Steel goalpost frames in Renfrew: how it works
If you live in Renfrew, steel goalpost frames can usually be planned and priced after a single survey visit. We also cover the surrounding towns and villages in Renfrewshire. We cover PA1, PA3, PA4 and PA8, 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
- 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.
- Keep the engineer's calculations, the frame drawings and the building standards 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.
- Price depends on the opening width, the loads the beam carries, the number of bolted connections, the depth of the pads and how easily the steel can be carried in. Any redesign after the ground is opened is priced before it goes ahead.
- While the old wall or piers come out, the floor, walls and roof above are held on props and needles. These stay in until the frame is fully bolted, levelled and packed, so the structure is never left without support.
- 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.
How the job runs in Renfrew
Free visit
A short visit to Renfrew 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 warrant
A building warrant is applied for from Renfrewshire Council, and work starts only once the warrant has been granted.
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.

Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.
Building control and neighbours in Renfrew
In Scotland, structural alterations need a building warrant under the Building (Scotland) Act 2003, and work must not start until the warrant is granted. For Renfrew, warrants are handled by Renfrewshire Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.
There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.
Steel goalpost frames in Renfrew: your questions
How much do steel goalpost frames cost in Renfrew?
As a guide, budget £1,800–£5,450 including VAT for steel goalpost frame in Renfrew, based on published UK cost guides adjusted for prices in Scotland (-9%). 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.
Do you cover Renfrew for steel goalpost frames?
Yes. We carry out steel goalpost frames in Renfrew and the PA1, PA3, PA4 and PA8 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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 standards usually inspects the excavation before the concrete goes in.
What is the difference between a goalpost and a portal frame?
A domestic goalpost is a simple version of a portal frame. Both use columns and a beam joined together, but a full portal frame has rigid joints designed to resist sideways loads on its own, as used in steel-framed industrial buildings. In a house, the engineer decides how rigid the goalpost joints need to be for that opening.
What is a goalpost frame in an extension?
A goalpost frame is a steel beam sitting on two steel columns, bolted together so it stands as one unit. In an extension it is usually placed where the old rear wall was, holding up the house above while leaving a wide, clear opening. The columns rest on concrete pads, so the frame does not depend on the surrounding brickwork.
Can I stay at home while the work is done in Renfrew?
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.
