The Foil Test For Rising Damp

Posted by Bob Bulmer on Tue 25th September 2007 at 06:00 AM, Filed in Damp Issues

Condensation can be a problem within the home, but rising damp is a serious problem. How do you tell between the two.

Well there is a clever little test that may help.

1. Identify your damp spot on the wall. Using a hairdryer, dry the area as best you can.

2. Attach some aluminium foil to the dried area and leave overnight.

3. If the foil is wet the next day you can be fairly certain that the problem is condensation.

4. If the foil is dry with the wall below it soaking wet, you can be fairly certain that the house is suffering from rising damp.

5. Generally, if moisture is apparent over 1m from ground level, then the problem will be condensation.
