Traditional cottages across North Wales are full of charm—but they're often full of condensation and mould too. Thick stone walls, low ceilings, and limited ventilation mean moisture has nowhere to go. That’s where Positive Input Ventilation (PIV) can make all the difference.
At Weather Wise Solutions Limited, we’re seeing a steady rise in cottage owners looking for permanent, low-maintenance solutions to manage indoor humidity—without compromising the character of their home.
Why Cottages Struggle with Ventilation
Older cottages were not built with modern living in mind. Everyday activities like cooking, bathing, or even breathing add litres of moisture into the air. With sealed windows and no extract systems, moisture gets trapped—leading to black mould, damp smells, and peeling paint.
How PIV Systems Solve the Problem
A PIV unit gently introduces filtered, fresh air into the home—usually from the loft space—pressurising the property just enough to force stale, humid air out through natural gaps. The result?
-
Cleaner air and fewer allergens
-
Condensation control without opening windows
-
Lower risk of black mould growth
-
More comfortable humidity levels
And because cottages often lack extract fans or trickle vents, a PIV system fills the gap by acting as a central airflow system.
Part F Support Without Major Works
PIV systems are a smart way to improve compliance with Part F of the Building Regulations, especially when it's not possible to install multiple extract fans in a traditional layout. They can often be retrofitted with minimal disruption, and we only use units approved by trusted suppliers such as PAM Ties.
