Steel beam installation, RSJ and structural alterations in Haringey. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Haringey, from the bay-fronted terraces of Crouch End and Muswell Hill to the period homes of Tottenham and Wood Green. With over 30 years of structural work in N4, N8, N10, N15, N17 and N22, we remove load-bearing walls safely and sign every project off with building control.

The Victorian and Edwardian terraces that fill N8 and N10 were built with solid brick dividing walls, and the wall between the two front and rear reception rooms is almost always load-bearing. Opening it up needs a steel beam sized by a structural engineer, bearing onto padstones at each end, with temporary propping in place before any brickwork comes down. We work in careful, staged demolition so the floors above stay supported throughout.
Our team calculates the loads, orders the correct steel and arranges the padstones before a single course is touched. In the closet-wing kitchens common to Haringey homes, we often combine beam work with removing the wall into the rear addition, always keeping the structure fully propped until the RSJ is seated, packed and taking the load it was designed for.
In a terraced street the dividing wall to next door is a shared party wall, and the chimney stacks frequently straddle it too. When a beam bears into that wall, the Party Wall etc. Act 1996 applies, so notice must be served on the adjoining owner before work starts. We help Haringey homeowners understand who needs notifying and how the process runs, whether the neighbour consents or a party wall surveyor becomes involved.
Getting this right protects you legally and keeps relations with the neighbour civil, which matters on the tightly packed streets around Finsbury Park and Tottenham. Alongside the party wall side, we submit the job to Haringey building control under the Building Regulations, arrange the inspections and hand over the completion certificate you will want when you eventually sell the house.
The first hour of opening up tells you what a house has been through. In Haringey terraces we regularly find a timber bressummer over an old opening that somebody bricked up, joists notched almost through for a bathroom waste, an earlier steel sitting on no padstones at all, or a brick arch carrying the wall above that nobody knew was there. Terraces in this borough have been altered by three or four generations of owners.
None of these stop the job, but they change the design, so the engineer sees them before we go any further. A previously altered wall may have less sound bearing available than the drawing assumed, and a notched joist near a new beam end needs strengthening before it is loaded. This is why we allow for opening up as a stage in its own right rather than pricing on a hopeful assumption. It also means the inspector sees what is actually there rather than what was drawn.
Haringey homeowners choose GS Renovation because we treat steel beam work as the structural job it is, not a quick knock-through. We coordinate the engineer's calculations, the padstones, the propping and the building control sign-off, and we advise on party wall notices for shared walls. Thirty years across North London means the beam is sized right and installed safely.

FAQ
It compares well, mainly because there is no head office to fund. GS Renovation is the contractor doing the RSJ and steel beam installation work at your N4 property, not a broker passing a Haringey job on with a margin added. You deal with the people on site, and the quotation shows the Haringey Council element rather than an administration fee. Compare the scope, not just the total. Ring 07472 424 226 and GS Renovation will go through the N4 lines with you. 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.
Allow time for the quotation, the approvals and then the build itself. After the free survey at N4, GS Renovation issues the RSJ and steel beam installation quotation quickly, and the Haringey Council route decides how much sits between agreement and starting on your Haringey home. The construction phase is programmed week by week. Ring 07472 424 226 and we will map it against a Victorian and Edwardian terraced property. Nothing about a Haringey start date is committed before the N4 scope is agreed.
Because you get one accountable team rather than a chain of subcontractors. GS Renovation is the contractor carrying out RSJ and steel beam installation at your N4 property, with a named project manager from survey to handover and full insurance throughout. We are rated 4.9 from 31 reviews on MyBuilder, and the Haringey Council paperwork is handled for you. That applies across Haringey and the wider Haringey. Ring 07472 424 226 and ask for N4 references. Insurance details follow on info@gsrenovationltd.co.uk request.
If the beam bears into a wall shared with a neighbouring property, yes, and that covers most terraces and semis in Haringey. Notice must be served before work begins, and the duty sits with you as building owner. We prepare the notices for your N4 address.
Yes, though the standard it is built to is identical. RSJ and steel beam installation at an N4 property of that age is sequenced to protect the existing fabric, uses details suited to the original construction, and is confirmed by an engineer before design. GS Renovation sets that out before starting. Haringey Council inspects exactly as it would on a modern Haringey house. Ask on 07472 424 226 how RSJ and steel beam installation differs at an N4 address of that particular age.
Usually yes. In a Crouch End terrace the beam typically bears into the shared party wall with next door, which brings the Party Wall etc. Act 1996 into play, so you must serve notice on the adjoining owner before work begins. We guide you through it and separately arrange building control sign-off under the Building Regulations for the structural work itself.
We work on both, and the difference is consent rather than construction. A Haringey flat needs the freeholder's agreement before RSJ and steel beam installation begins, and in a period block the structure at N4 may be carrying load from several storeys. GS Renovation establishes that with an engineer first. The survey across Haringey costs nothing. Ring 07472 424 226 and we will explain the Haringey Council position. Freeholder consent is confirmed before any N4 design work begins.
