Steel beam installation, rsj and structural alterations in Hayes. Trusted, professional, 30+ years' hands-on experience.
GS Renovation has spent over 30 years opening up homes across Hayes, where 1930s semi-detached and interwar houses on generous UB3 plots dominate the streets. When you want to remove a load-bearing wall or create an open-plan ground floor, our team installs steel beams and RSJs that carry the load safely and pass building control.

Most 1930s semis in Hayes were built with the front reception, rear reception and a narrow kitchen kept apart by internal load-bearing walls. Taking one of those walls out calls for a steel beam sized by a structural engineer to suit the span and the loads above, including the floor and any masonry. We bear each end onto a concrete padstone, set temporary props to hold the structure, then remove the wall in a safe, staged sequence.
Because these interwar houses on generous UB3 plots often share a party wall or a chimney stack with the neighbouring semi, work near that dividing wall usually triggers the Party Wall Act. We serve the correct notices before we start, keep the neighbours informed, and record the condition of both properties. Every beam installation is registered with Hillingdon Council building control and signed off once the steelwork, padstones and fire protection have been inspected.
The classic Hayes knock-through joins the two ground-floor receptions or opens the kitchen into the dining room to make a single sociable space. Before any wall comes down we confirm what it carries, because in a 1930s semi a ground-floor wall frequently supports the first-floor joists and sometimes a chimney breast above. Our structural engineer calculates the beam, and we plan the propping so the upper floors stay fully supported throughout the demolition.
On the generous plots common in UB3 we also handle larger openings, such as removing most of a rear wall for bifold doors or forming a wide opening between an extension and the original house. Where two beams meet or a beam lands on an existing wall, we build proper padstones and check the bearing. You get one team managing the engineer, the steel, the building control inspections and the making good afterwards.
Hayes homeowners choose GS Renovation because we treat structural work as the serious job it is. With 30+ years behind us, we coordinate the structural engineer, the temporary propping, the Party Wall Act notices and Hillingdon Council building control, then leave the opening plastered and ready. One accountable team, honest pricing and a beam installation done safely in an occupied home.
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
The cost of RSJ and steel beam installation in Hayes depends on the size of the property, the specification and the scope of work. GS Renovation provides free, detailed and itemised quotations for every Hayes project. Call 07472 424 226 or email info@gsrenovationltd.co.uk for a no-obligation 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 Hayes 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 Hayes'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 1930s semis in Hayes share a party wall with the house next door, and cutting into it to seat a steel beam is notifiable work under the Party Wall Act. We serve the notice on your neighbour before starting, agree the condition of both homes, and keep the whole process documented alongside the building control sign-off.
We do. GS Renovation covers all of Hayes and the UB3 area and the wider West London. Call 07472 424 226 and we will confirm we work on your road.
