How to Reduce Condensation in Your Home

Understanding Condensation

Condensation occurs when warm, moist air meets a cold surface, causing water vapour to turn into liquid water. It's the most common cause of damp in UK homes, particularly during colder months when windows and walls are cooler.

Left untreated, condensation leads to mould growth, which can damage your property and affect your health. The good news? It's often preventable with simple lifestyle changes.

Daily Habits That Help

Ventilation is Key

• Open windows daily for at least 15 minutes, even in winter

• Use extractor fans when cooking and bathing

• Keep trickle vents open on double-glazed windows

• Don't block air vents or chimneys

  
  

Reduce Moisture Production

• Cover pans when cooking to trap steam

• Dry clothes outdoors when possible, or in a well-ventilated room with the window open

• Avoid using unvented tumble dryers indoors

Wipe down wet surfaces after bathing or cooking

Heating Your Home Effectively

Consistent, low-level heating is more effective than short bursts of high heat:

• Maintain a minimum temperature of 15°C in unused rooms

• Heat your home evenly rather than just occupied rooms

• Use thermostatic radiator valves to control room temperatures

• Consider smart heating controls for efficient temperature management

Practical Solutions

Dehumidifiers

A good dehumidifier can remove several litres of moisture from the air daily. They're particularly useful in bathrooms, kitchens, and bedrooms.

Furniture Placement

Keep furniture slightly away from external walls to allow air circulation. This is especially important for wardrobes and beds.

Insulation Improvements

Better insulation keeps internal surfaces warmer, reducing the temperature difference that causes condensation. Consider:

• Loft insulation

• Cavity wall insulation

• Double or triple glazing

• Internal wall insulation for solid walls

When to Seek Professional Help

If you've tried these methods and still have condensation problems, there may be underlying issues such as:

• Rising damp

• Penetrating damp

• Poor building ventilation design

• Structural thermal bridges
