- Often appropriate in conservation settings

Before we quote 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.
Lime work in Cornwall is scheduled for frost-free months so the render cures properly.

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.
Can lime render be insulated?
Yes, using wood fibre boards or insulating lime plasters. These keep the wall breathable while reducing heat loss.

Lime render in Cornwall: questions
Can lime render be applied in winter?
Only with protection and in frost-free conditions. Spring to early autumn is the usual season.
Should I remove cement render from my stone house?
If it's cracked, hollow or trapping damp, often yes. If it's sound and the wall is dry, it may be left. The survey looks at both.
Does lime render need painting?
Traditionally it's limewashed, which is breathable. Modern masonry paints can block vapour, so we'd avoid them.
Do you cover all of Cornwall?
Yes. We survey and quote lime render 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.
