What is the difference between rising damp and penetrating damp?

Rising damp usually starts at lower wall level when moisture moves up from the ground, while penetrating damp comes through from outside because of defects such as cracks, failed pointing, or leaks. We inspect the pattern and source carefully so you know which issue you're dealing with.

Can you inspect timber problems during a damp survey?

Yes. We can assess timber affected by excess moisture, including signs of decay, woodworm, and dry rot, because damp and timber damage often go hand in hand.

Is a pre-purchase damp survey worth arranging?

It can be very useful if you've noticed staining, mould, peeling finishes, or a musty smell in a property you're considering. A survey helps you understand the likely cause, the extent of the issue, and what remedial work may be needed.

What we look for during a survey

Our survey starts with the pattern of the problem, because tide marks, staining, peeling finishes, and musty smells can each point to something different. We check how moisture may be moving through walls, floors, or adjoining areas, rather than guessing from one visible patch.

Timber is assessed as part of the wider picture too, especially where damp may have encouraged decay and the need for timber preservation. That matters in older homes, rented properties, and buildings where hidden moisture can sit unnoticed for months. We use that detail to give you practical recommendations you can act on with confidence.
