Structural alterations, new openings and steel support in Ealing. Trusted, professional, 30+ years' hands-on experience.
GS Renovation carries out structural alterations across Ealing, from new openings in Acton's Victorian terraces to replacement joists and underpinning under 1930s semis near Ealing Common. Drawing on 30+ years in W3, UB1 and UB6, We build supported openings to the engineer's design, renew failed timbers and stabilise foundations to current Building Regulations.

Whether you are forming a wide opening into a side-return extension or knocking a doorway through a solid W13 dividing wall, the principle is the same: the masonry above must be caught and carried. Our engineer sizes the lintel or steel for the span and the load coming down onto it, and specifies padstones so the beam bears onto sound brickwork rather than crushing the wall beneath. Nothing is left to guesswork.
Ealing's older terraces frequently reveal tired structure once opened up: sagging floor joists eaten by rot near the closet wing, or lintels that have shifted over a century. We replace joists like-for-like or upsized, renew defective lintels and pin masonry as needed. Temporary propping supports the structure throughout, and the load is transferred onto the new steel or timber only when everything is set and bearing correctly.
The clay subsoils under much of Ealing move with the seasons, and mature street trees near Walpole Park and along the older Hanwell roads can draw moisture and cause subsidence. Where foundations have dropped, we underpin in carefully sequenced bays, excavating and casting new concrete beneath the existing footings in a hit-and-miss pattern so the wall is never left unsupported. The engineer designs the depth and mix to suit the ground.
Structural alterations of this kind are notifiable under the Building Regulations, and Ealing Council building control inspects the works as they proceed. Underpinning and new openings on a party wall also fall under the Party Wall Act, so you serve notice on the adjoining owner before starting. We coordinate the engineer and the inspections so the whole job is compliant and properly certified.

FAQ
We would rather not, because a phone figure is a figure that changes. What structural alterations cost at a W3 address depends on structure and condition we can only see on site, particularly in late Victorian and Edwardian housing. GS Renovation will happily talk through the likely scope on 07472 424 226, then survey the Ealing property free of charge. The written quotation follows that visit. Nothing is owed for the W3 visit, in Ealing or anywhere beyond it. As a rough guide, structural alterations in London ranges from roughly £1,500 for a simple opening to £15,000 or more where underpinning or major works are involved (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.
Less than most people expect, because it runs alongside the work. GS Renovation submits the structural alterations application, books the Ealing Council inspections and attends them at your W3 property, so the Ealing programme absorbs them. The one thing that does add time is a full plans approval, which we advise on where a late Victorian and Edwardian structure warrants the certainty. Ring 07472 424 226 and GS Renovation will advise which route suits a W3 home in Ealing.

The structural engineer. GS Renovation is a contractor: we appoint and coordinate the engineer, arrange the temporary works, and build to their design at your Ealing address. We do not produce calculations ourselves, and any builder claiming to is worth questioning.
Almost all, which is exactly why the survey matters. Structural alterations at a W3 address of that age is priced on what we find rather than on a standard detail, and GS Renovation has done enough of them across Ealing and Hillingdon to know where to look. The 31 public MyBuilder reviews cover the same work. Ring 07472 424 226 for recent examples. Ask on 07472 424 226 what structural alterations usually finds at a W3 address of that age.
Not always. Seasonal clay movement near mature trees is common across Ealing, and some cracking is superficial. A structural engineer's inspection determines whether the foundations have actually subsided and whether underpinning, root management or repair is the right fix. If underpinning is needed, we carry it out in sequenced bays under Ealing Council building control, with any party wall notices served first.
