The problem
Blown plaster can't be patched over. It needs removing.
Victorian and Edwardian properties across Middlesex and the Home Counties have lime-based plaster applied directly to solid brick. When damp gets in — through an external defect or poor ventilation — the bond between plaster and wall breaks down. The plaster blows.
Skimming over blown plaster doesn't fix it. The hollow sound test will find it, and the skim will crack along the same lines. The answer is to remove the failed material and replaster.
The Hancock approach
Remove, prepare, replaster. In that order.
We knock out all failed material, establish what caused the failure (if not already diagnosed), and treat the substrate accordingly. On solid brick, we assess whether lime-compatible materials are needed or whether modern gypsum plaster is appropriate.
Cornicing, dado rails, and period features can often be retained and reinstated during refurbishment. We assess on site and advise on what's salvageable.
