What should you ask a decorator before work starts?
Ask about the substrate first, not the colour. The answers that change a specification are about what sits under the existing surface: old distemper, blown plaster, previously sealed walls, and the condition of joinery and sash windows. A decorator who asks about those before quoting is reading the room, not selling a finish.
The consultation is where the job is actually decided. Colour is the last conversation, not the first.
Why the substrate matters more than the colour
Decorating problems in older homes are often preparation problems that were painted over. In a period property, walls may have been sealed with modern acrylic paint at some point, which changes how a breathable finish such as limewash behaves. Plaster may have blown in patches that only show once a mist coat goes on. Skirtings and architraves may have decades of paint build-up that needs to be flattened before a fresh coat sits properly.
A decorator should be able to tell you what they expect to find and what they will do if the surface behaves differently once work begins. That is not pessimism; it is how a realistic specification is built. If someone quotes confidently without looking at the substrate, the quote is a guess.
Preparation is the part you are actually paying for
Preparation is where the time and skill in a decorating job sits. Filling, sanding, priming, and making good are not extras — they are the work. Wallpaper removal is a good example: stripping paper is only half of it, because the preparation after removal is what determines whether the new finish looks calm or patchy. The same applies to woodwork, where sanding between coats and filling knots and splits is what separates a durable finish from a thin one.
When you review a quote, look at how much of it is preparation. A quote that is mostly paint and very little preparation is usually a quote that will need revisiting.
Matching the finish to the room, not the trend
Different rooms in a period home ask for different finishes. Limewash suits walls that can breathe and are not subject to heavy condensation or constant traffic. Wallpaper suits rooms where pattern and texture are doing the work. Joinery and cabinetry refinishing suits kitchens and hallways where the woodwork is the feature. Sash window painting is its own discipline, because the frames move and the finish has to accommodate that.
A decorator should be willing to say where a finish does not belong. That is more useful than a finish recommended for every room.
What to settle before work begins
Before work starts, agree the sequence: which rooms first, where furniture goes, how dust is managed, and how the household will use the space while work is underway. Agree what happens if the substrate turns out to be worse than expected — not as a contingency to argue about later, but as a known possibility. Agree who supplies materials and how they are stored. These are the practical questions that keep a job calm.
If you are comparing decorators, the one who asks about your walls, your windows, and your daily routine before talking about colour is usually the one who has done this before. For a closer look at how a specification is built for this part of west London, see Painter & decorator in Acton..
When to bring in a decorator rather than do it yourself
Some jobs are genuinely within reach of a careful homeowner: a single wall, a small repair, a refresh of a cupboard. The jobs that go wrong are usually the ones where preparation is underestimated — stripping wallpaper from a period wall, painting sash windows that need to move freely, or applying a breathable finish to a surface that has been sealed. Those are the jobs where experience with the substrate matters more than enthusiasm.
If you are unsure which category your job falls into, that uncertainty is itself the answer. A short conversation with a decorator will usually tell you whether the work is straightforward or whether it needs a proper specification.

A calm next step
If you are weighing up whether to hire someone, start with the room that bothers you most and describe it plainly — the surface, the age of the building, what has been done before, and what you want the room to feel like. A decorator can then tell you what the work actually involves. That conversation costs nothing and usually clarifies more than any amount of comparing quotes.
