A Landlords Guide to dealing with rising damp in your rental property

One of the most common issues that can affect the safety and habitability of your rental property is rising damp. Rising damp occurs when moisture from the ground rises up through the walls and floors of a building, causing damage to the structure and potentially creating a health hazard for your tenants.

In this guide, we will explore the causes of rising damp, its effects on your property, and how to deal with it effectively. By following the advice in this guide, you can ensure that your rental property remains safe and habitable for your tenants.

Causes of Rising Damp

The moisture responsible for rising damp can come from various sources, including groundwater seeping into the foundation, poor drainage around the property, and cracks or holes in the walls or floors. Additionally, high levels of humidity within the property can also contribute to the problem. One of the primary culprits is a damaged or missing damp-proof course (DPC), which is a barrier designed to prevent moisture from rising up from the ground into the building’s structure.

Dealing with rising damp requires a thorough understanding of the causes and effects of the problem. Identifying the signs of rising damp, such as damp patches, discoloured walls, and musty smells, is crucial for landlords to take prompt action and prevent further damage. It’s important to note that untreated rising damp can also lead to health problems for tenants, such as allergies, asthma, and other respiratory issues.

        Effects of Rising Damp

        Rising damp can cause a range of problems for your rental property, including:

        • Damage to the structure of the building
        • Cracking and flaking of plaster and paint
        • Foul odours and musty smells
        • Health hazards such as mould and mildew
        • Reduced energy efficiency of the property

        Dealing with Rising Damp

        If you suspect that your rental property is affected by rising damp, there are several steps you can take to deal with it effectively. These include:

        • Identify the source of the moisture: The first step in dealing with rising damp is to identify the source of the moisture. This may require the services of a professional damp specialist who can carry out a thorough investigation of your property.
        • Repair any damage: Once the source of the moisture has been identified, any damage to the property should be repaired. This may involve replacing damaged or missing DPC, filling cracks or holes in walls and floors, or installing new drainage systems.
        • Treat the affected areas: To prevent further damage and ensure the property is habitable, it is essential to treat the affected areas. This may involve removing damaged plaster or paint, treating the walls and floors with a specialist damp-proofing solution, and allowing the area to dry out completely before any redecoration takes place.
        • Prevent future problems: To prevent rising damp from occurring in the future, it is essential to take preventative measures. This may include improving drainage around the property, tanking the walls, or ensuring that ventilation is adequate, and monitoring the humidity levels within the property.


        • Can rising damp be fixed permanently?

        It really depends. For a long lasting solution, any damp proof course should be subject to regular checks to ensure a damp proof course remains intact and any additional top up works are carried out as required.  Basement properties often require further tanking works over time due to being below ground level.

        • Is rising damp a health hazard?

        Yes it can be, rising damp can be a health hazard as it can lead to the growth of mould and mildew, which can cause respiratory problems and allergies for anyone occupying the property.

        • Who is responsible for dealing with rising damp in a rental property?

        As a landlord, it is your responsibility to ensure that your rental property is free from rising damp and other hazards.


        Rising damp is a common problem that can affect the safety and habitability of your rental property. By identifying the causes of rising damp, understanding its effects, and taking the necessary steps to deal with it effectively, you can ensure that your rental property remains safe and habitable for your tenants. As a landlord, it is your responsibility to provide a comfortable and secure environment for your tenants, and taking proactive steps to deal with rising damp is an important part of fulfilling that responsibility.

        Remember, dealing with rising damp is not only important for the safety and wellbeing of your tenants, but it can also help to protect your investment by preventing long-term damage to your property.
