About our steel columns & posts service in Slough

Slough has a mix of housing, and steel columns & posts need a slightly different approach in each. Our coverage runs across Berkshire, so nearby villages are included too. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

Sometimes the right support for a beam is not a wall at all. A long span can be broken in two with a slim post in the middle, a beam can land on a column where the masonry below is weak, or the corner of an L-shaped opening can be held up by a single post instead of a brick pier.

What to expect

  • A tall, slender column can buckle under load before the steel itself is overstressed. That is why the engineer checks the height between restraints as well as the weight carried, and why a taller column may need a heavier section.
  • 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.
  • 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.
  • Exposed columns are commonly protected with intumescent paint applied to the thickness the specification calls for, which keeps a slim profile. Boxed columns are clad in fire-rated plasterboard and finished with corner beads, skim and a skirting to match the room.
  • 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.

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

    We submit a building notice or full plans application to Slough Borough Council, so approval is in place before the wall is touched.

  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.

Approvals in Slough

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either Slough Borough Council or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Steel columns & posts in Slough: your questions

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

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 much do steel columns & posts cost in Slough?

As a guide, budget £560–£1,680 per column including VAT for steel column or post in Slough, based on published UK cost guides adjusted for prices in the South East (+12%). 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.

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.

Will a column interfere with underfloor heating?

It can, because the pad has to be dug through the floor where pipes may run. We trace heating loops, drains and cables before cutting and, where possible, move the column position slightly to miss them. If a loop has to be cut, it is repaired and pressure tested by a heating engineer before the floor is reinstated.

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.
