About our steel beam replacement & repair service in Portadown
Portadown has a mix of housing, and steel beam replacement & repair needs a slightly different approach in each. The wider Armagh City, Banbridge and Craigavon area is covered as well. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
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
- 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.
- 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.
- A proper assessment means opening the boxing at the ends and along the span so the engineer can see the steel. In buildings from before 2000, old boxing can contain asbestos insulating board, so it is checked before anyone cuts into it.
- 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.
- 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.
How the job runs in Portadown
Survey in Portadown
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
A full plans application or building notice goes to Armagh City, Banbridge and Craigavon Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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 control and neighbours in Portadown
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Portadown that is Armagh City, Banbridge and Craigavon Borough Council. We submit a full plans application or building notice before work starts and book the inspections.
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.
Steel beam replacement & repair in Portadown: your questions
How soon can steel beam replacement & repair start in Portadown?
Start dates depend on the engineer's calculations, the building control approval and any agreement needed with neighbours. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
Who approves steel beam replacement & repair in Portadown?
Structural work in Portadown needs a full plans application or building notice to Armagh City, Banbridge and Craigavon Borough Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
How do I know if my steel beam is failing?
Look for cracks spreading from the ends of the beam, a dip you can see along its length, sticking doors or sloping floors above, and rust stains coming through the boxing. These signs do not always mean the steel is failing, but they do mean an engineer should inspect it and find the cause.
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.

Yes. We also cover nearby towns including Craigavon, Banbridge, Dungannon and Newry.
