About our temporary works & propping service in Ruislip
For homes in Ruislip and the HA2, HA4, HA5, HA6 and UB5 districts, we handle temporary works & propping from survey to sign-off. Our coverage runs across London, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.
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.
Things to plan for
- 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.
- Propping normally goes in on the first morning and stays until the beam is carrying. For a typical opening that is a few days, and longer where padstone mortar needs time to cure before the load is transferred onto it.
- 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.
- 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.
- 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.
From survey to sign-off in Ruislip
Survey in Ruislip
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.

Approvals in Ruislip
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.
Questions about temporary works & propping in Ruislip
Do you cover Ruislip for temporary works & propping?
Yes. We carry out temporary works & propping in Ruislip and the HA2, HA4, HA5, HA6 and UB5 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do you also work near Ruislip?
Yes. We also cover nearby towns including Northolt, Uxbridge, Harrow and Hayes.
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.
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.
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.
What happens at the survey visit in Ruislip?
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.
