What plastering & making good involves in Chesham

We cover plastering & making good in Chesham (HP5, HP6, HP7) and the streets around it. Chesham is around 8.1 miles from High Wycombe, and we cover both. Each job is designed by a structural engineer and approved through local building control before work begins.

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.
  • 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.
  • 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.
  • 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.

From survey to sign-off in Chesham

  1. Survey in Chesham

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  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. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building control and neighbours in Chesham

For Chesham, 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.

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

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

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.

Can you work on older or listed homes in Chesham?

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.

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.

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.
