Damp Proofing

Determining the cause of rising and penertrating damp in a property

Hi all, I have a property which looks to be suffering from rising and penetrating damp. It's an end terrace, single brick property, double glazed, central heating with no air bricks installed. In the two upstairs bedrooms one corner in each room is wet to the touch from top to bottom, with what looks like spreading patches at lower levels. In the front sitting room it's the same, although there is a gap between the corner and the other patches (which is why I think there is rising damp and penetrating damp). There is no sign of damp elsewhere in the property. These patches came on quickly (circa 4 days), it's not been raining heavily recently, and they've not appeared during a previously consistent wet period. Any ideas as to what might be causing it? The tenant says they've been keeping it vented and heated so I'm thinking it's not condensation (in many areas you can see the wet on the walls). Thanks, Chris
