Damp is excessive moisture within the structure of your home that can cause multiple problems if not resolved as soon as possible.
It’s recognisable as a concentrated patch of moisture or unsightly discolouration, usually accompanied by a musty smell.
Ignoring damp is not a good idea. It damages walls, windows frames, and anyone living in a house with damp could develop health or respiratory problems.
Damp repair isn’t covered by many buildings insurance policies as damp is a gradually occurring issue and would fall within the ‘maintenance and wear and tear’ exclusion.
There are three types of damp; rising damp, penetrating damp and condensation. Let’s take a look at them in more detail.
What is rising damp?
Rising damp is moisture coming up from the ground and rising through the structure of your home.
It is noticeable on the lower parts of walls to a height of about a metre and also across solid concrete floors. Wet weather makes rising damp worse as walls have more water to soak up.
Modern houses are usually constructed with a damp-proof membrane acting as a waterproof barrier under concrete flooring.
In the walls this is referred to as a ‘damp-proof course’. Your building may not have either of these, depending on its age, or your damp-proofing could simply be damaged, leading to instances of damp.
What are the signs of rising damp?
- Appearance of damp stains and patches on walls
- Ironwork shows signs of rust
- Loose or rotting flooring or skirting boards
- Crumbling, flaky or salt-encrusted plaster-work.
