Loft conversion steels in Ashford, Surrey: how it works

Our loft conversion steels service in Ashford, Surrey covers everything from the first visit to the completion paperwork. It sits about 8.0 miles from Slough, which we also cover. Postcode districts we cover here include TW15, TW16, TW17, TW18 and TW19.

We fit the steel package for loft conversions, either as part of the full project or alongside your loft builder. That means the engineer's design, building control, getting long steels into a roof space safely, bedding them on padstones and packing them before the new floor and dormer go on.

What to expect

  • Loft steels usually bear on the gable wall in a semi-detached house or on the party wall in a terrace. The engineer checks that the wall below can take the point load and specifies padstones to spread it, sometimes with a steel post down to lower floors.
  • Many loft conversions in houses in England fall within permitted development. Roof extensions facing a road, work in conservation areas, listed buildings and flats generally need planning permission or another form of consent.
  • Traditional cut roofs rely on purlins and struts running down to internal walls. A steel beam can take over that job so the struts come out, freeing up floor and headroom, but the change has to be designed and propped carefully.
  • Many later twentieth-century homes have trussed rafter roofs, with diagonal timbers running through the whole loft. Converting these involves more steel and new timber, because each truss is cut and its load has to be re-routed by design.
  • Headroom in the finished loft depends partly on where the floor steels sit. Setting them low, between the existing ceiling joists, keeps more height upstairs, and the engineer and loft designer agree the levels together.

What happens, step by step

  1. 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.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  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. 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 Ashford, Surrey

For Ashford, Surrey, 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.

Questions about loft conversion steels in Ashford, Surrey

Do you also work near Ashford, Surrey?

Yes. We also cover nearby towns including Staines, Feltham, Sunbury-on-Thames and Hanworth.

Do I need a party wall agreement for loft conversion steels in Ashford, Surrey?

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 loft conversion steels need fire protection?

Usually, yes. Steel loses strength in a fire, and the beams carrying the new floor are elements of structure. In a typical house they commonly need 30-minute fire resistance, often provided by fire-rated plasterboard around and below the steel, as agreed with building control.

Where do loft conversion steels sit?

Usually between the gable walls or party walls, bearing on padstones bedded into pockets cut in the brickwork. Floor beams sit low, close to the existing ceiling, while ridge or dormer beams sit higher up to support the roof. The engineer sets the exact positions and levels.

How long does it take to install loft steels?

The main steels for a typical loft conversion usually go in over two to five working days. That covers cutting pockets, bedding padstones, getting the steel in and packing it. The timing depends heavily on access and how many beams the design calls for.
