Plastering & making good in Belfast: 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.

Plastering & making good in Belfast follows the same careful process wherever the property is: a survey, an engineer's design, the right approval and safe temporary works. Coverage takes in Castlereagh and everywhere in between. We price it all up front so there are no surprises once the wall is open.

Worth knowing before you start

  • 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.
  • Period cornicing and ceiling roses can often be repaired or run to match the existing profile. Where a wall is removed between two rooms with cornice, the ends are usually returned neatly along the new beam so the detail looks intentional.
  • 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 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.
  • 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.

From survey to sign-off in Belfast

  1. Free visit

    A short visit to Belfast to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    A full plans application or building notice goes to Belfast City Council under the Building Regulations (Northern Ireland) 2012 before work begins.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in Belfast

In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Belfast that is Belfast City Council. We submit a full plans application or building notice before work starts and book the inspections.

Northern Ireland has no Party Wall Act, so there is no statutory notice to serve. Where the steel bears into a shared wall, the title deeds and the general law apply, and agreeing the work with your neighbour in writing first is good practice.

Questions about plastering & making good in Belfast

Do you cover Belfast for plastering & making good?

Yes. We carry out plastering & making good in Belfast. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Do I need a party wall agreement for plastering & making good in Belfast?

There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.

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.

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.

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.

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.
