What temporary works & propping involve in Castlereagh
Castlereagh has a mix of housing, and temporary works & propping need a slightly different approach in each. Our coverage runs across Belfast, 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.
Propping is included in every structural job we quote, and we can also provide it as a separate service where a wall, lintel or chimney needs supporting while other work goes on. The layout of props, needles and spreaders follows the engineer's calculations or a temporary works design for the job.
Worth knowing before you start
- 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.
- 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.
- 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.
- Props and needles cannot go where pipes, cables or flues run. Their positions are checked against services before any holes are cut, and anything in the way is isolated or rerouted first by the appropriate trade.
Four stages, one team
Survey in Castlereagh
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.
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.
Building control
A full plans application or building notice goes to Belfast City Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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 Castlereagh
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Castlereagh that is Belfast City Council. We submit a full plans application or building notice before work starts and book the inspections.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.

Questions about temporary works & propping in Castlereagh
Can I stay at home while the work is done in Castlereagh?
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 Castlereagh?
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.
Do I need a temporary works design for my job?
Not always. For a simple single opening, the propping shown in the engineer's calculations is often enough. Bigger or more complex jobs, such as removing several walls, supporting chimney stacks or replacing a shopfront beam, may need a separate temporary works design from an engineer, following the BS 5975 approach.
Why do you need props to remove a wall?
Because the wall is holding up weight that still has to be supported while it is gone. Props and needles carry the floors, walls or roof above down to the ground until the new steel beam is fitted, packed and taking the load. Without them, the structure above could drop, crack or, at worst, collapse.
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.
Do I need a party wall agreement for temporary works & propping in Castlereagh?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
