Steel columns & posts in Wellingborough: how it works
Need steel columns & posts in Wellingborough? Wellingborough is around 8.8 miles from Northampton, and we cover both. 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 NN8 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
- 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.
- Hollow sections, either square or circular, give a neat, slim profile and are common where a post stays on show. Universal columns have an H-shaped section and are often used where the post will be boxed in or built into a wall.
- 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.
- 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.
From survey to sign-off in Wellingborough
Free visit
A short visit to Wellingborough 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 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.
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 rules for Wellingborough
For Wellingborough, 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.

Local questions answered
What happens at the survey visit in Wellingborough?
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 I need a party wall agreement for steel columns & posts in Wellingborough?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
Do I need building control for a steel column?
Yes. A new structural column is building work under the building regulations in England and Wales, and needs a building warrant first in Scotland and a building control application in Northern Ireland. Inspectors normally check the foundation excavation and the fixed column before it is covered. We deal with the application, notices and inspection visits.
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.
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 I stay at home while the work is done in Wellingborough?
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.
