Steel beam installation, rsj and structural alterations in Chiswick. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Chiswick, from the bay-fronted Victorian terraces near Chiswick House to the Edwardian homes towards Brentford. With over 30 years of structural work in W4, we remove load-bearing walls safely, propping, beaming and signing off through Hounslow Council building control on every job.

The dividing wall between the front and rear reception in a Chiswick terrace is almost always load-bearing, carrying floor joists and often a chimney breast above. We start with a structural engineer sizing the RSJ for the exact span and load, then install padstones to spread the bearing into the solid brickwork. Temporary props hold the structure while we cut out the wall in careful stages, so nothing above ever moves.
Because W4 stock is largely bay-fronted Victorian and Edwardian terracing, spans are predictable but the masonry is old and needs respect. We work clean in occupied homes, sheet everything and keep dust down. Once the beam is seated and levelled, we pack, fireproof and encase it, then arrange the building control inspection so your knock-through is fully certified from the outset.
Chiswick terraces sit in continuous rows, so the wall between you and your neighbour is a party wall and the chimney stacks frequently straddle it. When a beam bears into that shared wall, or when you cut pockets for padstones near it, the Party Wall Act applies. We flag this early so you can serve the correct notices on adjoining owners before any structural cutting begins, which keeps the project lawful and neighbourly.
We coordinate with your party wall surveyor, provide the engineer's calculations and method statement, and schedule the noisy breaking-out work to minimise disruption along the terrace. On mid-terrace W4 homes this matters on both sides, so we plan bearings and propping to avoid overloading a neighbour's masonry. Getting the notices and the structural detail right together is what stops a knock-through turning into a dispute.
Chiswick homeowners choose GS Renovation because we handle the whole steel job under one roof, engineer's calculations, propping, padstones, safe demolition and building control sign-off, with the party wall side flagged early. Thirty years of beams across W4 terraces means we know how this stock behaves and we leave it structurally sound and certified.
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
Pricing RSJ and steel beam installation in Chiswick comes down to the size of the job, the specification you choose and the condition of the property. Rather than guess, we survey and give you a fixed, itemised quote you can rely on. Call 07472 424 226. 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 Chiswick 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 Chiswick 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 Chiswick'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.
Yes. Removing a load-bearing wall and fitting a steel beam is structural work that falls under building regulations, so it needs Hounslow Council building control sign-off, not planning permission. We supply the structural engineer's calculations, install to those figures with proper padstones, and arrange the inspections so your beam is certified. Where the beam affects a shared party wall, notices are also required.
Yes, Chiswick is one of our core areas. We work on every street and the W4 area and across the wider West London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
