Plastering & making good in Gelligaer: how it works
Planning plastering & making good in Gelligaer? Our team covers CF81, CF82 and NP12 and the streets around them. The wider Caerphilly area is covered as well. You get one written quote for the calculations, approvals, propping, steel and making good.
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
- Making good is the last chance to route cables neatly before surfaces close up. Sockets, switches and lights moved for the new layout are first-fixed before boarding, and pipes crossing the old wall line can run within the floor infill.
- 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.
- 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.
- 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.
- 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.

Building control and neighbours in Gelligaer
Welsh building regulations treat beams and new openings as controlled building work. We apply to Caerphilly County Borough 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.
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 Gelligaer: your questions
What happens at the survey visit in Gelligaer?
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 I stay at home while the work is done in Gelligaer?
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.
Will cracks appear after plastering?
Small hairline cracks can appear in the first months as the plaster dries and the building settles onto the new steel. They are cosmetic and normal, and are usually filled when you next repaint. Wide or growing cracks are different and should be reported, as they can point to movement that needs checking.
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.
What happens to the floor where the wall was removed?
The gap left by the wall is filled to match the floor on either side. Suspended timber floors get new joists and boards, solid floors are filled and screeded, and the infill is levelled so carpet, laminate or tiles can run straight across the room without a visible ridge.
Who approves plastering & making good in Gelligaer?
Structural work in Gelligaer needs a building control application to Caerphilly County Borough Council under the Welsh regulations, with a commencement notice before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
