Planning plastering & making good in Birmingham

For homes in Birmingham and the B1, B2, B3, B4 and B5 districts, we handle plastering & making good from survey to sign-off. The wider the West Midlands area is covered as well. The beam is sized by a structural engineer and inspected before it is boxed in.

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

  • 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.
  • 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.
  • 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.

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 Birmingham City Council, 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.

Building control and neighbours in Birmingham

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 Birmingham City Council 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 Birmingham?

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.

What happens at the survey visit in Birmingham?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

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.

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.

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

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.
