Condensation & Mould

What Is Condensation?

Condensation is the most common cause of damp in homes — especially during colder months. It happens when warm, moisture-filled air comes into contact with cold surfaces (like windows or external walls), causing water droplets to form.

If left untreated, condensation can lead to persistent black mould growth, damage to internal finishes, and even health issues such as allergies and respiratory problems.

Why Does Mould Form?

Mould thrives in damp, poorly ventilated environments. Everyday activities like cooking, bathing, and drying clothes indoors release moisture into the air. Without adequate ventilation, this moisture builds up and settles on cold surfaces — creating the ideal environment for mould spores to grow.

Common Signs of Condensation & Mould

• Steamed-up windows and water pooling on sills

• Black or green mould on walls, ceilings, or around windows

• Peeling paint or wallpaper

• Damp or musty smells in certain rooms

• Visible surface damp, especially in corners or behind furniture

• Cold, poorly ventilated rooms (especially bedrooms and bathrooms)

How We Assess Condensation & Mould Problems

We offer a specialist Condensation & Mould Assessment to identify the root causes and provide practical, cost-effective solutions — not just surface-level advice.

Our survey includes:

• Humidity and temperature readings

• Thermal imaging to identify cold bridging and insulation issues

• Ventilation checks (including extractors, vents, and trickle systems)

• Inspection of affected rooms and moisture-prone areas

• Lifestyle review (if applicable) to assess contributing factors

We’ll also explain the difference between condensation and other damp types — so you’re not paying for unnecessary treatments.

Independent Advice, No Sales Agenda

Unlike some companies, we don’t sell mould treatments or ventilation systems, so our advice is 100% independent. We focus on finding the real cause and offering practical, long-term solutions — tailored to your property and budget.

You’ll receive a clear written report outlining:

• The cause of condensation and/or mould

• Recommendations to resolve the issue (ventilation, insulation, heating adjustments, etc.)

• Ongoing prevention advice to stop it returning
