About our temporary works & propping service in Brent
Planning temporary works & propping in Brent? Our team covers HA0, HA1, HA2, HA3 and HA9 and the streets around them. The wider London area is covered as well. You get one written quote for the calculations, approvals, propping, steel and making good.
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.
What to expect
- 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.
- 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.
- 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.
- 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.
- 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 Brent
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.

Figures include our approximate regional adjustment for London prices (+28%) and are rounded. How these figures are worked out.
Building control and neighbours in Brent
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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
Can I stay at home while the work is done in Brent?
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 much do temporary works & propping cost in Brent?
As a guide, budget £190–£640 including VAT for temporary works and propping in Brent, based on published UK cost guides adjusted for London prices (+28%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
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.
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.
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.
What happens at the survey visit in Brent?
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.
