereign Facade Cream and replace the cement fillet (see photo) with leading. (See his quote below)
Filling the crack with silicon and painting the whole with a waterproofer seems to me to be a bodge solution, but what do I know? I'm only a yacht skipper by trade.
Can anyone offer any advice please? I don't know my base from my apex on these kinds of things.

Builder's solution:
Cement fillet may have cracked between no 4 and no 5, we would suggest removing and replacing with new lead flashing £1695.00
Seal any cracks and apply coat of Soveriegn Façade cream (water proof) £795.00
Alternative: Apply Parex coloured through render to gable end south facing instead of façade cream £1495.00
Erect scaffold for remedial works to gable end
£1245.00
Silcon fill cracks to front elevation, apply Soveriegn façade cream £865.00
Paint front masonary walls with exterior masonary paint to your colour choice £537.00
