What to ask before period-property decorating begins
Before you commission decorating work in a period home, ask the decorator three things: how they will treat the existing surfaces, what preparation the original plaster and joinery need, and how the finish will behave over time. In a Victorian, Edwardian, or Georgian house, the substrate usually dictates the specification. A decorator who talks through the walls and woodwork before the colour is a better sign than one who starts with a shade card.
This article is a consultation checklist for owners of older homes in west, south-west, and central London, and in Surrey. It complements service-specific guides on sash window painting, limewash, and sprayed finishes by focusing on the whole-room conversation: what to ask when the house itself, rather than one element of it, is the subject of the work.
Start with the room and the existing surface
Open the consultation in the room itself, not over a brochure. Ask the decorator what they see on the walls: original lime plaster, later gypsum patches, lining paper, or modern emulsion built up over decades. Each behaves differently under new paint, and the honest answer is rarely that everything can simply be coated.
Ask specifically what will happen to uneven or aged plaster. In period homes, hairline movement and old repairs are normal, and the question is whether the decorator plans to stabilise, fill, or line the wall. If wallpaper is present, ask how it will be removed and what preparation follows removal, because the state of the wall underneath often changes once the paper is off. A decorator who describes that sequence plainly is telling you something useful about how they work.
Ask how the specification could change
The most valuable consultation question is also the simplest: what would change your recommendation? A good decorator will answer in terms of the surface. Old plaster that cannot take a modern acrylic system may point towards a breathable finish. Woodwork with decades of accumulated paint may need stripping back or careful sanding rather than another coat on top. Original joinery that has been sealed with modern products may limit which finishes are viable at all.
Ask what happens if the wall turns out to be in worse condition than it looks. Preparation is the substance of period-property decorating, and a decorator should be able to describe, in plain terms, what they will do when the room reveals something unexpected behind the paper or under the existing paint.
Ask about the finishes on offer
Period homes suit a range of finishes, and the consultation is the moment to hear the options rather than be handed one. Ask about interior painting and decorating approaches for walls and ceilings, joinery painting for skirtings, architraves, and doors, and specialist finishes where the room calls for something beyond standard emulsion. If you are considering limewash, ask directly about its limits: high-traffic areas, kitchens with heavy condensation, and walls previously sealed with modern acrylic paint are all situations where limewash may not be the right specification, and a decorator should say so unprompted.
For woodwork, ask how the decorator handles hand-painted kitchens or detailed joinery if those form part of your project, and how they protect surrounding original features while working. The answers tell you whether the decorator thinks in terms of the whole house or just the wall in front of them.
Ask about the working method
Practical questions matter as much as technical ones. Ask how the room will be protected, how dust from preparation will be managed, and what order the work will follow. Ask who will be on site and how the decorator communicates as the job progresses. In an occupied period home, the disruption of preparation is usually longer than the painting itself, so the conversation should reflect that.
If your project includes sash windows or exterior work, ask whether the same team handles those or whether the specification changes for external exposure. Period-property decorating often touches several surfaces in one room, and you want to know the plan for each before work starts.
A calm next step
When you have shortlisted a decorator, walk them through the room and ask them to describe the preparation they would carry out, surface by surface, before quoting. That single conversation will tell you more than any brochure.
