County Londonderry: walls, weather and approvals
Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Londonderry 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 stone and early brick properties in County Londonderry, lime render is often the right answer.

Permissions in Northern Ireland
In Northern Ireland, permitted development is set by the Planning (General Permitted Development) Order (NI) 2015. Changing the external appearance of a house may need permission, and conservation areas, flats, commercial buildings and listed buildings need planning permission or listed building consent. Check with your council's planning office.
Insulating external walls is building work under the Building Regulations (Northern Ireland) 2012, handled by council building control, with Technical Booklet F1 covering conservation of fuel and power in dwellings.
Why use lime instead of cement?
Cement render is hard and relatively impermeable. On older walls built with lime mortar, it can crack, let rain in at the cracks and then stop the wall drying, leading to damp patches inside and spalling stone or brick. Lime is softer, more flexible and vapour-open, so moisture can escape.

Lime render in County Londonderry: questions
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.
Can lime render be applied in winter?
Only with protection and in frost-free conditions. Spring to early autumn is the usual season.
Is lime render more expensive?
Usually, because it's applied in coats by hand and needs more curing time.
