About our steel columns & posts service in Walton-on-Thames
Our steel columns & posts service in Walton-on-Thames covers everything from the first visit to the completion paperwork. We also work in nearby Woking, roughly 7.8 miles away. Postcode districts we cover here include KT8, KT10, KT12, KT13 and TW16.
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
- 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.
- 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.
- The base plate is welded to the foot of the column and fixed to the pad with holding-down bolts. A cap plate at the top bolts to the beam above, so the two act together and the beam cannot slide off its support.
- 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.
How the job runs in Walton-on-Thames
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.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
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.
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 control and neighbours in Walton-on-Thames
For Walton-on-Thames, 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.
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.

How much do steel columns & posts cost in Walton-on-Thames?
As a guide, budget £560–£1,680 per column including VAT for steel column or post in Walton-on-Thames, 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.
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.
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.
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.
What happens at the survey visit in Walton-on-Thames?
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.
