Cure coastal condensation and black mould permanently in your Carrickfergus home — fixed prices from £749, fully installed
The historic harbour town of Carrickfergus sits right on the shore of Belfast Lough, and that coastal setting brings damp, humid air that leaves local homes prone to condensation and black mould — especially through the winter. From period homes near the castle to the estates of Greenisland and the seaside cottages of Whitehead, it's a common story.
We install positive input ventilation (PIV) throughout Carrickfergus and the BT38 postcode, plus neighbouring Greenisland, Whitehead, Eden, Kilroot, Woodburn and along the Antrim coast road. For homes without loft access we fit slimline wall-mounted units; everywhere else, a quiet loft unit does the job.
Fitted in around two hours with no mess, PIV continually replaces moist, stale air with fresh filtered air. Most Carrickfergus customers see dry windows and fresher air within days.
