Steel beam installation, rsj and structural alterations in Putney. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Putney, from the bay-fronted Victorian terraces off the Upper Richmond Road to the Edwardian homes and riverside properties near the Thames. With more than 30 years of structural experience in SW15, we open up load-bearing walls safely and see every beam through to building control sign-off.

The typical Putney terrace has a load-bearing wall between the two reception rooms and another between the kitchen and the rear closet wing. Taking either out to create a single open space needs a steel beam, sized by a structural engineer, bearing onto padstones at each end. Before we cut anything, we install temporary propping to carry the floor and the wall above, then demolish in careful, staged sections rather than all at once.
Because these SW15 houses share party walls and chimney stacks with the neighbours, the beam often bears into masonry that is jointly owned. That brings the Party Wall etc. Act 1996 into play, so we help you serve the correct notices on adjoining owners in good time. Every RSJ we fit is inspected and signed off by building control under the building regulations, giving you a clean paper trail for the future.
No two Putney houses carry load in quite the same way. A double-storey terrace with rooms above, a loft conversion overhead or a wide side-return infill all change the size of steel required, so we never guess. We work from a structural engineer's calculations and specify the beam, the bearing length and the padstones accordingly, whether that is a single RSJ or a goalpost frame with columns.
Solid Victorian brickwork behaves differently from later cavity walls, and the closet wings on these terraces often sit on shallow foundations. We check the bearings, pad out where the masonry is weak and make sure the new steel is properly bedded and fire-protected. Once the beam is in and the props come out, we make good the openings, plaster the reveals and leave the room ready for the next stage of your project.
Putney homeowners choose GS Renovation because we treat steel beam work as engineering, not guesswork. One team handles the propping, the safe demolition, the beam and the making good, working to the engineer's calculations and to building control. With 30+ years in SW15 party wall terraces, we keep the job safe, tidy and fully documented from start to sign-off.
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 Putney 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.
We will give you an honest timescale for RSJ and steel beam installation in Putney after surveying your home. Most projects run on a clear weekly programme, and we tell you up front about any lead times on materials or approvals.

Removing a load-bearing wall in Putney 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 Putney'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. In most Putney terraces the wall you want to open sits on, or the beam bears into, a party wall shared with your neighbour, so the Party Wall etc. Act 1996 applies. You must serve written notice on the adjoining owners before work starts. We guide you through the timing and, separately, arrange building control sign-off under the building regulations.
