About our temporary works & propping service in Coity

Our temporary works & propping service in Coity covers everything from the first visit to the completion paperwork. Our coverage runs across Bridgend, so nearby villages are included too. Postcode districts we cover here include CF31, CF32 and CF35.

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.

What to expect

  • 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.
  • Adjustable steel props are the workhorse, with timber spreaders on top to share the load across several joists. Steel needles pass through the wall to carry masonry above an opening, and prop head attachments known as masonry support heads support brickwork without needles.
  • The order of work matters. Props go in and are tightened before any masonry is cut, the opening is formed in stages, and the props stay until the permanent steel is packed tight and the bedding mortar has gained enough strength.
  • 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.

What happens, step by step

  1. Free visit

    A short visit to Coity to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit the application or notice to Bridgend County Borough Council under the Building Regulations as they apply in Wales, before work starts.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building control and neighbours in Coity

Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Coity the application goes to Bridgend County Borough Council or a registered building control approver, with the engineer's calculations, and a completion certificate follows the final inspection.

Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Questions about temporary works & propping in Coity

Can you work on older or listed homes in Coity?

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 do temporary works & propping cost in Coity?

As a guide, budget £140–£460 including VAT for temporary works and propping in Coity, based on published UK cost guides adjusted for prices in Wales (-9%). 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.

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.

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 many props do I need to take out a load-bearing wall?

It depends on the span, the weight above and the strength of the floor the props stand on. The engineer's calculations or a temporary works design set the number and spacing. It is not something to guess, because too few props, or props in the wrong place, can let the structure move.

Who approves temporary works & propping in Coity?

Structural work in Coity needs a building control application to Bridgend County Borough Council under the Welsh regulations, with a commencement notice before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
