A rental property in Swaythling suffered from mould in cupboards and a heavy, humid indoor environment. By repairing the bathroom extractor fan and installing a Positive Input Ventilation (PIV) system, we improved airflow and helped restore a healthier living environment.
Condensation and Mould Problem in a Rental Property in Swaythling
A landlord contacted us regarding a rental property in Swaythling, Southampton, where the tenant had reported mould forming inside cupboards and a generally humid atmosphere inside the home. When entering the property, the air felt noticeably heavy and damp, even though there were no signs of water leaks or direct water ingress from outside.
Tenant Concerns and Living Conditions
The tenant explained that they regularly opened windows and doors to try to ventilate the house. However, because they were not home during the day, moisture would often build up while the property remained closed.
Clothes were frequently dried indoors using a heated clothes dryer, and a portable dehumidifier was being used to help manage humidity levels. While this provided some improvement, it was not enough to prevent condensation and moisture from building up in colder areas of the property.
Signs of Moisture and Early Mould Formation
During our inspection, we noticed cold spots in several corners of the home where small patches of black mould had started to appear. These areas often develop when warm, moist air meets colder surfaces with limited airflow.
Another key issue quickly became apparent: the bathroom extractor fan was not working. Without proper extraction, moisture from showers and baths stays inside the property and spreads to other rooms, increasing the risk of condensation and mould.
Restoring Proper Moisture Extraction
The first step was to restore effective ventilation in the bathroom by replacing the faulty extractor fan. Removing humid air directly at the source is one of the most important steps when dealing with condensation problems in homes.
Why Bathroom Extraction Is Important
Bathrooms produce large amounts of moisture in a short period of time. Without a working extractor fan, that moisture travels through the property and settles on colder surfaces such as external walls, cupboards, and corners of rooms.
By installing a new extractor fan, the humid air from the bathroom can now be removed directly outside, reducing the amount of moisture circulating inside the home.
Installing a Positive Input Ventilation (PIV) System
To further improve airflow throughout the property, we also recommended installing a Positive Input Ventilation (PIV) unit.
How the PIV System Improves Air Movement
The PIV unit was installed on the same floor and works by gently introducing fresh, filtered air into the property. This fresh air helps push stale and humid air out through natural leakage points in the building while improving air circulation around colder areas of the home.
Better air movement helps prevent moisture from settling in corners, cupboards, and behind furniture where mould can develop.
Results After Installation
Within about a week, the difference was already noticeable. The bathroom extractor fan now removes humid air directly after showers, and the PIV system keeps fresh air circulating throughout the property.
A Healthier and Fresher Indoor Environment
The indoor air felt noticeably fresher and lighter compared to the heavy and humid environment present during the initial inspection. Improving ventilation not only helps protect the condition of the property but also supports the health and comfort of the tenants living inside.
If you are experiencing condensation, mould, or stale air in your home, improving ventilation with extractor fans and Positive Input Ventilation systems can often make a significant difference.
