What we look for in Rhondda
We also cover Aberdare and Pontypridd, close to Rhondda. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of Mid Glamorgan fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
For blocks in Rhondda, we start with height, storeys and the planning position, because those decide the system.

Planning and building control in Wales
For homes in Rhondda, the local planning authority decides any borderline cases; changing a brick house to render, or work on flats, usually needs an application in Wales.
Welsh Building Regulations expect walls to be upgraded when a substantial area is renewed, and building control signs the work off.
Wales applies its own external wall fire rules, updated in 2025; on taller residential buildings we specify non-combustible mineral wool systems.
How disruptive is it for residents?
Most work happens from scaffolding outside. Residents may need to allow brief access to extend window cills, vents or flues from the inside. We provide a notice for residents covering dates, scaffold, and how to raise concerns.

Flats and blocks in Rhondda: questions
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Who pays for EWI on a leasehold block?
In England and Wales, usually the leaseholders through the service charge, depending on the lease, and the landlord must follow the Section 20 consultation process for major works.
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Do you cover Rhondda?
Yes — we survey and quote EWI for flats and blocks in Rhondda (CF42) and nearby Aberdare, Pontypridd and Merthyr Tydfil, with a fixed written price before any work starts.
