Steel columns & posts in Croydon: how it works

Need steel columns & posts in Croydon? We also cover the surrounding towns and villages in London. We survey the property, arrange the engineer's design, deal with local building control, fit the steel and make good, all under one quote for CR0, CR2, CR7, CR9 and SE19 addresses.

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.

What to expect

  • 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.
  • Placing a post well can make an open-plan room work better. It can mark the edge of a kitchen island, frame a dining area or line up with a worktop end, so it reads as part of the design rather than an obstruction.
  • Columns on upper floors cannot simply stand on joists. The load has to be traced down through the building to the ground, which can mean a column directly below, a beam to collect it, or a redesign of the layout.
  • Older properties sometimes have cast iron columns, timber posts or brick piers doing this job, especially in cellars and former shops. Their condition and capacity are often unknown, so the engineer assesses whether they can stay or need replacing with new steel.
  • The noisiest part is cutting the floor and digging the pad, usually a day's work. The concrete then needs time to gain strength, so the column is often fitted on a later visit once it has cured enough to take load.

How the job runs in Croydon

  1. Free visit

    A short visit to Croydon to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. 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.

Building control and neighbours in Croydon

For Croydon, building control is provided by the local council's building control team, 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.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered

Can you work on older or listed homes in Croydon?

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.

Who approves steel columns & posts in Croydon?

Structural work in Croydon needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.

Does a steel column need a foundation?

Almost always, yes. A column puts a concentrated load onto a small patch of ground, and most floor slabs are not designed for that. The engineer specifies a concrete pad of a set size and depth, building control usually inspects the hole before concrete is poured, and the column is bolted down once the pad has cured.

Can I put a steel post in the middle of a beam?

Yes, a central post is a common way to support a long beam, and it often lets the engineer specify a shallower steel. The post needs its own foundation and has to sit somewhere that works with the room layout. The engineer compares a post against a single deeper beam and specifies whichever suits the loads and the space.

How thin can a steel support post be?

It depends entirely on the load, the height and how the post is restrained, so there is no standard size. Hollow sections often give the slimmest look for a given strength, and an engineer can sometimes reduce the section by adding restraint partway up. They specify the exact section after calculating the load.

Do you also work near Croydon?

Yes. We also cover nearby towns including South Croydon, Wallington, Carshalton and Mitcham.
