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 we help 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. We size 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 party wall notices and book Wandsworth building control at every stage, so the beam is right, signed off and hidden in a clean finish.
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
Every Tooting project is priced on its own merits, as the cost of RSJ and steel beam installation varies with the size, specification and condition of the home. We give a clear, itemised quote up front with no obligation. Call 07472 424 226 for an estimate tailored to your property. 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.
Most RSJ and steel beam installation projects in Tooting take between two and eight weeks depending on the scope and whether structural work is involved. We provide a clear programme before work begins so you know exactly what to expect.

Removing a load-bearing wall in Tooting 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 Tooting'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. 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.
We cover the whole of Tooting and the SW17 area and the surrounding South West London. If you are nearby and not sure, just call 07472 424 226 and we will tell you straight away.
