RSJ and Steel Beam Installation Hammersmith and Fulham

Steel beam installation, RSJ and structural alterations in Hammersmith and Fulham. Trusted, professional, 30+ years' hands-on experience.

GS Renovation installs RSJs and steel beams across Hammersmith and Fulham, from the bay-fronted terraces of W6 and W14 to the riverside homes near Bishops Park in SW6. With over 30 years of structural work in the borough, we open up period houses safely, from load-bearing wall removal to building control sign-off.

Steel beams for Hammersmith and Fulham terraces

The Victorian and Edwardian terraces around Fulham Broadway and Shepherd's Bush were built with solid load-bearing masonry, so removing the wall between two reception rooms or opening a rear kitchen means carrying that load on steel. Every beam we fit is sized by a structural engineer to suit the span and the weight above, then set to bear onto concrete padstones so the point loads transfer cleanly into sound brickwork below.

Before any wall comes down we install temporary propping and work through a safe, staged demolition, cutting the pockets, seating the RSJ and pinning up to the underside before the props come out. In these tightly built W12 and SW6 homes we protect floors and stairs, keep dust down and leave the structure ready for plastering, with everything sequenced to keep the house stable throughout.

Party walls and building control in Hammersmith and Fulham

Because these terraces share a party wall with the house next door, and chimney breasts and dividing walls often sit within it, cutting a beam bearing into that shared wall usually triggers the Party Wall Act. you serve the correct notices on adjoining owners in good time, which matters on the closely packed streets of Hammersmith and Fulham where neighbours sit only a brick's width away.

Steel beam work is governed by building regulations rather than planning permission, so we notify Hammersmith and Fulham Council's building control or use an approved inspector. The engineer's calculations, the padstone details and the beam sizes are all submitted, and an inspector checks the bearings and fire protection before sign-off. You finish with a completion certificate that protects the value of your home and any future sale.

Choosing and protecting the right section

People say RSJ, but the section your engineer specifies is usually a universal beam, and occasionally a channel, a hollow section or a pair of beams bolted together with a spacer. The choice follows the span, the load and how much depth the room can give up. A parallel flange universal beam is the ordinary answer in a Fulham terrace; a flitched timber beam sometimes suits a lighter span where a steel would be awkward to get in.

Protection matters as much as the section. Steel arrives with a basic primer that is not a long-term finish, so where a beam sits in or near an external wall in SW6 we specify a proper paint system or galvanising, because a beam that rusts in a damp reveal will jack the brickwork above it. Bearings are damp-proofed, and any exposed steel is fire protected to the thickness the regulations require for the storey it sits in.

FAQ

Frequently Asked Questions about RSJ and Steel Beam Installation Hammersmith and Fulham

What drives the cost of RSJ and steel beam installation in a Hammersmith and Fulham home?

What sits behind the walls drives it far more than the address does. We survey the W6 property, confirm the load path, and only then price RSJ and steel beam installation for your Hammersmith and Fulham home. Older stock across Hammersmith and Fulham adds making good, and awkward access adds labour, so both are itemised rather than absorbed. GS Renovation would rather explain a Hammersmith and Fulham figure than defend it later on site, so ring 07472 424 226 or email info@gsrenovationltd.co.uk first. As a rough guide, RSJ and steel beam installation in London runs roughly £1,500 to £4,000 for the beam itself on a single straightforward opening, covering supply, installation and building control sign-off; a full knock-through including taking the wall out, the structural engineer's fee and making good more typically comes to £2,500 to £6,500 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.

Where does an RSJ bear in a Hammersmith and Fulham terrace?

Into the flank walls, which are usually shared with the houses on either side. On your Hammersmith and Fulham terrace the beam spans between the party walls, so the bearings and the padstones sit in masonry the neighbour also relies on. The engineer specifies the padstone size and the minimum bearing length, and the brickwork at each end is checked for soundness before any pocket is cut.

Who designs the steel for a Hammersmith and Fulham project?

A structural engineer, appointed for the job. We are a contractor and do not produce calculations. The engineer sizes the beam, the padstones and the bearings for the specific opening in your Hammersmith and Fulham property, specifies the temporary propping, and issues the calculations that the building control body assesses. The work on site is then built to that design and inspected against it.

Does a lower ground floor change where a beam can bear in Hammersmith and Fulham?

It can, because the load has to carry on below the room you are working in. Many Hammersmith and Fulham houses have a lower ground floor or a cellar, so a bearing at ground level may sit over a void rather than on solid ground. The engineer follows the load down to whatever is actually beneath it, and where that level is not adequate the design adds support there before the beam above is sized.

What happens to pipes and cables in a Hammersmith and Fulham wall being removed?

They are traced and rerouted before the wall comes down. A dividing wall in a Hammersmith and Fulham house commonly carries sockets, switch drops, a boiler flue or a gas run, and some of it will not appear on any drawing. The wall is scanned and opened carefully, circuits are isolated and diverted by the relevant trade, and the electrical work is certified as part of the job.
