Temporary works & propping in Hertfordshire: how it works

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.

From the first survey visit to the completion certificate, we take care of temporary works & propping across Hertfordshire. That includes Hitchin, Borehamwood and Bishops Stortford, plus smaller towns and villages nearby. The engineer sizes the steel, we deal with building control, and our team fits and packs the beam before making good.

Key points for your project

  • 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.
  • 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.
  • 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.
  • 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.

How the job runs in Hertfordshire

  1. 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.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. 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.

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Hertfordshire

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

Who approves temporary works & propping in Hertfordshire?

Structural work in Hertfordshire needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.

What happens at the survey visit in Hertfordshire?

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.

Do I need a temporary works design for my job?

Not always. For a simple single opening, the propping shown in the engineer's calculations is often enough. Bigger or more complex jobs, such as removing several walls, supporting chimney stacks or replacing a shopfront beam, may need a separate temporary works design from an engineer, following the BS 5975 approach.

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 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.

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.

Which towns in Hertfordshire do you cover?

We cover towns including Watford, Hemel Hempstead, Stevenage and St Albans, plus the villages and smaller towns around them.
