Steel beam installation, rsj and structural alterations in Charlton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Charlton, working on the bay-fronted Victorian and Edwardian terraces that line the SE7 streets between Greenwich Park and the river. With more than 30 years of structural experience in the Royal Borough of Greenwich, we remove load-bearing walls safely and open up these period homes without cutting corners.

The dividing wall between the front and rear reception in a Charlton terrace is almost always load-bearing, carrying the floor above and often a chimney stack. Before any demolition we have a structural engineer size the steel, then we set temporary props, cut back in stages and lift the RSJ into place onto concrete or engineering-brick padstones. Every beam we install in SE7 is calculated for the real loads above, never guessed.
Because these houses were built with solid brick walls and shared party walls, careful sequencing matters. We work methodically so the structure above stays supported at all times, protect the rest of the home from dust and debris, and only strike the props once the steel is properly bearing. Building control inspects and signs off the finished installation before we plaster and make good.
Many Charlton terraces share a party wall with the neighbour, and the chimney breast or dividing wall you want to remove often sits within it. Where our steelwork bears into or affects that shared structure, the Party Wall etc. Act 1996 applies and notice must be served on the adjoining owner. We flag this early so the legal side runs alongside the build rather than holding it up.
We explain in plain terms which notices are needed, coordinate with your party wall surveyor where one is appointed, and keep a record of the condition of adjoining rooms. This is standard practice on the terraced stock across SE7, from streets near Charlton village towards Woolwich, and handling it properly protects both you and your neighbour for the long term.
Charlton homeowners choose GS Renovation because steel work is our flagship trade, not a sideline. We handle the engineer's calculations, the propping, the party wall notices and the building control sign-off as one accountable job. With 30+ years across the Royal Borough of Greenwich, we open up SE7 terraces safely and leave the finish neat.
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 Charlton 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.
How long RSJ and steel beam installation takes in Charlton depends on the size of the job, but we always agree a programme before starting and stick to it, keeping you informed from the first day to the last.
Charlton homeowners choose GS Renovation for reliability and quality. We are fully insured, building control compliant where needed, and bring over 30 years of hands-on experience to every RSJ and steel beam installation project, with a single point of contact throughout.
Removing a load-bearing wall in Charlton 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 Charlton'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. In Charlton's Victorian and Edwardian terraces the dividing wall or chimney breast frequently sits within the shared party wall, and where our steel beam bears into or affects it the Party Wall etc. Act 1996 applies, so notice must be served on your neighbour. We identify this at the survey stage and coordinate the notices so your project stays on track.
We cover the whole of Charlton and the SE7 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.
