About our temporary works & propping service in Amersham
Need temporary works & propping in Amersham? We also work in nearby High Wycombe, roughly 6.3 miles away. We survey the property, arrange the engineer's design, deal with local building control, fit the steel and make good, all under one quote for HP5, HP6, HP7 and HP8 addresses.
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
- In older homes with lime mortar and soft bricks, the masonry above an opening can loosen once it is cut. The engineer may call for closer needle spacing or fuller support, because old walls can arch or drop in ways a modern wall does not.
- 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.
- 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.
- 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.
What happens, step by step
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.

Approvals in Amersham
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.
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.

Local questions answered
What happens at the survey visit in Amersham?
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.
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 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.
