What are the causes of damp issues?
The majority of damp caused in homes is a result of poor maintenance, a lack of adequate ventilation and often in older properties, high ground levels can result in the lack of an effective damp proof course.
Modern properties often have very little natural ventilation and combined with multi occupation and poor use of heating can result in condensation damp.
Older houses may have been constructed without a damp proof course or those built with one, may find this is no longer effective due to changes in ground levels, damage from building renovations or often with properties built on sloping site and hills, the older damp proofing measures are no longer working well enough to meet our modern day standards.
The most common causes of damp in the home are:
- Defective rainwater goods
- leaking roofs
- Condensation from poor ventilation
- High ground levels

How long do I need to wait to redecorate after walls have been damp proofed and replastered?
Non vinyl emulsion paint can normally be used after approximately 3-4 weeks. Impervious type wall coverings such as vinyl and washable papers or paints should not be used until walls have fully dried out.
Full drying out may take up to one month for each 25mm thickness of wall. Drying times are dependant upon various factors such as the ventilation provided during the drying period, the room temperature and the extent of dampness initially.
