Steel beam installation, rsj and structural alterations in Orpington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and structural steel beams throughout Orpington, where the BR6 housing stock is dominated by 1930s semi-detached and interwar suburban homes on generous plots. With more than 30 years of structural experience across Bromley, we open up load-bearing walls safely, from ground floor knock-throughs to chimney breast removals in these solid family houses.

The wall between the front reception and rear dining room of a typical Orpington interwar semi almost always carries load from the floors and roof above. Before any demolition, our structural engineer calculates the beam size and specifies the padstones it must bear onto. We then install temporary propping, remove the masonry in careful staged sections and lift the RSJ into position so the structure above stays fully supported throughout.
Because so many Orpington houses in BR6 are semi-detached, the dividing wall between you and your neighbour is a shared party wall. Where the beam bears into that wall, the Party Wall Act applies and formal notices must be served before work starts. We flag this at the survey stage, help you serve the correct notices in good time and coordinate the steelwork so the schedule is not held up.
Steel is only as safe as its bearings. In the 1930s cavity and solid brickwork common across Orpington, we set the RSJ ends onto concrete or high-strength padstones that spread the load into sound masonry rather than crushing older brick. Every beam is fitted level, packed and connected exactly as the engineer's drawings require, then fire-protected where the regulations call for it.
Structural steelwork is controlled under building regulations, not planning permission, so the project runs through Bromley Council building control or an approved inspector. We arrange the inspections, present the engineer's calculations and drawings, and book the beam sign-off before anything is plastered over. You finish with a compliant, documented installation and a completion certificate that protects the value of your Orpington home when you come to sell.
Orpington homeowners choose GS Renovation because we manage the whole structural job under one roof, from engineer's calculations and padstone design to propping, safe demolition and building control sign-off. Our 30-plus years working on BR6 interwar semis means we understand the shared party walls and older brickwork, and we serve the right notices so the work is safe and fully compliant.
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 Orpington 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 Orpington 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.

Removing a load-bearing wall in Orpington 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 Orpington's homes are 1930s and interwar properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.
Usually yes. Most Orpington homes are 1930s semis, so the wall you share with your neighbour is a party wall. If the new steel beam bears into that wall, the Party Wall Act applies and you must serve notice on the adjoining owner before work begins. We identify this at survey and guide you through serving the correct notices so the steelwork is not delayed.
We do. GS Renovation covers all of Orpington and the BR6 area and the wider South East London. Call 07472 424 226 and we will confirm we work on your road.
