As a landlord, it’s your responsibility to provide high-quality, damp-free housing for your tenants, and to ensure that your property is kept in good repair.
However, this can prove tricky because condensation can be a major contributor to mould and damp problems. If left unresolved, it can lead to severe (and very costly!) damage to housing.
What’s more, there are some upcoming changes to legislation with the introduction of Awaab’s Law, which means that landlords may soon have increased responsibilities to resolve damp and mould issues in a timely manner.
Condensation is when water vapour in the air forms droplets on a cold surface, such as walls and ceilings. It’s typically caused by common household activities such as cooking, bathing and washing, but even people breathing can contribute.
Unfortunately for landlords, it is the most common cause of mould in domestic properties. While condensation itself isn’t a big issue, if it’s not dealt with properly, it can result in damp patches developing which then encourages mould growth.
Damp patches can also cause damage to the fabric of a building, and create an environment where dust mites and mould can thrive - which can negatively affect the health of anyone living in the property.
Even though, in most cases, it is the people living in the property who are causing the condensation, it is your responsibility as the landlord to deal with damp and mould problems as soon as possible.
This is why it’s important to work with your tenants to prevent the amount of condensation that they produce. In turn, it should help to prevent these issues from developing, saving you time and money!
Here are a few recommendations you can make to your tenants:
By asking your tenants to regularly keep a look out for mould and damp patches, not only will this help to keep them safe and healthy, but it should also minimise repair costs if it’s caught early enough.
Even though these are simple steps, tenants may still not oblige so you may need to take matters into your own hands by improving ventilation throughout the property. This is especially advisable for high-value rental property, where a good ventilation system may be an expected commodity.
If damp is not dealt with in a timely manner, a room may need to be replastered, as the water vapour can cause significant damage that cannot be patch-repaired.
According to Rated People, plastering a single room could set you back anywhere between £500 to £1,500, depending on its size.
Toxic mould, however, needs to be removed professionally as it is hazardous to human health, and therefore can be similarly costly too. Checkatrade states that the average cost of removing mould from a whole house in 2023 was £1,200.
It may be a common saying, but in this case it really is true - prevention is better than a cure when it comes to condensation. The most effective way to prevent condensation (and subsequently mould and damp) is to improve airflow.
Make sure that you have good quality, effective extractor fans installed in all areas of the home that generate considerable water vapour, such as kitchens, bathrooms and utility rooms. Fans will remove a good amount of moisture in the air before it is able to spread into the rest of the home.
However, the most effective way to remove water vapour (and any other harmful pollutants) is whole house ventilation. A mechanical heat recovery ventilation (MVHR) system will circulate filtered air from outside into the property while removing moisture-laden air, preventing condensation from building up.
The additional benefit of a MVHR system is that it provides fresh heated air, meaning that it will also help to keep the home warm in winter months. We often find that installing a whole house ventilation unit is considerably cheaper than repairing damage caused by mould and damp, and it also helps the property to feel fresher, healthier and all-round more pleasant to be in!

Modern houses are designed to be more energy efficient to save owners money on their bills, meaning that they typically have high-quality insulation within the walls and roof to prevent heat loss, as well as effective double glazed windows to prevent heat from escaping.
While these improvements in efficiency are great at saving us money, they also make newer homes more airtight - meaning that without effective ventilation, humidity and air pollution levels can rise quickly. This increases the risk of condensation and damp, which can quickly lead to mould.
Condensation forms when the air temperature in the home falls below the ‘dew point’, meaning that the air can no longer hold as much water vapour and it needs somewhere else to go. When this happens, usually when the air meets a cold surface such as a wall or window, the water vapour is deposited, creating condensation.
As a well-insulated, efficient home is able to retain its heat better, there typically will be smaller differences in temperature during the day and night. This means that there is less opportunity for air to come into contact with colder surfaces - which is good news!
However, there is one downside - the flow of air is significantly reduced in a well-insulated, airtight property. This can result in humidity levels rising even quicker, meaning that the dew point of the water can actually become higher - so condensation can form at a higher temperature.
The most effective way to prevent condensation and mould is by using controlled ventilation. Mechanical Ventilation Heat Recovery (MVHR) units work by drawing in fresh air from outside to displace the humid air from indoors, working with extractor fans to combat indoor air pollution.
Our Business Development Executive, Joe Murray, said:
“The downside of making your home more airtight is that you’ll retain more indoor air pollution and could generate more condensation. As a result, we’re seeing more and more people come to us for ventilation solutions after improving their insulation.
“By investing in an efficient ventilation system, you’ll be provided with a constant stream of fresh, clean air in your home while pollutants are filtered out.”If you’re suffering from increased condensation, or have recently invested in efficient insulation and are worried about the lack of ventilation, then get in touch with our team of experts today for a no-obligation consultation.
