Damp and mould are among the most misunderstood issues landlords face. With tenants, landlords, and even some professionals offering conflicting advice, it’s easy for myths to spread—and even easier to fall for them. But believing these misconceptions can cost landlords both financially and legally, as well as damage tenant relationships.

In this post, we’ll debunk five common myths about damp and mould, and provide the facts landlords need to tackle these issues effectively. Along the way, we’ll show how Damp, Mould, and Condensation (DMC) surveys and data loggers can provide clarity and actionable solutions.

### Myth 1: Damp and Mould Are Always Caused by Tenant Behaviour

The Myth: If there’s mould in a property, it must be because tenants aren’t ventilating properly, drying clothes indoors, or using the heating sparingly.

The Truth: While tenant behaviour can contribute to damp and mould, the property itself is often at fault. Poor insulation, inadequate ventilation, or defective heating systems can create the perfect environment for condensation and mould to thrive.

The Solution: A DMC survey can help identify whether the problem stems from the property or tenant behaviour. By addressing structural issues such as faulty extractor fans or insufficient insulation, landlords can often prevent damp and mould before it becomes a tenant-related issue.

### Myth 2: Condensation Is Harmless

The Myth: A little condensation on windows is nothing to worry about.

The Truth: Condensation is often the first visible sign of a moisture problem and can quickly lead to damp and mould if ignored. Over time, condensation can damage window frames, walls, and ceilings, reducing the property’s value and increasing maintenance costs.

The Solution: Tackling condensation early is crucial. Proper ventilation and heating, as well as regular inspections, can prevent condensation from escalating into more serious issues. Installing data loggers to monitor temperature and humidity levels provides landlords with the insights needed to maintain ideal property conditions.

### Myth 3: Opening Windows Will Solve the Problem

The Myth: If tenants open their windows regularly, damp and mould won’t occur.

The Truth: While ventilation is essential, opening windows alone is often insufficient to address damp and mould. In colder months, open windows can even exacerbate the problem by cooling surfaces, increasing the likelihood of condensation. Proper mechanical ventilation—such as extractor fans—is usually needed to remove excess moisture from the air.

The Solution: DMC surveys include advanced anemometer testing to ensure mechanical extractor fans are functioning correctly and meeting Building Regulation standards. Upgrading ventilation systems may be necessary to achieve effective moisture control.

### Myth 4: Damp and Mould Only Happen in Older Properties

The Myth: New-build properties are immune to damp and mould.

The Truth: Damp and mould can occur in any property, regardless of age. In fact, new-builds can be particularly susceptible to condensation if they’re tightly sealed for energy efficiency but lack adequate ventilation. Poor construction practices or materials can also lead to penetrating or rising damp.

The Solution: Regular inspections and long-term monitoring using data loggers are essential for both old and new properties. Identifying and resolving moisture issues early helps maintain the property’s condition and value.

### Myth 5: Bleaching Mould Is a Permanent Fix

The Myth: A quick scrub with bleach is enough to eliminate mould for good.

The Truth: While bleach can temporarily remove surface mould, it doesn’t address the underlying cause. Unless the source of excess moisture is resolved, mould will return—and often spread further. In some cases, using bleach can even make the problem worse by masking deeper issues.

The Solution: Tackling the root cause of mould is the only way to ensure it doesn’t return. A professional DMC survey identifies the source of excess moisture and provides targeted recommendations to resolve it permanently.
