Ventilation & Condensation Surveys

Indoor Air Quality & Moisture Control Across Southern England & Wales

In homes across the South Coast —Dorset, Hampshire, Bristol, Bath and South Wales — poor ventilation and high internal humidity are often the hidden causes of condensation, damp patches and mould growth. At Nordic Damp Proofing Ltd we offer specialist ventilation and condensation surveys to diagnose airflow, humidity and surface-moisture issues and provide detailed insight and recommendations for a healthy, dry living environment.

What, Why & How We Conduct a Ventilation & Condensation Survey

What We Do

We carry out a meticulous inspection of your property’s ventilation systems and condensation risk-factors, including internal moisture dynamics, surface cooling and airflow performance.

Why It Matters

Condensation isn’t just a cosmetic issue — it’s a form of damp that arises when warm moist air contacts cold surfaces, leading to mould, structural moisture damage and compromised indoor air quality. Ensuring correct ventilation and humidity control protects your home, health and investment.

How We Carry It Out

1. Pre-Inspection Review

We gather property background (age, previous works, any perceived issues).

2. Initial exterior check

Wall construction, vents, ground levels, drainage and overall envelope condition.

3. Internal walkthrough

Humidity readings, visual signs of condensation or damp, ventilation system check, thermal imaging for hidden cold-bridges.

4. Data-analysis & report

Compile results, annotate images, assess ventilation effectiveness and recommend solutions tailored to your property’s needs.

If you’ve noticed persistent condensation on windows, black mould spots, musty smells or feel that your home’s ventilation isn’t performing, this survey provides the clarity you need to act. We will visit your property, carry out the required diagnostics, and deliver a professional report so you know what the issues are, how serious they are and what’s required to solve them.

What We Include in a Ventilation & Condensation Survey

External Building Envelope Inspection

We start by assessing the exterior: examining wall construction, roof vents, guttering, ground levels, and any visible defects that could compromise ventilation or allow moisture ingress.

Internal Ventilation & Humidity Assessment

Inside your property we check kitchens, bathrooms, lofts, roof-voids and living areas for signs of poor airflow, condensation deposition, high humidity, and surface damp or mould. We also assess how the current ventilation systems are working (or failing).

Diagnostic Measurements & Thermal Imaging

We use humidity/temperature sensors, moisture meters, and thermal imaging cameras to map cold spots, dew-point risks, moisture accumulation and ventilation lapse. For example, elevated humidity combined with cold surfaces indicates condensation risk.

Comprehensive Written Report with Photos and Recommendations

Following the survey you receive a complete report with annotated photographs, findings on ventilation performance, identified condensation risk areas, and clear, practical next-step recommendations for improving airflow, managing moisture and reducing mould risk.
