What plastering & making good involves in Derry City and Strabane
Plastering and making good is the finishing work after a beam goes in or a wall comes out: boxing the steel, fixing corner beads, patching ceilings and wall ends, infilling the floor where the wall stood and skimming everything smooth. The aim is a room that looks as if the opening was always there, ready for paint.
If you are planning plastering & making good in Derry City and Strabane, the order of work matters as much as the steel: survey, calculations, approval, propping, installation, inspection and making good. Coverage takes in Derry/Londonderry and Strabane and everywhere in between. We run that sequence for you as one job with one point of contact.
What to expect
- 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.
- Making good is easy to underestimate when budgeting. Removing a wall disturbs the ceiling, both wall ends and the floor, and props and needles leave their own marks, so the finishing work usually covers far more than the opening itself.
- 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.
- A boxed beam usually leaves a downstand below the ceiling line. Where a flat ceiling is wanted, the beam has to be set up into the floor void during installation, so the finish needs deciding before the steel goes in, not after.
- Hairline cracks sometimes appear along board joints or where new plaster meets old, as the building settles onto the steel and the plaster dries out. They are normal in the first months and are usually filled at the next redecoration.
What happens, step by step
Survey in Derry City and Strabane
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
A full plans application or building notice goes to Derry City and Strabane District Council under the Building Regulations (Northern Ireland) 2012 before work begins.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Plastering & making good in Derry City and Strabane: your questions
How much does plastering & making good cost in Derry City and Strabane?
As a guide, budget £260–£1,030 including VAT for plastering and making good in Derry City and Strabane, based on published UK cost guides adjusted for prices in Northern Ireland (-14%). 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.
How soon can plastering & making good start in Derry City and Strabane?
Start dates depend on the engineer's calculations, the building control approval and any agreement needed with neighbours. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
Do I need building control approval for plastering?
Not for plastering on its own. However, where it covers new structural steel, building control usually needs to inspect the beam and its fire protection before it is boxed in and skimmed. That is why, on structural jobs, the making good is timed around the building control visit.
Can you match my old textured ceiling?
Often, yes, although a perfect match is hard over large patches. Before anything is touched, a textured coating applied before 2000 is tested for asbestos. Small areas can then be re-textured to blend in, while many people choose to skim the whole ceiling flat for a cleaner, consistent finish.
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.
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.
