Steel beam installation, rsj and structural alterations in Hounslow. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Hounslow, from the bay-fronted Victorian terraces of Isleworth to the Edwardian villas near Chiswick House. With more than 30 years of experience across TW3, TW4, TW5, TW7, TW8 and W4, we remove load-bearing walls safely and leave the structure signed off and sound.

The typical Hounslow project opens up the ground floor of a Victorian or Edwardian terrace, taking out the wall between the front and middle reception rooms or the wall into a rear closet wing. These are usually load-bearing, carrying floor joists and the chimney breast above, so a structural engineer sizes the steel beam to suit the span and the load coming down from the storeys overhead.
We set up temporary propping first, then carry out staged demolition so nothing is left unsupported. The RSJ bears onto padstones at each end, spreading the load into the solid brickwork the borough's terraces are built from. Every beam we fit around Isleworth, Brentford and Chiswick is installed to the engineer's specification and inspected by building control before we plaster it in.
In Hounslow's terraced streets the dividing wall between you and your neighbour is a shared party wall, and the chimney stacks often sit within it. When a beam bears into that wall, or when we cut a padstone pocket into it, the Party Wall Act applies. We help you serve the correct notices on adjoining owners in good time so the work stays legal and neighbourly, whether you are in TW7 or over towards W4.
Getting the sequence right matters most when the steel takes weight from a chimney breast or an upper floor. We work closely with your structural engineer, arrange the propping, and time the padstone bearings so the load transfers cleanly onto the new beam. Building control checks the padstones, the bearings and the beam before sign-off, giving you documented proof the structure is safe for years to come.
Homeowners across Hounslow trust GS Renovation because we treat steelwork as the serious structural job it is. We coordinate the engineer, the propping, the padstones and building control, handle party wall notices on shared walls, and work tidily in your occupied home. Thirty years of beam installations across the borough's terraces stand behind every job.
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 Hounslow, 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 Hounslow 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 Hounslow'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.
You need building regulations approval, not planning permission, for an internal steel beam. It is structural work, so building control inspects the engineer's design, the padstones and the bearings before sign-off. Planning permission only comes into play for extensions or external changes. If the wall is a shared party wall, you will also need to serve a party wall notice on your neighbour.
Absolutely. Our team works right across Hounslow and the TW3 area and neighbouring parts of West London. Get in touch on 07472 424 226 to check coverage for your address.
