What steel columns & posts involve in Caldicot
For homes in Caldicot and the NP26 district, we handle steel columns & posts from survey to sign-off. Our coverage runs across Monmouthshire, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.
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.
Worth knowing before you start
- 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.
- 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.
- 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.
- 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.
- 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.
From survey to sign-off in Caldicot
Free visit
A short visit to Caldicot 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
We submit the application or notice to Monmouthshire County Council under the Building Regulations as they apply in Wales, before work starts.
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.

| Steel column or post | £460–£1,360 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| Basement or cellar steelwork | £2,300–£5,900 | Beams and columns with pad foundations under the floor above (excavation and waterproofing extra) |
| Fire protection to a steel beam | £140–£550 per beam | Fire-rated board boxing or an intumescent coating system as specified |
| RSJ supply and fit (single beam) | £730–£2,280 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |

Building rules for Caldicot
Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Caldicot the application goes to Monmouthshire County Council or a registered building control approver, with the engineer's calculations, and a completion certificate follows the final inspection.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.
Steel columns & posts in Caldicot: your questions
What happens at the survey visit in Caldicot?
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.
Do you also work near Caldicot?
Yes. We also cover nearby towns including Chepstow, Cwmbran, Pontypool and Risca.
Can a steel column be left exposed?
Yes, many people leave a column on show, painted to suit the room. In homes exposed steel commonly needs fire protection, often intumescent paint applied to the specified thickness as part of a compatible paint system. Building control checks the protection meets what was specified. Boxing in with fire-rated plasterboard is the alternative where a hidden column is preferred.
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.
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.
How soon can steel columns & posts start in Caldicot?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
