Steel beam installation, RSJ and structural alterations in Willesden. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Willesden, working daily with the bay-fronted Victorian and Edwardian terraces that fill NW10. With more than 30 years behind us in Brent, we remove load-bearing walls safely, prop the structure while we work, and hand the finished job to building control for sign-off.

The wall between the front and middle reception in a Willesden terrace almost always carries load, and so does the wall closing off the rear closet wing. Before anything comes down we have a structural engineer size the beam for the exact span and loading, then we set steel props and needle supports so the floors above stay held while the old wall is taken out in careful, staged sections.
Once the opening is formed we lift the RSJ into place and seat each end onto a concrete padstone that spreads the load safely into the remaining brickwork. In these solid-wall NW10 houses the masonry above is often carrying a chimney breast or a first floor bedroom, so nothing is left to chance and every stage is checked before we move on.
Willesden terraces are joined to their neighbours, and the dividing wall, along with the chimney stacks built into it, is usually a shared party wall. When a beam bears onto that wall or we cut a pocket into it for a padstone, the Party Wall Act applies and your neighbour must be served formal notice before work begins. We flag this early so the notice period does not hold up your programme.
We guide you through serving notices to the adjoining owners, whether the neighbouring house is another terrace or a converted flat, which is common across NW10. Getting the paperwork right protects you legally and keeps relations on the street civil. Alongside the party wall side we coordinate the engineer's calculations and the building control application so the steelwork is inspected and certified from start to finish.
The hole in the wall and the opening you end up living with are two different measurements, and it is worth knowing that before you picture the finished room. The structural opening is set by the engineer's beam and its bearings. What you see afterwards is that opening less the fire protection board on the underside of the steel, less the plaster, and less any return or reveal formed at the ends.
On a typical NW10 terrace that can be a difference of a hundred millimetres or more in height, and a similar amount at each side. It matters if you are planning a door, a wide fridge or a run of tall units to sit within the opening. We set the finished dimensions out with you before the steel is ordered, so the beam is sized around what you actually want rather than the other way round, which is a conversation better had on paper than after the steel is in.
Willesden homeowners choose GS Renovation because we treat steel beam work as a structural discipline, not a quick knock-through. One team handles the engineer's design, the propping, the padstones for shared NW10 walls and the building control sign-off, with 30+ years of experience across Brent behind every job.

FAQ
We would rather not, because a phone figure is a figure that changes. What RSJ and steel beam installation costs at an NW10 address depends on structure and condition we can only see on site, particularly in Victorian and Edwardian terraced housing. GS Renovation will happily talk through the likely scope on 07472 424 226, then survey the Willesden property free of charge. The written quotation follows that visit. Nothing is owed for the NW10 visit, in Brent or anywhere beyond it. 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.
We start when we can see the job through. Taking on RSJ and steel beam installation at a Willesden property and then disappearing to another site is the commonest complaint about builders, so GS Renovation schedules the NW10 project properly instead. Availability changes by season and by how many Brent jobs are running. Call 07472 424 226 and you will get honest dates, not a holding answer. The NW10 survey is free and puts a Willesden project into the Brent schedule.
Yes. We are rated 4.9 from 31 reviews on MyBuilder, all public and written by the homeowners themselves. The work behind them is the same RSJ and steel beam installation we would carry out at your NW10 address, on similar Edwardian bay-fronted houses with generous ceiling heights and long rear gardens across Brent. GS Renovation will also give you addresses of finished Willesden projects. Seeing one in person is worth more than reading about it. Ring 07472 424 226 to arrange that. The Brent rating covers work of exactly this kind.
Almost any wall can be opened up, but what the beam has to carry and what it bears onto change completely. In a Willesden property the load path matters more than the wall itself, which is why an engineer assesses the NW10 address before we quote.
Original features are an asset, and we treat them that way. Before RSJ and steel beam installation starts at a Willesden address, GS Renovation agrees what is being kept, protects it physically, and plans the NW10 sequence accordingly. Making good afterwards matches the existing profiles. That care is part of the quotation, not an extra billed later in Brent. Ask on 07472 424 226 how RSJ and steel beam installation is planned around the original detail at an NW10 property instead.
Removing an internal load-bearing wall needs building regulations approval, not planning permission. A structural engineer sizes the RSJ, we install it on padstones with temporary propping, and building control inspects and signs it off. If the wall is shared with a neighbour, which is normal in NW10 terraces, the Party Wall Act also applies and notices must be served first.
There is none, and it is worth asking even if the job feels too small. RSJ and steel beam installation enquiries across Willesden range from a single opening to a whole-house programme, and GS Renovation quotes both on the same basis. The NW10 visit costs nothing and carries no obligation. Email info@gsrenovationltd.co.uk with a description and some photographs. Building control still goes through Brent Council where the work requires it. Small RSJ and steel beam installation work at NW10 is quoted the same way.
