About our basement & cellar steels service in Worthing
If you live in Worthing, basement & cellar steels can usually be planned and priced after a single survey visit. We also work in nearby Brighton, roughly 10.3 miles away. We cover BN11, BN12, BN13, BN14 and BN15, and we fix the price in writing once the layout and scope are agreed.
Turning a cellar into a habitable room, or digging a new basement, nearly always means moving or removing walls that hold up the rest of the house. Steel beams and columns take over that support, often while the existing walls are being deepened by underpinning and the space is protected against water.
What to expect
- 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.
- Keep the engineer's calculations, waterproofing details, any party wall documents and the completion certificate together. Basement conversions attract questions from buyers' surveyors and lenders, and a complete paper trail makes those questions easier to answer.
- Below-ground rooms need a waterproofing design, often a cavity drain membrane, a tanking system or both. Column bases and beam bearings that pass through the waterproofing are detailed so they do not become a route for water.
- 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.
- Basement steel frames often rely on columns because there is nowhere else to land the load. Each column sits on its own foundation or a thickened part of the slab, and its position needs agreeing early so it does not end up in the middle of a room.
How the job runs in Worthing
Survey in Worthing
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.
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.
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.
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 rules for Worthing
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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.

Do you cover Worthing for basement & cellar steels?
Yes. We carry out basement & cellar steels in Worthing and the BN11, BN12, BN13, BN14 and BN15 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
What paperwork will I get for basement steelwork?
You should end up with the engineer's calculations and drawings, the building control completion certificate, the waterproofing details and, where it applied, the party wall paperwork. Keep them together, as surveyors and solicitors usually ask for them when the property is sold or remortgaged.
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.
How much headroom do I need for a basement conversion?
Enough for the finished room to be comfortable and for the stair to meet the building regulations headroom rules. Steel depth affects that, so the engineer may choose a shallower section or set beams within the floor above. Where headroom is too tight, lowering the floor with underpinning may be an option.
What happens at the survey visit in Worthing?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
