Steel beam installation, RSJ and structural alterations in Havering. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and structural steel across Havering, from the 1930s semis of Hornchurch to the interwar streets around Romford. With more than 30 years of experience working RM1 through RM14 homes, we open up load-bearing walls safely, with beams sized by a structural engineer and every stage signed off by building control.

The interwar semi-detached houses that fill Havering typically have a solid dividing wall between the front and rear reception rooms, and often a load-bearing wall between the kitchen and the back of the house. Removing either to create a single open space means transferring that load onto a steel beam. Our structural engineer calculates the size, and the beam bears onto concrete padstones at each end so the load passes safely down through the existing brickwork.
Before any brick comes out, we install temporary props to carry the floors and roof above, then remove the wall in staged, controlled sections. Once the RSJ is seated and the padstones have cured, we ease the load onto the steel and strike the props. Building control inspects the work at key stages, and where a wall is shared with the neighbouring semi, you serve the correct Party Wall Act notices before we begin.
Because Havering is dominated by semi-detached and terraced interwar stock, the wall you want to remove is frequently the one you share with next door. The chimney breast and the dividing wall between two semis usually sit on a party wall, which brings the Party Wall Act into play. you serve notice on the adjoining owner in good time, and coordinate the schedule of condition so both households are protected before the steel goes in.
Chimney breast removal is another common request in these homes, where a redundant stack eats into a bedroom or reception room. Taking it out means supporting the masonry above with a gallows bracket or a beam, again designed by an engineer and inspected by building control. Whether you are in RM11 Hornchurch or an RM2 street near Raphael Park, we handle the structural calculations and the physical work as one managed job.
If the beam bears into a shared wall, the Party Wall etc. Act applies to the work. You serve the notice, your neighbour either consents or appoints a surveyor, and we work to the award that follows. We are not party wall surveyors and never act as one.
Havering homeowners choose GS Renovation for steelwork because we bring the engineer, the propping, the demolition and the building control sign-off together under one team. With 30+ years across RM postcodes, we know how these interwar semis are built, we coordinate around the party wall award properly, and we leave the opening square, supported and ready for finishing.

Punctual, worked hard, and did exactly what he was asked and what he said he would do. Overall, a very high quality job. Will use again.
FAQ
What sits behind the walls drives it far more than the address does. We survey the RM1 property, confirm the load path, and only then price RSJ and steel beam installation for your Havering home. Older stock across Havering adds making good, and awkward access adds labour, so both are itemised rather than absorbed. GS Renovation would rather explain a Havering figure than defend it later on site, so ring 07472 424 226 or email info@gsrenovationltd.co.uk first. 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.
Sooner if the survey happens sooner. The constraint on starting RSJ and steel beam installation at an RM1 address is rarely labour; it is approvals and material lead times, both of which GS Renovation sets running as soon as the Havering scope is agreed. We do not open a house we cannot then finish. Email info@gsrenovationltd.co.uk and we will book a free Havering visit. Ring 07472 424 226 and we will confirm the next free week in Havering or Barking and Dagenham.
You get the Havering Council completion certificate, the guarantee and a number that still answers. Installations carry a five year guarantee, and if something needs attention at your RM1 property after RSJ and steel beam installation is signed off you reach the same people who did the Havering work. GS Renovation does not route aftercare through a call centre. Nothing about that is a brochure line. Ring 07472 424 226 whenever a Havering issue arises. The guarantee covers Havering installations for five years.
Almost any wall can be opened up, but what the beam has to carry and what it bears onto change completely. In a Havering property the load path matters more than the wall itself, which is why an engineer assesses the RM1 address before we quote.
More demanding in places, but not harder for a team that works on them constantly. RSJ and steel beam installation at an RM1 address of that age needs proper investigation before design and more care in the finishing afterwards. GS Renovation allows for both in the Havering programme. The structural stage itself is usually no more complex than in a newer Havering property. Ask on 07472 424 226 how RSJ and steel beam installation runs on a comparable RM1 house in Havering.
Very likely, yes. In Havering's semi-detached homes the dividing wall or chimney breast is often shared with your neighbour, so the Party Wall Act applies and you must serve notice before work starts. You serve the correct notices, agree a schedule of condition, and coordinate timing so the steel beam goes in without dispute.
Both are within our normal working area. RSJ and steel beam installation is not priced by distance within East London, so a Havering homeowner and a Barking and Dagenham one get the same treatment and the same free survey. GS Renovation is on Havering sites most weeks. Call 07472 424 226 to check availability for your RM1 property. We will be straight with you if it is too far. Aftercare visits afterwards are equally straightforward wherever the property actually sits.
