What should you ask a decorator before work begins?
Ask about the surface first, not the colour. In period homes, the answers that matter most concern what is already on the wall, how it was applied, and what preparation it needs. A decorator who starts with substrate questions is reading the room before quoting. That is the conversation worth having before you commit.
Start with the room and the existing surface
Every specification begins with what is already there. In Victorian, Edwardian, and Georgian houses, walls and woodwork have often been repainted many times, and each layer changes how the next one behaves. Skimmed plaster, old distemper, and filled cracks all behave differently under new coatings.
This is why a useful consultation does not begin with a colour chart. It begins with questions about the room: which walls face the weather, how the room is used, and what the existing paint actually is. Those answers determine what preparation is required and how the work should be sequenced.
For a homeowner, the practical point is simple. If a decorator cannot tell you what is on your walls and why it matters, the specification is guesswork.
Preparation is the specification
Preparation is not a preliminary to the job. It is the job. In older properties, wall and woodwork preparation often decides the final result more than the paint itself. Filling, sanding, priming, and making good are where a finish either holds or fails.
Ask how the decorator will prepare each surface. Ask what happens after wallpaper removal, because the plaster underneath is rarely ready to paint straight away. Ask how joinery will be prepared before painting, and whether sash windows will be taken back to bare wood or painted over existing coatings. These are not technical traps. They are the questions that separate a considered specification from a quick quote.
Understanding that before work starts makes the process calmer for everyone.
Finish choice follows the surface, not the trend
Limewash, wallpaper, specialist finishes, and hand-painted kitchens all have their place, but the place is determined by the surface and the room. A decorator should be able to explain why a finish is suitable for your room, and equally why it is not. That explanation is more useful than any showroom sample.
Wallpaper hanging and wallpaper removal are similarly surface-led. Hanging paper over a poorly prepared wall will show every imperfection. Removing paper reveals what the wall has been hiding, and the preparation after removal is often the real work.
For cabinetry and joinery refinishing, the question is whether the existing coating will accept a new finish and whether spray painting or hand painting is appropriate for the space. Sash window painting follows the same logic: the condition of the timber and the existing paint system determine the approach.
What changes the specification in London and Surrey homes
Older properties in London and Surrey vary widely, and the details of your own home are what matter. Solid brick walls, original timber sash windows, and a history of repairs and repainting all affect what preparation is needed and which finishes will perform well. Some homes have been extended or altered, introducing modern materials alongside old ones.
Exterior painting also depends on exposure and substrate. A rendered wall, a painted brick facade, and a timber sash window all weather differently, and the specification should reflect that.
When you speak to a decorator, ask how they assess these factors. A useful answer will refer to the specific surfaces in your home, not a general description of services. If you are comparing options, Painter & decorator in Acton. is a reasonable place to see how one decorator frames that conversation.
How to decide whether to hire a decorator
If your home is a period property and the work involves preparation, substrate assessment, or finish selection, the decision is less about cost per room and more about whether the specification is sound. A decorator who asks about the surface, explains the preparation, and is honest about where a finish will not work is giving you the information you need to decide.
For homeowners across Central London, West London, South West London, and Surrey, the next step is a conversation about your rooms, not a price list. Areas we cover across London and Surrey. if you want to see whether your area is covered before you start that conversation.
One calm next step: invite a decorator to look at the rooms you have in mind, and ask what they would need to know about the surfaces before specifying anything. The answers will tell you more than any quote.
