What plastering & making good involves in Coity

Our plastering & making good service in Coity covers everything from the first visit to the completion paperwork. The wider Bridgend area is covered as well. Postcode districts we cover here include CF31, CF32 and CF35.

Structural work leaves a trail behind it: a steel beam to hide, ragged wall ends, a strip of missing floor, cracked ceiling where props stood and holes where needles passed through. However good the steel, this is the part you look at every day, so it deserves the same care as the structure.

Key points for your project

  • Period cornicing and ceiling roses can often be repaired or run to match the existing profile. Where a wall is removed between two rooms with cornice, the ends are usually returned neatly along the new beam so the detail looks intentional.
  • Victorian and Edwardian ceilings are often lath and lime plaster, which can sag or come away when nearby work shakes it. Small areas can be patched to match, while larger damaged areas are usually overboarded or replaced for a sound result.
  • Fresh plaster has to dry before it is painted. A thin skim over board in a warm, ventilated room often dries within a few days to a week, while backing coats and deeper repairs take longer. Painting too soon can cause peeling and patchy colour.
  • Textured ceiling coatings applied before 2000 can contain asbestos. Before a textured ceiling is cut, scraped or sanded, a sample is tested or an asbestos survey of the area is arranged, and the finish is only disturbed once the result is known.
  • The cost depends mainly on the area to repair, the condition of the ceilings, whether period details need matching, and the size of the floor infill. Overboarding a badly damaged ceiling can work out more economical than patching it piece by piece.

Plastering & making good in Coity: your questions

How much does plastering & making good cost in Coity?

As a guide, budget £270–£1,090 including VAT for plastering and making good in Coity, based on published UK cost guides adjusted for prices in Wales (-9%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

What happens at the survey visit in Coity?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

Can you repair a lath and plaster ceiling?

Yes. Small areas can be patched with lath and lime-based plaster, or with board cut in and skimmed to match. Where large areas have sagged or pulled away from the laths, overboarding or replacing the ceiling is often the sounder repair. We assess the condition at the survey and price the right approach.

How long after a knock-through can I decorate?

Once the new plaster has dried right through, which for a thin skim in a warm, ventilated room is often a few days to a week. Deeper repairs and backing coats take longer. Plaster turns from dark to an even pale colour when it is dry, and painting before then risks poor adhesion.

How do you hide a steel beam in the ceiling?

Most beams are boxed with fire-rated plasterboard fixed to a light frame, then finished with corner beads and a skim coat so they read as part of the ceiling. If you want no downstand at all, the beam has to be set into the floor void when it is installed, which is decided at the design stage.

Do I need a party wall agreement for plastering & making good in Coity?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
