Homes and walls in County Londonderry
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 County Londonderry re-render jobs, we check whether building control needs notifying for your wall area.

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.
What's involved in stripping old render?
The render is hacked off, usually with breakers, and the debris bagged or skipped. The wall is then inspected: loose bricks, eroded mortar and damp spots are repaired, and the surface is prepared to suit the new system.
