Q2: How do you damp proof a wall?

Dampness on walls is a very common problem but not every damp problem on a wall is the same, so the appropriate damp proofing can vary. For condensation problems you may simply need to improve ventilation in the property and clean the mould from the wall. Penetrating damp can be treated by fixing a source of water ingress and rising damp can often be fixed by installing or repairing a damp proof course.

Q5: Does putting the heating on help damp?

Not necissarily. If your damp problem is a result of condensation then making your home hotter can contribute to excess humidity. Thats said, you can use your central heating to achieve relative humidity in your home by heating every room of your home so as not to leave cold rooms, which are then more at risk of condensation.

Q6: What is the cause of damp on internal walls?

There area few reasons your internall walls can get damp. Rising damp only affects internal walls on the ground floor of a property and will leave a typical “tide mark” above the skirting board. Condensation is the most common cause of damp internal walls and will usually show signs of black mould. Penetrating damp is another cause of damp internal walls and signs of penetrating damp include damp patches, damaged plaster, water marks on masonry and damp musty smells.
