Curing condensation across Lisburn

Lisburn's housing is a real mix — from older town-centre terraces and the large estates built from the 1960s through the 1990s, to the many modern, highly-insulated new builds going up around the city and its commuter villages. They share one thing: today's airtight homes trap the moisture from everyday living, and that means condensation and mould.

We install positive input ventilation (PIV) throughout Lisburn and the BT27 and BT28 postcodes, as well as nearby Hillsborough, Moira, Dunmurry, Lambeg, Drumbo and the surrounding villages. Whether you're in a 1970s semi or a brand-new detached, PIV is the proven permanent fix.

A single quiet loft or wall unit gently floods the home with fresh, filtered air, pushing damp air out. Fitted in around two hours, most Lisburn customers see dry windows within a week.

Why PIV

The permanent cure for Lisburn damp

Stops Condensation

Clears streaming windows in older terraces and tightly-sealed new builds alike.

Eliminates Black Mould

Holds humidity below the threshold mould needs, so it stops returning for good.

Pennies to Run

Around £10–£15 a year — quieter and cheaper than running dehumidifiers.

★★★★★

"Our new build near Lisburn was getting awful condensation on the bedroom windows despite being well insulated. The PIV unit sorted it within days and the house feels fresher. Tidy, professional job."
