Will Putting The Heating On Fix Damp?

Within the UK, dampness is an all-too-familiar struggle for homeowners. Faced with this persistent problem, property owners often seek simple and cost-effective solutions to try and remedy the dampness, and one question frequently arises: Will putting the heating on and warming our living spaces fix dampness? 

Damp tends to strike in colder environments, and while heating can nullify dampness issues temporarily, it is only a short-term solution, meaning a more serious and permanent solution should occur. Employing heating to maintain warmth within a property is crucial, as it aids in impeding the spread of dampness. 

In this article, we will take a look at how putting the heating on can temporarily mitigate the issues of dampness, as well as looking at more permanent and long-term solutions that will fix the problem completely.

How Turning The Heating On Can Mitigate Issues Related To Damp

Turning the heating on in your home can be a proactive step in nullifying various issues associated with dampness. By maintaining a consistent level of warmth, you can effectively combat the process of condensation, a primary factor in damp problems occurring. 

Condensation occurs when warm air with lots of moisture comes into contact with cooler surfaces, such as walls or windows, leading to water droplets forming. This moisture accumulation can encourage the growth of mould and mildew, causing stains and potential health hazards. 

However, by heating your home, you can increase the temperature of these surfaces, reducing the likelihood of condensation occurring. Additionally, heating helps airflow and ventilation within the property, further aiding in drying out damp areas and preventing moisture buildup. 

While turning on the heating is not a standalone solution for damp issues, it serves as a crucial step in slowing down the process of dampness.

What To Do After Putting The Heating On

After turning on the heating to address dampness in your home, there are several important next steps to take to further combat damp-related issues. 

Firstly, it’s important to identify and address any underlying causes of dampness, such as leaks, poor ventilation, or structural issues. Conduct a thorough inspection of your property to pinpoint areas of concern and take appropriate action to rectify them. This is recommended to be done by experts who can provide specialist damp surveys. Further work may involve repairing damaged seals around windows and doors, installing extractor fans in moisture-prone areas like kitchens and bathrooms, or addressing any plumbing leaks promptly.

Additionally, consider implementing strategies to improve ventilation throughout your home. This can help to reduce moisture buildup and improve air quality, ultimately preventing dampness from reoccurring. Simple measures such as opening windows regularly, using dehumidifiers, and ensuring that air vents are unobstructed can make a significant difference in controlling dampness.

Regular maintenance and upkeep of your heating system are also essential. Ensure that your boiler is serviced annually by a qualified professional to maintain optimal performance and efficiency. Also, clean or replace air filters as needed.

Finally, monitor the humidity levels in your home regularly. Investing in a hygrometer can help you keep track of moisture levels and identify any areas where dampness may be a concern. Aim to maintain indoor humidity levels between 30% and 50% to create a comfortable and healthy living environment while minimising the risk of dampness.

By taking these proactive steps after putting the heating on, you can effectively address dampness issues in your home and create a more comfortable, healthier living environment for you and your family.

Will Putting The Heating On Help with Mould?

Heating can aid in reducing the moisture content in the air and on surfaces, which can ultimately slow down the growth of mould. 

However, it’s essential to recognise that heating alone may not fully eliminate mould or address the underlying causes of dampness. Mould thrives in environments with high humidity levels and moisture, so simply heating a damp space without addressing the source of moisture is unlikely to provide a long-term solution. To effectively combat mould caused by dampness, it’s crucial to identify and rectify any issues contributing to excess moisture in the home, such as leaks, poor ventilation, or insulation problems.


In conclusion, the relationship between heating and dampness in homes is fairly complex. While heating can certainly play a role in mitigating damp-related issues such as condensation and mould growth, it is not a standalone solution. To effectively combat dampness, homeowners must take an approach that addresses the underlying causes.


Can I use a dehumidifier instead of heating to combat dampness?

Dehumidifiers can be effective in reducing humidity levels, but heating also helps by increasing air circulation and surface temperatures, making it a complementary approach to dampness management.

How do I know if dampness is caused by condensation or other factors?

Condensation typically occurs in areas with poor ventilation, such as bathrooms and kitchens, while other types of dampness may be caused by leaks or rising damp. A thorough inspection by a professional can help identify the root cause.

Will keeping windows open during winter help prevent dampness?

While ventilation is important, keeping windows open during colder months can lead to heat loss and may not be the most effective way to control dampness. Consider using extractor fans or trickle vents for ventilation instead.
