Cavity insulation for new builds and extensions for Limavady properties
If your property is in Limavady or the BT49 district or nearby Coleraine, Derry and Magherafelt, it is within our County Londonderry coverage. It is around 14 miles east of Derry.
For semi-detached and terraced homes in Limavady, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. A suitable wall in Limavady is usually filled in a single day from outside, with drill holes made good to match the pointing.
Every elevation is judged on its own exposure. Parts of County Londonderry face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
On the rules side, in Limavady inserting cavity wall insulation needs a building control application to the council before work starts.
