Penetrating Damp

We've put a few photos here of different types of penetrating damp.  Dont forget it can come from all sorts of places - but common causes include:

Ground levels outside are too high - above the top of the floors internally

Rainwater goods discharging against the wall

Water being drawn through soft and porous stone that appears internally

Cracks or holes in mortar joints

Penetrating damp in Edinburgh

This is a classic example of how penetrating damp can be caused.  A stone arched gateway butted up to the house wall, and was not properly flashed to keep water off the join.  It ran down the wall, and was trapped in the structure of the gateway - with nowhere else to go, it emerged inside the house, soaking the hallway wall.

Damp and Condensation

Always research the subject thoroughly.

Check out local companies that claim to be experts in damp issues.  Check their 'qualifications'.  Find out where they live, where they operate from. Would YOU trust these people?  Ask them to explain the various sources of dampness in an old house - ask them how they can tell the difference between rising damp and other sources of water.  Can they actually tell you how 'rising damp' is supposed to work - I can't !
