Steel beam installation, rsj and structural alterations in Edgware. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Edgware and the wider HA8 postcode, from the 1930s semi-detached homes near Mill Hill to the interwar houses toward Hendon and Golders Green. With more than 30 years of structural experience, we remove load-bearing walls safely and open up these solid suburban homes.

The typical Edgware project takes a 1930s semi-detached house and removes the wall between the front reception and the rear room, or the wall dividing the kitchen from the dining space. These interwar walls are usually load-bearing, carrying the floor above and sometimes a chimney stack, so a structural engineer calculates the correct RSJ size before any work begins. We never guess a section from experience alone.
Every beam bears onto padstones spread across the existing brickwork, so the concentrated load transfers safely into the walls below. We install temporary propping first, take the wall down in careful staged sections rather than all at once, then lift the steel into place and build the padstones and any new supporting piers. Building control inspects and signs off the finished structural work.
Because Edgware is dominated by semi-detached and interwar terraced stock, the wall between you and your neighbour is frequently a shared party wall, and the chimney breast often sits within it. Where a steel beam bears on or cuts into that shared wall, the Party Wall etc. Act applies and formal notice must be served on the adjoining owner before work starts. We flag this early so nothing stalls midway.
We help you understand when notice is needed, what the neighbour can agree to, and how the timescales fit your build programme. For a straightforward knock-through away from the boundary, party wall matters may not arise at all. We coordinate the engineer, the notices and the building control application so your Edgware project moves forward without avoidable delays or disputes.
Edgware homeowners choose GS Renovation because we treat structural work as the serious job it is. The engineer sizes the steel, we prop and demolish in safe stages, the beam bears on proper padstones, and building control signs it off. With 30+ years across HA8 and Barnet, we know how these interwar semis are built and how to open them up safely.
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
Pricing RSJ and steel beam installation in Edgware comes down to the size of the job, the specification you choose and the condition of the property. Rather than guess, we survey and give you a fixed, itemised quote you can rely on. Call 07472 424 226. 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 Edgware 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.
GS Renovation knows Edgware's homes and how to renovate them properly. We handle the structure, the services and the finishes, deal with building control for you, and leave you with work that is certified, guaranteed and built to last.
Removing a load-bearing wall in Edgware 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 Edgware'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.
Removing an internal load-bearing wall in your HA8 home needs building regulations approval, not planning permission. A structural engineer sizes the RSJ, we install it on padstones, and building control inspects and signs it off. Planning permission only comes into play for extensions or exterior changes. Where the wall is shared with your neighbour, a party wall notice may also be required.
We cover the whole of Edgware and the HA8 area and the surrounding North London. If you are nearby and not sure, just call 07472 424 226 and we will tell you straight away.
