Local considerations in Cornwall
The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Parts of Cornwall 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.
Before quoting Cornwall pebble dash jobs, we tap-test each elevation and mark any hollow areas.

Permissions in England
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
When does pebble dash need removing?
Where it's widely hollow, cracked or letting water in, or where the wall underneath needs to be inspected or repaired. Removal is dusty and noisy and can damage the face of soft bricks, so it's not the default.

Cover pebble dash in Cornwall: questions
Will the stones show through?
No. A levelling base coat with mesh fills over the stones before the finish goes on.
Can I paint pebble dash instead?
You can, but it doesn't fix hollow areas or cracks, and paint on dash often needs redoing every few years.
Does covering pebble dash need planning permission?
Changing the finish on a house usually doesn't in England and Wales outside conservation areas, but check if your house is in one or is listed.
Do you cover all of Cornwall?
Yes. We survey and quote pebble dash covering across Cornwall, including Redruth, Falmouth, St Austell, Truro, Camborne.
Do I need planning permission in England?
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. We check your address before quoting.
