Steel beam installation, rsj and structural alterations in Bexleyheath. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Bexleyheath, working daily on the 1930s semi-detached and interwar houses that line the DA6 streets near Danson Park. With over 30 years of structural experience, we remove load-bearing walls safely, open up dated interwar layouts and keep every job signed off by building control.

The typical Bexleyheath project takes a 1930s semi and opens the wall between the two ground-floor reception rooms, or removes the wall into the rear kitchen. These interwar dividing walls almost always carry the floor above and part of the roof load, so a structural engineer sizes the RSJ, we form padstones to spread the bearing, and building control inspect the steel before it is cased in.
Before anything comes down we install temporary propping and demolish in careful stages, protecting the rest of the house. On the generous plots common in DA6, this creates the bright, connected ground floor that suits family life while keeping the solid interwar structure sound above.
Many Bexleyheath semis share a party wall with the house next door, and chimney breasts and dividing walls frequently sit within that shared structure. Where our steelwork bears into or cuts into a party wall, the Party Wall Act applies, so we help you serve the correct notices on your neighbour before work starts and keep the paperwork straight.
We coordinate the structural engineer's drawings, the Bexley Council building control application and the propping schedule so the beam goes in on a clear, agreed sequence. Getting the party wall matters settled early avoids disputes and keeps your Bexleyheath project moving without last-minute delays or objections.
Bexleyheath homeowners choose GS Renovation because we treat structural work as the specialism it is. One accountable team handles the engineer's calculations, the propping, the padstones, the Party Wall Act notices and building control sign-off, with 30+ years of experience behind every beam we set into a DA6 interwar 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

Removing a load-bearing wall in Bexleyheath 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 Bexleyheath'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. Most Bexleyheath semis share a party wall with next door, and if your new steel bears into or cuts into that shared wall the Party Wall Act applies. We advise on serving notice on your neighbour, work with your structural engineer on the beam design, and arrange building control inspection so the job is fully compliant.
