Steel beam installation, rsj and structural alterations in Lambeth. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Lambeth, from the Georgian townhouses of Kennington to the Victorian terraces around Clapham Common. With over 30 years of structural experience in SE11, SW4 and SW9, we open up period homes safely, with beams sized by a structural engineer and signed off by building control.

Lambeth's Georgian and Regency townhouses were built with solid brick walls and internal load-bearing partitions, so removing a wall to create flow means transferring real weight onto a new steel. In SW2 and SE24 we work with your structural engineer to size the RSJ, cast or supply padstones at each bearing, and install temporary propping before any masonry comes down. Every stage is planned so the structure above stays supported throughout.
Because many Lambeth homes sit within conservation areas or carry listed status, we keep steelwork discreet, dropping beams into the ceiling line where head height allows and boxing them cleanly afterwards. We stage demolition carefully in occupied houses around Brixton and Streatham, protecting original cornicing and floors. Once the beam is bearing correctly on its padstones, building control inspects the work before we close everything up.
A large share of Lambeth's terraces and semis share a party wall with the neighbouring house, and chimney breasts and dividing walls often sit right on that boundary. Where your beam bears into a shared wall, the Party Wall Act applies, so we help you serve the correct notices on adjoining owners in good time. This keeps SW8 and SE27 projects lawful and avoids disputes once the drilling and cutting begin.
We handle the practical side too, from propping the floors above to protecting the neighbour's side of the wall during breaking out. Our teams work to a sequence agreed with building control, so inspections happen at the right moments and nothing is hidden. Whether you are removing a chimney breast in Vauxhall or a spine wall in Clapham, the steel is specified, installed and certified to keep your home sound for decades.
Homeowners across Lambeth trust GS Renovation because we treat structural work as the serious job it is. One team handles the engineer's design, the propping, the party wall notices and the building control sign-off, working tidily in occupied period homes. With 30+ years across SE11, SW4 and SW9, we deliver steelwork that is safe, certified and built to last.
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 Lambeth 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.
A straightforward Lambeth project can be done in a couple of weeks, while a larger RSJ and steel beam installation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.
Because we manage every trade in-house, your Lambeth project stays consistent and accountable from first fix to finish. Add transparent pricing, full insurance and real aftercare, and it is easy to see why Lambeth clients recommend us.
Removing a load-bearing wall in Lambeth 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 Lambeth's homes are period, Georgian and listed properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as conservation and listed-building rules, solid walls and original period features, so the result suits the building and meets building control.
Very often, yes. Many Clapham terraces share a party wall with next door, and if your steel beam bears into that shared wall or you cut a chimney breast on it, the Party Wall Act applies. You must serve notice on the adjoining owner before work starts. We guide you through the notices and coordinate the timing with your structural engineer and building control.
We cover the whole of Lambeth and the SE11 area and the surrounding South London. If you are nearby and not sure, just call 07472 424 226 and we will tell you straight away.
