Local considerations in Caerphilly
We also cover Risca and Pontypridd, close to Caerphilly. It's roughly 9 miles from Caerphilly to Newport (Gwent), the largest town in Gwent. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across Gwent: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
We bring finish samples to Caerphilly surveys so colours can be judged in daylight against your roof and windows.

Approvals in Wales
For homes in Caerphilly, the local planning authority decides any borderline cases; changing a brick house to render, or work on flats, usually needs an application in Wales.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
What texture will it have?
Thin-coat renders come in grain sizes, typically 1–2mm. A 1.5mm grain is a common middle ground: fine enough to look smooth from the street, coarse enough to hide minor imperfections.

Insulated render in Caerphilly: questions
Does insulated render need painting?
Through-coloured silicone and acrylic renders don't need painting. Mineral renders are usually painted with a compatible masonry paint.
How long does insulated render last?
Typically 25–30 years or more with maintenance; the manufacturer's documentation sets the service life for the specific system.
Will my house look different?
Yes, if it was brick or pebble dash. If you want to keep a brick look, a brick-slip finish over the insulation is an option.
Do you cover Caerphilly?
Yes — we survey and quote insulated render in Caerphilly (CF83) and nearby Risca, Pontypridd and Cardiff, with a fixed written price before any work starts.
