Planning steel beam replacement & repair in Swindon

For homes in Swindon and the SN1, SN2, SN3, SN4 and SN5 districts, we handle steel beam replacement & repair from survey to sign-off. Our coverage runs across Wiltshire, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.

Not every steel beam was put in properly. Some were fitted decades ago without calculations, some sit on crumbling brick or timber packing, and some have rusted where water reached them through a leaking roof, a shopfront or a damp wall. Cracks in the plaster above, doors that stick or a visible dip are common warning signs.

What to expect

  • Beams fitted without calculations, whether decades ago or more recently without approval, may be smaller than the loads require, particularly in shop conversions and older knock-throughs. An engineer can check the existing section against the actual loads and say whether it is adequate.
  • Older beams were often left with no fire protection or boxed in ordinary materials. When a beam is repaired or replaced, the fire protection is brought up to what the engineer and building control specify, commonly fire-rated plasterboard or intumescent paint.
  • Whether to strengthen or replace is the engineer's decision. Plating, where steel plates are fixed to the flanges, can add capacity without removing the beam, but it is not suitable for every section, connection or level of damage.
  • The full scope is sometimes clear only once the steel is exposed. We price the inspection and opening up first where needed, then provide an itemised quote for the repair the engineer specifies, so you are not committing to work before the problem is understood.
  • Corrosion usually starts where water reaches the steel: under a leaking flat roof, behind a shopfront fascia, in a damp external wall or at a cellar ceiling. Light surface rust can often be cleaned and treated, while heavy loss of section changes the beam's strength.

How the job runs in Swindon

  1. Free visit

    A short visit to Swindon 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

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

  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.

Approvals in Swindon

For Swindon, building control is provided by Swindon Borough Council, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Questions about steel beam replacement & repair in Swindon

Do you cover Swindon for steel beam replacement & repair?

Yes. We carry out steel beam replacement & repair in Swindon and the SN1, SN2, SN3, SN4 and SN5 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Do I need building control to replace a steel beam?

Yes, replacing or strengthening a structural beam is building work. In England and Wales it needs building regulations approval, in Scotland a building warrant before work starts, and in Northern Ireland an application to council building control. Simple redecoration or treating light surface rust without altering the structure does not normally need approval.

How long does it take to replace a steel beam?

Anything from a day or two to around a week on site, depending on what the engineer specifies. Rebuilding a crushed bearing can be quick, while cutting out an old beam and fitting a new one in a typical room takes longer. Plastering and redecoration follow once building control has inspected the new steel.

What does it mean to plate a steel beam?

Plating means fixing extra steel plates to the beam, usually along the flanges, to increase its strength or stiffness without taking it out. The plates are bolted or welded according to the engineer's design. It suits some beams well, but not all, and the engineer checks the connections and bearings before specifying it.
