About our RSJ installation service in Mansfield
If you live in Mansfield, RSJ installation can usually be planned and priced after a single survey visit. It sits about 12.6 miles from Nottingham, which we also cover. We cover NG17, NG18 and NG19, and we fix the price in writing once the layout and scope are agreed.
We supply and fit the steel from start to finish. That includes arranging the calculations, having the beam fabricated with the right end plates, holes and primer, getting it into the property, setting it on its bearings, and packing it so it takes the load. Building control, propping and making good sit in the same itemised quote.
Key points for your project
- 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.
- 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.
- Heavy steels are raised with suitable lifting equipment rather than by hand alone. Manual handling is planned so nobody carries more than is safe, and the lift is coordinated so the beam goes up level onto both bearings together.
- 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.
- 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.
What happens, step by step
Survey in Mansfield
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.
How much should I budget in Mansfield?
As a guide, budget £780–£2,450 per beam including VAT for rSJ supply and fit (single beam) in Mansfield, based on published UK cost guides adjusted for prices in the East Midlands (-2%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| RSJ supply and fit (single beam) | £780–£2,450 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
| Load-bearing wall removal with steel beam | £1,950–£4,900 | Typical internal wall up to about 4 m: calculations, building control, propping, steel, padstones, fitting, fire protection and making good |
| Temporary works and propping | £150–£490 | Props, spreaders, needles and sole plates for a typical opening, installed and struck |
| Structural calculations for a beam | £240–£740 | Site measure or photos, beam and padstone design and calculations for building control |
Figures include our approximate regional adjustment for prices in the East Midlands (-2%) and are rounded. How these figures are worked out.
Building control and neighbours in Mansfield
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.

RSJ installation in Mansfield: your questions
Who approves RSJ installation in Mansfield?
Structural work in Mansfield 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.
Can I stay at home while the work is done in Mansfield?
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.
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.
How heavy is an RSJ and how is it lifted?
Weight varies widely with the section and length, from beams a small team can carry to steels needing mechanical lifting. The lift is planned at the survey, using enough people, trolleys and suitable lifting equipment so the beam goes up safely and level onto both bearings.
Who decides what size RSJ I need?
A structural engineer. The size depends on the span, the loads from floors, walls and roof above, how stiff the beam needs to be and how its ends are supported. We arrange calculations from a qualified engineer, or fit to calculations you already have, rather than guessing a size.
Can you work on older or listed homes in Mansfield?
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.
