What temporary works & propping involve in Ystradgynlais
Planning temporary works & propping in Ystradgynlais? Our team covers SA9 and the streets around them. The wider Powys area is covered as well. You get one written quote for the calculations, approvals, propping, steel and making good.
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
- Props take up floor space for the length of the job, usually in the rooms on both sides of the wall. Furniture needs moving back, and nobody else in the house should knock, adjust or hang anything from the props.
- Propping normally goes in on the first morning and stays until the beam is carrying. For a typical opening that is a few days, and longer where padstone mortar needs time to cure before the load is transferred onto it.
- 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.
- 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.
- 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.
Four stages, one team
Free visit
A short visit to Ystradgynlais to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit the application or notice to Powys County Council under the Building Regulations as they apply in Wales, before work starts.
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 Ystradgynlais
Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Ystradgynlais the application goes to Powys County 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.
Temporary works & propping in Ystradgynlais: your questions
Do you cover Ystradgynlais for temporary works & propping?

Do I need a party wall agreement for temporary works & propping in Ystradgynlais?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
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.
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.
Can props damage my floor?
They can if they are set up carelessly. Each prop concentrates load on a small area, so sole plates or boards are used to spread it, and on suspended timber floors props may be carried through to the ground below. Floor coverings are protected with boards and sheeting before any prop goes in.
How much do temporary works & propping cost in Ystradgynlais?
