Planning plastering & making good in Carshalton
For homes in Carshalton and the CR4, SM1, SM2, SM3 and SM4 districts, we handle plastering & making good from survey to sign-off. We also cover the surrounding towns and villages in London. The beam is sized by a structural engineer and inspected before it is boxed in.
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
- 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.
- 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.
- Hairline cracks sometimes appear along board joints or where new plaster meets old, as the building settles onto the steel and the plaster dries out. They are normal in the first months and are usually filled at the next redecoration.
- 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.
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 Carshalton
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.
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
Can you work on older or listed homes in Carshalton?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
How much does plastering & making good cost in Carshalton?
As a guide, budget £380–£1,540 including VAT for plastering and making good in Carshalton, 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.
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.
Do you decorate after making good?
Not usually. Making good leaves surfaces skimmed, dry and ready for paint, with trims refitted, and decoration is normally left to you or your decorator so you can choose colours and finishes yourself. Whoever paints should start with a thinned mist coat on the new plaster before the main coats.
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.
How soon can plastering & making good start in Carshalton?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
