Trickle vents are small adjustable vents built into window frames that allow background circulation. They help reduce humidity build-up, stale air and moisture build-up without needing to fully open the window.

Prices typically start from £70 to replace an existing vent and from £120 to add a vent (where suitable). Multi-window upgrades are often better value.

They can significantly reduce condensation, especially when used correctly. Results depend on water vapor sources (drying clothes, cooking, showers) and overall ventilation in the property.

Not always. Suitability depends on window type and design. Some Viewports allow straightforward replacement; adding new vents can vary by frame and manufacturer.

Improved ventilation can help prevent Fungal Infestation by reducing dampness. Existing fungus should be cleaned/treated and moisture sources managed alongside air circulation improvements.
