About our temporary works & propping service in Hounslow
We carry out temporary works & propping in Hounslow, covering the TW1, TW2, TW3, TW4 and TW5 postcode districts. We also cover the surrounding towns and villages in London. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
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
- On larger jobs, a temporary works register or permit records when the props were installed, inspected, loaded and removed. It creates a clear trail showing each stage was checked before the next one began.
- 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.
- For simple openings, the engineer's calculations usually show the propping arrangement. Larger or unusual jobs, such as removing several walls or working beneath chimney stacks, may need a separate temporary works design prepared by an engineer.
- 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.
- 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.
From survey to sign-off in Hounslow
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 a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Hounslow
For Hounslow, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
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 Hounslow
Do you also work near Hounslow?
Yes. We also cover nearby towns including Isleworth, Heston, Richmond and Hanworth.
What happens at the survey visit in Hounslow?
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 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.
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.
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.
Do I need a party wall agreement for temporary works & propping in Hounslow?
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.
