Planning temporary works & propping in Sevenoaks
Planning temporary works & propping in Sevenoaks? Our team covers TN13 and TN14 and the streets around them. Sevenoaks is around 14.2 miles from Maidstone, and we cover both. You get one written quote for the calculations, approvals, propping, steel and making good.
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
- 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.
- 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.
- 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.
- 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.
- 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.
From survey to sign-off in Sevenoaks
Free visit
A short visit to Sevenoaks to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
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.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building control and neighbours in Sevenoaks
For Sevenoaks, 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.
Questions about temporary works & propping in Sevenoaks
Do I need a party wall agreement for temporary works & propping in Sevenoaks?

How much do temporary works & propping cost in Sevenoaks?
As a guide, budget £170–£560 including VAT for temporary works and propping in Sevenoaks, based on published UK cost guides adjusted for prices in the South East (+12%). 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.
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.
How long do props have to stay in after a beam is fitted?
Until the permanent steel is packed tight and able to carry the load. That includes time for the padstone and packing mortar to gain enough strength, which depends on the mix and the weather. On a typical opening, props are in for a few days before being released gradually.
Can I stay in my house while it is propped?
Usually, yes. The props take up space in the rooms either side of the work, so those rooms will be out of use, but the rest of the house can be lived in as normal. The props must never be moved, knocked or adjusted by anyone other than the installation team.
