Planning steel beam replacement & repair in Feltham

For homes in Feltham and the TW2, TW3, TW4, TW5 and TW6 districts, we handle steel beam replacement & repair from survey to sign-off. Our coverage runs across London, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.

We start with a survey visit, arrange an engineer's inspection, then carry out whatever repair the engineer specifies, from new bearings to strengthening or full replacement. We handle building control and the temporary propping, and you get an itemised written quote before anything starts.

What to expect

  • 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.
  • 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.
  • 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.
  • Shop beams over old shopfronts are a common repair job. They often carry the whole front wall of the upper floors, sit behind fascias where rain gets in, and may have been cut or altered when shopfronts were replaced in the past.
  • Signs that a beam is struggling include diagonal cracks running up from its ends, a visible dip along its length, doors above that start binding, and rust staining through paint or plaster. Any one of these is worth an engineer's look.

What happens, step by step

  1. Free visit

    A short visit to Feltham 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 the local council's building control team, 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.

Building control and neighbours in Feltham

For Feltham, building control is provided by the local council's building control team, 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.

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.

Local questions answered

Do you cover Feltham for steel beam replacement & repair?

Yes. We carry out steel beam replacement & repair in Feltham and the TW2, TW3, TW4, TW5 and TW6 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 a party wall agreement for steel beam replacement & repair in Feltham?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.

Can a rusty steel beam be repaired?

Often, yes. Surface rust can usually be cleaned back to sound steel and treated with a protective coating. Where corrosion has eaten into the flanges or web, the engineer works out the remaining strength and decides whether plating will restore it or the beam needs replacing. The source of the moisture must be fixed as well.

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.

Can you replace a steel beam without taking the ceiling down?

Usually only part of the ceiling needs to come down. The boxing and a strip of ceiling either side of the beam are removed so props can go in and the old steel can come out. The rest of the room is protected, and the disturbed area is replastered to blend with the existing finish.

Can you work on older or listed homes in Feltham?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
