About our basement & cellar steels service in Inverclyde
Basement and cellar steels are the beams and columns that hold up the house above when walls are removed, openings are formed or new space is dug out below ground level. They carry the ground floor and walls down to new foundations, and are installed in a sequence set out by a structural engineer, alongside underpinning, excavation and waterproofing.
We carry out basement & cellar steels throughout Inverclyde, for homeowners, landlords and builders who need the structural part done properly. Coverage takes in Greenock and everywhere in between. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.
What to expect
- 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.
- Basements can stay damp even with waterproofing in place, so steel used below ground is protected against corrosion as the engineer specifies. That might mean an upgraded paint system or galvanising, particularly where steel sits close to external walls.
- 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.
- 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.
- Basement projects run for weeks rather than days, and the steel goes in at set points during the dig. Noise, spoil removal and deliveries peak during excavation, and with careful planning the house above can often stay occupied.
How the job runs in Inverclyde
Free visit
A short visit to Inverclyde 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 Inverclyde 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.

Approvals in Inverclyde
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 Inverclyde, warrants are handled by Inverclyde Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.
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 by town
Local questions answered
Do I need a party wall agreement for basement & cellar steels in Inverclyde?
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.
Do you cover Inverclyde for basement & cellar steels?
Yes. We carry out basement & cellar steels in Inverclyde. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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 planning permission to convert a cellar?
Converting an existing cellar into living space usually does not need planning permission if the outside of the house is unchanged, though listed buildings need consent. Digging a new basement, extending under the garden or adding lightwells may need planning permission, and a building warrant is needed either way.
How long does it take to fit steels in a basement?
Each stage of steelwork usually takes a few days, but it happens at several points through a basement project rather than all at once. The overall programme is set by the excavation, underpinning and waterproofing, and the steel is installed whenever the sequence reaches it.
Will columns be needed in my basement?
Quite often. Below ground there may be no suitable wall to support the end of a beam, so a column carries the load down to a foundation. The position can usually be agreed with you at design stage so the column sits within a wall line, a kitchen island or a storage area.
