Condensation around the home

You may have noticed condensation in your London property. But what causes it?

During winter months when the central heating is on, moisture in the warm air indoors will condense on the cool surface of any glass or metal. This is particularly noticeable on older single-glazed windows and doors.

In the summer, properties are normally less prone to condensation, due to the increased ventilation from open windows and doors, plus the fact that there is less difference in the temperature inside and out.

What if there is excess condensation?

Sometimes properties experience more condensation than is usually expected. This is displayed by the following symptoms:

  • Obvious amounts of water pooling on window ledges
  • Metal surfaces away from outer walls showing dampness
  • A cold and clammy feeling to the air in the property
  • Mould beginning to accumulate on walls & ceilings

In cases like these, there may be an issue with the ventilation and air flow around your property. The team at London Damp Proofing can diagnose and suggest improvements, once we've visited to evaluate the root cause.

What are the steps to reducing condensation?

The primary cause of a damp home or office is water leaking into the building, or entering from outside.

Common sources of water ingress are:

  • Broken or missing gutters and downpipes
  • Cracked/damaged roofs or missing roof tiles
  • Leaking water pipes or central heating
  • Inadequate ventilation
  • Faulty drainage systems
  • damage to brickwork and pointing

We would also advise caution when installing cavity wall insulation, particularly in properties that are unsheltered, face regular driving rain or have poor brickwork.

Some types of insulation can decrease airflow around a property, but more importantly will bridge the gap between the outer walls and the inside, allowing water to 'wick' through during wet weather.
