Cardiff: walls, weather and approvals
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.
Low-level impact damage near drives and bins is a typical EWI repair, and we fix it in Cardiff with compatible materials.

Wales: planning and regulations
Most repair and maintenance work needs no planning application. We'll tell you if the scope grows to the point where building control is involved.
What causes EWI to fail?
Most problems start at details: cills that are too short or not sealed, unsealed pipe penetrations, missing drip beads, ground levels too close to the base track, or impact at low level. Where a defect is widespread, we report the likely cause before quoting.

EWI repairs in Cardiff: questions
My EWI was installed under a grant — who repairs it?
First check the guarantee paperwork and contact the original installer or guarantee provider. If that route isn't available, we can quote.
Why is my EWI cracking?
Common causes are missing movement joints, poor mesh overlap, fixing problems or movement in the wall. We look for the cause rather than filling the crack.
Can damaged EWI be patched?
Yes, provided the board behind is dry and sound. Wet or crushed board is cut out and replaced.
Do you cover Cardiff?
Yes — we survey and quote EWI repairs in Cardiff (CF10) and nearby Penarth, Caerphilly and Barry, with a fixed written price before any work starts.
