Plastering & making good in Harrow: how it works
Plastering & making good in Harrow 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.
Key points for your project
- 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.
- 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.
- 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.
- When a wall is removed, a strip of floor goes with it. On suspended timber floors the gap is joisted and boarded, and on solid floors it is filled and screeded. Either way, the infill must sit level so new flooring does not show a ridge.
- 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.
Four stages, one team
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.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
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.
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 control and neighbours in Harrow
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.
Local questions answered
Do I need a party wall agreement for plastering & making good in Harrow?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
Who approves plastering & making good in Harrow?
Structural work in Harrow needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
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.
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.
How do you hide a steel beam in the ceiling?
Most beams are boxed with fire-rated plasterboard fixed to a light frame, then finished with corner beads and a skim coat so they read as part of the ceiling. If you want no downstand at all, the beam has to be set into the floor void when it is installed, which is decided at the design stage.
How much does plastering & making good cost in Harrow?
As a guide, budget £380–£1,540 including VAT for plastering and making good in Harrow, 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.
