About our load-bearing wall removal service in Lisburn and Castlereagh

Load-bearing wall removal means taking out a wall that holds up floors, roof loads or walls above it, and replacing that support with a steel beam sized by a structural engineer. The beam sits on padstones at each end, the weight above is held on temporary props while the wall comes out, and building control inspects the finished work.

We carry out load-bearing wall removal throughout Lisburn and Castlereagh, for homeowners, landlords and builders who need the structural part done properly. Coverage takes in Lisburn and everywhere in between. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.

Things to plan for

  • 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.
  • The finished opening should be signed off with a completion certificate from building control. Keep it with your house documents, as solicitors ask for it when the property is sold.
  • A beam can sit below the ceiling with a small boxed downstand or be set up into the floor void so the ceiling runs flat. A flush beam usually needs more work to the joists and costs more.
  • 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.
  • Homes built before 2000 may contain asbestos in textured ceilings, boxing or old boards. Where there is a risk, a survey of the area being disturbed is arranged before the wall comes out.

Four stages, one team

  1. Free visit

    A short visit to Lisburn and Castlereagh to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

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

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building control and neighbours in Lisburn and Castlereagh

Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Lisburn and Castlereagh City Council covers Lisburn and Castlereagh. The engineer's calculations support the application, and a completion certificate is issued after the final inspection.

Northern Ireland has no Party Wall Act, so there is no statutory notice to serve. Where the steel bears into a shared wall, the title deeds and the general law apply, and agreeing the work with your neighbour in writing first is good practice.

Load-bearing wall removal in Lisburn and Castlereagh: your questions

Do you cover Lisburn and Castlereagh for load-bearing wall removal?

Yes. We carry out load-bearing wall removal in Lisburn and Castlereagh. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

What happens at the survey visit in Lisburn and Castlereagh?

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.

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.

Can I stay in the house while the wall is removed?

In most cases yes. The work area is screened, floors are protected and the house stays usable, though the rooms either side of the wall will be out of action for a few days and there will be some noise and dust.

Who sizes the steel beam?

A structural engineer. They look at the span, the loads from floors, walls and roof above, and the bearings at each end, then specify the beam, padstones and any columns. We arrange those calculations, or work to calculations you already have.

Will the beam show once the job is finished?

It depends on the design. Most beams sit just below the ceiling and are boxed in with plasterboard, leaving a small step. A beam can be set up into the floor void for a flat ceiling, which takes more work, or left exposed and painted where you want an industrial look.
