Steel beam installation, rsj and structural alterations in Hornchurch. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Hornchurch, from the 1930s semi-detached houses off the RM11 avenues to the interwar detached homes near Raphael Park. With more than 30 years working on Havering's suburban stock, we open up load-bearing walls safely, size every beam properly and see the work through to building control sign-off.

The typical Hornchurch project removes the wall between the front and rear reception of a 1930s semi, or the wall into the original kitchen, to create one open living space. These interwar houses were built with solid brick and cavity construction, so the dividing wall usually carries the floor and roof loads above. We start with a structural engineer's calculation, which sizes the RSJ and specifies the padstones it bears onto at each end.
Before any brick comes down we install temporary propping to hold the structure, then carry out staged demolition so nothing is left unsupported. The steel is lifted into position, seated on concrete or engineering-brick padstones and packed tight, and the load is transferred slowly. Every stage is booked in with Havering building control so the beam, bearings and fire protection are inspected and signed off.
Many Hornchurch semis share a party wall with the neighbouring house, and the chimney breasts and dividing structure often sit within it. Where a beam bears into or cuts into that shared wall, the Party Wall Act applies and your neighbour must be served the correct notice before work begins. We flag this early so the notice period does not hold up your start date, and we keep the paperwork straightforward.
On detached interwar houses on the generous plots common around Hornchurch Country Park, party wall matters may not arise, but the engineering is no less careful. We coordinate the propping, the padstone bearings and the building control inspections whether the job is a modest through-lounge or a wider knock-through supporting a first floor and roof. You get one team accountable for the structure from calculation to plaster.
Hornchurch homeowners choose GS Renovation because we treat steelwork as structural engineering, not guesswork. Every RSJ is sized by an engineer, propped correctly, seated on proper padstones and signed off by Havering building control. With over 30 years across RM11 and the wider borough, we handle party wall notices, tidy working and a finish ready for your next phase.
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
We price each Hornchurch project individually, because the cost of RSJ and steel beam installation depends on far more than floor area. After a free survey you receive a clear written breakdown with no hidden extras. Call 07472 424 226 or email info@gsrenovationltd.co.uk. 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 Hornchurch 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 Hornchurch 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 Hornchurch'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.
Often yes. In a 1930s Hornchurch semi the dividing wall to your neighbour is usually a shared party wall, so if the steel beam bears into it or you cut into the chimney breast within it, the Party Wall Act applies and your neighbour must be served notice. We identify this at the survey stage and manage the process so it does not delay the build.
Yes, Hornchurch is one of our core areas. We work on every street and the RM11 area and across the wider East London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
