About our load-bearing wall removal service in Derry/Londonderry

If you live in Derry/Londonderry, load-bearing wall removal can usually be planned and priced after a single survey visit. The wider Derry City and Strabane area is covered as well. We cover BT47 and BT48, and we fix the price in writing once the layout and scope are agreed.

Most homes built before the 1970s have at least one internal wall that carries the floor joists, a wall upstairs or part of the roof. Taking it out is very doable, but the weight it carries has to go somewhere. A steel beam picks that load up and passes it down through padstones into walls or columns that can take it.

Key points for your project

  • Each end of the beam needs a solid bearing. Padstones spread the point load into the masonry below, and if the wall underneath is weak the engineer may call for a steel column or a new pad foundation instead.
  • Most single-wall removals in a typical house take two to five working days on site for the structural part. Plastering, drying out and decorating follow on, and building control visits fit around those stages.
  • Whether a wall is load-bearing is not always obvious. Joists running across the wall, a wall directly above, or the wall sitting on a footing in the floor are common clues, but the engineer's check on site is what settles it.
  • Temporary works matter as much as the beam. Props, spreaders and needles carry the house while the wall is out, and they are positioned so the floor below can take them too.
  • If the wall carries a chimney breast, a wall upstairs and floor joists all at once, the engineer may specify a heavier beam or two beams side by side. The quote reflects that once calculations are back.

Four stages, one team

  1. Survey in Derry/Londonderry

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. Building control

    A full plans application or building notice goes to Derry City and Strabane District Council under the Building Regulations (Northern Ireland) 2012 before work begins.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Local questions answered

What happens at the survey visit in Derry/Londonderry?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

Do I need a party wall agreement for load-bearing wall removal in Derry/Londonderry?

There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.

What does the price include?

Our written quote is itemised, so you can see the calculations, building control fees, propping, steel, padstones, labour, fire protection and making good set out line by line. The price is fixed in writing once the layout and scope are agreed.

How do I know if my wall is load-bearing?

Clues include floor joists that run across the top of the wall, a wall directly above it upstairs, and a wall that is solid brick or block rather than a hollow stud partition. None of these is proof on its own. A structural engineer checks on site and confirms it before any work is planned.

Do I need planning permission to remove an internal wall?

Usually not, because internal alterations to a house are not normally development needing planning permission. Listed buildings are different and need listed building consent, and flats normally need the freeholder's or landlord's written consent.
