Planning temporary works & propping in Flint
Flint has a mix of housing, and temporary works & propping need a slightly different approach in each. Our coverage runs across Flintshire, so nearby villages are included too. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
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.
Things to plan for
- In older homes with lime mortar and soft bricks, the masonry above an opening can loosen once it is cut. The engineer may call for closer needle spacing or fuller support, because old walls can arch or drop in ways a modern wall does not.
- Typical mistakes include props standing on unsupported floorboards, missing spreaders so one joist takes all the load, and props wound up too hard so the ceiling lifts and cracks. Careful setting out and gradual tightening avoid all three.
- 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.
- 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.
- 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.
Four stages, one team
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.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit the application or notice to Flintshire County Council under the Building Regulations as they apply in Wales, before work starts.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

| Load-bearing wall removal with steel beam | £1,800–£4,550 | Typical internal wall up to about 4 m: calculations, building control, propping, steel, padstones, fitting, fire protection and making good |
| Chimney breast removal (ground floor) | £1,350–£2,750 | Ground-floor breast removed, steel to support the breast above, building control and making good |
| Lintel replacement | £360–£1,090 per lintel | Propping, removing the old lintel, new lintel set on beds and brickwork made good |
Figures include our approximate regional adjustment for prices in Wales (-9%) and are rounded. How these figures are worked out.
Approvals in Flint
Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Flint the application goes to Flintshire 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.
Questions about temporary works & propping in Flint
What happens at the survey visit in Flint?
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.
Do you also work near Flint?
Yes. We also cover nearby towns including Deeside, Buckley, Hawarden and Ruthin.
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 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.
