What basement & cellar steels involve in Dungannon
Our basement & cellar steels service in Dungannon covers everything from the first visit to the completion paperwork. We also cover the surrounding towns and villages in Mid Ulster. Postcode districts we cover here include BT71.
Turning a cellar into a habitable room, or digging a new basement, nearly always means moving or removing walls that hold up the rest of the house. Steel beams and columns take over that support, often while the existing walls are being deepened by underpinning and the space is protected against water.
Things to plan for
- Getting steel into a basement means lowering it through a lightwell, a stair opening or a temporary hole in the ground floor. Long beams may be designed in bolted sections so they can be handled in tight below-ground spaces.
- Basements can stay damp even with waterproofing in place, so steel used below ground is protected against corrosion as the engineer specifies. That might mean an upgraded paint system or galvanising, particularly where steel sits close to external walls.
- Converting a cellar into a habitable room is building work needing building regulations approval, covering structure, fire escape, ventilation and damp protection. Digging out a new basement may also need planning permission, depending on the council and the scale of the work.
- Temporary works for basements are more involved than for a single opening. The design covers propping the house above, supporting the sides of the excavation, and keeping loads off freshly cast concrete until it has gained strength.
- Underpinning deepens the existing foundations so walls can go lower, and a specialist carries it out in a strict bay-by-bay sequence. Steelwork has to fit around that sequence, which is why the engineer plans the two together from the start.
How the job runs in Dungannon
Survey in Dungannon
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 Mid Ulster District 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 rules for Dungannon
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Dungannon that is Mid Ulster District Council. We submit a full plans application or building notice before work starts and book the inspections.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.
Basement & cellar steels in Dungannon: your questions
Do you also work near Dungannon?
Yes. We also cover nearby towns including Cookstown, Portadown, Craigavon and Magherafelt.
Who approves basement & cellar steels in Dungannon?
Structural work in Dungannon needs a full plans application or building notice to Mid Ulster District Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Do you do the underpinning for a basement?
Underpinning is specialist work, and we coordinate the steelwork with the underpinning contractor rather than carrying it out ourselves. The engineer designs the steel and the underpinning sequence together, so beams, columns and new foundations fit the order in which the walls are deepened.
How long does it take to fit steels in a basement?
Each stage of steelwork usually takes a few days, but it happens at several points through a basement project rather than all at once. The overall programme is set by the excavation, underpinning and waterproofing, and the steel is installed whenever the sequence reaches it.
Can I stay at home while basement steels are installed?
Many people do, particularly for cellar conversions where the dig is limited. Expect noise, dust and deliveries during the heavier stages, and some rooms above may be out of use while props are in place. For large excavations, moving out for part of the programme can be more comfortable.
