About our temporary works & propping service in Cornwall
Temporary works and propping are the short-term supports that carry floors, walls and roof loads while a structural wall is taken out or a beam is put in. Adjustable steel props, timber spreaders and steel needles pass the weight safely down to the ground until the permanent steel is installed, packed tight and able to take the load itself.
Temporary works & propping are one of the most common structural jobs in homes across Cornwall. Coverage takes in Camborne, Falmouth and Redruth and everywhere in between. Every job starts with a survey visit, then calculations from a structural engineer, so the steel suits the house in front of us rather than a rule of thumb.
Key points for your project
- 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.
- 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.
- 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.
- 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.
- 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.
Four stages, one team
Survey in Cornwall
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 Cornwall
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 Cornwall?
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 much do temporary works & propping cost in Cornwall?
As a guide, budget £150–£520 including VAT for temporary works and propping in Cornwall, based on published UK cost guides adjusted for prices in the South West (+3%). 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.
Does temporary propping need building control approval?
Not on its own, but the structural work it supports usually does. Removing a load-bearing wall or inserting a beam needs building regulations approval in England, Wales and Northern Ireland, and a building warrant in Scotland. The propping arrangement normally forms part of the engineer's calculations sent with that application.
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.
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.
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.
