How to Solve Mould and Condensation Issues in Your Home

Dealing with mould and condensation in your home isn’t just annoying—it can be harmful to your health and damaging to your property. At Bennett Roofing, we help homeowners across the UK find long-term solutions to these common issues. Read on to find out how to tell the difference between mould and condensation, why it happens, and how to fix it.

How to Tell If It’s Mould or Condensation

The easiest way to tell the difference is by closely examining the area:

• Mould usually appears as fuzzy black, green, or yellow patches and has a strong, musty odour.

• Condensation appears as visible droplets of water on cold surfaces, such as windows, ceilings, or walls.

It’s important to identify which issue you’re dealing with so you can treat it effectively.

What Is Mould?

Mould is a microscopic fungus that thrives in warm, damp environments. It spreads quickly and can cause serious health problems, especially for people with asthma or allergies. Mould spores can reduce indoor air quality and are known to irritate the lungs, nose, and throat.

What Is Condensation?

Condensation happens when warm, moist air comes into contact with a cooler surface. When this air can no longer hold the moisture, it releases it in the form of water droplets. You’ll often see this after a hot shower, where steam hits cold bathroom tiles or windows.

Why Am I Getting Mould and Condensation?

There are two main reasons:

1. Poor ventilation – Everyday activities like cooking and showering create moisture. Without good airflow, it stays trapped inside.

2. Inadequate insulation – A poorly insulated home causes warm indoor air to clash with cold surfaces, resulting in condensation that can lead to mould.

   
   

How to Prevent Mould and Condensation

Here are some of the most effective ways to tackle the root of the problem:

• ✔️ Install roof tile vents to improve ventilation in the loft

• ✔️ Upgrade your loft insulation to maintain consistent indoor temperatures

• ✔️ Fit vented soffit boards for better airflow through the roofline

• ✔️ Add over-fascia vents for extra ventilation beneath the roof

• ✔️ Upgrade your bathroom extractor fan to remove excess steam

These upgrades can drastically reduce the risk of moisture build-up and protect your home in the long term.

Everyday Tips to Reduce Moisture Indoors

If you're seeing early signs of mould or condensation, start with these quick fixes:

• Open windows while cooking or showering

• Use extractor fans and keep them well maintained

• Dry clothes outside when possible

• Avoid overcrowding rooms with furniture, which limits airflow

These changes can make a difference, but if the problem persists, it may require a more permanent solution.
