About our temporary works & propping service in Harlow
Need temporary works & propping in Harlow? The wider Essex area is covered as well. 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 CM17, CM18, CM19 and CM20 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.
Worth knowing before you start
- 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.
- 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.
- 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.
- Typical mistakes include props standing on unsupported floorboards, missing spreaders so one joist takes all the load, and props wound up too hard so the ceiling lifts and cracks. Careful setting out and gradual tightening avoid all three.
- 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.
Four stages, one team
Survey in Harlow
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 rules for Harlow
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
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.

Temporary works & propping in Harlow: your questions
Do you cover Harlow for temporary works & propping?
Yes. We carry out temporary works & propping in Harlow and the CM17, CM18, CM19 and CM20 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Can you work on older or listed homes in Harlow?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
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.
Can I hire props and support a wall myself?
Props can be hired, but propping a structure is skilled work with serious consequences if it goes wrong. The arrangement should come from an engineer's design, and the loads, floor strength and sequence all need checking. Structural propping should be left to a competent team working to that design.
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.
How much do temporary works & propping cost in Harlow?
As a guide, budget £160–£530 including VAT for temporary works and propping in Harlow, based on published UK cost guides adjusted for prices in the East of England (+6%). 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.
