What load-bearing wall removal involves in Portsmouth

Our load-bearing wall removal service in Portsmouth covers everything from the first visit to the completion paperwork. Our coverage runs across Hampshire, so nearby villages are included too. Postcode districts we cover here include PO1, PO2, PO3, PO4 and PO5.

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.

Things to plan for

  • Building control is needed because removing a structural wall is controlled building work. Doing it without approval can cause problems when you come to sell, and putting it right afterwards costs far more than doing it properly first time.
  • 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.
  • Older homes can hide surprises such as weak lime mortar, timber lintels or a wall with no proper footing. Where the engineer needs something extra, we price it before any work starts rather than after.
  • 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.
  • The beam size depends on the span, what sits above and how the ends are supported. Two walls that look the same can need very different steel, which is why every beam is sized from calculations rather than guessed.

What happens, step by step

  1. Survey in Portsmouth

    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

    We submit a building notice or full plans application to Portsmouth City Council, so approval is in place before the wall is touched.

  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.

Approvals in Portsmouth

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either Portsmouth City Council or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about load-bearing wall removal in Portsmouth

Do you cover Portsmouth for load-bearing wall removal?

Yes. We carry out load-bearing wall removal in Portsmouth and the PO1, PO2, PO3, PO4 and PO5 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Can I stay at home while the work is done in Portsmouth?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.

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.

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.

What happens if the wall is shared with my neighbour?

In England and Wales, cutting into a party wall to take the end of a beam is covered by the Party Wall etc. Act 1996, and notice must be served on the neighbour before work starts. Scotland and Northern Ireland have no equivalent Act, so the title deeds and the general law apply instead.

Do you also work near Portsmouth?

Yes. We also cover nearby towns including Gosport, Fareham, Havant and Waterlooville.
