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.
The Victorian terraces around Charlton Park were built in soft London stock brick laid in lime mortar, which behaves nothing like modern brickwork in cement. Lime is forgiving and lets a wall move, but it is weaker in local compression, so a beam bearing straight onto old brickwork can crush it. The engineer's padstone is sized for that, and it is normally bedded on a wider spread of sound bricks than a newer house would need.
Foundations in this stock are shallow, often little more than a corbel of brick on clay, so we avoid overloading a short length of wall while the props are up. Cutting is done carefully rather than with heavy percussion, since vibration opens joints in lime mortar and cracks plaster in the next room. Where the wall is in poor condition we rebuild the bearing zone in engineering brick first, on the engineer's instruction, before the steel arrives.
Charlton homeowners choose GS Renovation because steel work is our flagship trade, not a sideline. We handle the engineer's calculations, the propping 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.

FAQ
Check what has been left out before deciding. Cheap RSJ and steel beam installation quotations in Charlton tend to be rather light on approvals and reinstatement, and work started without Royal Borough of Greenwich sign-off becomes expensive when the SE7 property is sold. GS Renovation includes both as standard. We would rather lose the job than win it by omission. Ring 07472 424 226 and GS Renovation will explain what a complete Greenwich quotation should contain, and what it should not. 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.
In most cases you can, and we plan the Charlton works around it. The question is whether RSJ and steel beam installation takes out the kitchen, the bathroom or the heating at your SE7 property for any length of time, and the programme shows exactly when. GS Renovation phases the Greenwich job room by room where staying put matters. Sometimes moving out for one week is simply easier. Ring 07472 424 226 and GS Renovation will describe how an SE7 household in Charlton usually manages.
We tell you immediately, price the fix, and get your agreement before continuing. Problems on an RSJ and steel beam installation job usually surface when a late Victorian and Edwardian SE7 property is opened up, and hiding them helps nobody. GS Renovation sets out the effect on the Charlton programme and on the cost in writing. Work resumes once you have decided, not before. Ring 07472 424 226 to hear how Greenwich variations are agreed. Nothing at SE7 proceeds without your written approval in Charlton.
No, internal steelwork does not engage planning in a Charlton home, but it always needs building regulations approval, a structural engineer's calculations and Royal Borough of Greenwich sign-off. Where the wall is shared with a neighbour the Party Wall Act applies. GS Renovation manages all of it for your SE7 property.
It changes the making good more than the structural element. Solid-wall Victorian terraces with original chimney breasts and suspended timber floors rarely have square openings or regular floors, so RSJ and steel beam installation at an SE7 property takes longer in plaster and joinery than in a modern house. GS Renovation shows that as a separate line on the Charlton quotation. The survey that establishes it is free. GS Renovation will explain on 07472 424 226 how RSJ and steel beam installation is actually priced at an SE7 address in Charlton itself.
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.
Anywhere in the area, and there is no minimum job size. RSJ and steel beam installation enquiries reach GS Renovation from across Charlton and South East London, and each gets a free survey at the SE7 property and a written quotation afterwards. Building control is coordinated with Royal Borough of Greenwich where the work requires it. Email info@gsrenovationltd.co.uk to get started. Nothing is owed whether you proceed or not. Small jobs at an SE7 address are just as welcome here.
