What Causes Damp?

Damp problems come in many forms but the most common is condensation due to insufficient ventilation. Damp in a house can also be caused by rising damp, penetrating damp or leaking pipes.

The key to getting rid of damp from your house is correctly identifying the damp problem your property is suffering from and applying the correct damp treatment.

What type of damp is affecting my house?

If you are unsure what type of damp is affecting your house, then the quick guides below will help you spot the signs of three common damp problems:

What causes condensation in a house?

Condensation is caused by excess moisture in the property which has not been sufficiently ventilated. When warm moist air lands on cool surfaces such as walls, ceilings and window sills it can lead to dripping wet surfaces and black mould growth. While it is possible to clean black mould without the need to contact a damp proofing company, it is important to establish the cause of condensation to prevent more black mould from forming in the future. Simple lifestyle changes are often enough to tackle a condensation issue. Bathrooms and kitchens are often prone to damp problems due to excess moisture created from cooking and showering.

To combat condensation we would recommend:

  • Opening windows when showering and cooking
  • Keeping lids on pans with
  • Turn on extractor fans
  • Dry clothes outside where possible or use a tumble dryer or
  • If you must dry clothes inside do it in a room with the door closed and windows open.

Occasionally professional help is needed to stop a condensation problem, with mechanical ventilation units available, but we would always recommend trying a DIY approach first.

What causes penetrating damp in a house?

Penetrating damp occurs when moisture seeps from the outside of a building to inside the property. Penetrating damp is often a result of defects in a building such as gaps in windows or gutters, cracks in pipes and defective roofing. If moisture is allowed to penetrate the property, it often leads to damp patches on walls that are more apparent after periods of rainfall. Damp on walls may also be accompanied with a damp musty smell.

To treat penetrating damp, the most important issue is establishing the route of the moisture ingress and amending the crack or leak. Once the source of moisture has been removed, the damage caused by the penetrating damp can then be treated.

What causes rising damp in a house?

Rising damp is caused by moisture moving up from the ground outside of a property and into the ground-floor walls of the building. More often than not, rising damp occurs when a damp proof course in the buildings brickwork has failed.

Signs of rising damp include:

  • Salt marks on the wall
  • Damp tide marks
  • Damaged skirting boards and plaster

It is important to note signs of rising damp will only be apparent up to a metre above the skirting board on the ground floor of a property.

Rising damp is often misdiagnosed so it is important to have any potential signs of damp inspected by a professionally trained damp surveyor who will be able to confirm whether or not the property is suffering from rising damp.
