Cure condensation and black mould permanently in your Antrim home — fixed prices from £749, fully installed
Antrim town sits on the north-eastern shore of Lough Neagh — the largest freshwater lake in the British Isles. All that water on the doorstep means high humidity, and homes across the town regularly suffer with winter condensation, streaming windows and black mould.
We install positive input ventilation (PIV) throughout Antrim and the BT41 postcode, including Parkhall, Stiles, Rathenraw, Massereene, Muckamore and out to Randalstown, Toome, Crumlin and Templepatrick. From older homes to the town's many estates, PIV is the permanent fix.
One quiet unit, fitted in around two hours, gently floods the home with fresh filtered air and forces the damp out. Most Antrim customers see windows running dry within a week.

We install PIV across Antrim and the surrounding area, including:
"Being so close to Lough Neagh, our windows were soaking every morning and the spare room had mould on the ceiling. The PIV system has made a huge difference — windows are dry and the whole house smells fresher. Highly recommend."
