Steel beam installation, rsj and structural alterations in Chislehurst. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Chislehurst, from the bay-fronted Victorian and Edwardian terraces near Chislehurst Common to the substantial homes throughout BR7. With over 30 years of structural experience across Bromley, we remove load-bearing walls safely, working to a structural engineer's calculations and Bromley Council building control sign-off.

In a typical Chislehurst terrace the wall between the front reception and the rear room is load-bearing, and often forms part of a shared party wall with the neighbouring house. Before any demolition, we have a structural engineer calculate the correct beam size, then install temporary propping to carry the floors and roof above. Only once the load is safely supported do we cut out the old masonry in careful, staged sections.
The new steel beam bears onto padstones spread across the remaining brickwork, so the load is transferred down through sound masonry rather than concentrated on a weak point. Where the wall is shared with your neighbour under the Party Wall Act, we help you serve the correct notices before work begins. Bromley Council building control inspects the beam and its bearings, and the job is signed off with a completion certificate you can keep for any future sale.
Many Chislehurst period homes still have chimney breasts in the front and rear rooms, and homeowners often want the breast removed to reclaim floor space. Because the stack and dividing chimney frequently sit within the shared party wall, this is structural work that needs proper support. We install a gallows bracket or a steel beam to carry the masonry left above, calculated by an engineer rather than guessed on site.
Removing a breast that is shared with the house next door brings the Party Wall Act into play, so notice to your neighbour is part of the process. We prop the retained stack, take down the brickwork in stages, and fit the support before making good the walls, floor and ceiling. Building control checks the work, and we leave the room ready for replastering so your renovation can carry straight on without delay.
Chislehurst homeowners choose GS Renovation because steel work in a period terrace is unforgiving, and we treat it that way. Every beam is sized by a structural engineer, propped correctly and signed off by Bromley Council building control. With 30+ years across BR7 and the wider borough, we handle party wall notices, staged demolition and making good as one accountable 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!

Removing a load-bearing wall in Chislehurst 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 Chislehurst'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.
Usually yes. In most Chislehurst terraces the wall you are opening up or the chimney stack you are removing sits within the party wall shared with your neighbour, so the Party Wall Act applies. We help you serve the correct notice before work starts. The beam itself is a building regulations matter, sized by a structural engineer and signed off by Bromley Council building control.
