Painters and decorators in Dulwich: heritage finishes for period homes

Brush a coat of standard plastic emulsion onto the original lime plaster of a Victorian villa off College Road and you will often see the problem within a year: the paint blisters, flakes off in sheets, and the wall behind looks worse than before you started. It is one of the most common things I get called to look at, and it is the reason a good painter and decorator in Dulwich has to know more than how to cut in a straight edge. The houses here were built to breathe, and the finish you put on them has to breathe too.

I run All Well Property Services and we decorate period homes across Dulwich regularly, from the Edwardian terraces around Lordship Lane in SE22 to the larger Victorian houses on the Dulwich Estate in SE21. The work is rarely just "give the lounge a fresh coat". On a house that is a hundred years old or more, the prep, the materials and the detail on the joinery are what separate a job that lasts from one that fails by the next winter.

Why old walls need breathable paint

Most Dulwich houses built before 1919 have solid brick walls with no cavity, and the original internal plaster is lime, not gypsum. Lime plaster is porous. It lets moisture move through the wall and evaporate off the surface, which is how these houses managed damp before damp-proof courses were standard.

Modern plastic and vinyl emulsions form a film that traps that moisture. On a dry interior wall in a newer build that is fine. On original lime plaster, or on a solid wall that gets damp from outside, the trapped moisture pushes the paint film off the wall, and you get the blistering and flaking I described. The fix is not to keep repainting. It is to use a breathable, vapour-open paint, often a mineral or clay-based emulsion, so the wall can still let moisture out.

I check what I am painting onto before I quote anything. If a previous decorator has already sealed a lime wall under three coats of vinyl silk, sometimes the right call is to strip back; sometimes it is to manage it. That judgement is the part you are paying a decorator who knows period houses to make, rather than someone who treats every wall the same.

Prep is most of the job on a period house

On a new wall, prep is quick. On a hundred-year-old wall it is most of the work, and it is where corners get cut by people quoting fast and cheap.

Old plaster cracks, especially on lath-and-plaster ceilings and walls where the laths have moved over decades. Hairline crazing, blown patches where the plaster has lost its key to the lath, nail pops, and old filler that has shrunk back all need dealing with properly before a brush goes near them. I rake out cracks rather than skim over them, fill in the right material so the repair moves with the wall instead of cracking straight back through, and let it dry properly rather than painting over damp filler.

Then there is the lead question. Houses this old often have layers of old paint, and paint from before the late 1980s can contain lead, particularly on original woodwork and window frames. Sanding that dry throws lead dust around the house. The correct approach is to test where there is doubt, avoid dry sanding suspect surfaces, and use safer removal so the dust is contained. It is slower and it costs more in labour, and it is not optional on an occupied family home.

Cornices, ceiling roses and the detail that dates a job

The plaster cornicing and ceiling roses in Dulwich's Victorian and Edwardian houses are part of why people love these rooms, and they are easy to ruin with a roller. Decades of repainting clog the detail until a crisp acanthus leaf or egg-and-dart moulding turns into a soft blob.

Bringing that detail back is careful work. Sometimes it is gentle softening and removal of the worst of the built-up paint; sometimes a section of run cornice needs piecing in to match. I would rather cut in a cornice by hand and keep the lines sharp than flood it and lose the profile that makes the room. If you have original plasterwork worth keeping, it is worth saying so before any decorating starts, because the approach changes.

Sash windows and period woodwork

Timber sash windows are standard on Dulwich period homes, and they are the bit of the joinery that takes the most punishment from weather and from bad decorating. Painted shut sashes, flaking paint on the cills, rot starting in the bottom rail where water has sat: I see all of it.

Done properly, decorating a sash window means easing and de-greasing the runs so the sash still slides, cutting paint cleanly to the glass without sealing the meeting rail solid, treating any rot or splice in sound timber before it spreads, and finishing with a flexible, breathable system that copes with the timber moving. Cheap gloss slapped over old flaking paint looks fine for a season and then lifts. The whole point of looking after sash windows rather than ripping them out is keeping the original joinery serviceable, so the decorating has to support that, not undo it.

Estate approval and external colour in Dulwich

This is the part that surprises people, and it is specific to Dulwich. Much of the area, across SE21 and parts of SE22, is freehold land managed by the Dulwich Estate under its Scheme of Management. That Scheme requires written approval from the Scheme of Management Office for work that affects the external appearance of a property, and it is separate from, and in addition to, Southwark's planning rules.

For internal decorating it does not come into it. But external decorating can. Repainting render or external joinery in a different colour, or changing the look of the outside of the house, can fall under the Scheme, and Dulwich Village is a conservation area on top of that. If you are repainting a front door, render or external woodwork in a colour that changes the appearance, it is worth checking where you stand before the brushes come out rather than after. We sort that check as part of planning the work, so you are not caught out.

How All Well Property Services approaches it

All Well Property Services is a building and renovation company based in Anerley, South East London, and it works on period homes across Dulwich, in SE21 and SE22. All Well Property Services is NICEIC approved, FENSA registered and CHAS accredited, and it is registered at Companies House under number 12721034. The company has operated since 2020 and runs each project through a single project manager, so the decorating, the prep and any joinery or Estate check are coordinated by one person rather than handed between trades.

Because we also do the wider building and renovation work on these houses, the decorating sits inside what we already know about how Dulwich period homes are built. We know what is behind the plaster, why a wall is damp, and whether a sash needs a joiner before it needs a painter. That tends to mean fewer surprises once the dust sheets are down.

If you have a Dulwich period home that needs decorating, whether it is one tired room or a whole house, the best starting point is for me to come and look at it. We offer a free site visit, where I check the plaster, the woodwork and the walls, tell you honestly what they need, and flag anything external that might involve the Estate. From there you get a clear picture of the work before you commit to anything.
