I need to repaint some ceilings in my flat that have suffered water damage from a leaking roof terrace up above. The whole ceiling was completely rebuilt, insulated, new plaster board and plaster and decorated around 5 years ago but the problem has persisted and the ceiling is full of stains again. I need an expert who can advise the best way to decorate to fully eliminate the stains. The roof terrace is due to be completely recovered at the end of August and I am looking to decorate my flat soon after. Does anyone know any good painter decorators in the area- Sydenham, Dulwich, forest Hill etc
