RSJ and Steel Beam Installation Edmonton

GS Renovation installs steel beams and RSJs throughout Edmonton, from the bay-fronted Victorian and Edwardian terraces of N9, which rely on solid load-bearing walls to hold up the floors above, to the interwar and post-war houses around them. We remove walls safely, prop the structure and bring the whole job through building control.

In Edmonton, 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 Edmonton.

How the job runs

1. Free site survey at your Edmonton address and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Enfield 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.

Removing load-bearing walls in Edmonton terraces

The wall between the front and middle reception in an Edmonton terrace almost always carries load, and so does the wall into the rear closet wing. Before anything comes down, we have a structural engineer size the beam for the span and the weight above, then we install temporary props to hold the floor joists and any masonry while we work. The demolition is staged, not rushed, so the house stays stable throughout.

Once the opening is formed, the new RSJ bears onto concrete padstones spread across the remaining brickwork so the point loads do not crush the wall below. We check the bearings, pack and pin the beam tight to the joists above, then make good. Every beam we fit in N9 is installed to the engineer's drawings and inspected, so you have a proper paper trail for the work.

Housing in Edmonton

Roughly 18,850 dwellings sit on the valuation list for Edmonton. 51% are houses and 49% flats, and by age 29% predate 1919, 23% are interwar and 48% post-war. 45% of homes here are terraced; a beam in a terrace in Edmonton often bears on the party wall, bringing in the Party Wall Act.

Getting steel into Edmonton terraces and upper floor flats

45% of homes in Edmonton are terraced houses and only 5% are semi-detached or detached, so a new beam will usually have no side gate to come through. The steel arrives through the front door, along the hall and round the foot of the stair. Before the beam is ordered, measure that route, because the longest length that will turn into the room decides whether the engineer designs one section or two bolted together on site. A spliced beam needs its joint designed and inspected like any other connection, so settle the delivery route before the calculations are signed off.

49% of homes in Edmonton are flats, and a beam in an upper floor flat raises a question that a house does not. The temporary props that hold the floor above while the wall comes out stand on your floor, and that floor is the ceiling of the flat below. The structural engineer we appoint may need the props carried down through the lower flat to solid ground, which means agreeing access with its owner and protecting their ceiling. Raise the propping route at the first visit, since a neighbour who has not agreed access can halt the programme on the first morning.

Party wall notices on Edmonton's shared walls

Edmonton terraces sit in continuous rows, which means the wall you share with next door, and often the chimney stack, is a party wall under the Party Wall Act. When a new beam bears into that shared wall, or when we cut pockets for padstones, your neighbour is legally entitled to notice. We flag this early so you can serve the correct notices before the steel goes in and avoid any dispute part way through.

We are used to coordinating this on tight N9 plots where houses touch on both sides. Getting the party wall paperwork sorted in good time keeps the programme moving and protects you if a neighbour later raises a concern about cracking or settlement. It is a routine part of structural work on Edmonton's terraced stock: you serve the notices as building owner (or your surveyor does), and we give the surveyors the engineer's drawings and build to any award.
