What steel goalpost frames involve in Hatfield

Hatfield has a mix of housing, and steel goalpost frames need a slightly different approach in each. Hatfield is around 10.5 miles from Watford, and we cover both. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

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.

Things to plan for

  • 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.
  • Columns are commonly universal columns or square hollow sections, welded to steel base plates at the foot and cap plates at the head. Holding-down bolts fix the base plates to the pad, and grout fills the gap beneath once the frame is level.
  • Column pads can clash with drains, gas pipes and underfloor heating runs below the floor. These are located before digging, and if a drain runs where a pad needs to go, the engineer may move the column or redesign the pad.
  • Columns can be boxed in with fire-rated plasterboard to look like small piers, built into new stud walls, or left exposed and painted. Where an extension wall continues past the opening, a column can often sit within it out of sight.

From survey to sign-off in Hatfield

  1. Survey in Hatfield

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. 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.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building control and neighbours in Hatfield

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

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.

Steel goalpost frames near Hatfield

Local questions answered

Do you also work near Hatfield?

Yes. We also cover nearby towns including Welwyn Garden City, St Albans, Potters Bar and Hertford.

Can you work on older or listed homes in Hatfield?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

Are goalpost frames welded or bolted?

Most domestic goalposts are bolted, with plates welded to the beam and columns in the fabrication shop and bolted together on site. That lets each piece be carried into the house separately. The engineer specifies the connection details, including whether the joints need to resist sway, and the fabricator makes the frame to suit.

Can a goalpost frame be hidden?

Usually, yes. The columns can be boxed in with fire-rated plasterboard so they read as small piers, set inside new walls, or hidden within the line of an extension's side walls. The beam is boxed like any other steel. Some owners prefer to leave the frame exposed and painted as a design feature.

Is a goalpost frame more expensive than a beam?

Generally yes, because there is more steel, more fabrication and new foundations to dig and pour. Against that, a goalpost can avoid rebuilding weak piers or strengthening walls so they can take a beam. Our itemised written quote shows the frame, pads, propping and making good separately so you can see where the cost sits.
