Penetrating Damp – Treatment

To remedy penetrating damp, you should:

Ensure that gutters and downpipes are not blocked.
Ensure windowsills are not damaged (cracks may be letting rainwater in) and make sure the drip grooves are not blocked. This can be caused by a build up of dirt and moss. If found to be blocked, make sure to clean them thoroughly.
