Steel beam installation, rsj and structural alterations in Wembley. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Wembley, working mainly with the 1930s semi-detached and interwar suburban houses that fill HA9. With over 30 years of structural experience in Brent, we remove load-bearing walls safely, from ground-floor knock-throughs to chimney breast removals, so these solidly built homes gain the open space that modern family life needs.

The interwar semis around Wembley were built with an internal load-bearing spine wall dividing the front reception from the rear, and homeowners in HA9 regularly ask us to take it out for one continuous living space. Every beam is sized by a structural engineer, not guessed at, and bears onto concrete padstones spread across the surviving brickwork. We install temporary props first, then remove the wall in controlled stages so the floors above stay fully supported.
Because many of these 1930s houses sit as semi-detached pairs, the spine wall or a chimney stack often falls within a shared party wall with the neighbour. Where that applies we serve the correct Party Wall Act notices before any cutting begins. Building control inspects the padstone bearings and the finished steelwork, and we book those inspections so your project is signed off properly rather than left in limbo.
A common Wembley job is widening the kitchen at the back of an interwar semi, dropping a beam over the old rear wall to link the kitchen with a dining area or a future extension. On the generous plots typical of this suburb, we also see beams supporting a loft conversion or holding up first-floor masonry once a downstairs opening is formed. We calculate the loads, order the right steel section and manage delivery down the sometimes narrow side access these houses have.
Safe demolition is the part homeowners underestimate. We sheet and protect the property, prop from solid bearings, and cut back the masonry gradually rather than dropping a wall in one go. Once the RSJ is seated, packed and bolted where needed, we make good the surrounding plaster and reinstate ceilings. Throughout the work in HA9 we keep Brent Council building control informed so the completion certificate follows without delay.
Wembley homeowners choose GS Renovation because steelwork in these interwar semis demands respect for shared party walls, original masonry and building control. With 30+ years across Brent, we handle the engineer's calculations, the propping, the safe demolition and the sign-off as one accountable job, so your load-bearing wall comes out cleanly and the house stays sound.
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
There is no fixed price for RSJ and steel beam installation in Wembley, because so much depends on your property and what you want to achieve. We survey first, then provide a transparent written quotation. Contact GS Renovation on 07472 424 226 for a free estimate. 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.

Removing a load-bearing wall in Wembley 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 Wembley's homes are 1930s and interwar properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.
Very likely, yes. Most interwar semis in HA9 share a party wall with the neighbouring house, and the spine wall or chimney breast you want opened up often sits within it. Under the Party Wall Act you must serve notice before work starts. We identify whether your beam affects the shared wall and prepare the correct notices as part of the project.
Yes. We work throughout Wembley and the HA9 area, as well as the surrounding parts of North West London. Contact us on 07472 424 226 to confirm we cover your street.
