Drying clothes indoors is often unavoidable, particularly during the colder and wetter months. However, wet laundry can release a surprising amount of moisture into the air, increasing indoor humidity and contributing to condensation, damp and mould growth.
If you regularly dry clothes inside your home, knowing how to dry laundry indoors without causing damp can help you keep humidity under control and reduce the risk of mould.
From improving ventilation to using a dehumidifier, there are several simple ways to manage the moisture produced by drying laundry indoors.
Does drying clothes indoors cause damp?
Drying clothes indoors does not automatically cause damp, but it can significantly increase the amount of moisture in the air.
When clothes come out of the washing machine, they can still contain a considerable amount of water. As they dry, this water evaporates into the surrounding air as water vapour.
If the room is poorly ventilated, the moisture has nowhere to go. As humidity increases, the excess water vapour can eventually condense on colder surfaces such as windows, walls and ceilings.
Repeated condensation can create conditions that encourage mould growth and contribute to damp problems.
This is particularly common during winter, when colder outdoor temperatures can make indoor surfaces colder and windows more susceptible to condensation.
How to dry clothes indoors without causing damp
If you need to dry laundry indoors, there are several steps you can take to reduce the amount of moisture that builds up in your home.
1. Use a dehumidifier when drying laundry
One of the most effective ways to manage moisture when drying clothes indoors is to use a dehumidifier.
As your clothes dry, the water contained within them evaporates into the air. A dehumidifier removes this excess moisture, helping to prevent humidity levels from becoming too high.
Position the dehumidifier in the same room as your drying rack, allowing it to remove moisture as the clothes dry.
Modern dehumidifiers with humidity controls can also help maintain a more consistent level of humidity, rather than simply running continuously.
For homes where indoor laundry drying is a regular occurrence, a higher-capacity model such as the Air Pro 25L Digital Dehumidifier can help remove larger amounts of moisture from the air.

2. Improve ventilation
Ventilation is important whenever you are drying clothes indoors.
Opening a window can allow humid air to escape and fresh air to circulate. Extractor fans can also help remove moisture, particularly if your laundry is being dried in a bathroom or utility room.
However, simply opening windows may not always be practical during cold or wet weather. In these situations, a dehumidifier can provide a more controlled way of removing moisture from the room.
Try to avoid drying large amounts of laundry in a completely enclosed room with no ventilation.
3. Give your clothes plenty of space
Avoid overcrowding your drying rack.
When clothes are packed closely together, air cannot circulate effectively between them, which can significantly increase drying time.
Spread clothes out as much as possible and leave space between larger items such as towels, bedding and jumpers.
Better airflow allows moisture to evaporate more efficiently and can help your laundry dry faster.
4. Use a high spin cycle
The more water your clothes retain when they leave the washing machine, the more moisture will eventually be released into your home.
Using an appropriate higher-speed spin cycle can remove more water from your laundry before you put it on the drying rack.
This can reduce drying times and decrease the amount of moisture released into the surrounding air.
Always check the care instructions for your clothes and choose a spin speed appropriate for the fabrics being washed.
5. Dry laundry in one room where possible
If you're drying clothes throughout the house, the moisture released from your laundry can spread between multiple rooms.
Where practical, keep your drying rack in one suitable room and close the door to prevent humid air from spreading throughout the property.
You can then ventilate the room or use a dehumidifier to remove the moisture more effectively.
A utility room, spare room or other well-ventilated space may be preferable to a bedroom or living room.
6. Avoid drying clothes directly on radiators
Putting wet clothes directly on radiators may seem like an easy way to speed up drying, but it can increase the amount of moisture released into the surrounding air.
It can also restrict the circulation of warm air around the room.
Instead, use a drying rack and allow air to circulate around the clothes.
If you need to dry laundry indoors regularly, combining a drying rack with a dehumidifier can provide a more effective approach to managing the moisture released during the drying process.
Can drying clothes indoors cause mould?
Drying clothes indoors can contribute to mould growth if it causes indoor humidity to remain consistently high.
Mould needs moisture to grow, and regularly increasing humidity without allowing the excess moisture to escape can create favourable conditions for mould.
You may notice early signs of excess humidity such as:
- Condensation on windows
- Damp or cold-feeling rooms
- Moisture on walls
- A musty smell
- Mould appearing around windows or in corners
- Clothes taking a long time to dry
If these problems regularly occur when drying laundry indoors, it may be a sign that you need to improve ventilation or introduce additional moisture control.

Where is the best place to dry clothes indoors?
The best place to dry laundry indoors is generally a room with good airflow and sufficient space for the clothes to dry without creating excessive humidity throughout the rest of your home.
Ideally, choose a room where you can:
- Open a window when necessary
- Use an extractor fan or ventilation system
- Keep the door closed
- Position a drying rack away from walls
- Use a dehumidifier
- Avoid placing wet laundry directly against walls or in areas with poor airflow.
Bedrooms can be particularly unsuitable for regular indoor laundry drying because the additional moisture can increase humidity in a room where you spend several hours sleeping.
How long does it take to dry clothes indoors?
The time required to dry clothes indoors depends on several factors, including the temperature, humidity, ventilation, fabric type and amount of laundry.
Thicker items such as towels, jeans and bedding generally take longer to dry than lightweight clothing.
High humidity can also significantly slow the drying process. Once the surrounding air becomes saturated with moisture, less additional water can evaporate from your clothes.
This creates a cycle where clothes take longer to dry while simultaneously adding more moisture to your home.
A dehumidifier can help break this cycle by continuously removing moisture from the air, allowing more water to evaporate from the clothes.
What humidity should my home be when drying clothes?
Keeping indoor humidity at a reasonable level can help reduce condensation and the conditions that encourage mould growth.
Rather than focusing solely on drying your clothes as quickly as possible, it is useful to consider what is happening to the moisture once it leaves your laundry.
A dehumidifier with a built-in humidity sensor can monitor moisture levels and adjust its operation accordingly.
This can be particularly useful during winter when opening windows for extended periods may be impractical.
Should you use a dehumidifier when drying clothes?
If you regularly dry clothes indoors, a dehumidifier can be one of the most effective ways to manage the moisture released by your laundry.
Instead of allowing water vapour to accumulate in the room, the dehumidifier removes moisture from the air and collects it in its water tank or through a continuous drainage system where supported.
For occasional laundry drying, a smaller unit may be sufficient. If you regularly dry large amounts of washing indoors or have an existing condensation or humidity problem, a higher-capacity dehumidifier may be more appropriate.
The Air Pro 25L Digital Dehumidifier is designed for higher-volume moisture extraction and can be used to help manage humidity when drying laundry indoors.
