RSJ and Steel Beam Installation Hanwell

GS Renovation installs RSJs and steel beams across Hanwell, from the bay-fronted Victorian terraces near the Brent valley to the Edwardian rows around Brent Lodge Park in W7. We remove load-bearing walls and open up these period homes safely and correctly.

In Hanwell, a steel beam for one opening typically costs £1,500 to £4,000 fitted and signed off, or £2,500 to £6,500 or more for a full knock-through with the engineer's fee and making good (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Hanwell.

How the job runs

1. Free site survey at your Hanwell address and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Ealing Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. Props go in, the opening is cut and the beam is set on padstones, packed tight above.
4. Building control inspects the steel before it is covered. We make good, and the completion certificate follows.

Load-bearing wall removal in Hanwell terraces

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.

Housing in Hanwell

Hanwell counts roughly 10,370 homes for Council Tax; 36% are older than 1919, 34% interwar and 30% post-war, with 42% flats and 58% houses. A beam in a terrace in Hanwell often bears on the party wall, bringing in the Party Wall Act, and 42% of homes here are terraced.

One Hanwell street, three kinds of wall under the beam

Hanwell's housing went up over a long spread of years, and the wall a beam sits on reflects the period it was built in. 36% of homes here were built before 1919, 34% between 1919 and 1939 and 30% after 1945. On a single W7 street that can mean a solid brick terrace laid in soft lime mortar next to an interwar house with a cavity, and a post-war infill with a block inner leaf. Each needs a different bearing: a long padstone across a solid wall, a padstone on the inner leaf with the cavity kept clear, or a spreader that stops lightweight blocks crushing under a point load.

The approval route rewards getting that detail onto paper early. On an Ealing full plan application the plans are checked within 10 working days and a list of observations is produced. Put photographs of both opened-up bearings and the structural engineer's padstone detail into the first submission, so the observations deal with the design rather than asking questions the photographs would have answered. We order the steel only after the observations are answered, because a change at the bearing often changes the length of the beam, and a beam cut to the wrong length is a wasted delivery.

Padstones and party walls in Hanwell W7

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 you serve your neighbour notice as building owner before work starts. We flag this early and give you the drawings the notice needs, so the notice period runs alongside the engineering, keeping your project on schedule and your neighbour relations intact.
