Why lime is found in older London homes
Many Victorian and Georgian properties were built with solid walls and traditional finishes. Lime plaster and lime render were common choices, and original lath-and-lime ceilings may still be present behind later repairs. These materials behave differently from modern gypsum plaster, so a repair needs to take the existing wall into account.
Lime is often described as breathable because it can allow moisture vapour to move through the finish. That does not make it a cure for damp. A leak, raised moisture or a previous incompatible repair still needs to be understood, and the source should be addressed before a surface is closed up.
Start by checking the existing finish
A useful assessment looks at whether the plaster is firmly attached, where cracks have formed, and whether earlier work has been patched with a different material. A small loose area may need a local repair; wider failure or movement may call for a broader plan. The right scope depends on what is actually there, not simply the age of the house.
Original cornices, picture rails, timber laths and other period details can affect how work is approached. If a ceiling is sagging or a crack is changing, mention that when arranging a visit. Any leak or structural movement should be dealt with before new plaster is applied.
Lime plaster and lime render repairs
Lime plastering in London can include patch repairs, compatible finishing work and repairs to original lath and lime where the substrate allows. Outside, lime render may be considered for a suitable wall. The mix, preparation and finish need to suit the existing construction, exposure and condition of the property.
It is not always necessary to remove every old layer. Retaining sound original material can be preferable to stripping it out, while loose or unsuitable areas need proper attention. The visit is where the wall can be checked and the likely stages explained.
Planning work in a period property
Homes in Dulwich, Herne Hill, Crystal Palace and Upper Norwood include period houses and conversions where original plaster can sit beside later boards and repairs.

Nova Coat & Plaster can discuss lime repairs alongside skimming and decorating where both are suitable. Fresh plaster must dry in its own time before paint is applied. The order and finish are agreed for the property rather than assumed from a standard recipe.
