Steel beam installation, rsj and structural alterations in Kingston upon Thames. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and structural steel across Kingston upon Thames, from the bay-fronted Victorian terraces of Surbiton to the substantial period houses near Richmond Park. With over 30 years of experience across KT1, KT2, KT3, KT5 and KT6, we remove load-bearing walls safely, sizing every beam to an engineer's specification.

The dividing wall between the two front rooms of a Kingston terrace is usually load-bearing, carrying the floor and often a chimney breast above. To open it up we install a steel beam, sized by a structural engineer to the span and load, bearing onto concrete padstones at each end. We prop the structure temporarily, take the wall down in careful stages, then seat the RSJ and make good before the props come out.
Many terraces in KT5 and KT6 share their side walls and chimney stacks with the neighbouring property, so the work falls under the Party Wall Act. Where a beam bears into a shared wall, we help you serve the correct notice on the adjoining owner before any cutting begins. Every installation is inspected and signed off by building control under Kingston Council, giving you certified structural work and a clear record for any future sale.
Larger projects in KT2 and KT3, such as spanning a full-width rear opening or supporting a loft conversion, often call for heavier steel or paired beams bolted together. The substantial Victorian and Edwardian houses around Surbiton and New Malden carry real weight in their solid brick walls, so we work only to a structural engineer's calculations rather than guesswork. Correct beam depth, padstone size and bearing length all matter for a wall that will stand for decades.
Because we manage the whole sequence, there is no gap between the engineer, the steel supplier and the trades on site. We coordinate temporary support, protect floors and finishes in an occupied home, and fireproof the exposed steel where the regulations require it. Once the RSJ is in and inspected, our team plasters, levels and reinstates so the finished room shows no sign of the beam, only the open, connected space you wanted.
Kingston homeowners choose GS Renovation because steel work is our flagship trade, backed by 30+ years across KT1 to KT6. We handle the engineer's design, the padstones, the propping, the party wall notices and the building control sign-off as one accountable job, working cleanly in occupied period homes and leaving certified, properly finished structure behind.
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 Kingston upon Thames, 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 Kingston upon Thames 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 Kingston upon Thames 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 Kingston upon Thames'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.
Often yes. Many Surbiton and wider Kingston terraces share their side walls and chimney stacks with next door, so cutting a beam bearing into that shared wall is notifiable under the Party Wall Act. You must serve notice on the adjoining owner before work starts. We size the steel with an engineer, arrange the notice and get building control sign-off.
Absolutely. Our team works right across Kingston upon Thames and the KT1 area and neighbouring parts of South West London. Get in touch on 07472 424 226 to check coverage for your address.
