What plastering & making good involves in Carmarthenshire
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.
From the first survey visit to the completion certificate, we take care of plastering & making good across Carmarthenshire. Towns we cover include Carmarthen, Ammanford and Burry Port, among other places in the area. The engineer sizes the steel, we deal with Carmarthenshire County Council, and our team fits and packs the beam before making good.
Worth knowing before you start
- 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.
- 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.
- 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.
- Fire-rated plasterboard is used for boxing steel that needs fire protection, while standard or moisture-resistant board suits ordinary ceiling and wall repairs. Using the right board in each place avoids rework when building control inspects.
- When a wall is removed, a strip of floor goes with it. On suspended timber floors the gap is joisted and boarded, and on solid floors it is filled and screeded. Either way, the infill must sit level so new flooring does not show a ridge.
What happens, step by step
Survey in Carmarthenshire
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
We submit the application or notice to Carmarthenshire County Council under the Building Regulations as they apply in Wales, before work starts.
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.

Approvals in Carmarthenshire
Welsh building regulations treat beams and new openings as controlled building work. We apply to Carmarthenshire County Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Questions about plastering & making good in Carmarthenshire
How soon can plastering & making good start in Carmarthenshire?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
How much does plastering & making good cost in Carmarthenshire?
As a guide, budget £270–£1,090 including VAT for plastering and making good in Carmarthenshire, 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.
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 you decorate after making good?
Not usually. Making good leaves surfaces skimmed, dry and ready for paint, with trims refitted, and decoration is normally left to you or your decorator so you can choose colours and finishes yourself. Whoever paints should start with a thinned mist coat on the new plaster before the main coats.
Is plastering included when a load-bearing wall is removed?
Yes, on our structural jobs making good is priced as part of the work and itemised on the written quote, so you can see exactly what is included. If another firm is doing the steelwork, check their quote closely, as some stop at the beam and leave plastering, floor infill and skirting for you to arrange.
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.
Which towns in Carmarthenshire do you cover?
We cover towns including Llanelli, Ammanford, Carmarthen and Burry Port, plus the villages and smaller towns around them.
