Before we quote in Cardiff
We cover Cardiff and nearby Penarth, Caerphilly and Barry. 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 South Glamorgan: 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 Cardiff surveys so colours can be judged in daylight against your roof and windows.

Permissions in Wales
Householder rules in Wales are similar to England's: in Cardiff, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
In Wales, insulating or re-rendering more than half of a wall's area is treated as renovating a thermal element under Approved Document L (Wales), so building control is involved before work starts.
Can I choose two colours?
Yes. Many owners pick a main colour with a contrasting plinth, entrance surround or bay. Feature bands and recessed details can be formed in the insulation before rendering.

Insulated render in Cardiff: questions
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.
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.
Can insulated render be applied in winter?
Only in suitable weather — typically above 5°C and rising, with no frost or rain during curing. Winter programmes allow for lost days.
Do you cover Cardiff?
