Mould is one of the most contentious issues in the rental sector. When black spots appear on bathroom tiles or behind bedroom furniture, a blame game often ensues between tenants and landlords. For those preparing to move out, the presence of mould can be the difference between a full deposit return and a significant deduction. At Tenancy Cleaning, we see firsthand how deep-seated mould issues can complicate the transition between tenancies.

Determining Responsibility: Tenant vs. Landlord

The question of “who is responsible” depends entirely on the root cause of the moisture. It generally falls into two categories:

• The Landlord’s Responsibility: If the mould is caused by structural defects—such as a leaking roof, rising damp, faulty guttering, or pipe leaks—it is the landlord’s legal duty to repair the issue and treat the resulting mould. Under the Homes (Fitness for Human Habitation) Act, landlords must ensure the property is safe.
• The Tenant’s Responsibility: If the mould is a result of lifestyle factors, the tenant is typically liable. This includes failing to ventilate the property (keeping windows closed during showers or cooking), drying laundry on radiators without airflow, or failing to maintain basic cleanliness in high-moisture areas.

How to Avoid Mould-Related Deposit Deductions

If you are at the end of your lease, ensuring your property is mould-free is critical. A dedicated end of tenancy cleaning service provides the deep intervention necessary to rectify these issues before the final inspection:

The Risks of DIY Mould Removal

Many tenants attempt to scrub mould with household bleach just before an inspection. This is often a temporary fix; bleach can sometimes only “mask” the colour of the spores rather than killing them at the root. Furthermore, improper scrubbing can damage paintwork or wallpaper, leading to further claims against your deposit for “damage” rather than “cleanliness.”

Professional cleaners use biocidal products specifically designed to eliminate spores and prevent immediate regrowth. This level of care demonstrates to landlords that you have taken proactive steps to maintain the property’s condition.

Preventative Steps for a Mould-Free Home

To ensure you don’t face these issues in your next home, remember these simple tips: Always use extractor fans in the kitchen and bathroom, keep a small gap between furniture and external walls to allow air to circulate, and maintain a consistent internal temperature to reduce condensation on cold surfaces.
