Steel beam installation, rsj and structural alterations in Beckenham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Beckenham, from the bay-fronted Victorian and Edwardian terraces near Beckenham Place Park to the interwar semis of BR3. With over 30 years of experience in South East London, we remove load-bearing walls safely, with every beam sized by a structural engineer and signed off by Bromley Council building control.

The dividing wall between the front and rear reception in a Beckenham terrace is almost always load-bearing, carrying the floor above and often a chimney stack. Before any demolition, our structural engineer calculates the load and specifies the right RSJ, along with the padstones it will bear onto. We install temporary propping to support the structure, then remove the wall in safe, staged sections rather than taking it out all at once.
Because these terraces share a party wall with the neighbouring property, and chimney breasts frequently sit within it, the Party Wall Act usually applies. We help you serve the correct notices on adjoining owners before work begins in BR3. Once the beam is seated on its padstones and the propping comes down, Bromley Council building control inspects the installation and issues sign-off, giving you a documented, compliant result.
Getting the bearing right matters most in older Beckenham stock. The solid brick walls of a Victorian terrace and the cavity walls of a 1930s Beckenham semi behave differently under load, so the padstone design and the beam bearing are tailored to each property. We use concrete or engineered padstones sized to spread the point load safely into the existing brickwork, which avoids cracking or settlement in the masonry below the new opening.
Temporary propping is planned before we touch a single brick. We support floors and any masonry above with adjustable props and needle beams where required, keeping the house stable while the opening is formed. This staged approach protects the original features Beckenham owners want to keep, such as cornicing and picture rails, and it lets us work cleanly in a home that is often still occupied during the project.
Beckenham homeowners choose GS Renovation because we treat steelwork as a structural discipline, not a quick knock-through. We coordinate the engineer, the padstones, the propping, the party wall notices and the Bromley Council building control inspections as one accountable job. With 30+ years across BR3, we open up period terraces safely and leave you with full documentation.
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
We price each Beckenham project individually, because the cost of RSJ and steel beam installation depends on far more than floor area. After a free survey you receive a clear written breakdown with no hidden extras. Call 07472 424 226 or email info@gsrenovationltd.co.uk. 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 Beckenham 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 Beckenham 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 Beckenham'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. Beckenham terraces share a party wall with the house next door, and internal dividing walls often tie into it or contain a shared chimney breast. Under the Party Wall Act you must serve notice on the adjoining owner before cutting into that wall for a beam. We guide you through the notices and timing so the steelwork stays fully compliant.
We cover the whole of Beckenham and the BR3 area and the surrounding South East London. If you are nearby and not sure, just call 07472 424 226 and we will tell you straight away.
