Steel beam installation, RSJ and structural alterations in Hanwell. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Hanwell, from the bay-fronted Victorian terraces near the Brent valley to the Edwardian rows around Walpole Park in W7. With over 30 years of structural experience in Ealing, we remove load-bearing walls and open up these period homes safely and correctly.

The typical Hanwell project takes out the wall between the front and middle reception rooms, or the wall closing off the rear closet wing, to create a single flowing space. In these Victorian and Edwardian terraces those dividing walls are usually load-bearing and often carry a chimney breast, so nothing comes out until a structural engineer has sized the steel and we have temporary props holding the loads above.
We work in a careful, staged sequence: prop the floor and ceiling, cut back to solid brickwork, form the bearings, lift the RSJ into position and set it onto padstones that spread the load into the wall. Building control inspects the beam and the padstones before we case the steel and make good. The result is a clear opening that carries the house properly.
Steel beams need somewhere solid to sit. We cast or place concrete padstones under each bearing so the point loads pass safely into the wall and the foundation below rather than crushing the old brickwork. The engineer specifies the padstone size and the required bearing length, and we photograph everything for your building control file so the sign-off is straightforward.
Many Hanwell terraces share their side wall and chimney stack with next door in a party wall. Where a beam bears into that shared wall or you cut into it, the Party Wall Act applies and your neighbour must be served notice before work starts. We flag this early so the notice period runs alongside the engineering, keeping your project on schedule and your neighbour relations intact.
Hanwell homeowners choose GS Renovation because we treat steelwork as structural engineering, not guesswork. We coordinate the engineer, the temporary propping, the padstones and the Ealing Council building control inspections as one accountable job, and we understand the shared party walls in these W7 terraces. Over 30 years of beams installed across West London stand behind every opening.

FAQ
Set aside the structural element, the finishing trades and the approvals as three separate amounts. That is how the RSJ and steel beam installation quotation for a Hanwell home is laid out, and it is why the W7 survey happens before any figure is discussed. The engineer's fee, where RSJ and steel beam installation needs a design, is shown rather than buried. Ask GS Renovation on 07472 424 226 for the current position in Ealing. The survey at the W7 property is free, in Hanwell and across Ealing. 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.
Ring 07472 424 226 and we will tell you honestly rather than promise a date we cannot hold. Typically RSJ and steel beam installation is booked a few weeks ahead for Hanwell homes, and the free survey at W7 is what gets you into the schedule. Where Ealing Council approval is required we submit while you decide. GS Renovation does not take deposits to reserve Ealing slots. The Hanwell start date is confirmed in writing once the Ealing scope is agreed.
It helps, provided the firm is genuinely local rather than badged that way. Knowing how solid-wall Victorian terraces with original chimney breasts and suspended timber floors are built means RSJ and steel beam installation at a W7 address is priced from experience instead of caution, and a team already working in Ealing can reach your Hanwell property quickly. GS Renovation is on sites nearby most weeks. Check insurance and reviews whoever you choose. Ring 07472 424 226 and ask where we are currently working. Insurance and Ealing references are available beforehand.
The bearings and padstones before they are covered, and the beam itself against the engineer's calculations. Ealing Council will want to see the steel in place and correctly supported at your Hanwell property before it is boxed in, so the inspection has to be booked at the right moment.
A different method, not a different quality. What changes on RSJ and steel beam installation in solid-wall Victorian terraces with original chimney breasts and suspended timber floors is the amount of investigation beforehand and the care in reinstatement afterwards at the W7 address. GS Renovation programmes both into the Hanwell job. The structural stage in between runs much as it would anywhere in Ealing. Email info@gsrenovationltd.co.uk and we will explain what RSJ and steel beam installation at a W7 property in Hanwell involves before you commit yourself to anything.
Yes to building control, which is a building regulations matter, not planning permission. A structural engineer sizes the beam and building control inspects it before it is hidden. If the wall you are working on is shared with your neighbour, which is common in Hanwell terraces, the Party Wall Act also applies and you must serve notice before we begin.
All of them, W7 included, along with the neighbouring parts of Ealing. GS Renovation does not price RSJ and steel beam installation differently by postcode, and there is no travel charge within Hanwell and the W7 area. Ring 07472 424 226 with your address and we will confirm immediately. The survey that follows is free and carries no obligation. Building control goes through Ealing Council wherever the property sits. Small jobs and full projects are quoted on precisely the same written terms.
