Damp proofing FAQs
There are a few visible signs of damp, although it often goes undetected. However, in older or empty properties, this made become detectable through its smell. These include peeling paint and wallpaper, crumbling plaster, mould growth, black spots or spores on walls and ceilings, and rotting skirting boards and flooring.
You should make sure that all signs of damp have gone before you redecorate your walls. If you want to paint your walls with a water-permeable emulsion paint, you can usually do this after 1 or 2 months. For other types of decoration you should wait longer.
Damp is a serious problem, particularly if you live in an old property, because it can lead to structural damage. This will cost you big money and could be very dangerous, to yourself and the property. Take damp seriously and get it inspected and resolved as soon as you discover it!
