Damp within homes is a very common issue. A high amount of damp caused in properties is due to 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 houses often have bad ventilation and mixed with poor use of heating can result in condensation problems.
Some properties may have been built without a DPC or those that have been built with one, may find this is no longer working to its full capacity because of changes in ground levels, damage from building renovations or frequently with buildings built on sloping site and hills, the older damp proofing measures are no longer working well enough to meet our modern day standards.
