Why Sub-Floor Ventilation Is Essential
If you live in a home with suspended timber floors — especially in older properties around Knutsford — proper sub-floor ventilation is absolutely critical. Without enough airflow beneath the floorboards, moisture can become trapped in the void, causing the timber to become damp over time.
This encourages wet rot, fungal decay, and even wood-boring beetle infestations, leading to expensive structural repairs.
The Role of Air Bricks
Air bricks allow fresh air to circulate beneath the floor, helping to:
✅ Keep timber dry
✅ Prevent fungal decay and rot
✅ Reduce condensation beneath the floor
✅ Protect insulation and joists from moisture build-up
But in many homes, these bricks are missing, blocked, or simply not doing enough.
When Do You Need an Upgrade?
You should consider an air brick upgrade if you’ve noticed:
-
Musty smells coming from under floorboards
-
Cold, damp floors
-
Sagging or creaking floor areas
-
Signs of rot, mould, or woodworm
Modern solutions such as periscope vents and through-flow systems can significantly improve underfloor airflow without altering your home’s appearance.
