We skim over old walls, re-plaster where the old plaster has blown, and board and plaster new walls and ceilings.
We're based in Pontrug, a few minutes from Caernarfon, and we plaster homes across Gwynedd and Anglesey, from Bangor and Y Felinheli to Porthmadog. Gwynedd Construction Ltd has been building in North Wales as a limited company since 2016.
Book a free estimateA fresh, smooth finish over sound walls and ceilings. It's the quickest way to make a tired room look new.
We sheet the floors and furniture first, and clean up before we leave.
Old textured ceilings and walls skimmed flat, so the room looks up to date.
Artex put on before the late 1990s can contain asbestos, so an old textured ceiling should be tested before anyone sands or scrapes it. See the section below.
When old plaster has blown or been damaged, skimming over it won't last. We hack it off and start again.
It's common in older stone houses and terraces, and often part of a bigger renovation.
New stud walls, ceilings, extensions and garage conversions boarded and finished.
Because we build the walls as well, the whole job is done by one team.
After a wall is knocked through, a rewire or new pipework, the walls and ceilings need putting right.
We blend the patches in so you can't see where the work was done.
Taking a wall out first? See knock-throughs.

We tell you how long your room needs before you paint.
Artex and similar textured coatings put on before the late 1990s can contain asbestos.
New plaster needs to dry before you paint it. You'll see it turn from dark brown to an even pale pink. Then use a watered-down mist coat first, so the paint grips and doesn't peel.
