About our basement & cellar steels service in Forfar

Basement & cellar steels in Forfar are planned around the house, not a standard kit. Our coverage runs across Angus, so nearby villages are included too. We visit, measure and check what the wall carries, then arrange calculations and building warrant before any steel is ordered.

Underpinning and waterproofing are specialist trades, and we coordinate the steelwork with them rather than replacing them. Our part is the engineer's steel design, building standards, temporary propping, and fitting the beams, columns and base plates at the right point in the dig, so the structure is sound before finishes go in.

What to expect

  • Getting steel into a basement means lowering it through a lightwell, a stair opening or a temporary hole in the ground floor. Long beams may be designed in bolted sections so they can be handled in tight below-ground spaces.
  • Cellars often house gas meters, the incoming water main, the electricity supply and old drainage. These are mapped before work starts, gas work must by law be done by a Gas Safe registered engineer, and the electricity network operator may need to move a supply.
  • A basement room needs a safe way out in a fire, which affects the stair, the doors and sometimes an escape window into a lightwell. Steel in the basement ceiling also commonly needs fire protection to the standard building standards asks for.
  • Victorian and Edwardian cellars often have shallow brick walls, vaulted coal stores extending under the front garden or pavement, and little or no damp protection. The engineer checks whether vaults and walls can stay and what new support they need.
  • Converting a cellar into a habitable room is building work needing a building warrant, covering structure, fire escape, ventilation and damp protection. Digging out a new basement may also need planning permission, depending on the council and the scale of the work.

Four stages, one team

  1. Free visit

    A short visit to Forfar to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building warrant

    A building warrant is applied for from Angus Council, and work starts only once the warrant has been granted.

  4. 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 Forfar

Scottish rules are stricter on timing than in England: the building warrant must be in place before the wall is touched. We prepare the application with the engineer's calculations and submit it to Angus Council. The finished work is then certified and a completion certificate submitted for acceptance.

Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.

Basement & cellar steels in Forfar: your questions

Do you cover Forfar for basement & cellar steels?

Do I need a party wall agreement for basement & cellar steels in Forfar?

There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it starts.

Can I stay at home while basement steels are installed?

Many people do, particularly for cellar conversions where the dig is limited. Expect noise, dust and deliveries during the heavier stages, and some rooms above may be out of use while props are in place. For large excavations, moving out for part of the programme can be more comfortable.

Do I need steel beams for a cellar conversion?

Often, yes. If any cellar walls are being removed or opened up, or the ground floor above is being altered for a stair or lightwell, steel beams and columns are usually needed to carry the house above. A structural engineer looks at the layout and loads and specifies the steelwork.

Do you do the underpinning for a basement?

Underpinning is specialist work, and we coordinate the steelwork with the underpinning contractor rather than carrying it out ourselves. The engineer designs the steel and the underpinning sequence together, so beams, columns and new foundations fit the order in which the walls are deepened.

Do you also work near Forfar?

Yes. We also cover nearby towns including Brechin, Carnoustie, Arbroath and Montrose.
