Steel columns & posts in Newtownabbey: how it works

Newtownabbey has a mix of housing, and steel columns & posts need a slightly different approach in each. We also cover the surrounding towns and villages in Antrim and Newtownabbey. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

We arrange the engineer's design, building control, the pad foundation, propping, supply and fixing of the column, and the boxing or finishing afterwards. You receive an itemised written quote, and the price is fixed in writing once the position, specification and scope are agreed.

Worth knowing before you start

  • While the existing support is removed or the new column goes in, props hold the beam and the structure above. They are only taken out once the column is fixed, packed tight at the head and grouted at the base.
  • Steel at floor level can corrode if it sits in damp. The detail at the base is designed to keep damp away, using grout, protective paint and the floor's damp-proof membrane, and a column in a cellar or garage may need a heavier coating.
  • A post is needed when a beam has nothing adequate to bear on, or when a span is long enough that a central support gives a shallower, lighter beam. The engineer weighs up a column against a deeper beam for each layout.
  • Adding a structural column is building work that building control needs to approve, with the pad usually inspected before concrete and the column before it is covered. The completion certificate at the end is the record to keep for any future sale.
  • Underfloor heating pipes, drains and cables in the slab can sit right where a pad is wanted. These are traced before cutting, and the column position is adjusted where possible rather than damaging a heating loop or drain run.

Four stages, one team

  1. Look and measure

    We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. Building control

    A full plans application or building notice goes to Antrim and Newtownabbey Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building rules for Newtownabbey

Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Antrim and Newtownabbey Borough Council covers Newtownabbey. The engineer's calculations support the application, and a completion certificate is issued after the final inspection.

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.

Questions about steel columns & posts in Newtownabbey

Can I stay at home while the work is done in Newtownabbey?

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.

Do you also work near Newtownabbey?

Yes. We also cover nearby towns including Carrickfergus, Castlereagh, Lisburn and Antrim.

Can you replace an old timber or cast iron post?

Usually, yes. Old posts in cellars, garages and converted shops are often undersized, rotten or of unknown strength. The engineer assesses the load they carry and specifies a new steel column and pad. The structure is propped while the old post comes out, and the new column is packed tight before the props are removed.

Can a steel post replace a supporting wall?

Yes, in many layouts a wall can come out with a beam above it and one or more posts taking the beam's load down to the ground. This keeps most of the openness while shortening the span. The engineer decides how many posts are needed and where they can go.

What is the difference between a column and a padstone?

A padstone is a block bedded into a wall to spread a beam's load into the masonry beneath. A column replaces the need for a wall altogether, carrying the load down to its own foundation. Where the wall below a beam end is too weak for a padstone, the engineer may call for a column instead.

Can you work on older or listed homes in Newtownabbey?

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.
