Barmouth, Gwynedd
Damp-Proof Render in Barmouth
Specialist waterproof and salt-resistant render systems for damp-affected and below-ground walls.
Damp-Proof Render in Barmouth is work we take on regularly, and the Gwynedd housing stock is a big part of why.
Across Gwynedd, slate and stone cottages, quarry housing and exposed coastal properties dominates, and extreme driving rain on slate and stone construction is what we are called out to most often.
The area sees among the highest rainfall in the UK with severe exposure, which is the single biggest factor in how long any render lasts here. Snowdonia records some of the highest rainfall in britain, and any non-breathable render on stone here will trap water within a single winter.
When damp-proof render is the right call. Choose a damp-proof system after flooding, alongside DPC works, on below-ground walls, and wherever salt contamination is destroying normal plaster.

FAQs
Damp-Proof Render in Barmouth
How long before I can paint new render?
Through-coloured systems need no painting at all. Sand and cement should cure for around 28 days before masonry paint goes anywhere near it.
Do you take a deposit?
For most domestic jobs we take a deposit to cover materials and scaffold, with the balance on completion. Terms are set out clearly in the written quote.
Can you match my existing render?
Usually, yes. We colour and texture match as closely as we can, though weathered render never matches a fresh batch exactly — we will be honest about how visible a patch will be.
How long before I can decorate?
Allow a minimum of several weeks for the wall to dry, longer after flooding. Decorating too early traps moisture and the finish fails.
Can salt damage come back?
Not if the source of moisture is fixed and a salt-inhibiting system was used. Recurrence almost always means the underlying cause was never resolved.
