A damaged ceiling sit somewhere between cosmetic and structural, and the right response varies from a simple filler-and-paint job to a complete overboard-and-skim. Knowing the difference matters because doing the minor job when the wall actually needs the major one leaves you doing the same work again in two years, and doing the major job when the minor one would have sufficed spends money unnecessarily.

Minor ceiling cracks are almost universal in older Bournemouth houses and rarely a cause for concern. Buildings move constantly – thermal expansion, seasonal humidity changes, minor settlement – and rigid finishes like plaster ceilings show that movement as hairline cracks along joists or at wall junctions. These cracks are cosmetic. Filling them with a flexible filler, taping the joint with paper tape and skimming lightly over, then repainting, is the standard fix. The crack may reappear over years but is not doing structural harm.

A sagging ceiling or hanging down from its correct level is a different matter and needs proper investigation. The most common cause in older properties is failure of the mechanical key between old lath-and-plaster and the ceiling joists above – the plaster has separated from the laths and is being held up by gravity and paint. Once the sag is visible, gravity is going to win eventually, and the ceiling will come down in sheets. This is not a fix-and-forget situation. Either the ceiling is stripped and replaced, or – more commonly now – it is overboarded with new plasterboard fixed up through the old plaster into the joists behind, and skimmed.

Water damage to a ceiling requires understanding where the water came from before any repair is attempted. A stain from an old, since-resolved leak – a fixed roof, a stopped pipe drip – can be sealed with a stain-blocking primer and painted over. A stain from an active leak needs the leak fixing first, then the ceiling to dry completely, and only then can any surface repair sensibly happen. Painting over active damp on a ceiling never works; the paint peels within weeks and the same stain reappears. Any ceiling repair job should start with a check that no active water source is still affecting the area.

Textured ceilings were common from the 1960s through to the 1990s and are now recognised as a maintenance headache. Some versions installed before around 1985 contain asbestos, and even minor sanding or scraping of unknown artex is potentially hazardous. The modern approach is not to remove artex – which risks the material becoming airborne – but to overboard it with fresh plasterboard, fixed through into the joists, and skim the new surface flat. This encapsulates the old material behind a new, sound ceiling and gives a modern smooth finish.

Full ceiling replacement, stripping the old and starting again with new joists or plasterboard, is only necessary in specific cases. Extensive water damage that has rotted the structure above, artex removal in listed properties where overboarding is not appropriate, or major structural changes to the building all justify full replacement. In most other cases, overboarding is faster, cleaner, cheaper and preserves the structure above.

Coving and cornices are one of the character features that older Bournemouth houses often still have, and they are worth preserving in any ceiling job. When overboarding, the new plasterboard is packed out to sit flush with the top of the coving so the transition works visually. When re-plastering fully, the coving is protected during the work and any damage is made good with fibrous plaster patches from a specialist supplier. Ripping out original coving to make ceiling work easier is a shame in any period property and is almost always avoidable with a bit of patience.

Kitchen and bathroom ceilings deserve particular attention because of moisture. A bathroom ceiling with poor extraction spends hours a day at high humidity, and the finish on such a ceiling needs to be moisture-resistant. Bathroom-grade paint over a well-sealed plaster surface is the minimum standard; better still, moisture-resistant plasterboard combined with proper mechanical extraction. Ceilings and coving that show mould spots on the surface are ceilings where extraction is inadequate, and no amount of surface repair fixes the underlying problem.

The finished quality of a repaired ceiling is largely down to the plasterer. A properly-finished ceiling repair, whether a patch or a full skim, is invisible after decoration – no visible joins, no differences in surface texture between old and new work. Anything less than that is a plasterer worth watching more carefully on the rest of the job. Any plastering contractor covering ceiling work should be happy to show recent ceiling work before being hired.
