Overview

Black mould is a common issue in rental properties that can pose serious health risks if not addressed promptly. It thrives in damp and poorly ventilated environments, often appearing as dark patches on walls. Understanding how to prevent black mould can help maintain a healthy living space.

Common Symptoms

  • Dark patches on walls
  • Musty smell
  • Allergic reactions such as sneezing or skin irritation

Possible Causes

  • Poor ventilation
  • Condensation buildup
  • Hidden water leaks
  • Structural damp

Safe Checks You Can Do

Here are some steps you can take to identify and prevent black mould:

  • Check the ventilation in each room. Ensure vents are open and not blocked.
  • Look for visible leaks around windows, pipes, and ceilings.
  • Monitor humidity levels using a hygrometer. Aim for levels between 30% and 50%.
Safety Warning: If you suspect a severe mould problem, do not attempt to clean it yourself, as it may release harmful spores. Contact a professional immediately.

When to Call a Professional

Consider calling a professional if:

  • Mould covers a large area
  • An occupant has a respiratory condition

What to Expect

When a professional attends your property, they will assess the extent of the mould problem, identify the cause, and recommend a course of action. This may include treating the mould, repairing leaks, or improving ventilation.

Responsibility Guide

Typically, landlords are responsible for addressing structural and ventilation issues that lead to mould. However, tenants should report issues promptly and maintain proper ventilation to prevent mould growth.

Prevention Tips

  • Use extractor fans in kitchens and bathrooms.
  • Keep windows slightly open to improve airflow.
  • Dry clothes outdoors or use a tumble dryer.
  • Regularly check for leaks and report them to your landlord.
