Condensation & Damp Control

Specialists Across Southern England & Wales

If your home in Bournemouth, Bath, Cardiff, Portsmouth or anywhere along the South Coast is suffering from persistent condensation, black mould spots, or musty smells, you may be dealing with a condensation-driven damp problem.

At Nordic Damp Proofing Ltd we provide expert surveys and specialist treatments to identify the root cause — whether it’s high indoor humidity, poor ventilation or cold surface condensation — and deliver long-term corrective solutions to restore a healthy, dry living environment.

What Is Condensation & Why It Matters

Condensation occurs when warm, moist air in the home meets cold surfaces (such as walls, windows or ceilings), causing water droplets to form and often resulting in surface damp, mould growth and eventually structural or timber damage if left untreated. 
Unlike rising or penetrating damp (which involves moisture entering from ground or outside), condensation is generated internally, and therefore must be controlled by managing humidity, improving ventilation and correcting thermal deficiencies.

If you’re looking at windows covered in droplets, mould on north-facing walls, or constant use of dehumidifiers, don’t wait until structural or timber damage develops. Book a condensation and damp control survey with our local specialists now and let us provide the right diagnosis and solution.

Our Condensation & Damp Control Services

Detailed Condensation Survey

Our PCA-trained surveyors use thermal imaging, humidity testing and moisture meters to determine whether condensation is the primary cause of your damp.

Ventilation & Humidity Solutions

Installation of extractor fans, positive input ventilation (PIV) or whole house ventilation systems to remove excess moisture from the property.

Thermal Improvements & Insulation Advice

We identify cold surfaces or poorly insulated walls/windows that encourage condensation and recommend improvements or remedial finishes.

Surface Drying & Restoration

Once the cause is managed, we treat affected surfaces, remove mould, dry the structure and re-plaster or re-decorate as needed.

Aftercare & Monitoring

Follow-up checks, advice on best use of ventilation and moisture management to help you maintain a healthy internal environment.
