Damp proofing specialists: common questions
Is rising damp as common as damp proofing firms suggest?
No. Most diagnosed rising damp turns out to be condensation, a leaking gutter or a bridged damp course, none of which need injection. Pay for an independent survey from someone who is not quoting for the remedial work.
