Planning plastering & making good in Chelsea

Plastering & making good in Chelsea is planned around the house, not a standard kit. Our coverage runs across London, so nearby villages are included too. We visit, measure and check what the wall carries, then arrange calculations and building control approval before any steel is ordered.

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.

What to expect

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

What happens, step by step

  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

    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.

  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.

Approvals in Chelsea

For Chelsea, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

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.

Plastering & making good near Chelsea

Plastering & making good in Chelsea: your questions

Can I stay at home while the work is done in Chelsea?

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.

Do you also work near Chelsea?

Yes. We also cover nearby towns including Battersea, Fulham, Pimlico and Westminster.

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.

Do you replace skirting boards and door frames after a knock-through?

Yes, where the work affects them. Skirting is extended or replaced so it runs through the new opening, and door linings and architraves are refitted or replaced where an opening has changed. Where period mouldings are involved, matching profiles can usually be sourced or made up to suit.

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.

How much does plastering & making good cost in Chelsea?

As a guide, budget £380–£1,540 including VAT for plastering and making good in Chelsea, based on published UK cost guides adjusted for London prices (+28%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
