Planning RSJ installation in Durham
We cover RSJ installation in Durham (DH1) and the streets around it. Durham is around 11.7 miles from Sunderland, and we cover both. Each job is designed by a structural engineer and approved through Durham County Council before work begins.
People still call almost any steel beam in a house an RSJ, even though the sections fitted today are usually universal beams with parallel flanges. Whatever the name, the job is the same: a length of structural steel, made to an engineer's specification, carrying floors, walls or roof over a space where support used to be.
Worth knowing before you start
- Packing is what makes the beam work. Steel shims and dry-pack mortar fill the gap between the top flange and the structure above, so the load transfers onto the steel without the floor or wall settling down onto it.
- An RSJ inside a home commonly needs 30-minute fire resistance where it supports elements of structure. Fire-rated plasterboard boxing is the usual method, with intumescent paint used when the beam is to remain visible.
- Sometimes two beams are bolted side by side with spacers, either to carry a thick wall or to fit through a tight space. Bolt spacing and spacer type come from the engineer's design rather than being decided on site.
- RSJ originally meant a rolled steel joist with tapered flanges. Most beams supplied for homes today are universal beams with parallel flanges, but the term RSJ has stuck, and builders, engineers and building control all understand what it means.
- Steel for internal use is normally delivered with a primer coat to protect it during installation. Beams in damp positions, within external walls or exposed outside need a more robust coating or galvanising, as the engineer specifies.
How the job runs in Durham
Survey in Durham
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 Durham County Council, 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.

| Load-bearing wall removal with steel beam | £1,850–£4,650 | Typical internal wall up to about 4 m: calculations, building control, propping, steel, padstones, fitting, fire protection and making good |
| Temporary works and propping | £140–£460 | Props, spreaders, needles and sole plates for a typical opening, installed and struck |
| Fire protection to a steel beam | £140–£560 per beam | Fire-rated board boxing or an intumescent coating system as specified |

Building rules for Durham
For Durham, building control is provided by Durham County Council, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
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.

RSJ installation in Durham: your questions
Do I need a party wall agreement for RSJ installation in Durham?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
Do you also work near Durham?
Yes. We also cover nearby towns including Chester-le-Street, Houghton-Le-Spring, Stanley and Washington.
What does RSJ stand for?
RSJ stands for rolled steel joist. It was the name for a hot-rolled I-shaped steel section with tapered flanges, and it is still used loosely for any steel beam in a house. Most steels fitted in homes today are universal beams, which do the same job with parallel flanges.
What is included in an RSJ supply and fit price?
Our itemised written quote sets out the calculations, building control, steel and fabrication, delivery, lifting, padstones, propping, labour, fire protection and making good as separate lines. Once the specification and scope are agreed, the price is fixed in writing, so you know the full cost before work starts.
Do I need building regulations approval to fit an RSJ?
Yes, when the RSJ carries structural load such as a wall, floor or roof. In England and Wales building control is notified or approved beforehand, Northern Ireland needs a council application before work starts, and Scotland requires a building warrant first. A completion certificate confirms sign-off at the end.
What happens at the survey visit in Durham?
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.
