What should you ask a decorator before booking?
Ask what the existing surface is, how it will be prepared, which finish suits it, and how the work will be sequenced around your household. Those four answers tell you more than any glossy brochure. A decorator who talks about substrate and preparation before colour is usually the one who will get the result you actually want.
Most homeowners start with colour. The better starting point is the wall itself. In period homes across Central London, West London, South West London, and Surrey, the surface often carries decades of decisions: old distemper, patches of filler, sealed plaster, or a previous coat that behaves differently from what is being applied now. A consultation that ignores this is a consultation that will produce surprises later.
Start with the room and the existing surface
A room tells you what the walls have been through. Kitchens and bathrooms hold moisture differently from a drawing room. Hallways take more contact. A Georgian or Victorian property may have lime plaster that needs to breathe, while a later extension may have a modern sealed surface. These are not small details — they change what can be specified.
When you speak to a decorator, describe the room honestly. Mention any damp patches, flaking, previous wallpaper, or areas that have been patched. Ask how they would read the surface before quoting. A decorator who wants to see the wall in person, rather than quote from a photograph, is doing the right thing.
This is also where you can ask about specific finishes. Limewash, for example, behaves differently depending on the wall behind it. It is not a universal coating, and a good decorator will say so rather than sell it into every room. The same applies to specialist finishes and spray painting — each has a place, and each has constraints.
Preparation is the part that decides the finish
Ask what preparation is included. Wallpaper removal and the preparation after it is a distinct stage, not a quick scrape. Old adhesive, torn paper, and damaged plaster all need attention before any paint or paper goes on. If preparation is vague in the quote, the finish will be vague in the result.
Woodwork matters too. Sash window painting, joinery painting, and hand-painted kitchens all depend on sanding, filling, and priming before the topcoat. Ask how many stages are involved and what happens between them. A calm, experienced decorator will talk you through this without turning it into a laboratory report.
If you are comparing quotes, compare the preparation, not just the colour. Two quotes can look similar on paper and differ entirely in what happens before the first coat.
Finish choice follows the surface, not the trend
Once the surface is understood, the finish becomes a practical decision. Interior painting and decorating, limewash finishes, wallpaper hanging, cabinetry and joinery refinishing, spray painting, exterior painting, period-property decorating, and sash window painting are all available — but not every finish suits every room.
Ask which finish the decorator would choose for your specific wall and why. Ask what happens if the surface turns out to be different once work begins. A good answer will describe a process, not a promise. For a period property, that process often includes a period-property decorating approach that respects the original materials.
Exterior work follows the same logic. Exterior painting depends on weather, substrate, and the condition of the existing coating. Ask how the decorator plans around the seasons and what preparation is needed before the exterior topcoat.
Sequencing, access, and household routine
Ask how the work will be sequenced. Which rooms first? How will drying times affect access? Will furniture need to move, and who moves it? These are practical questions that shape the experience of living through a decorating project.
If you are in a period home, ask about dust control and protection for original features. If you have a hand-painted kitchen, ask how the cabinets will be prepared and refitted. If you have sash windows, ask how they will be painted without disrupting their operation.
A decorator who answers these questions clearly is showing you how they work. That is more useful than any claim about being the best or the fastest.
When to bring in a decorator rather than do it yourself
Some jobs are manageable as a homeowner. Others are not. If the surface is uncertain, if the room has had multiple previous treatments, or if the finish is a specialist one, the risk of getting it wrong is higher than the cost of getting it right.
This is where a consultation earns its place. You are not just buying paint; you are buying a judgement about what the wall needs. For homeowners in Central London, West London, South West London, and Surrey, that judgement is often the difference between a finish that lasts and one that fails quietly.
If you are weighing up whether to hire someone, start with a conversation about the room and the surface. You can see how Pulse N' Paint describes its approach on the Painter & decorator in Barnes. page, and if you are further out, the Painter & decorator in Banstead. page covers that area. A short, specific conversation about your walls will tell you more than a long browse.
A calm next step
Write down what you know about the room: the surface, the previous finishes, the problem areas, and how you use the space. Then ask a decorator to talk through preparation and finish choice before you ask for a price. That order — surface first, finish second, price third — is the one that produces a specification you can trust.
