Damp-Proof Render in Caernarfon
Specialist waterproof and salt-resistant render systems for damp-affected and below-ground walls.
We carry out damp-proof render across Caernarfon and the surrounding Gwynedd area throughout the year.
Most of what we see around Caernarfon reflects the wider Gwynedd pattern — slate and stone cottages, quarry housing and exposed coastal properties, and extreme driving rain on slate and stone construction.
Local conditions bring among the highest rainfall in the UK with severe exposure, and that has a direct bearing on which systems are worth specifying. 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 Caernarfon
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.
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
