Mould Removal County Derry

Why Mould Is Common in County Derry Homes

County Derry (Londonderry) sits on the north coast of Northern Ireland, with Derry City at its heart and towns including Coleraine, Limavady, Magherafelt, and Dungiven spread across the county. The Foyle estuary and the north coast bring persistent damp air inland, while the Sperrin foothills create cold pockets where condensation forms readily on internal surfaces during the winter months.

Many Derry homes, from historic walled-city properties in Derry itself to newer developments in Coleraine and Magherafelt, suffer from the same pattern: solid walls or retrofitted insulation that traps moisture from everyday activities. Without proper ventilation, that moisture condenses on cold surfaces and black mould takes root in corners, behind furniture, and around window frames.

Our Mould Removal Solution for County Derry

We do not just treat the visible mould or sell you anti-mould paint. We install Positive Input Ventilation (PIV) systems that address the root cause: trapped moisture. For houses with a loft, the Drimaster unit sits in the roof space and gently pushes filtered, fresh air throughout the home, diluting humidity and stopping condensation before it starts. For flats and apartments without an attic, the Flatmaster unit mounts on an external wall and achieves the same result.

Once installed, the system runs quietly in the background, costs around 25p per week to operate, and requires almost no maintenance. Most Derry homeowners notice a difference within days: dry windows, no musty smells, and mould that does not return.
