Steel beam installation, rsj and structural alterations in Wallington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation has spent more than 30 years removing walls and installing steel across Wallington's SM6 streets. The bay-fronted Victorian and Edwardian terraces here, with their rear closet wings and side returns, were built with load-bearing internal walls, so opening them up safely means a properly sized RSJ, not guesswork.

Every beam we install begins with a structural engineer's calculations, which size the RSJ to the load it will carry and specify the padstones it bears onto at each end. On a typical Wallington terrace we set up temporary propping first, then work through a staged, controlled demolition so the wall never comes down before the new steel is safely in place and packed tight to the underside of the floor above.
Because the terraces along Wallington's SM6 roads share party walls, and because chimney stacks frequently sit within that shared masonry, removing a wall often triggers a notice under the Party Wall Act to your neighbour. We handle that process alongside the building control application, so the structural work is inspected and signed off correctly. Cutting a beam into a party wall demands care, and our thirty years locally means we know how these houses are built.
The most common request we get in Wallington is to knock the two reception rooms into one, joining the bay-fronted front room to the middle room where the chimney breast and dividing wall stand. That wall almost always carries load from the floor and roof above, so it cannot simply be taken out. A steel beam, sized by an engineer and supported on padstones, replaces the wall and keeps the structure sound.
We also open up rear closet wings and remove kitchen walls to create through-lounges and kitchen-diners. Whatever the layout, we prop the structure temporarily, protect the rest of the house from dust and debris, and take the wall down in stages. Building control inspects the beam and its bearings before we plaster over, so you have documented sign-off that the work meets the regulations. Most single-beam jobs run to one or two weeks.
Wallington homeowners choose GS Renovation because we manage the whole job, from the engineer's drawings and the Party Wall notice to the propping, the steel and the building control sign-off. There is no juggling separate trades. With more than 30 years across SM6 and the neighbouring Sutton and Carshalton streets, we know these terraces and remove their walls cleanly and safely.
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
Pricing RSJ and steel beam installation in Wallington comes down to the size of the job, the specification you choose and the condition of the property. Rather than guess, we survey and give you a fixed, itemised quote you can rely on. Call 07472 424 226. 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.
Most RSJ and steel beam installation projects in Wallington take between two and eight weeks depending on the scope and whether structural work is involved. We provide a clear programme before work begins so you know exactly what to expect.

Removing a load-bearing wall in Wallington 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 Wallington'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.
Very possibly. Most Wallington terraces in SM6 share a party wall with the house next door, and if your steel beam will bear into that shared wall or you are working close to it, the Party Wall Act requires you to serve notice on your neighbour. We prepare and manage this alongside the building control application, so the whole process is handled correctly from the start.
Absolutely. Our team works right across Wallington and the SM6 area and neighbouring parts of South London. Get in touch on 07472 424 226 to check coverage for your address.
