Damp-Proof Render in Gwynedd
Specialist waterproof and salt-resistant render systems for damp-affected and below-ground walls.
Our damp-proof render work in Gwynedd starts with a free survey, because guessing at a render specification is how jobs go wrong.
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. Gwynedd sits in a part of the UK that gets among the highest rainfall in the UK with severe exposure — worth factoring into any render decision.
Local factor. Snowdonia records some of the highest rainfall in britain, and any non-breathable render on stone here will trap water within a single winter.
Is damp-proof render right for a Gwynedd property?
Choose a damp-proof system after flooding, alongside DPC works, on below-ground walls, and wherever salt contamination is destroying normal plaster.
That decision gets made at the survey, not on the phone. We will tell you plainly if a different system would serve the building better — including when a cheaper one would.

FAQs
Damp-Proof Render in Gwynedd — questions
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
Are you insured?
Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.
What areas do you cover?
We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.
Does damp-proof render cure rising damp?
No — it manages the consequences. The damp-proof course or the source of water has to be dealt with separately. The render then holds back residual moisture and salts while the wall dries.
