Professional RSJ steel beam installation and structural alterations across Central and Greater London. GS Renovation — trusted, professional, 30+ years experience.
RSJ (Rolled Steel Joist) installation is one of the most common structural alterations carried out in London properties. Whether you are removing a load-bearing wall to create an open-plan kitchen-diner, converting a loft, or underpinning a basement, steel beams are the backbone of safe, compliant structural work. GS Renovation has been installing RSJs across London for over 30 years, building a reputation for precision engineering, professional project management, and impeccable finishing.
Every RSJ installation we carry out begins with a detailed structural survey and engineer's calculations. We work with chartered structural engineers who design the steel beam specification — including size, grade, and bearing details — to ensure the altered structure is safe and compliant with Building Regulations. Our team then procures, delivers, and installs the steelwork with minimal disruption to your home, before making good with plastering, decoration, and any associated building work.
London's diverse housing stock presents a wide range of structural challenges. Victorian terraces with lime mortar walls require different techniques to inter-war cavity construction or post-war concrete-framed buildings. Our structural team has deep experience across all London property types, ensuring every RSJ installation is carried out safely, efficiently, and to the highest standard.
Our steel beam installation service covers every step of the process, from initial structural survey through to building control sign-off. We handle beam design, procurement, temporary propping, installation, and all associated building work including needle holes, padstones, and fire protection. Every installation is completed with full documentation for your records and future property transactions.
Removing a load-bearing wall is one of the most transformative alterations you can make to a London property. It opens up cramped, separate rooms into flowing, light-filled living spaces. Our team assesses the wall's structural role, designs the appropriate steel support, installs the beam, and removes the wall — all while maintaining the stability of the building above. We handle party wall agreements where the wall is shared with a neighbouring property.
All structural alterations in London require building control approval. We manage the entire compliance process on your behalf, submitting building notice applications, scheduling inspections at each stage, and obtaining the completion certificate that confirms your work meets Building Regulations. This documentation is essential for future property sales and remortgaging.
