About our temporary works & propping service in Truro

Our temporary works & propping service in Truro covers everything from the first visit to the completion paperwork. We also cover the surrounding towns and villages in Cornwall. Postcode districts we cover here include TR1.

The moment a load-bearing wall is cut, whatever it was holding needs another route to the ground. Temporary works provide that route. Done well, nothing above moves, ceilings stay intact and the floor below is not overloaded. Done badly, it is where structural work goes wrong.

Worth knowing before you start

  • Propping costs depend on how many props and needles the load calls for, how long they stay in, whether a separate temporary works design is required, and whether props must continue through a floor to reach solid ground.
  • Needle holes leave neat square gaps in the wall above the new beam. Once the props are out, these are filled with brick or block and mortar, then plastered over with the rest of the making good.
  • Every prop delivers a concentrated load that has to go somewhere. Before any are set up, the floor beneath is checked, because a suspended timber floor or a thin slab may not take that load without extra support carried down to the ground.
  • When an external wall is propped, the opening is sheeted against rain and the house is kept secure overnight. Where props stand outside, ground conditions, drains and access paths are taken into account before they are set up.
  • In the UK, temporary works are generally managed following BS 5975, the code of practice for temporary works procedures. On bigger jobs that means a named coordinator, a written design and checks before props are loaded or taken out.

What happens, step by step

  1. Survey in Truro

    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 Cornwall Council, 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 rules for Truro

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 Cornwall 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.

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.

Questions about temporary works & propping in Truro

Do you cover Truro for temporary works & propping?

Yes. We carry out temporary works & propping in Truro and the TR1 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Can you work on older or listed homes in Truro?

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.

Can I hire props and support a wall myself?

Props can be hired, but propping a structure is skilled work with serious consequences if it goes wrong. The arrangement should come from an engineer's design, and the loads, floor strength and sequence all need checking. Structural propping should be left to a competent team working to that design.

Can I stay in my house while it is propped?

Usually, yes. The props take up space in the rooms either side of the work, so those rooms will be out of use, but the rest of the house can be lived in as normal. The props must never be moved, knocked or adjusted by anyone other than the installation team.

How long do props have to stay in after a beam is fitted?

Until the permanent steel is packed tight and able to carry the load. That includes time for the padstone and packing mortar to gain enough strength, which depends on the mix and the weather. On a typical opening, props are in for a few days before being released gradually.
