FAQ

Damp and timber questions, answered.

Straight answers to the questions homeowners and landlords ask us most.

  • Rising damp usually shows as a tide mark low on the wall with salting and blown plaster. Condensation tends to appear as black mould in corners, around windows and behind furniture. Only moisture profiling on site can confirm which mechanism is at work.

Still unsure what you're dealing with?

Damp, condensation and timber problems can look very similar. A professional survey identifies the actual cause.
