About our steel beam replacement & repair service in Portslade
Planning steel beam replacement & repair in Portslade? Our team covers BN3 and BN41 and the streets around them. Portslade is around 3.5 miles from Brighton, and we cover both. You get one written quote for the calculations, approvals, propping, steel and making good.
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.
Key points for your project
- Repairs are usually more contained than a new opening because the room layout stays the same. The main disruption is stripping the boxing, propping the floor above and the dust from cutting steel, with the ceiling and walls around the beam replastered afterwards.
- Like-for-like repainting needs no approval, but strengthening, rebuilding bearings or replacing a beam is structural work that falls under building control. Where an earlier beam went in without approval, a regularisation application in England and Wales can be used to seek retrospective sign-off.
- A repair only lasts if the cause is dealt with too. A leaking roof, blocked gutter or bridged damp-proof course that rusted the beam needs fixing first, otherwise new protective coatings will break down in the same way.
- 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.
- Replacing a beam that is already carrying load is more delicate than fitting a new one. Props go in on both sides before anything is cut, with spreaders above and below, and the old steel is often cut into sections to lift it out safely.
Four stages, one team
Survey in Portslade
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.
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.
Building control
We submit a building notice or full plans application to Brighton & Hove City Council, so approval is in place before the wall is touched.
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.

Building rules for Portslade
For Portslade, building control is provided by Brighton & Hove City 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.
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 Portslade for steel beam replacement & repair?
Yes. We carry out steel beam replacement & repair in Portslade and the BN3 and BN41 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 you also work near Portslade?
Yes. We also cover nearby towns including Hove, Brighton, Worthing and Rottingdean.
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.
Is it cheaper to repair or replace a steel beam?
Repair is often less disruptive and can cost less, but only when the engineer confirms it will do the job. Heavily corroded or badly undersized beams may need replacing anyway, and plating in awkward positions is not always cheaper. We price the option the engineer specifies in an itemised written quote.
Can you work on older or listed homes in Portslade?
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.
