About our temporary works & propping service in Llangefni
For homes in Llangefni and the LL60 and LL77 districts, we handle temporary works & propping from survey to sign-off. The wider Anglesey area is covered as well. 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.
What to expect
- 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.
- 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.
- In the UK, temporary works are generally managed following BS 5975, the code of practice for temporary works procedures. On bigger jobs that means a named coordinator, a written design and checks before props are loaded or taken out.
- 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.
- 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.
Four stages, one team
Free visit
A short visit to Llangefni 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 the application or notice to Isle of Anglesey County Council under the Building Regulations as they apply in Wales, before work starts.
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 rules for Llangefni
Welsh building regulations treat beams and new openings as controlled building work. We apply to Isle of Anglesey County Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Questions about temporary works & propping in Llangefni
How much do temporary works & propping cost in Llangefni?
As a guide, budget £140–£460 including VAT for temporary works and propping in Llangefni, based on published UK cost guides adjusted for prices in Wales (-9%). 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 stay at home while the work is done in Llangefni?
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.
Can props damage my floor?
They can if they are set up carelessly. Each prop concentrates load on a small area, so sole plates or boards are used to spread it, and on suspended timber floors props may be carried through to the ground below. Floor coverings are protected with boards and sheeting before any prop goes in.
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.
What happens at the survey visit in Llangefni?
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.
