About our steel beam replacement & repair service in Coleraine
We carry out steel beam replacement & repair in Coleraine, covering the BT52 postcode district. Our coverage runs across Causeway Coast and Glens, so nearby villages are included too. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
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.
- Missing paperwork for an old beam often surfaces when a house is being sold and the buyer's surveyor asks for calculations. An engineer's inspection, any remedial work and a regularisation or completion certificate together answer those questions.
- 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.
- 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.
- 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.
Four stages, one team
Free visit
A short visit to Coleraine to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
A full plans application or building notice goes to Causeway Coast and Glens Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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 Coleraine
Building control in Coleraine is run by Causeway Coast and Glens Borough Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.
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 Coleraine: your questions
What happens at the survey visit in Coleraine?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Can I stay at home while the work is done in Coleraine?
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.
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.
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.
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.
How much does steel beam replacement & repair cost in Coleraine?

The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
