Loft insulation for Derry properties
Derry is among the towns we cover in County Londonderry, alongside Limavady, Coleraine and Magherafelt. Derry is one of the main towns we cover in County Londonderry.
We check ventilation as carefully as insulation in Derry homes, because both matter for keeping a house dry. Where a Derry home also has empty cavity walls, we can survey those at the same time.
As for paperwork, if cavity wall insulation follows in Derry, inserting cavity wall insulation needs a building control application to the council before work starts.
