Load-bearing wall removal in Porthmadog: how it works
We carry out load-bearing wall removal in Porthmadog, covering the LL47, LL48 and LL49 postcode districts. The wider Gwynedd area is covered as well. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
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.
Worth knowing before you start
- Temporary works matter as much as the beam. Props, spreaders and needles carry the house while the wall is out, and they are positioned so the floor below can take them too.
- A beam can sit below the ceiling with a small boxed downstand or be set up into the floor void so the ceiling runs flat. A flush beam usually needs more work to the joists and costs more.
- If the wall carries a chimney breast, a wall upstairs and floor joists all at once, the engineer may specify a heavier beam or two beams side by side. The quote reflects that once calculations are back.
- Cables, pipes, radiators and sometimes gas runs pass through internal walls. These are traced at the survey so they can be rerouted by the right trade before or during the work, not discovered halfway through.
- 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
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.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit the application or notice to Cyngor Gwynedd under the Building Regulations as they apply in Wales, before work starts.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Load-bearing wall removal in Porthmadog: your questions
Do you cover Porthmadog for load-bearing wall removal?
Yes. We carry out load-bearing wall removal in Porthmadog and the LL47, LL48 and LL49 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Can you work on older or listed homes in Porthmadog?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
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.
Can I stay in the house while the wall is removed?
In most cases yes. The work area is screened, floors are protected and the house stays usable, though the rooms either side of the wall will be out of action for a few days and there will be some noise and dust.
What does the price include?
Our written quote is itemised, so you can see the calculations, building control fees, propping, steel, padstones, labour, fire protection and making good set out line by line. The price is fixed in writing once the layout and scope are agreed.
Do I need a party wall agreement for load-bearing wall removal in Porthmadog?
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.
