About our temporary works & propping service in Hadley Wood
Our temporary works & propping service in Hadley Wood covers everything from the first visit to the completion paperwork. Our coverage runs across London, so nearby villages are included too. Postcode districts we cover here include EN4, EN5, N14 and N20.
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.
Key points for your project
- 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.
- 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.
- 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.
- 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.
How the job runs in Hadley Wood
Survey in Hadley Wood
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
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.
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 Hadley Wood
For Hadley Wood, 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.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Local questions answered
Do I need a party wall agreement for temporary works & propping in Hadley Wood?
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.
What happens at the survey visit in Hadley Wood?
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.
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.
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.
Does temporary propping need building control approval?
Not on its own, but the structural work it supports usually does. Removing a load-bearing wall or inserting a beam needs building regulations approval in England, Wales and Northern Ireland, and a building warrant in Scotland. The propping arrangement normally forms part of the engineer's calculations sent with that application.
Can you work on older or listed homes in Hadley Wood?
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.
