Plastering & making good in Causeway Coast and Glens: how it works

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 Causeway Coast and Glens, the order of work matters as much as the steel: survey, calculations, approval, propping, installation, inspection and making good. We work in Coleraine, Limavady and Portrush and the surrounding villages. We run that sequence for you as one job with one point of contact.

Worth knowing before you start

  • 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.
  • 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.
  • 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.
  • 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.

Four stages, one team

  1. 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.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. Building control

    A full plans application or building notice goes to Causeway Coast and Glens Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.

  4. 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 rules for Causeway Coast and Glens

Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Causeway Coast and Glens Borough Council covers Causeway Coast and Glens. The engineer's calculations support the application, and a completion certificate is issued after the final inspection.

The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.

Questions about plastering & making good in Causeway Coast and Glens

Can I stay at home while the work is done in Causeway Coast and Glens?

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.

What happens at the survey visit in Causeway Coast and Glens?

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.

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.

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.

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.

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.

Who approves plastering & making good in Causeway Coast and Glens?

Structural work in Causeway Coast and Glens needs a full plans application or building notice to Causeway Coast and Glens Borough Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
