Why we always look for the cause first
A repair that ignores the reason the plaster failed is a repair you will pay for twice. Damp coming through a solid wall, a slow leak behind a bathroom, salts in an old chimney breast or ongoing structural movement will all destroy new plaster just as quickly as they destroyed the old.
Where the cause sits outside plastering — a roof, a gutter, a pipe — we will tell you plainly so it can be sorted before we start.
