Planning temporary works & propping in Cricklewood
Our temporary works & propping service in Cricklewood covers everything from the first visit to the completion paperwork. The wider London area is covered as well. Postcode districts we cover here include NW2, NW3, NW4, NW6 and NW10.
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
- 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.
- 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.
- 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.
- 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.
- Every prop delivers a concentrated load that has to go somewhere. Before any are set up, the floor beneath is checked, because a suspended timber floor or a thin slab may not take that load without extra support carried down to the ground.
How the job runs in Cricklewood
Survey in Cricklewood
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 Cricklewood
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
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 Cricklewood
Can I stay at home while the work is done in Cricklewood?
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.
How soon can temporary works & propping start in Cricklewood?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
What if props need to go on my neighbour's side of the wall?
Then their agreement is needed first. Where needles pass through a party wall, props may have to stand on the neighbour's side, and in England and Wales that work is normally covered by party wall notices served before work starts. We arrange notices through a party wall surveyor where they are required.
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.
What is needling a wall?
Needling means cutting holes through a wall just above where an opening will go and passing short steel beams, called needles, through them. Each needle is supported on props on both sides, so the masonry above rests on the needles while the wall below is removed and the permanent beam is fitted.
