Steel beam installation, rsj and structural alterations in Addiscombe. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Addiscombe, where CR0 is dominated by bay-fronted Victorian and Edwardian terraces with rear closet wings and side returns. With more than 30 years of structural work in Croydon, we remove load-bearing walls safely, from the ground floor of a two-up two-down to a full through-lounge.

The wall between the two reception rooms in an Addiscombe terrace is almost always load-bearing, carrying the floor joists above and, in many cases, a chimney breast and stack. Before anything is touched, we have a structural engineer calculate the load and specify the correct steel, whether that is a single RSJ or a pair of beams bolted together for a wider opening across a bay-fronted front room.
On site we install temporary propping to take the weight, then carry out staged demolition so nothing is left unsupported. The beam bears onto concrete or engineered padstones at each end, spreading the load into the solid brickwork. Building control inspects the padstones and the finished steel, and we keep the property watertight and clean while an Addiscombe family stays living upstairs.
Because Addiscombe's terraces share a party wall with the house next door, any beam that bears into that dividing wall brings the Party Wall Act into play. We flag this early, help you serve the correct notice on your neighbour and coordinate with their surveyor if one is appointed, so the steelwork proceeds without a dispute holding up the job.
Chimney breast removal is a common companion to this work in CR0. Where a homeowner wants to reclaim the space in a closet wing or bedroom, the stack above has to be supported on a gallows bracket or a beam rather than left hanging. We size that support with the engineer, get it signed off by Croydon's building control channel and make good the shared wall properly.
Addiscombe homeowners choose GS Renovation because we treat steelwork as structural engineering, not guesswork. Every beam is sized by an engineer, propped safely, seated on proper padstones and signed off by building control, with party wall notices handled where the shared wall is affected. Thirty years across Croydon means we know how these terraces are built.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
FAQ
The cost of RSJ and steel beam installation in Addiscombe depends on the size of the property, the specification and the scope of work. GS Renovation provides free, detailed and itemised quotations for every Addiscombe project. Call 07472 424 226 or email info@gsrenovationltd.co.uk for a no-obligation estimate. 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.

Removing a load-bearing wall in Addiscombe does not normally need planning permission, but it always needs building regulations approval, a structural engineer's calculations and building control sign-off. Where the wall is shared with a neighbour, the Party Wall Act may also apply. We manage all of it.
Yes. A large share of Addiscombe's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
Usually yes. Most Addiscombe terraces share a party wall with the neighbouring house, and if your new beam bears into that wall or you cut into it, the Party Wall Act applies. You serve notice on your neighbour before work starts. We identify this at survey stage and guide you through the notice, so the steelwork is not delayed.
Yes. We work throughout Addiscombe and the CR0 area, as well as the surrounding parts of South London. Contact us on 07472 424 226 to confirm we cover your street.
