Steel beam installation, rsj and structural alterations in Surbiton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams throughout Surbiton, from the bay-fronted Victorian and Edwardian terraces off the KT6 streets to the riverside homes near the Thames. With more than 30 years of structural work behind us, we remove load-bearing walls safely and leave your terrace open, bright and properly supported.

The typical Surbiton terrace has a solid masonry wall between the front and rear reception rooms, and a second wall where the original kitchen meets the rear closet wing. Both are usually load-bearing, carrying floor joists and often a chimney stack above. Before any demolition we have a structural engineer calculate the correct RSJ, specify the padstones it will bear onto and confirm how the load transfers down through the existing brickwork to the foundations.
On site we install temporary propping to hold the floors and any masonry above, then carry out staged demolition rather than pulling the wall down in one go. The steel is lifted into position, seated on its padstones and packed tight so there is no settlement. Only once building control has inspected the bearings and the beam do we remove the props and make good the openings around the new steel.
Because Surbiton's terraces are joined, the dividing wall between you and your neighbour is often a shared party wall, and the chimney breasts and stacks frequently sit within it. When your beam bears into that wall, or when you cut a chimney breast back, the Party Wall Act applies and your neighbour must be served the correct notice before work starts. We flag this early so the paperwork runs alongside the engineering rather than holding the job up.
We coordinate the timing so notices are served, the agreed period has passed and any schedule of condition is recorded before steel arrives on site. This keeps you on the right side of the Act and protects the relationship with the house next door. Throughout the KT6 postcode we handle these conversations calmly and factually, so a beam that touches a shared wall never becomes a dispute between neighbours.
Surbiton homeowners choose GS Renovation because we treat steelwork as engineering, not guesswork. We work to the structural engineer's calculations, prop safely, respect the party wall obligations that come with joined terraces, and see building control sign-off through to the end. Over 30 years in South West London means openings that stay level and true for good.
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
There is no fixed price for RSJ and steel beam installation in Surbiton, because so much depends on your property and what you want to achieve. We survey first, then provide a transparent written quotation. Contact GS Renovation on 07472 424 226 for a free 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.
Most RSJ and steel beam installation projects in Surbiton 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.
GS Renovation knows Surbiton's homes and how to renovate them properly. We handle the structure, the services and the finishes, deal with building control for you, and leave you with work that is certified, guaranteed and built to last.
Removing a load-bearing wall in Surbiton 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 Surbiton'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.
Removing an internal load-bearing wall needs building regulations approval and building control sign-off, not planning permission, because you are altering the structure rather than the exterior. A structural engineer sizes the beam, we install it on padstones with proper propping, and building control inspects the bearings. If the wall is a shared party wall, a Party Wall Act notice to your neighbour is also required.
We cover the whole of Surbiton and the KT6 area and the surrounding South West London. If you are nearby and not sure, just call 07472 424 226 and we will tell you straight away.
