Steel beam installation, rsj and structural alterations in Wimbledon. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Wimbledon, working daily with the bay-fronted Victorian and Edwardian terraces that fill SW19 around Wimbledon Common and the All England Club. With over 30 years of structural experience in Merton, we remove load-bearing walls safely and give you a bright, open ground floor that still stands solid.

The dividing wall between the front reception and the middle room in a Wimbledon terrace is almost always load-bearing, carrying floor joists and the weight above. We never touch it on assumptions. A structural engineer calculates the load and specifies the correct RSJ, and we cast or bed padstones so each end of the beam bears properly onto solid masonry rather than crushing old brickwork.
Before any brick comes down, we install temporary propping to hold the floors and any chimney breast above, then work through a staged, controlled demolition. On the solid-wall construction typical of these SW19 homes, tidy sequencing matters, so we cut back cleanly, seat the steel, pack the bearings and only strike the props once everything is fully supported and dry.
Many Wimbledon terraces share a party wall with next door, and chimney stacks and dividing walls frequently sit right on that line. When a steel beam bears into a shared wall, or you cut pockets for padstones within it, the Party Wall etc. Act 1996 applies. We flag this early so you can serve the correct notice on your neighbour before work begins and avoid disputes later.
We coordinate the structural drawings, the engineer's calculations and the notices so nothing stalls on site. Building control must inspect and sign off the beam installation, checking the bearings, fire protection to the steel and the finished padstones. We book the inspections, meet the surveyor and hand you the completion certificate, which matters when you eventually sell a home in Merton.
Wimbledon homeowners choose GS Renovation because we treat structural work as structural work. Engineer-sized steel, proper padstones, temporary propping and staged demolition, plus honest handling of party wall notices and building control sign-off. Over 30 years across SW19 means we know how these Victorian and Edwardian terraces are built and how to open them up without cutting corners.
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
Every Wimbledon project is priced on its own merits, as the cost of RSJ and steel beam installation varies with the size, specification and condition of the home. We give a clear, itemised quote up front with no obligation. Call 07472 424 226 for an estimate tailored to your property. 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.
A straightforward Wimbledon project can be done in a couple of weeks, while a larger RSJ and steel beam installation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.
GS Renovation's team brings over 30 years of hands-on experience to RSJ and steel beam installation and wider building work across Wimbledon and the surrounding area. We offer free quotes, a dedicated project manager, full insurance, building control compliance where required, and comprehensive aftercare.
Removing a load-bearing wall in Wimbledon 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 Wimbledon'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 Wimbledon terraces the wall you are altering, or the wall the new beam bears into, is a shared party wall with your neighbour. Cutting bearing pockets or padstone recesses into it brings the Party Wall Act into play, so you must serve notice first. We identify this at the survey stage and guide you through the process before any steel goes in.
We do. GS Renovation covers all of Wimbledon and the SW19 area and the wider South West London. Call 07472 424 226 and we will confirm we work on your road.
