Damp-Proof Render in South Glamorgan
Specialist waterproof and salt-resistant render systems for damp-affected and below-ground walls.
Damp-Proof Render in South Glamorgan is work we take on regularly, and the South Glamorgan housing stock is a big part of why.
The prevailing picture in South Glamorgan is Victorian and Edwardian terraces, Cardiff suburban housing and coastal properties. That means solid-wall terrace damp and coastal weathering at Barry and Penarth comes up more here than almost anywhere else. Local conditions bring wet with coastal exposure along the Severn estuary, and that has a direct bearing on which systems are worth specifying.
Local factor. Cardiff's victorian terraces are largely solid-wall, and external insulation with a breathable render is the upgrade that suits them best.
Is damp-proof render right for a South Glamorgan 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 South Glamorgan — questions
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.
Is waterproof render the same as tanking?
Related but not the same. Tanking is a higher-specification below-ground system designed to resist water under pressure; waterproof render is for above-ground damp resistance.
