Condensation occurs when warm, moist air meets a cold surface or when air movement is restricted. If neglected, it can lead to peeling wallpaper, rotting window frames, and the growth of black mould, which can impact both the building and the health of its occupants.
Dealing with Condensation and Mould in Your Home effectively requires a three-pronged approach: reducing moisture, improving airflow, and maintaining consistent warmth.
1. Reduce Moisture Production
- Laundry Care: Dry clothes outside whenever possible. If drying indoors, use a room with an open window or an active extractor fan.
- Vented Dryers: Ensure these are properly vented to the exterior via a wall duct or window kit.
- Condenser Dryers: Regularly empty the water reservoir and ensure the room is well-ventilated, as these machines still release some warm, damp air during operation.
- Kitchen Habits: Always use lids on pots and pans. This keeps steam contained and reduces the amount of energy needed to heat food.
- Door Management: Keep kitchen and bathroom doors closed when these rooms are in use. This prevents steam from migrating to colder parts of the house where it can condense on cold walls.
2. Improve Home Ventilation
- Window Vents: Keep trickle vents (the small slots at the top of frames) open in all occupied rooms to provide continuous, low-level airflow.
- Daily Airing: Open windows on opposite sides of the property for 5–10 minutes daily. This “cross-ventilation” flushes out stagnant air without significantly cooling the home.
- Mechanical Fans: Use extractor fans in the bathroom and kitchen during and after activities that produce steam.
- Furniture Placement: Leave a small gap between furniture and external walls. Avoid overfilling cupboards to ensure air can circulate behind and around your belongings.
3. Heating and Insulation
- Consistent Warmth: Maintaining a steady, low heat (ideally above 15°C) is more effective at preventing condensation than short bursts of high heat. Warm walls are less likely to collect moisture than cold ones.
- Structural Insulation: Proper loft and wall insulation keeps internal surfaces warmer, reducing the “dew point” where condensation forms.
Your Responsibilities as a Tenant
Under the terms of your Private Residential Tenancy (PRT) agreement, you have a responsibility to use the property in a “tenant-like manner.” This includes Dealing with Condensation and Mould in Your Home by taking reasonable steps to manage moisture levels and prevent dampness from escalating.
Following this guidance helps ensure your home remains healthy and mould-free. Please be aware that if dampness or mould occurs due to a failure to ventilate or heat the property adequately, it may be considered a breach of your tenancy terms. If you notice a leak or structural dampness outwith your control, you must report it to us immediately.
When to Seek Further Help
If moisture persists despite these measures:
- Dehumidifiers: These can actively extract litres of water from the air (note: these do incur electricity costs).
- Identifying Leaks: If you notice localised damp patches that appear regardless of weather or ventilation, it may be a structural issue (such as a leaking pipe or roof). You must report this to us immediately.
