Planning plastering & making good in Westminster
If you live in Westminster, plastering & making good can usually be planned and priced after a single survey visit. Our coverage runs across London, so nearby villages are included too. We cover SW1, W1 and WC2, and we fix the price in writing once the layout and scope are agreed.
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
- 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.
- 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.
- 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.
- 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.
- 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.
What happens, step by step
Free visit
A short visit to Westminster to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
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 Westminster
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.
Local questions answered
Do you also work near Westminster?
Yes. We also cover nearby towns including Pimlico, Chelsea, Battersea and Brixton.
Can I stay at home while the work is done in Westminster?
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.
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.
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.
