Smooth Render Finish in South Glamorgan
Flat, contemporary smooth render — the most demanding finish and the most striking when done right.
Getting smooth render finish right in South Glamorgan depends far more on the substrate and the exposure than on the product name.
South Glamorgan is characterised by Victorian and Edwardian terraces, Cardiff suburban housing and coastal properties, with solid-wall terrace damp and coastal weathering at Barry and Penarth the recurring theme on the properties we survey. With wet with coastal exposure along the Severn estuary, specification matters more in this part of the country than a national price list suggests.
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 smooth render finish right for a South Glamorgan property?
Choose smooth for contemporary architecture and sharp modern detailing — provided the substrate is sound enough to justify it.
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
Smooth Render Finish in South Glamorgan — questions
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.
Does smooth render crack more easily?
It doesn't crack more, but any cracking is far more visible than on a textured surface. Mesh reinforcement and proper movement joints are essential.
What is the difference between smooth and 1.5mm render?
1.5mm has a fine grain that reads as almost smooth at a distance but has a subtle tooth up close. True smooth has no grain at all and is significantly harder to achieve evenly.
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.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
