What are cornices and wall mouldings?

A cornice is the decorative moulding that runs along the join between wall and ceiling; decorative wall mouldings add panels, frames and borders to the wall itself and give a room its character. They are made from plaster, polyurethane or wood-effect polymer, and bring elegance to both classic and contemporary interiors.

Types of cornice

  • Classic cornice: traditional motifs and ornament.
  • Modern cornice: plain, minimal lines.
  • LED cornice: a concealed light channel for a soft, atmospheric glow.

Wall mouldings

  • Wall panelling (wainscoting): vertical and horizontal mouldings that create a panelled or framed effect.
  • Border mouldings: decorative lines behind the bed, as a feature in the living room or along the entrance hall.
  • Wood-effect mouldings: polymer mouldings in lacquer, walnut and oak tones for natural warmth.
  • LED mouldings: back-lit moulding panels for a modern look.

FAQ

Frequently Asked Questions About Cornices & Wall Mouldings

We have compiled the topics our clients are most curious about

How long does a cornice take to fit?

One to two days for a room, three to five days for a whole flat.

Plaster or foam?

Plaster lasts longer, foam costs less. Plaster is the usual choice.

How does an LED cornice work?

A concealed channel is formed inside the cornice and an LED strip is fitted into it.

Does it need painting afterwards?

Yes — we fill the joints and paint it ourselves.

Can cornices be fitted in an older building?

Yes, as long as the existing plaster and ceiling are sound. We spot weak surfaces during the survey and consolidate them first.

Plaster cornice or polystyrene coving — which should I choose?

They look alike and behave differently. Plaster cornice is gypsum-based: heavy, rigid, its joints fill to a seamless run, and it is non-combustible. Polystyrene (EPS) coving is foam: light, cheap, glued up — but combustible, easily dented, prone to yellowing, and its joints stay visible through paint. Polyurethane sits between the two: durable and moisture-tolerant, at a higher price. For a home where the finish will be looked at, we recommend plaster; we use polystyrene only where budget is genuinely fixed and fire is not a concern.

How deep should the cornice be for my ceiling height?

It is a question of proportion. At 2.40–2.60 m a 5–8 cm profile sits right; anything heavier presses the room down and makes the ceiling look lower. Between 2.70 and 3.00 m, 8–12 cm carries comfortably. Above 3 m and in period-height rooms, 15 cm and beyond stays in proportion. If concealed lighting is going in as well, add 3–4 cm to the width, otherwise the light channel overwhelms the moulding.

How much space does concealed cove lighting need?

For the LED strip's light to spread, the channel wants at least 8 cm of depth, ideally 10–12 cm. If the strip sits too close to the wall you get a hard line and scalloping; leaving 6–8 cm of standoff prevents it. We finish the inside of the channel matt white — a glossy surface reflects the light in points, a matt one spreads it evenly.

Why does cornice crack, and how is it prevented?

Cracks almost always start at joints; the material itself does not crack. Three causes: mitres forced instead of cut on site, adhesive that is insufficient or the wrong type, and normal building settlement or thermal movement concentrating on a rigid line. After filling we bridge the joints with tape and leave a movement allowance on long straight runs. A new building moves most in its first year, so where possible applying a few months after handover reduces the risk.

Can plaster cornice be used in a bathroom or kitchen?

Kitchens are fine. In a bathroom, plaster cornice in the zone directly exposed to shower steam will draw moisture over time and the surface deteriorates. There we specify polyurethane profile instead — it tolerates water and vapour and takes paint. Away from the shower, and in well-ventilated rooms, plaster is perfectly serviceable.

Should the cornice and ceiling rose be done together?

Not compulsory, but they must be planned together. The rose centres on the light outlet; the cornice line follows the room's actual geometry. If the room is not truly square — most are not — a mismatch between those two axes is immediately visible. We set both out at the same time with the same crew; a rose added later usually ends up visibly off-centre.

Can you carry out the work while I am abroad?

Yes. We agree the scope in writing before starting, send dated progress photographs at each stage, and can hold a video call on site whenever you want to see something specific. Keys are handed over against a written record, and the flat is cleaned and photographed again at handover.

How is the scope agreed and what does the written quote contain?

After the survey you receive a written scope listing the rooms and areas covered, the system chosen for each, the brand and product of the boards, profiles and insulation, the surface finish level, and the number of working days. Anything not on that list is not in the price, which is what stops the mid-project additions that make contractor quotes unreliable. Nothing is charged beyond the written scope without your approval.

How long before the property is usable or ready to let?

Ceilings and partitions leave the space usable as soon as the crew finishes. Painting needs longer: the film cures over roughly a week, and the smell in a ventilated flat clears within two to three days. If a flat is being prepared for tenants, plan on a few extra days after handover for airing and cleaning rather than scheduling a viewing for the day of completion.
