What should you ask a decorator about preparation?
Ask what is on the wall now, how it will be prepared, and which finish suits that surface. In older homes, those answers shape the specification more than colour does. The questions below are the ones that change quotes and outcomes, and they are worth asking before any work is booked.
Why the existing surface sets the specification
A room's existing surface decides what preparation is needed and which finish will sit well on it. Walls may be plaster, gypsum skim, or woodwork that has been recoated over time, and each surface behaves differently under a new coat. A decorator should be able to describe what is under the surface and what that means for preparation. If the answer stays general, the specification probably will too.
Preparation: what is actually included?
Preparation is the part of a decorating quote that is easiest to leave vague and hardest to see afterwards. Ask directly: is filling and sanding included, or is it an extra? Will stained or blown areas be treated before painting? For wallpaper removal, will the walls be washed, filled, and primed afterwards, or left bare for someone else? A decorator who separates preparation from decoration in the quote is giving you a clearer picture, not a more expensive one.
Finish choice: where limewash, wallpaper, and paint belong
Limewash suits breathable, mineral surfaces and rooms where a soft, chalky depth is wanted. It is less suited to walls sealed with modern acrylic paint, kitchens with heavy condensation, or high-traffic areas where a washable finish is more practical. Wallpaper works well where walls are sound and the pattern is doing the work; it needs a smooth, sealed surface underneath. For joinery, cabinetry, and sash windows, the choice is usually between hand-painting and spray painting, and that depends on whether the item can be removed, masked, or finished in place. None of these are universal answers — they follow the room.
What changes the specification in a period home
Sash windows are a good example. They are painted in place, they need to remain operable, and the paint line around the cords and beads matters. Hand-painted kitchens are another: doors and frames may be sprayed off-site or painted in place, and the preparation differs. Exterior painting depends on weather exposure and the condition of the substrate. Period-property decorating often involves repairing before decorating, and that repair work is part of the specification, not a surprise. If you are comparing quotes, compare what each one says about these details.
How to decide whether to hire a decorator
If the room is straightforward — sound walls, one finish, no repair work — the decision is mostly about time and finish quality. If the room has old joinery, wallpaper to remove, or a kitchen to refinish, the preparation and surface decisions are the ones that determine whether the result lasts. A calm next step is to ask for a written specification that names the surfaces, the preparation, and the finish for each area, then compare that against what you want from the room.
