Structural alterations in Bangor, Gwynedd and Anglesey

Covering Bangor, Gwynedd and Anglesey

We work in Bangor, Gwynedd and Anglesey (LL57) and the places around it, including Llangefni, Caernarfon and Colwyn Bay.

Homes in Gwynedd and Anglesey

Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.

What goes into a structural alteration?

We arrange the structural calculations, support the floors and roof above with temporary props while the wall comes out, install the steel on padstones, then encase it for fire protection and make good. Chimney breast removals and new openings in external walls follow the same process.
