Steel beam installation, RSJ and structural alterations in Tooting. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Tooting, where the bay-fronted Victorian and Edwardian terraces of SW17 were built with load-bearing walls and shared chimney stacks. With over 30 years of structural work in Wandsworth, we open up these period homes safely, from ground-floor knock-throughs to full rear openings.

The most common structural job in Tooting is taking down the wall between the two front reception rooms, or opening the rear wall into a closet wing. In these SW17 terraces that wall almost always carries load from the floor and roof above, so a structural engineer sizes the RSJ, we install temporary props, then remove the masonry in stages before lowering the new beam onto padstones at each bearing.
Where the wall being removed is a party wall shared with the neighbouring terrace, which is often the case in Tooting's tightly packed streets, the Party Wall Act applies and you serve the correct notices before work begins. Every beam is checked and signed off by Wandsworth building control, so the structure is documented and compliant. We keep the house propped and stable throughout, and make good the ceilings and walls afterwards.
When Tooting homeowners extend to the rear or infill the side return, the original back wall of the house comes out and a steel beam takes the load in its place. The engineer sizes the steelwork with your engineer to suit the new open-plan span, then build in padstones or spreader plates so the load transfers cleanly into the existing brickwork. Larger openings sometimes need a goalpost frame with steel posts rather than a single beam.
Because SW17 terraces sit wall to wall with their neighbours, the beam bearings frequently land in the shared party wall, which means a party wall award before we cut in. We coordinate the propping, the demolition and the beam lift so the house is never left unsupported, and building control inspects the steel before it is cased in. The result is a wide, uninterrupted opening between your kitchen and garden with no visible structure.
Tooting homeowners choose GS Renovation because we have removed load-bearing walls in SW17 terraces for over 30 years and treat the structure as the priority. We work to your engineer's design, prop safely, serve any book Wandsworth building control at every stage, so the beam is right, signed off and hidden in a clean finish.

FAQ
The honest answer is that the risk sits in what is concealed. GS Renovation lists what the SW17 survey could not inspect, so a Tooting homeowner knows where the RSJ and steel beam installation figure might move before signing anything. The Wandsworth Council fee and the engineer's fee are already included rather than sprung later. Nothing is added to the Wandsworth account without your written agreement. Ring 07472 424 226 if you want the SW17 risks explained before quoting. 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.
You get a written one, and you can hold us to it. The RSJ and steel beam installation programme for your SW17 home marks the propping, the structural stage, the Wandsworth Council inspection points and the making good. GS Renovation coordinates the trades in-house so a Tooting project does not stall in the gaps. Ask on 07472 424 226 how it usually runs in Wandsworth. Email info@gsrenovationltd.co.uk and we will send the Tooting programme together with the written quotation.
We do what we say, and we put it in writing first. A Tooting homeowner gets an itemised RSJ and steel beam installation quotation, a programme for the SW17 property and weekly updates, which removes the guesswork that makes building work stressful. GS Renovation appoints the structural engineer where the design needs one and builds to their specification. Free quotes, no obligation, right across Wandsworth. Email info@gsrenovationltd.co.uk to arrange an SW17 visit. Insurance documents follow on request across Wandsworth.
Yes, on any load-bearing opening. The floor and walls above are carried on adjustable props while the masonry comes out and the steel goes in. Getting the propping right at your SW17 property is the part that protects the rest of the Tooting house.
We do, week in and week out. Solid-wall Victorian terraces with original chimney breasts and suspended timber floors make up much of Tooting, so RSJ and steel beam installation on them is core work for GS Renovation rather than an occasional job. The SW17 survey establishes what is actually there before anything structural is touched. Wandsworth Council building control is coordinated by us in the usual way. Ask on 07472 424 226 what an SW17 property of that age typically needs before RSJ and steel beam installation can even begin in Tooting.
Usually yes. In Tooting's SW17 terraces the beam often bears onto the party wall shared with your neighbour, so the Party Wall Act applies and notice must be served before work starts. We help you appoint a surveyor and serve the correct notices, and we still need a structural engineer's design and Wandsworth building control sign-off for the beam itself.
Regularly, because a great deal of our RSJ and steel beam installation work is here. Being close enough to an SW17 property to attend quickly is what makes the programme and the aftercare work in practice. GS Renovation charges nothing for the Tooting survey and nothing for reaching you. Call 07472 424 226 for the next available slot in Wandsworth.
