Planning load-bearing wall removal in Blackwood
For homes in Blackwood and the CF81, CF82 and NP12 districts, we handle load-bearing wall removal from survey to sign-off. We also cover the surrounding towns and villages in Caerphilly. The beam is sized by a structural engineer and inspected before it is boxed in.
We handle the whole job: a survey visit, structural calculations from a qualified engineer, building control, temporary propping, the steel itself, and making good afterwards. You get one itemised written quote and one team to deal with from first visit to sign-off.
Things to plan for
- Older homes can hide surprises such as weak lime mortar, timber lintels or a wall with no proper footing. Where the engineer needs something extra, we price it before any work starts rather than after.
- Each end of the beam needs a solid bearing. Padstones spread the point load into the masonry below, and if the wall underneath is weak the engineer may call for a steel column or a new pad foundation instead.
- Steel beams in homes usually need fire protection. That is often fire-rated plasterboard boxing, which also gives a neat finish, or intumescent paint where the steel is left on show.
- The finished opening should be signed off with a completion certificate from building control. Keep it with your house documents, as solicitors ask for it when the property is sold.
- Most single-wall removals in a typical house take two to five working days on site for the structural part. Plastering, drying out and decorating follow on, and building control visits fit around those stages.
What happens, step by step
Survey in Blackwood
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 the application or notice to Caerphilly County Borough Council under the Building Regulations as they apply in Wales, before work starts.
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 Blackwood
Welsh building regulations treat beams and new openings as controlled building work. We apply to Caerphilly County Borough Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.
Load-bearing wall removal in Blackwood: your questions
Can I stay at home while the work is done in Blackwood?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
Do you also work near Blackwood?
Yes. We also cover nearby towns including Gelligaer, Risca, Pontypridd and Pontypool.
Is a steel beam better than a concrete lintel?
For short openings in some walls a lintel can be enough, but wide openings carrying floors or walls above normally need steel. The engineer chooses whatever does the job properly. Steel is common because it carries a lot of load for its depth.
Do I need planning permission to remove an internal wall?
Usually not, because internal alterations to a house are not normally development needing planning permission. Listed buildings are different and need listed building consent, and flats normally need the freeholder's or landlord's written consent.
How long does it take to remove a load-bearing wall?
For a typical house the structural part usually takes two to five working days: propping, taking the wall out, fitting the steel and packing it tight. Plastering and decorating follow once building control has inspected the steel.
How much does load-bearing wall removal cost in Blackwood?

The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
