About our plastering & making good service in Blackwood
We carry out plastering & making good in Blackwood, covering the CF81, CF82 and NP12 postcode districts. Our coverage runs across Caerphilly, so nearby villages are included too. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We make good as the final stage of our structural jobs, and can quote it separately where another firm has fitted the steel. It covers boxing and fire boarding, plastering and skimming, floor infills and skirting, leaving smooth, dry surfaces for your decorator.
What to expect
- Plastering itself is wet rather than dusty, but cutting back old plaster and sanding filler is not. Work areas are sheeted off, floors protected and dust extraction used when cutting, so the mess stays in the room being worked on.
- Metal angle beads on every outside corner of the boxing give crisp, straight lines and protect the edges from knocks. They are set true to the ceiling and walls, so a slightly out-of-level beam does not show once skimmed.
- New plaster is very absorbent, so the first coat of emulsion is normally thinned with water as a mist coat to seal it. Skipping this step is a frequent reason paint flakes off fresh plaster within weeks of decorating.
- 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.
- 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.
How the job runs in Blackwood
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit the application or notice to Caerphilly County Borough Council under the Building Regulations as they apply in Wales, before work starts.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Blackwood
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Caerphilly County Borough Council handles building control for Blackwood. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.
Plastering & making good in Blackwood: your questions
Can I stay at home while the work is done in Blackwood?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
How soon can plastering & making good start in Blackwood?
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.
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.
