Underfloor insulation for Carrickfergus properties
Carrickfergus sits in County Antrim, around 9 miles north-east of Belfast. We work across the BT38 district, including nearby Newtownabbey, Larne and Belfast.
Where a Carrickfergus home also has empty cavity walls, we can survey those at the same time. Small measures like this are often among the cheapest per pound saved, and they suit Carrickfergus homes of every age.
In terms of approvals, if cavity wall insulation follows in Carrickfergus, inserting cavity wall insulation needs a building control application to the council before work starts.

Keeping the void ventilated
Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.
