About our steel goalpost frames service in Carshalton
If you live in Carshalton, steel goalpost frames can usually be planned and priced after a single survey visit. The wider London area is covered as well. We cover CR4, SM1, SM2, SM3 and SM4, and we fix the price in writing once the layout and scope are agreed.
When a rear wall is opened almost corner to corner, or the brickwork either side is too thin, cracked or broken up by openings to take a concentrated load, a beam on padstones is not enough. A goalpost frame brings its own supports: two columns carry the beam's ends straight down to new foundations, so the walls around the opening are not relied on.
Key points for your project
- Keep the engineer's calculations, the frame drawings and the building control completion certificate together. They show a future buyer's surveyor how the opening is supported and save questions about the columns when the house is sold.
- In older homes with suspended timber ground floors, the column has to pass through the void to reach the pad. Air bricks, joists and the damp-proof course around each column are considered so ventilation and damp protection are not compromised.
- A goalpost frame usually takes longer than a single beam because the pads need digging, inspecting, pouring and time to gain strength before the columns take load. The engineer sets when the frame can be loaded.
- Each column usually needs its own concrete pad foundation, because a column delivers a heavy point load that an ordinary floor slab or old strip footing may not take. The engineer sets the pad size and depth from the load and the ground conditions found.
- Digging the column pads means breaking through the floor, which is noisier and messier than fitting a beam alone. Floor coverings near the column positions need lifting, and the spoil from the excavations is bagged and removed from site.
Four stages, one team
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 Carshalton
For Carshalton, 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
How much do steel goalpost frames cost in Carshalton?
As a guide, budget £2,550–£7,700 including VAT for steel goalpost frame in Carshalton, based on published UK cost guides adjusted for London prices (+28%). 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.
Does a goalpost frame need foundations?
Yes, in most cases each column needs a concrete pad foundation beneath it. A column concentrates a lot of weight on a small area, and a normal floor slab is rarely designed for that. The engineer sizes each pad, and building control usually inspects the excavation before the concrete goes in.
Can a goalpost column go next to my neighbour's wall?
It can, but in England and Wales it may bring in the Party Wall etc. Act 1996. Digging a pad near a neighbour's building to below the level of its foundations, or fixing into a shared wall, can be notifiable. We arrange notices through a party wall surveyor where needed. There is no equivalent Act in Scotland or Northern Ireland.
How long does it take to install a steel goalpost?
Allow around one to two weeks on site for a typical job. Breaking out and digging the pads, the foundation inspection, pouring concrete and letting it gain strength take up much of that time. Erecting and bolting the frame itself is often done in a day, followed by inspection and boxing in.
